     FIELD OF THE DISCLOSURE 
     This application relates to the field of cancer, particularly to CARs targeting CD19 and CD22 B cell antigens simultaneously, via CD19/CD22 antigen-targeting domains and chimeric antigen receptors (CARs) containing such CD19/CD22 antigen targeting domains and methods of use thereof. 
     BACKGROUND 
     Cancer is one of the most deadly threats to human health. In the U.S. alone, cancer affects nearly 1.3 million new patients each year, and is the second leading cause of death after cardiovascular disease, accounting for approximately 1 in 4 deaths. Solid tumors are responsible for most of those deaths. Although there have been significant advances in the medical treatment of certain cancers, the overall 5-year survival rate for all cancers has improved only by about 10% in the past 20 years. Cancers, or malignant tumors, metastasize and grow rapidly in an uncontrolled manner, making treatment extremely difficult. 
     CD19 is a 85-95 kDa transmembrane cell surface glycoprotein receptor. CD19 is a member of immunoglobulin (Ig) superfamily of proteins, and contains two extracellular Ig-like domains, a transmembrane, and an intracellular signaling domain (Tedder T F, Isaacs, C M, 1989, J Immunol 143:712-171). CD19 modifies B cell receptor signaling, lowering the triggering threshold for the B cell receptor for antigen (Carter, R H, and Fearon, D T, 1992, Science, 256:105-107), and co-ordinates with CD81 and CD21 to regulate this essential B cell signaling complex (Bradbury, L E, Kansas G S, Levy S, Evans R L, Tedder T F, 1992, J Immunol, 149:2841-50). During B cell ontogeny CD19 is able to signal at the pro-B, pre-pre-B cell, pre-B, early B cell stages independent of antigen receptor, and is associated with Src family protein tyrosine kinases, is tyrosine phosphorylated, inducing both intracellular calcium mobilization and inositol phospholipid signaling (Uckun F M, Burkhardt A L, Jarvis L, Jun X, Stealy B, Dibirdik I, Myers D E, Tuel-Ahlgren L, Bolen J B, 1983, J Biol Chem 268:21172-84). The key point of relevance for treatment of B cell malignancies is that CD19 is expressed in a tightly regulated manner on normal B cells, being restricted to early B cell precursors at the stage of IgH gene rearrangement, mature B cells, but not expressed on hematopoietic stem cells, or mature plasma cells (Anderson, K C, Bates, M P, Slaughenhout B L, Pinkus G S, Schlossman S F, Nadler L M, 1984, Blood 63:1424-1433). 
     CD22, also known as SIGLEC-2 (sialic acid-binding immunoglobulin-likelectin-2), is 95 kDa transmembrane surface glycoprotein and contains 6 Ig-like C2-type domains and one Ig-like V-type domain (uniprot.org/uniprot/P20273 #structure, accessed Jul. 12, 2017). During B-cell ontogeny, CD22 is expressed on the B-cell surface starting at the pre-B cell stage, persists on mature B cells and is lost on plasma cells (Nitschke L, 2009, Immunological Reviews, 230:128-143). CD22 contains intracellular ITIM (immuoreceptor tyrosine-based inhibition motifs) domains which following the engagement of the B cell receptor for antigen serve to down-modulate cellular activation. Antibody binding of CD22 induces co-localization with SHP-1, and intracellular phosphatase that also serves to down-modulate phosorylation-based signal transduction (Lumb S, Fleishcer S J, Wiedemann A, Daridon C, Maloney A, Shock A, Dorner T, 2016, Journal of Cell Communication and Signaling, 10:143-151). The key point of relevance for treatment of B cell malignancies is that CD22 is expressed in a tightly regulated manner on normal B cells, but not expressed on hematopoietic stem cells, or mature plasma cells, making it a suitable target antigen for B cell leukemias. The expression of CD22 on both adult and pediatric (pre-B-ALL) B cell malignancies has led to exploiting this target for both antibody and chimeric antigen receptor (CAR)-T cell-based therapy (Haso W, Lee D W, Shah N N, Stetler-Stevenson M, Yuan C M, Pastan I H, Dimitrov D S, Morgan R A, FitzGerlad D J, Barrett D M, Wayne A S, Mackall C L, Orentas R J, 2013, Blood, 121:1165-1174) (Wayne A S, Kreitman R J, Findley H W, Lew G, Delbrook C, Steinberg S M, Stetler-Stevenson M, FitzGerald D J, Pastan I, 2010, Clinical Cancer Research, 16:1894-1903. 
     A number of novel approaches to treat B cell leukemia and lymphoma have been developed, including anti-CD22 antibodies linked to bacterial toxins or chemotherapeutic agents (Wayne A S, FitzGerald D J, Kreitman R J, Pastan I, 2014, Immunotoxins for leukemia, Blood, 123:2470-2477). Inotuzumab Ozogamicin (CMC-544, a humanized version of the murine monoclonal antibody G5/44) is an antibody drug conjugate and is currently being evaluated in clinical trials, either as a single agent or given in combination with chemotherapy (NCT01664910, sponsor: M.D. Anderson Cancer Center) (DiJoseph J F, et al., 2004, Blood, 103:1807-1814). As a single agent, outcomes exceeded those seen with standard therapy, although significant liver toxicity was noted (Kantarjian H, et al., 2016, Inotuzumb ozogamicin versus standard therapy for acute lymphoblastic leukemia, New England Journal of Medicine, 375:740-753). Unmodified CD22 therapeutic antibody, Epratuzumab, is also being tested in combination with chemotherapy (NCT01219816, sponsor: Nantes University Hospital). Epratuzumab is a chimeric protein composed of murine CDRs grafted onto a human antibody framework. Although effective in some leukemias, Moxetumomab pasudotox in not in broad clinical development due to problems with both immunogenicity of the bacterial toxin to which the antibody is fused and modest or comparable levels of activity with other agents (see NCT01829711, sponsor: MedImmune, LLC). To date, many of the binding moieties for CD22 employed in CAR constructs utilize a domain derived from these murine antibodies and do not effectively activate T cells that target this CD22 domain (such as the HA22 anti-CD22 binder used as the basis for Moxetumomab pasudotox, see James S E, Greenberg P D, Jensen M C, Lin Y, Wang J, Till B G, Raubitschek A A, Forman S J, Press O W, 2008, Journal of Immunology 180:7028-7038). One anti-CD22 binder that is effective as an anti-CD22 CAR is currently in clinical trial at the National Institutes of Health (NIH), although results have not been published (ClinicalTrials.gov Identifier: NCT02315612, Anti-CD22 Chimeric Receptor T Cells in Pediatric and Young Adults with Recurrent or Refractory CD22-expressing B Cell Malignancies, sponsor: NCI). This binder is based on the m971 fully human antibody developed in the laboratory of one of the inventors in this application, Dr. Dimiter Dimitrov (Xiao X, Ho M, Zhu Z, Pastan I, Dimitrov D, 2009, Identification and characterization of fully human anti-CD22 monoclonal antibodies, MABS, 1:297-303). The m971 domain was proven effective as a CAR in work supervised by another of the inventors in this application, Dr. Rimas Orentas (Haso W, et al., 2013, Anti-CD22-chimeric antigen receptors targeting B-cell precursor acute lymphoblastic leukemia, Blood, 121:1165-1174). 
     The traditional treatment approaches for B-lineage leukemias and lymphomas may involve chemotherapy, radiotherapy and stem cells transplant (see the world wide web at mayclinic.org). High toxicity associated with these treatments, as well as the risk of complications, such as relapse, secondary malignancy, or GVHD, motivate the search for better therapeutic alternatives. The expression of CD19 on both adult and pediatric (pre-B-ALL) B cell malignancies has led to exploiting this target for both antibody and chimeric antigen receptor (CAR)-T cell-based therapy (Kochenderfer J N, Wilson W H, Janik J E, Dudley M E, Stetler-Stevenson M, Feldman S A, Maric I, Raffeld M, Nathan D A, Lanier B J, Morgan R A, Rosenberg S A, 2010, Blood 116:4099-102; Lee D W, Kochenderfer J N, Stetler-Stevenson M, Cui Y K, Delbrook C, Feldman S A, Orentas R, Sabatino M, Shah N N, Steinberg S M, Stroncek D, Tschernia N, Yuan C, Zhang H, Zhang L, Rosenberg S A, Wayne A S, Mackall C L, 2015, Lancet 385:517-28). Moreover, the presence of CD22 antigen on lymphomas (DLBCL, FL), and leukemias (CLL) make it an attractive additional target for efficient tumor elimination and for the prevention of tumor antigen escape. 
     The present standard of care for B-lineage leukemias may consists of remission induction treatment by high dose of chemotherapy or radiation, followed by consolidation, and may feature stem cell transplantation and additional courses of chemotherapy as needed (see the world wide web at cancer.gov). High toxicity associated with these treatments, as well as the risk of complications, such as relapse, secondary malignancy, or GVHD, motivate the search for better therapeutic alternatives. The expression of CD19 on both adult and pediatric (pre-B-ALL) B cell malignancies has led to exploiting this target for both antibody and chimeric antigen receptor (CAR)-T cell-based therapy (Kochenderfer J N, Wilson W H, Janik J E, Dudley M E, Stetler-Stevenson M, Feldman S A, Maric I, Raffeld M, Nathan D A, Lanier B J, Morgan R A, Rosenberg S A, 2010, Blood 116:4099-102; Lee D W, Kochenderfer J N, Stetler-Stevenson M, Cui Y K, Delbrook C, Feldman S A, Orentas R, Sabatino M, Shah N N, Steinberg S M, Stroncek D, Tschernia N, Yuan C, Zhang H, Zhang L, Rosenberg S A, Wayne A S, Mackall C L, 2015, Lancet 385:517-28). 
     A number of novel approaches to treat B cell leukemia and lymphoma have been developed, including bi-specific antibodies that link an anti-CD19 or anti-CD22 binding motif to a T cell binding motif (i.e. Blinatumomab, Blincyto® indicated for the treatment of Philadelphia chromosome-negative relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). To date, many of the binding moieties for CD19 or CD22 employed in CAR constructs utilize a domain derived from murine antibodies. A number of these products are currently being considered for approval including those developed by Novartis and Kite Pharmaceuticals. In April of 2017 Novartis announced that CTL019 (tisagenlecleucel) received FDA breakthrough designation for treatment of adult patients with refractory or recurrent (r/r) DLBCL (diffuse large B cell lymphoma) who failed two or more prior therapies, adding this designation to that for r/r B-cell acute lymphoblastic leukemia (ALL). These indications were based on the Phase II JULIET study (NCT02445248) and the ELIANA study (NCT02435849), respectively. The JULIET trial showed and overall response rate (ORR) of 45%, with a 37% complete response (CR), and an 8% partial response (PR) at three months. In the ELIANA study, 82% of patients infused with the product achieved CR or CR with incomplete count recovery, and the relapse free survival rate at 6 months was 60%. The CAR-T product from Kite Pharmaceuticals (KTE-C19, axicabtagene ciloleucel) was granted breakthrough designation for diffuse large B-cell lymphoma (DLBLC), transformed follicular lymphoma (TFL), and primary mediastinal B-cell lymphoma (PMBCL). In the Kite ZUMA-3 phase II trial of KTE-C19 in r/r ALL, a 73% CR was reported (at 2 months or greater). Whether antibody of CAR-T therapies are utilized, there are still a significant number of patients who are not helped by these therapies, and there is considerable room for improved therapeutic approaches. 
     Chimeric Antigen Receptors (CARs) are hybrid molecules comprising three essential units: (1) an extracellular antigen-binding motif, (2) linking/transmembrane motifs, and (3) intracellular T-cell signaling motifs (Long A H, Haso W M, Orentas R J. Lessons learned from a highly-active CD22-specific chimeric antigen receptor. Oncoimmunology. 2013; 2 (4):e23621). The antigen-binding motif of a CAR is commonly fashioned after an single chain Fragment variable (ScFv), the minimal binding domain of an immunoglobulin (Ig) molecule. Alternate antigen-binding motifs, such as receptor ligands (i.e., IL-13 has been engineered to bind tumor expressed IL-13 receptor), intact immune receptors, library-derived peptides, and innate immune system effector molecules (such as NKG2D) also have been engineered. Alternate cell targets for CAR expression (such as NK or gamma-delta T cells) are also under development (Brown C E et al. Clin Cancer Res. 2012; 18(8):2199-209; Lehner M et al. PLoS One. 2012; 7 (2):e31210). There remains significant work to be done with regard to defining the most active T-cell population to transduce with CAR vectors, determining the optimal culture and expansion techniques, and defining the molecular details of the CAR protein structure itself. 
     The linking motifs of a CAR can be a relatively stable structural domain, such as the constant domain of IgG, or designed to be an extended flexible linker. Structural motifs, such as those derived from IgG constant domains, can be used to extend the ScFv binding domain away from the T-cell plasma membrane surface. This may be important for some tumor targets where the binding domain is particularly close to the tumor cell surface membrane (such as for the disialoganglioside GD2; Orentas et al., unpublished observations). To date, the signaling motifs used in CARs always include the CD3-ξ chain because this core motif is the key signal for T cell activation. The first reported second-generation CARs featured CD28 signaling domains and the CD28 transmembrane sequence. This motif was used in third-generation CARs containing CD137 (4-1BB) signaling motifs as well (Zhao Y et al. J Immunol. 2009; 183 (9): 5563-74). With the advent of new technology, the activation of T cells with beads linked to anti-CD3 and anti-CD28 antibody, and the presence of the canonical “signal 2” from CD28 was no longer required to be encoded by the CAR itself. Using bead activation, third-generation vectors were found to be not superior to second-generation vectors in in vitro assays, and they provided no clear benefit over second-generation vectors in mouse models of leukemia (Haso W, Lee D W, Shah N N, Stetler-Stevenson M, Yuan C M, Pastan I H, Dimitrov D S, Morgan R A, FitzGerald D J, Barrett D M, Wayne A S, Mackall C L, Orentas R J. Anti-CD22-chimeric antigen receptors targeting B cell precursor acute lymphoblastic leukemia, Blood. 2013; 121 (7):1165-74; Kochenderfer J N et al. Blood. 2012; 119 (12):2709-20). This is borne out by the clinical success of CD19-specific CARS that are in a second generation CD28/CD3-ξ (Lee D W et al. American Society of Hematology Annual Meeting. New Orleans, La.; Dec. 7-10, 2013) and a CD137/CD3-ξ signaling format (Porter D L et al. N Engl J Med. 2011; 365 (8): 725-33). In addition to CD137, other tumor necrosis factor receptor superfamily members such as OX40 also are able to provide important persistence signals in CAR-transduced T cells (Yvon E et al. Clin Cancer Res. 2009; 15(18):5852-60). Equally important are the culture conditions under which the CAR T-cell populations were cultured, for example the inclusion of the cytokines IL-2, IL-7, and/or IL-15 (Kaiser A D et al. Cancer Gene Ther. 2015; 22(2):72-78). 
     Current challenges in the more widespread and effective adaptation of CAR therapy for cancer relate to a paucity of compelling targets. Creating binders to cell surface antigens is now readily achievable, but discovering a cell surface antigen that is specific for tumor while sparing normal tissues remains a formidable challenge. One potential way to imbue greater target cell specificity to CAR-expressing T cells is to use combinatorial CAR approaches. In one system, the CD3-ξ and CD28 signal units are split between two different CAR constructs expressed in the same cell; in another, two CARs are expressed in the same T cell, but one has a lower affinity and thus requires the alternate CAR to be engaged first for full activity of the second (Lanitis E et al. Cancer Immunol Res. 2013; 1(1):43-53; Kloss C C et al. Nat Biotechnol. 2013; 31(1):71-5). A second challenge for the generation of a single ScFv-based CAR as an immunotherapeutic agent is tumor cell heterogeneity. At least one group has developed a CAR strategy for glioblastoma whereby the effector cell population targets multiple antigens (HER2, IL-13Ra, EphA2) at the same time in the hope of avoiding the outgrowth of target antigen-negative populations. (Hegde M et al. Mol Ther. 2013; 21(11):2087-101). 
     T-cell-based immunotherapy has become a new frontier in synthetic biology; multiple promoters and gene products are envisioned to steer these highly potent cells to the tumor microenvironment, where T cells can both evade negative regulatory signals and mediate effective tumor killing. The elimination of unwanted T cells through the drug-induced dimerization of inducible caspase 9 constructs with chemical-based dimerizers, such as AP1903, demonstrates one way in which a powerful switch that can control T-cell populations can be initiated pharmacologically (Di Stasi A et al. N Engl J Med. 2011; 365(18):1673-83). The creation of effector T-cell populations that are immune to the negative regulatory effects of transforming growth factor-β by the expression of a decoy receptor further demonstrates the degree to which effector T cells can be engineered for optimal antitumor activity (Foster A E et al. J Immunother. 2008; 31(5):500-5). Thus, while it appears that CARs can trigger T-cell activation in a manner similar to an endogenous T-cell receptor, a major impediment to the clinical application of this technology to date has been limited in vivo expansion of CAR+ T cells, rapid disappearance of the cells after infusion, and disappointing clinical activity. This may be due in part to the murine origin of some of the CAR sequences employed. 
     The use of Blinotumomab (bi-specific anti-CD19 and anti-CD3 antibody) has shown impressive results for the gravely ill patients who have received this therapy. Nevertheless the durable remission rate is less than 40%, and at best only 50% of responders can be salvaged to hematopoietic stem cell transplant (HSCT) (see Gore et al., 2014, NCT01471782 and Von Stackelberg, et al., 2014, NCT01471782, summarized in: Benjamin, J E, Stein A S, 2016, Therapeutic Advances in Hematology 7:142-156). The requirement of patients who have received either bi-specific antibody or CAR-T therapy to subsequently undergo HSCT in order to maintain durable responses remains an area of active debate. Although high responses are reported for CD19 CAR-T trials, some even greater than 90%, if the trials are re-cast as “intent to treat” trials the number may be closer to 70% (Davis K L, Mackall C L, 2016, Blood Advances 1:265-268). The best results at 12 months post-CAR19 treatment reported show a RFS of 55% and OS of 79% in patients who were able to receive the T cell product at the University of Pennsylvania (Maude S L, Teachey D T, Rheingold S R, Shaw P A, Aplenc R, Barrett D M, Barker C S, Callahan C, Frey N V, Farzana N, Lacey S F, Zheng A, Levine B, Melenhorst J J, Motley L, Prter D L, June C H, Grupp S A, 2016, J Clin Oncol 34, no15_suppl (May 2016) 3011-3011). 
     Accordingly, there is an urgent and long felt need in the art for discovering novel compositions and methods for treatment of B-ALL and other CD19 and/or CD22-expressing B cell malignancies using an approach that can exhibit specific and efficacious anti-tumor effect without the aforementioned short comings. 
     The present invention addresses these needs by providing CAR compositions and therapeutic methods that can be used to treat cancers and other diseases and/or conditions.

Although many methods and materials similar or equivalent to those described herein can be used, particular suitable methods and materials are described below. In case of conflict, the present specification, including explanations of terms, will control. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting. To facilitate review of the various embodiments, the following explanations of terms are provided: 
     The term “about” when referring to a measurable value such as an amount, a temporal duration, and the like, is meant to encompass variations of.+−0.20% or in some instances.+−0.10%, or in some instances.+−0.5%, or in some instances.+−0.1%, or in some instances.+−0.0.1% from the specified value, as such variations are appropriate to perform the disclosed methods. 
     Unless otherwise noted, the technical terms herein are used according to conventional usage. Definitions of common terms in molecular biology can be found in Benjamin Lewin, Genes VII, published by Oxford University Press, 1999; Kendrew et al. (eds.),  The Encyclopedia of Molecular Biology , published by Blackwell Science Ltd., 1994; and Robert A. Meyers (ed.),  Molecular Biology and Biotechnology: a Comprehensive Desk Reference , published by VCH Publishers, Inc., 1995; and other similar references. 
     The present disclosure provides for CD19/CD22 antibodies or fragments thereof as well as chimeric antigen receptors (CARs) having such CD19/CD22 antigen binding domains. The enhancement of the functional activity of the CAR directly relates to the enhancement of functional activity of the CAR-expressing T cell. As a result of one or more of these modifications, the CARs exhibit both a high degree of cytokine-induced cytolysis and cell surface expression on transduced T cells, along with an increased level of in vivo T cell expansion and persistence of the transduced CAR-expressing T cell. The CARS of the present disclosure are advantageous in that one CART lentiviral product may be utilized to treat multiple patient populations (i.e. CD19+, CD22+ or double CD19+CD22+ cancer patients), which allows flexibility in circumstances where resources are limited. 
     The unique ability to combine functional moieties derived from different protein domains has been a key innovative feature of Chimeric Antigen Receptors (CARs). The choice of each of these protein domains is a key design feature, as is the way in which they are specifically combined. Each design domain is an essential component that can be used across different CAR platforms to engineer the function of lymphocytes. For example, the choice of the extracellular binding domain can make an otherwise ineffective CAR be effective. 
     The invariable framework components of the immunoglobulin-derived protein sequences used to create the extracellular antigen binding domain of a CAR can either be entirely neutral, or they can self-associate and drive the T cell to a state of metabolic exhaustion, thus making the therapeutic T cell expressing that CAR far less effective. This occurs independently of the antigen binding function of this CAR domain. Furthermore, the choice of the intracellular signaling domain(s) also can govern the activity and the durability of the therapeutic lymphocyte population used for immunotherapy. While the ability to bind target antigen and the ability to transmit an activation signal to the T cell through these extracellular and intracellular domains, respectively, are important CAR design aspects, what has also become apparent is that the choice of the source of the extracellular antigen binding fragments can have a significant effect on the efficacy of the CAR and thereby have a defining role for the function and clinical utility of the CAR. 
     The CARs disclosed herein are expressed at a high level in a cell. A cell expressing the CAR has a high in vivo proliferation rate, produces large amounts of cytokines, and has a high cytotoxic activity against a cell having, on its surface, a CD19/CD22 antigen to which a CAR binds. The use of an extracellular CD19/CD22 antigen binding domain results in generation of a CAR that functions better in vivo, while avoiding the induction of anti-CAR immunity in the host immune response and the killing of the CAR T cell population. The CARs expressing the extracellular CD19/CD22 ScFv antigen binding domain exhibit superior activities/properties including i) prevention of poor CAR T persistence and function as seen with mouse-derived binding sequences; ii) lack of regional (i.e. intrapleural) delivery of the CAR to be efficacious; and iii) ability to generate CAR T cell designs based both on binders with high and low affinity to CD19/CD22. This latter property allows investigators to better tune efficacy vs toxicity, and/or tissue specificity of the CAR T product, since lower-affinity binders may have higher specificity to tumors vs normal tissues due to higher expression of CD19/CD22 on tumors than normal tissue, which may prevent on-target off tumor toxicity and bystander cell killing. 
     What follows is a detailed description of the inventive CARs including a description of their extracellular CD19/CD22 antigen binding domain, the transmembrane domain and the intracellular domain, along with additional description of the CARs, antibodies and antigen binding fragments thereof, conjugates, nucleotides, expression, vectors, and host cells, methods of treatment, compositions, and kits employing the disclosed CARs. 
     A. Chimeric Antigen Receptors (CARs) 
     The CARs disclosed herein comprise at least one CD19/CD22 antigen binding domain capable of binding to CD19/CD22, at least one transmembrane domain, and at least one intracellular domain. 
     A chimeric antigen receptor (CAR) is an artificially constructed hybrid protein or polypeptide containing the antigen binding domains of an antibody (e.g., single chain variable fragment (ScFv)) linked to T-cell signaling domains via the transmembrane domain. Characteristics of CARs include their ability to redirect T-cell specificity and reactivity toward a selected target in a non-MHC-restricted manner, and exploiting the antigen-binding properties of monoclonal antibodies. The non-MHC-restricted antigen recognition gives T cells expressing CARS the ability to recognize antigen independent of antigen processing, thus bypassing a major mechanism of tumor escape. Moreover, when expressed in T-cells, CARs advantageously do not dimerize with endogenous T cell receptor (TCR) alpha and beta chains. 
     As disclosed herein, the intracellular T cell signaling domains of the CARs can include, for example, a T cell receptor signaling domain, a T cell costimulatory signaling domain, or both. The T cell receptor signaling domain refers to a portion of the CAR comprising the intracellular domain of a T cell receptor, such as, for example, and not by way of limitation, the intracellular portion of the CD3 zeta protein. The costimulatory signaling domain refers to a portion of the CAR comprising the intracellular domain of a costimulatory molecule, which is a cell surface molecule other than an antigen receptor or their ligands that are required for an efficient response of lymphocytes to antigen. 
     1. Extracellular Domain 
     In one embodiment, the CAR comprises a target-specific binding element otherwise referred to as an antigen binding domain or moiety. The choice of domain depends upon the type and number of ligands that define the surface of a target cell. For example, the antigen binding domain may be chosen to recognize a ligand that acts as a cell surface marker on target cells associated with a particular disease state. Thus examples of cell surface markers that may act as ligands for the antigen binding domain in the CAR include those associated with viral, bacterial and parasitic infections, autoimmune disease and cancer cells. 
     In one embodiment, the CAR can be engineered to target a tumor antigen of interest by way of engineering a desired antigen binding domain that specifically binds to an antigen on a tumor cell. Tumor antigens are proteins that are produced by tumor cells that elicit an immune response, particularly T-cell mediated immune responses. The selection of the antigen binding domain will depend on the particular type of cancer to be treated. Tumor antigens include, for example, a glioma-associated antigen, carcinoembryonic antigen (CEA), .beta.-human chorionic gonadotropin, alphafetoprotein (AFP), lectin-reactive AFP, thyroglobulin, RAGE-1, MN-CA IX, human telomerase reverse transcriptase, RU1, RU2 (AS), intestinal carboxyl esterase, mut hsp70-2, M-CSF, prostase, prostate-specific antigen (PSA), PAP, NY-ESO-1, LAGE-1a, p53, prostein, PSMA, Her2/neu, survivin and telomerase, prostate-carcinoma tumor antigen-1 (PCTA-1), MAGE, ELF2M, neutrophil elastase, ephrinB2, CD22, insulin growth factor (IGF)-I, IGF-II, IGF-I receptor and CD19/CD22. The tumor antigens disclosed herein are merely included by way of example. The list is not intended to be exclusive and further examples will be readily apparent to those of skill in the art. 
     In one embodiment, the tumor antigen comprises one or more antigenic cancer epitopes associated with a malignant tumor. Malignant tumors express a number of proteins that can serve as target antigens for an immune attack. These molecules include, but are not limited to, tissue-specific antigens such as MART-1, tyrosinase and GP 100 in melanoma and prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) in prostate cancer. Other target molecules belong to the group of transformation-related molecules such as the oncogene HER-2/Neu/ErbB-2. Yet another group of target antigens are onco-fetal antigens such as carcinoembryonic antigen (CEA). In B-cell lymphoma the tumor-specific idiotype immunoglobulin constitutes a truly tumor-specific immunoglobulin antigen that is unique to the individual tumor. B-cell differentiation antigens such as CD19, CD22, CD22, BCMA, ROR1, and CD37 are other candidates for target antigens in B-cell lymphoma. Some of these antigens (CEA, HER-2, CD19, CD22, idiotype) have been used as targets for passive immunotherapy with monoclonal antibodies with limited success. 
     In one preferred embodiment, the tumor antigens are CD19/CD22 and the tumors associated with expression of CD19/CD22 comprise lung mesothelioma, ovarian, and pancreatic cancers that express high levels of the extracellular proteins CD19/CD22, or any combination thereof. 
     The type of tumor antigen may also be a tumor-specific antigen (TSA) or a tumor-associated antigen (TAA). A TSA is unique to tumor cells and does not occur on other cells in the body. A TAA is not unique to a tumor cell and instead is also expressed on a normal cell under conditions that fail to induce a state of immunologic tolerance to the antigen. The expression of the antigen on the tumor may occur under conditions that enable the immune system to respond to the antigen. TAAs may be antigens that are expressed on normal cells during fetal development when the immune system is immature and unable to respond or they may be antigens that are normally present at extremely low levels on normal cells but which are expressed at much higher levels on tumor cells. 
     Non-limiting examples of TSAs or TAAs include the following: Differentiation antigens such as MART-1/MelanA (MART-1), gp100 (Pmel 17), tyrosinase, TRP-1, TRP-2 and tumor-specific multi-lineage antigens such as MAGE-1, MAGE-3, BAGE, GAGE-1, GAGE-2, p15; overexpressed embryonic antigens such as CEA; overexpressed oncogenes and mutated tumor-suppressor genes such as p53, Ras, HER-2/neu; unique tumor antigens resulting from chromosomal translocations; such as BCR-ABL, E2A-PRL, H4-RET, IGH-IGK, MYL-RAR; and viral antigens, such as the Epstein Barr virus antigens EBVA and the human papillomavirus (HPV) antigens E6 and E7. Other large, protein-based antigens include TSP-180, MAGE-4, MAGE-5, MAGE-6, RAGE, NY-ESO, p185erbB2, p180erbB-3, c-met, nm-23H1, PSA, TAG-72, CA 19-9, CA 72-4, CAM 17.1, NuMa, K-ras, beta-Catenin, CDK4, Mum-1, p 15, p 16, 43-9F, 5T4, 791Tgp72, alpha-fetoprotein, beta-HCG, BCA225, BTAA, CA 125, CA 15-3\CA 27.29\BCAA, CA 195, CA 242, CA-50, CAM43, CD68\P1, CO-029, FGF-5, G250, Ga733\EpCAM, HTgp-175, M344, MA-50, MG7-Ag, MOV18, NB/70K, NY-CO-1, RCAS1, SDCCAG16, TA-90\Mac-2 binding protein\cyclophilin C-associated protein, TAAL6, TAG72, TLP, and TPS. 
     In one embodiment, the antigen binding domain portion of the CAR targets an antigen that includes but is not limited to CD19, CD20, CD22, ROR1, CD33, CD38, CD123, CD138, BCMA, c-Met, PSMA, Glycolipid F77, EGFRvIII, GD-2, FGFR4, TSLPR, NY-ESO-1 TCR, MAGE A3 TCR, and the like. 
     In a preferred embodiment, the antigen binding domain portion of the CAR targets the extracellular CD19/CD22 antigen. 
     In the various embodiments of the CD19/CD22-specific CARs disclosed herein, the general scheme is set forth in  FIGS. 1A and 1B  and includes, from the N-terminus to the C-terminus, a signal or leader peptide, anti-CD19/CD22 ScFv (where the CD19 binder is distal to the T cell membrane and the CD22 binder is proximal to the T cell membrane, or where the CD22 binder is distal to the T cell membrane and the CD19 binder is proximal to the T cell membrane), CD8 extracellular linker, CD8 transmembrane domain, 4-1BB costimulatory domain, CD3 zeta activation domain. 
     In one embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 1 (Leader-CD22 VH-(GGGGS)-3 CD22 VL (GGGGS)-5 CD19 VH (GGGGS)-3 CD19 VL CD8 hinge+TM-4-1BB-CD3z (Construct 2219)), and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 2 (Leader-CD22 VH-(GGGGS)-3 CD22 VL (GGGGS)-5 CD19 VH (GGGGS)-3 CD19 VL CD8 hinge+TM-4-1BB-CD3z (Construct 2219). 
     In one embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 1, or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof, and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 2 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof Leader-CD22 VH-(GGGGS)-3 CD22 VL (GGGGS)-5 CD19 VH (GGGGS)-3 CD19 VL CD8 hinge+TM-4-1BB-CD3z (Construct 2219). 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 3 (Leader-CD19 VH (GGGGS)3-CD19 VL-(GGGGS)5-CD22 VL-(GGGGS)3-CD22 VH CD8 hinge+TM-4-1BB-CD3z (Construct 1922) ( FIG. 2 )), and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 4 [Leader-CD19 VH (GGGGS)3-CD19 VL-(GGGGS)5-CD22 VL-(GGGGS)3-CD22 VH CD8 hinge+TM-4-1BB-CD3z (Construct 1922)]. 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 3 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof, and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 4 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof (Leader-CD19 VH (GGGGS)3-CD19 VL-(GGGGS)5-CD22 VL-(GGGGS)3-CD22 VH CD8 hinge+TM-4-1BB-CD3z (Construct 1922)). 
     The surface expression of anti-CD19/CD22 CARs incorporating single chain fragment variable (ScFv) sequences reactive with CD19/CD22 antigen, is shown in Example 2 infra. The expression level for each ScFv-containing CAR was determined by flow cytometric analysis of LV-transduced T cells from healthy donors using one of two detection methods: i) CD22 his, followed anti-his-FL; ii) CD19 Fc recombinant protein, followed by anti Fc-FL. The ScFv-based anti-CD19/CD22 CAR constructs CAR22-19 and CAR19-22 were highly expressed in human primary T cells as compared to non-transduced T cell controls. 
     As shown in EXAMPLE 2 and  FIG. 3 , high cytolytic activity of the CD19/CD22 CARS was demonstrated.  FIG. 3 : Human primary T cells were transduced with LV encoding CAR constructs (CAR 22-19 (LTG2681, D0023), CAR 19-22 (D0024), CAR19 (LTG1538), or CAR22 (LTG2200); see Methods), then incubated for 18 hours with the Raji, REH, K562 or 293T cell lines, stably transduced with firefly luciferase, for luminescence based in vitro killing assays. Raji and Reh leukemia lines express CD19 and CD22 on their surface, while the negative controls, 293T do not. Raji and REH cells were lysed effectively by the tandem CAR 22-19, (LTG2681), tandem CAR 19-22 (LTG2719) and the single-targeting CAR19 (LTG1538) and CAR22 (LTG2200). These results demonstrate target antigen-restricted killing of the single CAR controls and the tandem CD19-targeting CD22-targeting CARs. 
     As an additional specificity controls, 293T-luc lines and A431-luc lines were created that express CD19, or CD20, or CD22 ( FIGS. 4A and 4B ). 293T-19+ were lysed by the CAR 19 (LTG1538) and tandem CAR 22-19 (LTG 2681), but not by CAR22 LTG 2200 or untransduced T cells control ( FIG. 3 ). 293T-CD22+ were lysed by the tandem CAR 22-19 (LTG 2681) and the single CAR20 LTG2200, but not by the single CAR19 (LTG 1538), or untransduced control, demonstrating antigen specificity of the tandem CAR. Finally, no CAR construct lysed the 293T luc CD20 cells, since this antigen was not targeted ( FIG. 4A ). Similarly, A431-luc 19 lines were lysed by tandem CAR LTG2681, or single CAR19 LTG1538, but not CAR22 LTG2200 or UTD control. Vice versa, A431 luc CD22 cells were lysed by tandem CAR 1TG2681 or single CAR22 LTG2200, but not by CD19 CAR LTG1538 or UTD control. Notably, no CAR construct lysed the irrelevant antigen expressing A431-luc CD20 line, because the CD20 antigen was not targeted. ( FIG. 4B ). This results underscores the independent functionality and specificity of each targeting domain of the tandemCAR22-19 ( FIG. 4 ). Moreover, this experiment demonstrates that the tandem CAR 22-19 will be effective against tumor cells even if one of the two antigens (CD19 CD22) was downregulated and is no longer expressed. Therefore tandem CARs, in contract to single CARs, can mitigate tumor antigen escape. 
     The capacity of anti-CD19/CD22 CAR T cells for cytokine secretion was then evaluated ( FIG. 5 ). The CD19+CD22+ Raji tumor cells were co-incubated with the tandem 22-19 CAR T cells (LTG2681) or positive control CAR19 (LTG1538), positive control CAR22 (LTG2200), or negative control untransduced T cells (UTD) at effector to target ratio of 10:1 overnight, and culture supernatants were analyzed by ELISA for IFN gamma, TNF alpha, and IL-2. The tandem CAR 22-19 (LTG2681) strongly induced cytokines in response to tumor cells, whereas the negative control (untransduced, UTD.) yielded no appreciable cytokine induction. Notably, tandem CAR T-expressing cells LTG2681 showed similar levels of IFN gamma, TNF alpha, IL-2, to CAR22 control (LTG2200), and somewhat higher cytokine response than the single CAR19 (LTG1538) control, demonstrating the high potency of the tandem CAR. Importantly, CAR 22-19 produced no cytokine secretion in the absence of tumor cells (CART alone group), which further confirms CAR specificity, and indicates a lack of tonic signaling by the tandem car. 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 60 [CD22-19 CD8 BBz (Construct LTG 2737) ( FIGS. 6, 7, 8 , and  9 , respectively)], and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 61 [CD22-19 CD8 BBz (Construct LTG2737)].

     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 64 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof, and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 65 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof (CD22-19 CD8 ICOSz DNA (Construct D0136)). 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 70 [CD22-19 CD28 CD28z (Construct D0139) ( FIGS. 6, 7, 8 , and  9 , respectively)], and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 71 [CD22-19 CD28 CD28z (Construct D0139)]. 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 70 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof, and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 71 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof (CD22-19 CD28 CD28z (Construct D0139)). 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 76 [CD19 CD8H&amp;TM ICOS z_CD22 CD8H&amp;TM 3z (Construct D0146) ( FIGS. 6, 7, 8, and 9 , respectively)], and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 77 [CD19 CD8H&amp;TM ICOS z_CD22 CD8H&amp;TM 3z (Construct D0146)]. 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 76 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof, and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 77 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof (CD19 CD8H&amp;TM ICOS z_CD22 CD8H&amp;TM 3z (Construct D0146)). 
     In another embodiment, the nucleic acid sequence encoding a CAR comprises the nucleic acid sequence of SEQ ID NO: 62, 66, 68, 72, 74, 78, 80, and 82 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof, and encodes the CAR comprising the amino acid sequence as set forth in SEQ ID NO: 63, 67, 69, 73, 75, 79, 81, and 83 or a sequence with 85%, 90%, 95%, 96%, 97%, 98% or 99% identity thereof. 
     The surface expression of anti-CD22/CD19 CARs incorporating single chain fragment variable (ScFv) sequences reactive with CD22/CD19 antigen, is shown in Example 3 infra. 
     In one embodiment, dual-targeting CAR constructs comprised of different co-stimulatory domains were designed. CAR constructs are listed in Table 1 of Example 3, infra. Schematic representations of CAR design configurations are provided in  FIGS. 6A-D . In some embodiments, the tandem CAR antigen-binding domain, comprised of anti-CD22 ScFv and anti-CD19 scFv sequences, were linked in tandem, in the following order: anti-CD22 scFv-anti CD19-scFv-hinge-transmembrane domain-endodomain ( FIGS. 6A, 6B ). The targeting tandem domain configuration was based on CAR 22-19 (LTG2681) in all cases. Anti-CD 22-19 CAR construct LTG2737 contained the CAR sequence identical to the Anti-CD 22-19 CAR construct LTG2681, but without use of the Woodchuck Hepatitis Virus (WHP) Posttranscriptional Regulatory Element (WPRE) during its construction. 
     In another embodiment, several CAR T constructs were generated by linking the CAR antigen-binding domain in frame to CD8a hinge and transmembrane domains (constructs LTG2737, D0135, D0136, D0137, D0145, D0146, D0147, D0148, and D0149) as described in Example 3, infra. In other constructs a transmembrane domain sequence matching the co-stimulatory domain was utilized: CD28 for D139, D140, OX40 for D0137, D0147, D0148. The transmembrane domain was linked in frame to a co-stimulatory domain derived from 4-1BB (LTG2737), CD28 (D0135, D0139, D0140), ICOS (D0136, D0146, D0148, D0149), OX40 (D0137, D0145, D0147, D0148) or CD27 (D0138, D0149). All CAR molecules contained the CD3 zeta signaling domain (CD247, aa 52-163, Ref sequence ID: NP_000725.1). 
     In yet another embodiment, the endodomain of the CAR was comprised of two co-stimulatory domains, CD28 and 4-1BB, connected in tandem (D0140,  FIG. 6B ). In some embodiments, two distinct CAR molecules were co-expressed in the same T cell using a 2A ribosomal skip element for bicistronic expression (D146, D147, D148, D149,  FIG. 6C, 6D ). In this configuration, each CAR chain contained only one scFv, targeting either the CD19 or CD22 antigen, and both chains were co-expressed in each transduced T cell via transduction with a single lentiviral vector encoding the bicistronic sequence. 
     In yet other embodiments, on at least one of the CAR chains, no co-stimulatory domain was used, so that the CD3 activation domain was linked in frame directly to the transmembrane domain of one of the CAR chains expressed concurrently in the same cell (D0146, D0147,  FIG. 6C ). CAR constructs sequences were cloned into a third generation lentiviral plasmid backbone under the control of the human EF-1α promoter (Lentigen Technology Inc., Gaithersburg, Md.). 
     The surface expression of anti-CD22-19 CAR incorporating various co-stimulatory domains, is shown in  FIG. 7 . The expression level for each ScFv-containing CAR was determined by flow cytometric analysis of LV-transduced T cells from healthy donors using simultaneous staining for the two scFv CAR targeting domains i) CD22-his, followed anti-his-PE; ii) CD19 Fc recombinant protein, followed by anti Fc-A647. All anti-CD22-19 CAR were highly expressed in human primary T cells as compared to non-transduced T cell controls. CAR expression levels ranged from 71%-90% ( FIG. 7 ). 
     As shown in  FIGS. 9A-9D , high cytolytic activity of the anti-CD22-19 CAR was demonstrated: Human primary T cells were transduced with LV encoding CAR constructs LTG2737, D0135, D0136, D0137, D0138, D0139, D0140, D0145, D0146), then incubated for 18 hours with the Raji, 293T, 293TCD19 or 293TCD22 cell lines, stably transduced with firefly luciferase, for luminescence based in vitro killing assays. Effector to target (ET) ratios of 2.5:1, 5:1 or 10:1 were used, as noted in the legend to the right of each plot. Raji cells express CD19 and CD22 on their surface, while the negative controls, 293T do not. The 293TCD19 and 293TCD22 target lines were generated to stably express either the CD19 or CD22 target antigen, respectively, and were used to evaluate the capability of the dual-targeting CAR constructs with different co-stimulatory domains to accomplish target lysis when triggered by each single target antigen, CD19 or CD22, independently of the other antigen. 
     Raji cells were lysed effectively by all dual targeting CARs, but not by the untransduced T cells, UTD, a negative control ( FIG. 9A ). By comparison, all dual-targeting CAR constructs lysed the single-antigens lines 293TCD19 and 293TCD22, demonstrating the capability of these CAR constructs to trigger their anti-tumor lytic function when activated either by CD19 antigen alone, or by CD22 antigen alone ( FIGS. 9B and 9D , respectively). By contrast, none of the dual-targeting anti-CD22-19 CAR lysed the antigen-negative cell line 293T ( FIG. 9C ). Therefore, all anti-CD22-19 CAR were functional in tumor Raji line co-expressing the CD19 and CD22 antigens, and also in 293TCD19 and 293T CD22 lines expressing either CD19 or CD22 single antigen, and had no spontaneous killing activity against CD19-CD22-cell line 293T, underscoring the target specificity of these constructs. 
     The capacity of anti-CD22-19 CAR with various co-stimulatory domains for cytokine secretion was then evaluated ( FIG. 8 ). The CD19+CD22+ Raji tumor cells were co-incubated with the tandem anti-CD22-19 CAR T cells expressing constructs LTG2737, D0135, D0136, D0137, D0138, D0139, D0140, D0145, D0146, or negative control untransduced T cells (UTD) at effector to target ratio of 10:1 overnight, and culture supernatants were analyzed by ELISA for IFN gamma, TNF alpha, and IL-2 ( FIG. 8 ). All dual-targeting CARs strongly induced IL-2 and TNFα in response to tumor cells, whereas the negative control (untransduced, UTD) yielded no appreciable cytokine induction ( FIG. 8 ). Notably, the elaborated levels of IFN gamma, were strongly induced in all CAR 22-19, but were especially high for CAR constructs D0146, D0139, D0136, indicating that the strength of cytokine response of the anti-CD22-19 CAR may be modulated by the composition of co-stimulatory domains utilized in CAR design. Overall, the induced secretion profiles of IFN gamma, TNF alpha, and IL-2 demonstrated the high potency of all CAR 22-19 constructs. Importantly, anti-CD22-19 CAR produced little to no cytokine secretion in the absence of tumor cells (CAR T alone group), which further confirms CAR specificity, and indicates a lack of tonic signaling by the tandem anti-CD22-19 CAR with various co-stimulatory domains. 
     Without being intended to limit to any particular mechanism of action, it is believed that possible reasons for the enhanced therapeutic function associated with the exemplary tandem CD22 and CD19 targeting CARs of the invention include, for example, and not by way of limitation, a) improved lateral movement within the plasma membrane allowing for more efficient signal transduction, b) superior location within plasma membrane microdomains, such as lipid rafts, and greater ability to interact with transmembrane signaling cascades associated with T cell activation, c) superior location within the plasma membrane by preferential movement away from dampening or down-modulatory interactions, such as less proximity to or interaction with phosphatases such as CD45, and d) superior assembly into T cell receptor signaling complexes (i.e. the immune synapse), or e) superior ability to engage with tumor antigen due to two distinct targeting domains present in each CAR molecule, or any combination thereof. 
     While the disclosure has been illustrated with an exemplary extracellular CD19/CD22 variable heavy chain only and ScFv antigen binding domains, other nucleotide and/or amino acid variants within the CD19/CD22 variable heavy chain only and ScFv antigen binding domains may be used to derive the CD19/CD22 antigen binding domains for use in the CARs described herein. 
     Depending on the desired antigen to be targeted, the CAR can be additionally engineered to include the appropriate antigen binding domain that is specific to the desired antigen target. For example, if CD19/CD22 is the desired antigen that is to be targeted, an antibody for CD19/CD22 can be used as the antigen bind domain incorporation into the CAR. 
     In one exemplary embodiment, the antigen binding domain portion of the CAR additionally targets CD33. Preferably, the antigen binding domain in the CAR is anti-CD33 ScFv, wherein the nucleic acid sequence of the anti-CD33 ScFv comprises the sequence set forth in SEQ ID NO: 46. In one embodiment, the anti-CD33 ScFv comprises the nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 46. In another embodiment, the anti-CD19/CD22 ScFv portion of the CAR comprises the amino acid sequence set forth in SEQ ID NO: 47. 
     In one exemplary embodiment, the antigen binding domain portion of the CAR additionally targets mesothelin. Preferably, the antigen binding domain in the CAR is anti-mesothelin ScFv, wherein the nucleic acid sequence of the anti-mesothelin ScFv comprises the sequence set forth in SEQ ID NO: 48. In one embodiment, the anti-mesothelin ScFv comprises the nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 48. In another embodiment, the anti-mesothelin ScFv portion of the CAR comprises the amino acid sequence set forth in SEQ ID NO: 49. 
     In one aspect of the present invention, there is provided a CAR capable of binding to a non-TSA or non-TAA including, for example and not by way of limitation, an antigen derived from Retroviridae (e.g. human immunodeficiency viruses such as HIV-1 and HIV-LP), Picornaviridae (e.g. poliovirus, hepatitis A virus, enterovirus, human coxsackievirus, rhinovirus, and echovirus), rubella virus, coronavirus, vesicular stomatitis virus, rabies virus, ebola virus, parainfluenza virus, mumps virus, measles virus, respiratory syncytial virus, influenza virus, hepatitis B virus, parvovirus, Adenoviridae, Herpesviridae [e.g. type 1 and type 2 herpes simplex virus (HSV), varicella-zoster virus, cytomegalovirus (CMV), and herpes virus], Poxviridae (e.g. smallpox virus, vaccinia virus, and pox virus), or hepatitis C virus, or any combination thereof. 
     In another aspect of the present invention, there is provided a CAR capable of binding to an antigen derived from a bacterial strain of Staphylococci,  Streptococcus, Escherichia coli, Pseudomonas , or  Salmonella . Particularly, there is provided a CAR capable of binding to an antigen derived from an infectious bacterium, for example,  Helicobacter pyloris, Legionella  pneumophilia, a bacterial strain of Mycobacteria sps. (e.g.  M. tuberculosis, M. avium, M. intracellulare, M. kansaii , or  M. gordonea ),  Staphylococcus aureus, Neisseria gonorrhoeae, Neisseria meningitides, Listeria monocytogenes, Streptococcus pyogenes , Group A  Streptococcus , Group B  Streptococcus  ( Streptococcus agalactiae ),  Streptococcus pneumoniae , or  Clostridium tetani , or a combination thereof 
     2. Transmembrane Domain 
     With respect to the transmembrane domain, the CAR comprises one or more transmembrane domains fused to the extracellular CD19/CD22 antigen binding domain of the CAR. 
     The transmembrane domain may be derived either from a natural or from a synthetic source. Where the source is natural, the domain may be derived from any membrane-bound or transmembrane protein. 
     Transmembrane regions of particular use in the CARs described herein may be derived from (i.e. comprise at least the transmembrane region(s) of) the alpha, beta or zeta chain of the T-cell receptor, CD28, CD3 epsilon, CD45, CD4, CD5, CD8, CD9, CD16, CD22, mesothelin, CD33, CD37, CD64, CD80, CD83, CD86, CD134, CD137, CD154, TNFRSF16, or TNFRSF19. Alternatively the transmembrane domain may be synthetic, in which case it will comprise predominantly hydrophobic residues such as leucine and valine. Preferably a triplet of phenylalanine, tryptophan and valine will be found at each end of a synthetic transmembrane domain. Optionally, a short oligo- or polypeptide linker, preferably between 2 and 10 amino acids in length may form the linkage between the transmembrane domain and the cytoplasmic signaling domain of the CAR. A glycine-serine doublet provides a particularly suitable linker. 
     In one embodiment, the transmembrane domain that naturally is associated with one of the domains in the CAR is used in addition to the transmembrane domains described supra. 
     In some instances, the transmembrane domain can be selected or by amino acid substitution to avoid binding of such domains to the transmembrane domains of the same or different surface membrane proteins to minimize interactions with other members of the receptor complex. 
     In one embodiment, the transmembrane domain in the CAR of the invention is the CD8 transmembrane domain. In one embodiment, the CD8 transmembrane domain comprises the nucleic acid sequence of SEQ ID NO: 35. In one embodiment, the CD8 transmembrane domain comprises the nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 36. In another embodiment, the CD8 transmembrane domain comprises the amino acid sequence of SEQ ID NO: 36. 
     In one embodiment, the encoded transmembrane domain comprises an amino acid sequence having at least one, two or three modifications (e.g., substitutions) but not more than 20, 10 or 5 modifications (e.g., substitutions) of an amino acid sequence of SEQ ID NO: 36, or a sequence with 95-99% identity to an amino acid sequence of SEQ ID NO: 36. 
     In some instances, the transmembrane domain of the CAR comprises the CD8.alpha.hinge domain. In one embodiment, the CD8 hinge domain comprises the nucleic acid sequence of SEQ ID NO: 37. In one embodiment, the CD8 hinge domain comprises the nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 38. In another embodiment, the CD8 hinge domain comprises the amino acid sequence of SEQ ID NO: 38, or a sequence with 95-99% identify thereof. 
     In one embodiment, an isolated nucleic acid molecule is provided wherein the encoded linker domain is derived from the extracellular domain of CD8, and is linked to the transmembrane CD8 domain, the transmembrane CD28 domain, or a combination thereof 
     3. Spacer Domain 
     In the CAR, a spacer domain can be arranged between the extracellular domain and the transmembrane domain, or between the intracellular domain and the transmembrane domain. The spacer domain means any oligopeptide or polypeptide that serves to link the transmembrane domain with the extracellular domain and/or the transmembrane domain with the intracellular domain. The spacer domain comprises up to 300 amino acids, preferably 10 to 100 amino acids, and most preferably 25 to 50 amino acids. 
     In several embodiments, the linker can include a spacer element, which, when present, increases the size of the linker such that the distance between the effector molecule or the detectable marker and the antibody or antigen binding fragment is increased. Exemplary spacers are known to the person of ordinary skill, and include those listed in U.S. Pat. Nos. 7,964,566, 7,498,298, 6,884,869, 6,323,315, 6,239,104, 6,034,065, 5,780,588, 5,665,860, 5,663,149, 5,635,483, 5,599,902, 5,554,725, 5,530,097, 5,521,284, 5,504,191, 5,410,024, 5,138,036, 5,076,973, 4,986,988, 4,978,744, 4,879,278, 4,816,444, and 4,486,414, as well as U.S. Pat. Pub. Nos. 20110212088 and 20110070248, each of which is incorporated by reference herein in its entirety. 
     The spacer domain preferably has a sequence that promotes binding of a CAR with an antigen and enhances signaling into a cell. Examples of an amino acid that is expected to promote the binding include cysteine, a charged amino acid, and serine and threonine in a potential glycosylation site, and these amino acids can be used as an amino acid constituting the spacer domain. 
     As the spacer domain, the entire or a part of amino acid numbers 137-206 (SEQ ID NO: 39) which is a hinge region of CD8.alpha. (NCBI RefSeq: NP.sub.-001759.3), amino acid numbers 135 to 195 of CD8.beta. (GenBank: AAA35664.1), amino acid numbers 315 to 396 of CD4 (NCBI RefSeq: NP.sub.-000607.1), or amino acid numbers 137 to 152 of CD28 (NCBI RefSeq: NP.sub.-006130.1) can be used. Also, as the spacer domain, a part of a constant region of an antibody H chain or L chain can be used. Further, the spacer domain may be an artificially synthesized sequence. 
     Further, in the CAR, a signal peptide sequence can be linked to the N-terminus. The signal peptide sequence exists at the N-terminus of many secretory proteins and membrane proteins, and has a length of 15 to 30 amino acids. Since many of the protein molecules mentioned above as the intracellular domain have signal peptide sequences, the signal peptides can be used as a signal peptide for the CAR. In one embodiment, the signal peptide comprises the amino acid sequence shown in SEQ ID NO: 12. 
     4. Intracellular Domain 
     The cytoplasmic domain or otherwise the intracellular signaling domain of the CAR is responsible for activation of at least one of the normal effector functions of the immune cell in which the CAR has been placed in. The term “effector function” refers to a specialized function of a cell. Effector function of a T cell, for example, may be cytolytic activity or helper activity including the secretion of cytokines. Thus the term “intracellular signaling domain” refers to the portion of a protein which transduces the effector function signal and directs the cell to perform a specialized function. While usually the entire intracellular signaling domain can be employed, in many cases it is not necessary to use the entire chain. To the extent that a truncated portion of the intracellular signaling domain is used, such truncated portion may be used in place of the intact chain as long as it transduces the effector function signal. The term intracellular signaling domain is thus meant to include any truncated portion of the intracellular signaling domain sufficient to transduce the effector function signal. 
     Preferred examples of intracellular signaling domains for use in the CAR include the cytoplasmic sequences of the T cell receptor (TCR) and co-receptors that act in concert to initiate signal transduction following antigen receptor engagement, as well as any derivative or variant of these sequences and any synthetic sequence that has the same functional capability. 
     It is known that signals generated through the TCR alone are insufficient for full activation of the T cell and that a secondary or co-stimulatory signal is also required. Thus, T cell activation can be said to be mediated by two distinct classes of cytoplasmic signaling sequence: those that initiate antigen-dependent primary activation through the TCR (primary cytoplasmic signaling sequences) and those that act in an antigen-independent manner to provide a secondary or co-stimulatory signal (secondary cytoplasmic signaling sequences). 
     Primary cytoplasmic signaling sequences regulate primary activation of the TCR complex either in a stimulatory way, or in an inhibitory way. Primary cytoplasmic signaling sequences that act in a stimulatory manner may contain signaling motifs which are known as immunoreceptor tyrosine-based activation motifs or ITAMs. 
     Examples of ITAM containing primary cytoplasmic signaling sequences that are of particular use in the CARs disclosed herein include those derived from TCR zeta (CD3 Zeta), FcR gamma, FcR beta, CD3 gamma, CD3 delta, CD3 epsilon, CD5, CD22, CD79a, CD79b, and CD66d. Specific, non-limiting examples, of the ITAM include peptides having sequences of amino acid numbers 51 to 164 of CD3 zeta. (NCBI RefSeq: NP.sub.-932170.1), amino acid numbers 45 to 86 of Fc epsilon RI gamma. (NCBI RefSeq: NP.sub.-004097.1), amino acid numbers 201 to 244 of Fc epsilon RI beta. (NCBI RefSeq: NP.sub.-000130.1), amino acid numbers 139 to 182 of CD3 gamma. (NCBI RefSeq: NP.sub.-000064.1), amino acid numbers 128 to 171 of CD3 delta. (NCBI RefSeq: NP.sub.-000723.1), amino acid numbers 153 to 207 of CD3.epsilon. (NCBI RefSeq: NP.sub.-000724.1), amino acid numbers 402 to 495 of CD5 (NCBI RefSeq: NP.sub.-055022.2), amino acid numbers 707 to 847 of 0022 (NCBI RefSeq: NP.sub.-001762.2), amino acid numbers 166 to 226 of CD79a (NCBI RefSeq: NP.sub.-001774.1), amino acid numbers 182 to 229 of CD79b (NCBI RefSeq: NP.sub.-000617.1), and amino acid numbers 177 to 252 of CD66d (NCBI RefSeq: NP.sub.-001806.2), and their variants having the same function as these peptides have. The amino acid number based on amino acid sequence information of NCBI RefSeq ID or GenBank described herein is numbered based on the full length of the precursor (comprising a signal peptide sequence etc.) of each protein. In one embodiment, the cytoplasmic signaling molecule in the CAR comprises a cytoplasmic signaling sequence derived from CD3 zeta. 
     In a preferred embodiment, the intracellular domain of the CAR can be designed to comprise the CD3-zeta signaling domain by itself or combined with any other desired cytoplasmic domain(s) useful in the context of the CAR. For example, the intracellular domain of the CAR can comprise a CD3 zeta chain portion and a costimulatory signaling region. The costimulatory signaling region refers to a portion of the CAR comprising the intracellular domain of a costimulatory molecule. A costimulatory molecule is a cell surface molecule other than an antigen receptor or their ligands that is required for an efficient response of lymphocytes to an antigen. Examples of such costimulatory molecules include CD27, CD28, 4-1BB (CD137), OX40, CD30, CD40, PD-1, ICOS, lymphocyte function-associated antigen-1 (LFA-1), CD2, CD7, LIGHT, NKG2C, B7-H3, and a ligand that specifically binds with CD83, and the like. Specific, non-limiting examples, of such costimulatory molecules include peptides having sequences of amino acid numbers 236 to 351 of CD2 (NCBI RefSeq: NP.sub.-001758.2), amino acid numbers 421 to 458 of CD4 (NCBI RefSeq: NP.sub.-000607.1), amino acid numbers 402 to 495 of CD5 (NCBI RefSeq: NP.sub.-055022.2), amino acid numbers 207 to 235 of CD8 alpha. (NCBI RefSeq: NP.sub.-001759.3), amino acid numbers 196 to 210 of CD83 (GenBank: AAA35664.1), amino acid numbers 181 to 220 of CD28 (NCBI RefSeq: NP.sub.-006130.1), amino acid numbers 214 to 255 of CD137 (4-1BB, NCBI RefSeq: NP.sub.-001552.2), amino acid numbers 241 to 277 of CD134 (OX40, NCBI RefSeq: NP.sub.-003318.1), and amino acid numbers 166 to 199 of ICOS (NCBI RefSeq: NP.sub.-036224.1), and their variants having the same function as these peptides have. Thus, while the disclosure herein is exemplified primarily with 4-1BB as the co-stimulatory signaling element, other costimulatory elements are within the scope of the disclosure. 
     The cytoplasmic signaling sequences within the cytoplasmic signaling portion of the CAR may be linked to each other in a random or specified order. Optionally, a short oligo- or polypeptide linker, preferably between 2 and 10 amino acids in length may form the linkage. A glycine-serine doublet provides a particularly suitable linker. 
     In one embodiment, the intracellular domain is designed to comprise the signaling domain of CD3-zeta and the signaling domain of CD28. In another embodiment, the intracellular domain is designed to comprise the signaling domain of CD3-zeta and the signaling domain of 4-1BB. In yet another embodiment, the intracellular domain is designed to comprise the signaling domain of CD3-zeta and the signaling domain of CD28 and 4-1BB. 
     In one embodiment, the intracellular domain in the CAR is designed to comprise the signaling domain of 4-1BB and the signaling domain of CD3-zeta, wherein the signaling domain of 4-1BB comprises the nucleic acid sequence set forth in SEQ ID NO: 40 and the signaling domain of CD3-zeta comprises the nucleic acid sequence set forth in SEQ ID NO: 42. 
     In one embodiment, the intracellular domain in the CAR is designed to comprise the signaling domain of 4-1BB and the signaling domain of CD3-zeta, wherein the signaling domain of 4-1BB comprises the nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 41 and the signaling domain of CD3-zeta comprises the nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 43. 
     In one embodiment, the intracellular domain in the CAR is designed to comprise the signaling domain of 4-1BB and the signaling domain of CD3-zeta, wherein the signaling domain of 4-1BB comprises the amino acid sequence set forth in SEQ ID NO: 41 and the signaling domain of CD3-zeta comprises the amino acid sequence set forth in SEQ ID NO: 43. 
     5. Additional Description of CARs 
     Also expressly included within the scope of the invention are functional portions of the CARs disclosed herein. The term “functional portion” when used in reference to a CAR refers to any part or fragment of one or more of the CARs disclosed herein, which part or fragment retains the biological activity of the CAR of which it is a part (the parent CAR). Functional portions encompass, for example, those parts of a CAR that retain the ability to recognize target cells, or detect, treat, or prevent a disease, to a similar extent, the same extent, or to a higher extent, as the parent CAR. In reference to the parent CAR, the functional portion can comprise, for instance, about 10%, 25%, 30%, 50%, 68%, 80%, 90%, 95%, or more, of the parent CAR. 
     The functional portion can comprise additional amino acids at the amino or carboxy terminus of the portion, or at both termini, which additional amino acids are not found in the amino acid sequence of the parent CAR. Desirably, the additional amino acids do not interfere with the biological function of the functional portion, e.g., recognize target cells, detect cancer, treat or prevent cancer, etc. More desirably, the additional amino acids enhance the biological activity, as compared to the biological activity of the parent CAR. 
     Included in the scope of the disclosure are functional variants of the CARs disclosed herein. The term “functional variant” as used herein refers to a CAR, polypeptide, or protein having substantial or significant sequence identity or similarity to a parent CAR, which functional variant retains the biological activity of the CAR of which it is a variant. Functional variants encompass, for example, those variants of the CAR described herein (the parent CAR) that retain the ability to recognize target cells to a similar extent, the same extent, or to a higher extent, as the parent CAR. In reference to the parent CAR, the functional variant can, for instance, be at least about 30%, 50%, 75%, 80%, 90%, 98% or more identical in amino acid sequence to the parent CAR. 
     A functional variant can, for example, comprise the amino acid sequence of the parent CAR with at least one conservative amino acid substitution. Alternatively or additionally, the functional variants can comprise the amino acid sequence of the parent CAR with at least one non-conservative amino acid substitution. In this case, it is preferable for the non-conservative amino acid substitution to not interfere with or inhibit the biological activity of the functional variant. The non-conservative amino acid substitution may enhance the biological activity of the functional variant, such that the biological activity of the functional variant is increased as compared to the parent CAR. 
     Amino acid substitutions of the CARs are preferably conservative amino acid substitutions. Conservative amino acid substitutions are known in the art, and include amino acid substitutions in which one amino acid having certain physical and/or chemical properties is exchanged for another amino acid that has the same or similar chemical or physical properties. For instance, the conservative amino acid substitution can be an acidic/negatively charged polar amino acid substituted for another acidic/negatively charged polar amino acid (e.g., Asp or Glu), an amino acid with a nonpolar side chain substituted for another amino acid with a nonpolar side chain (e.g., Ala, Gly, Val, He, Leu, Met, Phe, Pro, Trp, Cys, Val, etc.), a basic/positively charged polar amino acid substituted for another basic/positively charged polar amino acid (e.g. Lys, His, Arg, etc.), an uncharged amino acid with a polar side chain substituted for another uncharged amino acid with a polar side chain (e.g., Asn, Gin, Ser, Thr, Tyr, etc.), an amino acid with a beta-branched side-chain substituted for another amino acid with a beta-branched side-chain (e.g., He, Thr, and Val), an amino acid with an aromatic side-chain substituted for another amino acid with an aromatic side chain (e.g., His, Phe, Trp, and Tyr), etc. 
     The CAR can consist essentially of the specified amino acid sequence or sequences described herein, such that other components, e.g., other amino acids, do not materially change the biological activity of the functional variant. 
     The CARs (including functional portions and functional variants) can be of any length, i.e., can comprise any number of amino acids, provided that the CARs (or functional portions or functional variants thereof) retain their biological activity, e.g., the ability to specifically bind to antigen, detect diseased cells in a mammal, or treat or prevent disease in a mammal, etc. For example, the CAR can be about 50 to about 5000 amino acids long, such as 50, 70, 75, 100, 125, 150, 175, 200, 300, 400, 500, 600, 700, 800, 900, 1000 or more amino acids in length. 
     The CARs (including functional portions and functional variants of the invention) can comprise synthetic amino acids in place of one or more naturally-occurring amino acids. Such synthetic amino acids are known in the art, and include, for example, aminocyclohexane carboxylic acid, norleucine, -amino n-decanoic acid, homoserine, S-acetylaminomethyl-cysteine, trans-3- and trans-4-hydroxyproline, 4-aminophenylalanine, 4-nitrophenylalanine, 4-chlorophenylalanine, 4-carboxyphenylalanine, β-phenylserine β-hydroxyphenylalanine, phenylglycine, a-naphthylalanine, cyclohexylalanine, cyclohexylglycine, indoline-2-carboxylic acid, 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, aminomalonic acid, aminomalonic acid monoamide, N′-benzyl-N′-methyl-lysine, N′,N′-dibenzyl-lysine, 6-hydroxylysine, ornithine, -aminocyclopentane carboxylic acid, a-aminocyclohexane carboxylic acid, a-aminocycloheptane carboxylic acid, a-(2-amino-2-norbornane)-carboxylic acid, γ-diaminobutyric acid, β-diaminopropionic acid, homophenylalanine, and a-tert-butylglycine. 
     The CARs (including functional portions and functional variants) can be glycosylated, amidated, carboxylated, phosphorylated, esterified, N-acylated, cyclized via, e.g., a disulfide bridge, or converted into an acid addition salt and/or optionally dimerized or polymerized, or conjugated. 
     The CARs (including functional portions and functional variants thereof) can be obtained by methods known in the art. The CARs may be made by any suitable method of making polypeptides or proteins. Suitable methods of de novo synthesizing polypeptides and proteins are described in references, such as Chan et al., Fmoc Solid Phase Peptide Synthesis, Oxford University Press, Oxford, United Kingdom, 2000; Peptide and Protein Drug Analysis, ed. Reid, R., Marcel Dekker, Inc., 2000; Epitope Mapping, ed. Westwood et al., Oxford University Press, Oxford, United Kingdom, 2001; and U.S. Pat. No. 5,449,752. Also, polypeptides and proteins can be recombinantly produced using the nucleic acids described herein using standard recombinant methods. See, for instance, Sambrook et al., Molecular Cloning: A Laboratory Manual, 3rd ed., Cold Spring Harbor Press, Cold Spring Harbor, N.Y. 2001; and Ausubel et al., Current Protocols in Molecular Biology, Greene Publishing Associates and John Wiley &amp; Sons, NY, 1994. Further, some of the CARS (including functional portions and functional variants thereof) can be isolated and/or purified from a source, such as a plant, a bacterium, an insect, a mammal, e.g., a rat, a human, etc. Methods of isolation and purification are well-known in the art. Alternatively, the CARs described herein (including functional portions and functional variants thereof) can be commercially synthesized by companies. In this respect, the CARS can be synthetic, recombinant, isolated, and/or purified. 
     B. Antibodies and Antigen Binding Fragments 
     One embodiment further provides a CAR, a T cell expressing a CAR, an antibody, or antigen binding domain or portion thereof, which specifically binds to one or more of the antigens disclosed herein. As used herein, a “T cell expressing a CAR,” or a “CAR T cell” means a T cell expressing a CAR, and has antigen specificity determined by, for example, the antibody-derived targeting domain of the CAR. 
     As used herein, and “antigen binding domain” can include an antibody and antigen binding fragments thereof. The term “antibody” is used herein in the broadest sense and encompasses various antibody structures, including but not limited to monoclonal antibodies, polyclonal antibodies, multi-specific antibodies (e.g., bispecific antibodies), and antigen binding fragments thereof, so long as they exhibit the desired antigen-binding activity. Non-limiting examples of antibodies include, for example, intact immunoglobulins and variants and fragments thereof known in the art that retain binding affinity for the antigen. 
     A “monoclonal antibody” is an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts. Monoclonal antibodies are highly specific, being directed against a single antigenic epitope. The modifier “monoclonal” indicates the character of the antibody as being obtained from a substantially homogeneous population of antibodies, and is not to be construed as requiring production of the antibody by any particular method. In some examples, a monoclonal antibody is an antibody produced by a single clone of B lymphocytes or by a cell into which nucleic acid encoding the light and heavy variable regions of the antibody of a single antibody (or an antigen binding fragment thereof) have been transfected, or a progeny thereof. In some examples monoclonal antibodies are isolated from a subject. Monoclonal antibodies can have conservative amino acid substitutions which have substantially no effect on antigen binding or other immunoglobulin functions. Exemplary methods of production of monoclonal antibodies are known, for example, see Harlow &amp; Lane, Antibodies, A Laboratory Manual, 2nd ed. Cold Spring Harbor Publications, New York (2013). 
     Typically, an immunoglobulin has heavy (H) chains and light (L) chains interconnected by disulfide bonds. Immunoglobulin genes include the kappa, lambda, alpha, gamma, delta, epsilon and mu constant region genes, as well as the myriad immunoglobulin variable domain genes. There are two types of light chain, lambda (λ) and kappa (κ). There are five main heavy chain classes (or isotypes) which determine the functional activity of an antibody molecule: IgM, IgD, IgG, IgA and IgE. 
     Each heavy and light chain contains a constant region (or constant domain) and a variable region (or variable domain; see, e.g., Kindt et al. Kuby Immunology, 6 th  ed., W.H. Freeman and Co., page 91 (2007).) In several embodiments, the heavy and the light chain variable regions combine to specifically bind the antigen. In additional embodiments, only the heavy chain variable region is required. For example, naturally occurring camelid antibodies consisting of a heavy chain only are functional and stable in the absence of light chain (see, e.g., Hamers-Casterman et al., Nature, 363:446-448, 1993; Sheriff et al., Nat. Struct. Biol., 3:733-736, 1996). References to “VH” or “VH” refer to the variable region of an antibody heavy chain, including that of an antigen binding fragment, such as Fv, ScFv, dsFv or Fab. References to “VL” or “VL” refer to the variable domain of an antibody light chain, including that of an Fv, ScFv, dsFv or Fab. 
     Light and heavy chain variable regions contain a “framework” region interrupted by three hypervariable regions, also called “complementarity-determining regions” or “CDRs” (see, e.g., Kabat et al., Sequences of Proteins of Immunological Interest, U.S. Department of Health and Human Services, 1991). The sequences of the framework regions of different light or heavy chains are relatively conserved within a species. The framework region of an antibody, that is the combined framework regions of the constituent light and heavy chains, serves to position and align the CDRs in three-dimensional space. 
     The CDRs are primarily responsible for binding to an epitope of an antigen. The amino acid sequence boundaries of a given CDR can be readily determined using any of a number of well-known schemes, including those described by Kabat et al. (“Sequences of Proteins of Immunological Interest,” 5 th  Ed. Public Health Service, National Institutes of Health, Bethesda, Md., 1991; “Kabat” numbering scheme), Al-Lazikani et al., (JMB 273,927-948, 1997; “Chothia” numbering scheme), and Lefranc et al. (“IMGT unique numbering for immunoglobulin and T cell receptor variable domains and Ig superfamily V-like domains,” Dev. Comp. Immunol., 27:55-77, 2003; “IMGT” numbering scheme). The CDRs of each chain are typically referred to as CDR1, CDR2, and CDR3 (from the N-terminus to C-terminus), and are also typically identified by the chain in which the particular CDR is located. Thus, a VH CDR3 is the CDR3 from the variable domain of the heavy chain of the antibody in which it is found, whereas a VL CDR1 is the CDR1 from the variable domain of the light chain of the antibody in which it is found. Light chain CDRs are sometimes referred to as LCDR1, LCDR2, and LCDR3. Heavy chain CDRs are sometimes referred to as LCDR1, LCDR2, and LCDR3. 
     An “antigen binding fragment” is a portion of a full length antibody that retains the ability to specifically recognize the cognate antigen, as well as various combinations of such portions. Non-limiting examples of antigen binding fragments include Fv, Fab, Fab′, Fab′-SH, F(ab′)2; diabodies; linear antibodies; single-chain antibody molecules (e.g. ScFv); and multi-specific antibodies formed from antibody fragments. Antibody fragments include antigen binding fragments either produced by the modification of whole antibodies or those synthesized de novo using recombinant DNA methodologies (see, e.g., Kontermann and Dubel (Ed), Antibody Engineering, Vols. 1-2, 2nd Ed., Springer Press, 2010). 
     A single-chain antibody (ScFv) is a genetically engineered molecule containing the VH and VL domains of one or more antibody(ies) linked by a suitable polypeptide linker as a genetically fused single chain molecule (see, for example, Bird et al., Science, 242:423 426, 1988; Huston et al., Proc. Natl. Acad. Sci., 85:5879 5883, 1988; Ahmad et al., Clin. Dev. Immunol., 2012, doi:10.1155/2012/980250; Marbry, IDrugs, 13:543-549, 2010). The intramolecular orientation of the VH-domain and the VL-domain in a ScFv, is typically not decisive for ScFvs. Thus, ScFvs with both possible arrangements (VH-domain-linker domain-VL-domain; VL-domain-linker domain-VH-domain) may be used. 
     In a dsFv, the heavy and light chain variable chains have been mutated to introduce a disulfide bond to stabilize the association of the chains. Diabodies also are included, which are bivalent, bispecific antibodies in which VH and VL domains are expressed on a single polypeptide chain, but using a linker that is too short to allow for pairing between the two domains on the same chain, thereby forcing the domains to pair with complementary domains of another chain and creating two antigen binding sites (see, for example, Holliger et al., Proc. Natl. Acad. Sci., 90:6444 6448, 1993; Poljak et al., Structure, 2:1121 1123, 1994). 
     Antibodies also include genetically engineered forms such as chimeric antibodies (such as humanized murine antibodies) and heteroconjugate antibodies (such as bispecific antibodies). See also, Pierce Catalog and Handbook, 1994-1995 (Pierce Chemical Co., Rockford, Ill.); Kuby, J., Immunology, 3rd Ed., W.H. Freeman &amp; Co., New York, 1997. 
     Non-naturally occurring antibodies can be constructed using solid phase peptide synthesis, can be produced recombinantly, or can be obtained, for example, by screening combinatorial libraries consisting of variable heavy chains and variable light chains as described by Huse et al., Science 246:1275-1281 (1989), which is incorporated herein by reference. These and other methods of making, for example, chimeric, humanized, CDR-grafted, single chain, and bifunctional antibodies, are well known to those skilled in the art (Winter and Harris, Immunol. Today 14:243-246 (1993); Ward et al., Nature 341:544-546 (1989); Harlow and Lane, supra, 1988; Hilyard et al., Protein Engineering: A practical approach (IRL Press 1992); Borrabeck, Antibody Engineering, 2d ed. (Oxford University Press 1995); each of which is incorporated herein by reference). 
     An “antibody that binds to the same epitope” as a reference antibody refers to an antibody that blocks binding of the reference antibody to its antigen in a competition assay by 50% or more, and conversely, the reference antibody blocks binding of the antibody to its antigen in a competition assay by 50% or more. Antibody competition assays are known, and an exemplary competition assay is provided herein. 
     A “humanized” antibody or antigen binding fragment includes a human framework region and one or more CDRs from a non-human (such as a mouse, rat, or synthetic) antibody or antigen binding fragment. The non-human antibody or antigen binding fragment providing the CDRs is termed a “donor,” and the human antibody or antigen binding fragment providing the framework is termed an “acceptor.” In one embodiment, all the CDRs are from the donor immunoglobulin in a humanized immunoglobulin. Constant regions need not be present, but if they are, they can be substantially identical to human immunoglobulin constant regions, such as at least about 85-90%, such as about 95% or more identical. Hence, all parts of a humanized antibody or antigen binding fragment, except possibly the CDRs, are substantially identical to corresponding parts of natural human antibody sequences. 
     A “chimeric antibody” is an antibody which includes sequences derived from two different antibodies, which typically are of different species. In some examples, a chimeric antibody includes one or more CDRs and/or framework regions from one human antibody and CDRs and/or framework regions from another human antibody. 
     A “fully human antibody” or “human antibody” is an antibody which includes sequences from (or derived from) the human genome, and does not include sequence from another species. In some embodiments, a human antibody includes CDRs, framework regions, and (if present) an Fc region from (or derived from) the human genome. Human antibodies can be identified and isolated using technologies for creating antibodies based on sequences derived from the human genome, for example by phage display or using transgenic animals (see, e.g., Barbas et al. Phage display: A Laboratory Manuel. 1st Ed. New York: Cold Spring Harbor Laboratory Press, 2004. Print; Lonberg, Nat. Biotech., 23: 1117-1125, 2005; Lonenberg, Curr. Opin. Immunol., 20:450-459, 2008). 
     An antibody may have one or more binding sites. If there is more than one binding site, the binding sites may be identical to one another or may be different. For instance, a naturally-occurring immunoglobulin has two identical binding sites, a single-chain antibody or Fab fragment has one binding site, while a bispecific or bifunctional antibody has two different binding sites. 
     Methods of testing antibodies for the ability to bind to any functional portion of the CAR are known in the art and include any antibody-antigen binding assay, such as, for example, radioimmunoassay (RIA), ELISA, Western blot, immunoprecipitation, and competitive inhibition assays (see, e.g., Janeway et al., infra, U.S. Patent Application Publication No. 2002/0197266 A1, and U.S. Pat. No. 7,338,929). 
     Also, a CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof, can be modified to comprise a detectable label, such as, for instance, a radioisotope, a fluorophore (e.g., fluorescein isothiocyanate (FITC), phycoerythrin (PE)), an enzyme (e.g., alkaline phosphatase, horseradish peroxidase), and element particles (e.g., gold particles). 
     C. Conjugates 
     A CAR, a T cell expressing a CAR, or monoclonal antibodies, or antigen binding fragments thereof, specific for one or more of the antigens disclosed herein, can be conjugated to an agent, such as an effector molecule or detectable marker, using any number of means known to those of skill in the art. Both covalent and noncovalent attachment means may be used. Conjugates include, but are not limited to, molecules in which there is a covalent linkage of an effector molecule or a detectable marker to an antibody or antigen binding fragment that specifically binds one or more of the antigens disclosed herein. One of skill in the art will appreciate that various effector molecules and detectable markers can be used, including (but not limited to) chemotherapeutic agents, anti-angiogenic agents, toxins, radioactive agents such as  125 I,  32 P,  14 C,  3 H and  35 S and other labels, target moieties and ligands, etc. 
     The choice of a particular effector molecule or detectable marker depends on the particular target molecule or cell, and the desired biological effect. Thus, for example, the effector molecule can be a cytotoxin that is used to bring about the death of a particular target cell (such as a tumor cell). 
     The procedure for attaching an effector molecule or detectable marker to an antibody or antigen binding fragment varies according to the chemical structure of the effector. Polypeptides typically contain a variety of functional groups; such as carboxylic acid (COOH), free amine (—NH 2 ) or sulfhydryl (—SH) groups, which are available for reaction with a suitable functional group on an antibody to result in the binding of the effector molecule or detectable marker. Alternatively, the antibody or antigen binding fragment is derivatized to expose or attach additional reactive functional groups. The derivatization may involve attachment of any of a number of known linker molecules such as those available from Pierce Chemical Company, Rockford, Ill. The linker can be any molecule used to join the antibody or antigen binding fragment to the effector molecule or detectable marker. The linker is capable of forming covalent bonds to both the antibody or antigen binding fragment and to the effector molecule or detectable marker. Suitable linkers are well known to those of skill in the art and include, but are not limited to, straight or branched-chain carbon linkers, heterocyclic carbon linkers, or peptide linkers. Where the antibody or antigen binding fragment and the effector molecule or detectable marker are polypeptides, the linkers may be joined to the constituent amino acids through their side groups (such as through a disulfide linkage to cysteine) or to the alpha carbon amino and carboxyl groups of the terminal amino acids. 
     In several embodiments, the linker can include a spacer element, which, when present, increases the size of the linker such that the distance between the effector molecule or the detectable marker and the antibody or antigen binding fragment is increased. Exemplary spacers are known to the person of ordinary skill, and include those listed in U.S. Pat. Nos. 7,964,566, 7,498,298, 6,884,869, 6,323,315, 6,239,104, 6,034,065, 5,780,588, 5,665,860, 5,663,149, 5,635,483, 5,599,902, 5,554,725, 5,530,097, 5,521,284, 5,504,191, 5,410,024, 5,138,036, 5,076,973, 4,986,988, 4,978,744, 4,879,278, 4,816,444, and 4,486,414, as well as U.S. Pat. Pub. Nos. 20110212088 and 20110070248, each of which is incorporated by reference herein in its entirety. 
     In some embodiments, the linker is cleavable under intracellular conditions, such that cleavage of the linker releases the effector molecule or detectable marker from the antibody or antigen binding fragment in the intracellular environment. In yet other embodiments, the linker is not cleavable and the effector molecule or detectable marker is released, for example, by antibody degradation. In some embodiments, the linker is cleavable by a cleaving agent that is present in the intracellular environment (for example, within a lysosome or endosome or caveolea). The linker can be, for example, a peptide linker that is cleaved by an intracellular peptidase or protease enzyme, including, but not limited to, a lysosomal or endosomal protease. In some embodiments, the peptide linker is at least two amino acids long or at least three amino acids long. However, the linker can be 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15 amino acids long, such as 1-2, 1-3, 2-5, 3-10, 3-15, 1-5, 1-10, 1-15 amino acids long. Proteases can include cathepsins B and D and plasmin, all of which are known to hydrolyze dipeptide drug derivatives resulting in the release of active drug inside target cells (see, for example, Dubowchik and Walker, 1999, Pharm. Therapeutics 83:67-123). For example, a peptide linker that is cleavable by the thiol-dependent protease cathepsin-B, can be used (for example, a Phenylalanine-Leucine or a Glycine-Phenylalanine-Leucine-Glycine linker). Other examples of such linkers are described, for example, in U.S. Pat. No. 6,214,345, incorporated herein by reference. In a specific embodiment, the peptide linker cleavable by an intracellular protease is a Valine-Citruline linker or a Phenylalanine-Lysine linker (see, for example, U.S. Pat. No. 6,214,345, which describes the synthesis of doxorubicin with the Valine-Citruline linker). 
     In other embodiments, the cleavable linker is pH-sensitive, i.e., sensitive to hydrolysis at certain pH values. Typically, the pH-sensitive linker is hydrolyzable under acidic conditions. For example, an acid-labile linker that is hydrolyzable in the lysosome (for example, a hydrazone, semicarbazone, thiosemicarbazone, cis-aconitic amide, orthoester, acetal, ketal, or the like) can be used. (See, for example, U.S. Pat. Nos. 5,122,368; 5,824,805; 5,622,929; Dubowchik and Walker, 1999, Pharm. Therapeutics 83:67-123; Neville et al., 1989, Biol. Chem. 264:14653-14661.) Such linkers are relatively stable under neutral pH conditions, such as those in the blood, but are unstable at below pH 5.5 or 5.0, the approximate pH of the lysosome. In certain embodiments, the hydrolyzable linker is a thioether linker (such as, for example, a thioether attached to the therapeutic agent via an acylhydrazone bond (see, for example, U.S. Pat. No. 5,622,929). 
     In other embodiments, the linker is cleavable under reducing conditions (for example, a disulfide linker). A variety of disulfide linkers are known in the art, including, for example, those that can be formed using SATA (N-succinimidyl-S-acetylthioacetate), SPDP (N-succinimidyl-3-(2-pyridyldithio)propionate), SPDB (N-succinimidyl-3-(2-pyridyldithio)butyrate) and SMPT (N-succinimidyl-oxycarbonyl-alpha-methyl-alpha-(2-pyridyl-dithio)toluene)-, SPDB and SMPT. (See, for example, Thorpe et al., 1987, Cancer Res. 47:5924-5931; Wawrzynczak et al., In Immunoconjugates: Antibody Conjugates in Radioimagery and Therapy of Cancer (C. W. Vogel ed., Oxford U. Press, 1987); Phillips et al., Cancer Res. 68:92809290, 2008). See also U.S. Pat. No. 4,880,935.) 
     In yet other specific embodiments, the linker is a malonate linker (Johnson et al., 1995, Anticancer Res. 15:1387-93), a maleimidobenzoyl linker (Lau et al., 1995, Bioorg-Med-Chem. 3(10):1299-1304), or a 3′-N-amide analog (Lau et al., 1995, Bioorg-Med-Chem. 3(10):1305-12). 
     In yet other embodiments, the linker is not cleavable and the effector molecule or detectable marker is released by antibody degradation. (See U.S. Publication No. 2005/0238649 incorporated by reference herein in its entirety). 
     In several embodiments, the linker is resistant to cleavage in an extracellular environment. For example, no more than about 20%, no more than about 15%, no more than about 10%, no more than about 5%, no more than about 3%, or no more than about 1% of the linkers, in a sample of conjugate, are cleaved when the conjugate is present in an extracellular environment (for example, in plasma). Whether or not a linker is resistant to cleavage in an extracellular environment can be determined, for example, by incubating the conjugate containing the linker of interest with plasma for a predetermined time period (for example, 2, 4, 8, 16, or 24 hours) and then quantitating the amount of free effector molecule or detectable marker present in the plasma. A variety of exemplary linkers that can be used in conjugates are described in WO 2004-010957, U.S. Publication No. 2006/0074008, U.S. Publication No. 20050238649, and U.S. Publication No. 2006/0024317, each of which is incorporated by reference herein in its entirety. 
     In several embodiments, conjugates of a CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof, and one or more small molecule toxins, such as a calicheamicin, maytansinoids, dolastatins, auristatins, a trichothecene, and CC1065, and the derivatives of these toxins that have toxin activity, are provided. 
     Maytansine compounds suitable for use as maytansinoid toxin moieties are well known in the art, and can be isolated from natural sources according to known methods, produced using genetic engineering techniques (see Yu et al (2002) PNAS 99:7968-7973), or maytansinol and maytansinol analogues prepared synthetically according to known methods. Maytansinoids are mitototic inhibitors which act by inhibiting tubulin polymerization. Maytansine was first isolated from the east African shrub  Maytenus serrata  (U.S. Pat. No. 3,896,111). Subsequently, it was discovered that certain microbes also produce maytansinoids, such as maytansinol and C-3 maytansinol esters (U.S. Pat. No. 4,151,042). Synthetic maytansinol and derivatives and analogues thereof are disclosed, for example, in U.S. Pat. Nos. 4,137,230; 4,248,870; 4,256,746; 4,260,608; 4,265,814; 4,294,757; 4,307,016; 4,308,268; 4,308,269; 4,309,428; 4,313,946; 4,315,929; 4,317,821; 4,322,348; 4,331,598; 4,361,650; 4,364,866; 4,424,219; 4,450,254; 4,362,663; and 4,371,533, each of which is incorporated herein by reference. Conjugates containing maytansinoids, methods of making same, and their therapeutic use are disclosed, for example, in U.S. Pat. Nos. 5,208,020; 5,416,064; 6,441,163 and European Patent EP 0 425 235 B1, the disclosures of which are hereby expressly incorporated by reference. 
     Additional toxins can be employed with a CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof. Exemplary toxins include Pseudomonas exotoxin (PE), ricin, abrin, diphtheria toxin and subunits thereof, ribotoxin, ribonuclease, saporin, and calicheamicin, as well as botulinum toxins A through F. These toxins are well known in the art and many are readily available from commercial sources (for example, Sigma Chemical Company, St. Louis, Mo.). Contemplated toxins also include variants of the toxins (see, for example, see, U.S. Pat. Nos. 5,079,163 and 4,689,401). 
     Saporin is a toxin derived from  Saponaria officinalis  that disrupts protein synthesis by inactivating the 60S portion of the ribosomal complex (Stirpe et al., Bio/Technology, 10:405-412, 1992). However, the toxin has no mechanism for specific entry into cells, and therefore requires conjugation to an antibody or antigen binding fragment that recognizes a cell-surface protein that is internalized in order to be efficiently taken up by cells. 
     Diphtheria toxin is isolated from  Corynebacterium diphtheriae . Typically, diphtheria toxin for use in immunotoxins is mutated to reduce or to eliminate non-specific toxicity. A mutant known as CRM107, which has full enzymatic activity but markedly reduced non-specific toxicity, has been known since the 1970&#39;s (Laird and Groman, J. Virol. 19:220, 1976), and has been used in human clinical trials. See, U.S. Pat. Nos. 5,792,458 and 5,208,021. 
     Ricin is the lectin RCA60 from  Ricinus communis  (Castor bean). For examples of ricin, see, U.S. Pat. Nos. 5,079,163 and 4,689,401.  Ricinus communis  agglutinin (RCA) occurs in two forms designated RCA 60  and RCA 120  according to their molecular weights of approximately 65 and 120 kD, respectively (Nicholson &amp; Blaustein, J. Biochim. Biophys. Acta 266:543, 1972). The A chain is responsible for inactivating protein synthesis and killing cells. The B chain binds ricin to cell-surface galactose residues and facilitates transport of the A chain into the cytosol (Olsnes et al., Nature 249:627-631, 1974 and U.S. Pat. No. 3,060,165). 
     Ribonucleases have also been conjugated to targeting molecules for use as immunotoxins (see Suzuki et al., Nat. Biotech. 17:265-70, 1999). Exemplary ribotoxins such as α-sarcin and restrictocin are discussed in, for example Rathore et al., Gene 190:31-5, 1997; and Goyal and Batra, Biochem. 345 Pt 2:247-54, 2000. Calicheamicins were first isolated from  Micromonospora echinospora  and are members of the enediyne antitumor antibiotic family that cause double strand breaks in DNA that lead to apoptosis (see, for example Lee et al., J. Antibiot. 42:1070-87,1989). The drug is the toxic moiety of an immunotoxin in clinical trials (see, for example, Gillespie et al.,  Ann. Oncol.  11:735-41, 2000). 
     Abrin includes toxic lectins from  Abrus precatorius . The toxic principles, abrin a, b, c, and d, have a molecular weight of from about 63 and 67 kD and are composed of two disulfide-linked polypeptide chains A and B. The A chain inhibits protein synthesis; the B chain (abrin-b) binds to D-galactose residues (see, Funatsu et al., Agr. Biol. Chem. 52:1095, 1988; and Olsnes, Methods Enzymol. 50:330-335, 1978). 
     A CAR, a T cell expressing a CAR, monoclonal antibodies, antigen binding fragments thereof, specific for one or more of the antigens disclosed herein, can also be conjugated with a detectable marker; for example, a detectable marker capable of detection by ELISA, spectrophotometry, flow cytometry, microscopy or diagnostic imaging techniques (such as computed tomography (CT), computed axial tomography (CAT) scans, magnetic resonance imaging (MRI), nuclear magnetic resonance imaging NMRI), magnetic resonance tomography (MTR), ultrasound, fiberoptic examination, and laparoscopic examination). Specific, non-limiting examples of detectable markers include fluorophores, chemiluminescent agents, enzymatic linkages, radioactive isotopes and heavy metals or compounds (for example super paramagnetic iron oxide nanocrystals for detection by MRI). For example, useful detectable markers include fluorescent compounds, including fluorescein, fluorescein isothiocyanate, rhodamine, 5-dimethylamine-1-napthalenesulfonyl chloride, phycoerythrin, lanthanide phosphors and the like. Bioluminescent markers are also of use, such as luciferase, Green fluorescent protein (GFP), Yellow fluorescent protein (YFP). A CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof, can also be conjugated with enzymes that are useful for detection, such as horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase, glucose oxidase and the like. When a CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof, is conjugated with a detectable enzyme, it can be detected by adding additional reagents that the enzyme uses to produce a reaction product that can be discerned. For example, when the agent horseradish peroxidase is present the addition of hydrogen peroxide and diaminobenzidine leads to a colored reaction product, which is visually detectable. A CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof, may also be conjugated with biotin, and detected through indirect measurement of avidin or streptavidin binding. It should be noted that the avidin itself can be conjugated with an enzyme or a fluorescent label. 
     A CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof, may be conjugated with a paramagnetic agent, such as gadolinium. Paramagnetic agents such as superparamagnetic iron oxide are also of use as labels. Antibodies can also be conjugated with lanthanides (such as europium and dysprosium), and manganese. An antibody or antigen binding fragment may also be labeled with a predetermined polypeptide epitopes recognized by a secondary reporter (such as leucine zipper pair sequences, binding sites for secondary antibodies, metal binding domains, epitope tags). 
     A CAR, a T cell expressing a CAR, an antibody, or antigen binding portion thereof, can also be conjugated with a radiolabeled amino acid. The radiolabel may be used for both diagnostic and therapeutic purposes. For instance, the radiolabel may be used to detect one or more of the antigens disclosed herein and antigen expressing cells by x-ray, emission spectra, or other diagnostic techniques. Further, the radiolabel may be used therapeutically as a toxin for treatment of tumors in a subject, for example for treatment of a neuroblastoma. Examples of labels for polypeptides include, but are not limited to, the following radioisotopes or radionucleotides:  3 H,  14 C,  15 N,  35 S,  90 Y,  99 Tc,  111 In,  125 I, and  131 I. 
     Means of detecting such detectable markers are well known to those of skill in the art. Thus, for example, radiolabels may be detected using photographic film or scintillation counters, fluorescent markers may be detected using a photodetector to detect emitted illumination. Enzymatic labels are typically detected by providing the enzyme with a substrate and detecting the reaction product produced by the action of the enzyme on the substrate, and colorimetric labels are detected by simply visualizing the colored label. 
     D. Nucleotides, Expression, Vectors, and Host Cells 
     Further provided by an embodiment of the invention is a nucleic acid comprising a nucleotide sequence encoding any of the CARs, an antibody, or antigen binding portion thereof, described herein (including functional portions and functional variants thereof). The nucleic acids of the invention may comprise a nucleotide sequence encoding any of the leader sequences, antigen binding domains, transmembrane domains, and/or intracellular T cell signaling domains described herein. 
     In some embodiments, the nucleotide sequence may be codon-modified. Without being bound to a particular theory, it is believed that codon optimization of the nucleotide sequence increases the translation efficiency of the mRNA transcripts. Codon optimization of the nucleotide sequence may involve substituting a native codon for another codon that encodes the same amino acid, but can be translated by tRNA that is more readily available within a cell, thus increasing translation efficiency. Optimization of the nucleotide sequence may also reduce secondary mRNA structures that would interfere with translation, thus increasing translation efficiency. 
     In an embodiment of the invention, the nucleic acid may comprise a codon-modified nucleotide sequence that encodes the antigen binding domain of the inventive CAR. In another embodiment of the invention, the nucleic acid may comprise a codon-modified nucleotide sequence that encodes any of the CARs described herein (including functional portions and functional variants thereof). 
     “Nucleic acid” as used herein includes “polynucleotide,” “oligonucleotide,” and “nucleic acid molecule,” and generally means a polymer of DNA or RNA, which can be single-stranded or double-stranded, synthesized or obtained (e.g., isolated and/or purified) from natural sources, which can contain natural, non-natural or altered nucleotides, and which can contain a natural, non-natural or altered internucleotide linkage, such as a phosphoroamidate linkage or a phosphorothioate linkage, instead of the phosphodiester found between the nucleotides of an unmodified oligonucleotide. In some embodiments, the nucleic acid does not comprise any insertions, deletions, inversions, and/or substitutions. However, it may be suitable in some instances, as discussed herein, for the nucleic acid to comprise one or more insertions, deletions, inversions, and/or substitutions. 
     A recombinant nucleic acid may be one that has a sequence that is not naturally occurring or has a sequence that is made by an artificial combination of two otherwise separated segments of sequence. This artificial combination is often accomplished by chemical synthesis or, more commonly, by the artificial manipulation of isolated segments of nucleic acids, e.g., by genetic engineering techniques, such as those described in Sambrook et al., supra. The nucleic acids can be constructed based on chemical synthesis and/or enzymatic ligation reactions using procedures known in the art. See, for example, Sambrook et al., supra, and Ausubel et al., supra. For example, a nucleic acid can be chemically synthesized using naturally occurring nucleotides or variously modified nucleotides designed to increase the biological stability of the molecules or to increase the physical stability of the duplex formed upon hybridization (e.g., phosphorothioate derivatives and acridine substituted nucleotides). Examples of modified nucleotides that can be used to generate the nucleic acids include, but are not limited to, 5-fluorouracil, 5-bromouracil, 5-chlorouracil, 5-iodouracil, hypoxanthine, xanthine, 4-acetylcytosine, 5-(carboxyhydroxymethyl) uracil, 5-carboxymethylaminomethyl-2-thiouridine, 5-carboxymethylaminomethyluracil, dihydrouracil, beta-D-galactosylqueosine, inosine, N6-isopentenyladenine, 1-methylguanine, 1-methylinosine, 2,2-dimethylguanine, 2-methyladenine, 2-methylguanine, 3-methylcytosine, 5-methylcytosine, N6-substituted adenine, 7-methylguanine, 5-methylaminomethyluracil, 5-methoxyaminomethyl-2-thiouracil, beta-D-mannosylqueosine, 5′-methoxycarboxymethyluracil, 5-methoxyuracil, 2-methylthio-N6-isopentenyladenine, uracil-5-oxyacetic acid (v), wybutoxosine, pseudouracil, queosine, 2-thiocytosine, 5-methyl-2-thiouracil, 2-thiouracil, 4-thiouracil, 5-methyluracil, uracil-5-oxyacetic acid methylester, 3-(3-amino-3-N-2-carboxypropyl) uracil, and 2,6-diaminopurine. Alternatively, one or more of the nucleic acids of the invention can be purchased from companies, such as Integrated DNA Technologies (Coralville, Iowa, USA). 
     The nucleic acid can comprise any isolated or purified nucleotide sequence which encodes any of the CARs or functional portions or functional variants thereof. Alternatively, the nucleotide sequence can comprise a nucleotide sequence which is degenerate to any of the sequences or a combination of degenerate sequences. 
     An embodiment also provides an isolated or purified nucleic acid comprising a nucleotide sequence which is complementary to the nucleotide sequence of any of the nucleic acids described herein or a nucleotide sequence which hybridizes under stringent conditions to the nucleotide sequence of any of the nucleic acids described herein. 
     The nucleotide sequence which hybridizes under stringent conditions may hybridize under high stringency conditions. By “high stringency conditions” is meant that the nucleotide sequence specifically hybridizes to a target sequence (the nucleotide sequence of any of the nucleic acids described herein) in an amount that is detectably stronger than non-specific hybridization. High stringency conditions include conditions which would distinguish a polynucleotide with an exact complementary sequence, or one containing only a few scattered mismatches from a random sequence that happened to have a few small regions (e.g., 3-10 bases) that matched the nucleotide sequence. Such small regions of complementarity are more easily melted than a full-length complement of 14-17 or more bases, and high stringency hybridization makes them easily distinguishable. Relatively high stringency conditions would include, for example, low salt and/or high temperature conditions, such as provided by about 0.02-0.1 M NaCl or the equivalent, at temperatures of about 50-70° C. Such high stringency conditions tolerate little, if any, mismatch between the nucleotide sequence and the template or target strand, and are particularly suitable for detecting expression of any of the inventive CARs. It is generally appreciated that conditions can be rendered more stringent by the addition of increasing amounts of formamide. 
     Also provided is a nucleic acid comprising a nucleotide sequence that is at least about 70% or more, e.g., about 80%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, or about 99% identical to any of the nucleic acids described herein. 
     In an embodiment, the nucleic acids can be incorporated into a recombinant expression vector. In this regard, an embodiment provides recombinant expression vectors comprising any of the nucleic acids. For purposes herein, the term “recombinant expression vector” means a genetically-modified oligonucleotide or polynucleotide construct that permits the expression of an mRNA, protein, polypeptide, or peptide by a host cell, when the construct comprises a nucleotide sequence encoding the mRNA, protein, polypeptide, or peptide, and the vector is contacted with the cell under conditions sufficient to have the mRNA, protein, polypeptide, or peptide expressed within the cell. The vectors are not naturally-occurring as a whole. 
     However, parts of the vectors can be naturally-occurring. The recombinant expression vectors can comprise any type of nucleotides, including, but not limited to DNA and RNA, which can be single-stranded or double-stranded, synthesized or obtained in part from natural sources, and which can contain natural, non-natural or altered nucleotides. The recombinant expression vectors can comprise naturally-occurring or non-naturally-occurring internucleotide linkages, or both types of linkages. Preferably, the non-naturally occurring or altered nucleotides or internucleotide linkages do not hinder the transcription or replication of the vector. 
     In an embodiment, the recombinant expression vector can be any suitable recombinant expression vector, and can be used to transform or transfect any suitable host cell. Suitable vectors include those designed for propagation and expansion or for expression or both, such as plasmids and viruses. The vector can be selected from the group consisting of the pUC series (Fermentas Life Sciences, Glen Burnie, Md.), the pBluescript series (Stratagene, LaJolla, Calif.), the pET series (Novagen, Madison, Wis.), the pGEX series (Pharmacia Biotech, Uppsala, Sweden), and the pEX series (Clontech, Palo Alto, Calif.). 
     Bacteriophage vectors, such as λ{circumflex over (ν)}TIO, λ{circumflex over (ν)}TI 1, λZapII (Stratagene), EMBL4, and λNMI 149, also can be used. Examples of plant expression vectors include pBIO1, pBI101.2, pBHO1.3, pBI121 and pBIN19 (Clontech). Examples of animal expression vectors include pEUK-Cl, pMAM, and pMAMneo (Clontech). The recombinant expression vector may be a viral vector, e.g., a retroviral vector or a lentiviral vector. A lentiviral vector is a vector derived from at least a portion of a lentivirus genome, including especially a self-inactivating lentiviral vector as provided in Milone et al., Mol. Ther. 17(8): 1453-1464 (2009). Other examples of lentivirus vectors that may be used in the clinic, include, for example, and not by way of limitation, the LENTIVECTOR® gene delivery technology from Oxford BioMedica plc, the LENTIMAX™ vector system from Lentigen and the like. Nonclinical types of lentiviral vectors are also available and would be known to one skilled in the art. 
     A number of transfection techniques are generally known in the art (see, e.g., Graham et al., Virology, 52: 456-467 (1973); Sambrook et al., supra; Davis et al., Basic Methods in Molecular Biology, Elsevier (1986); and Chu et al, Gene, 13: 97 (1981). 
     Transfection methods include calcium phosphate co-precipitation (see, e.g., Graham et al., supra), direct micro injection into cultured cells (see, e.g., Capecchi, Cell, 22: 479-488 (1980)), electroporation (see, e.g., Shigekawa et al., BioTechniques, 6: 742-751 (1988)), liposome mediated gene transfer (see, e.g., Mannino et al., BioTechniques, 6: 682-690 (1988)), lipid mediated transduction (see, e.g., Feigner et al., Proc. Natl. Acad. Sci. USA, 84: 7413-7417 (1987)), and nucleic acid delivery using high velocity microprojectiles (see, e.g., Klein et al, Nature, 327: 70-73 (1987)). 
     In an embodiment, the recombinant expression vectors can be prepared using standard recombinant DNA techniques described in, for example, Sambrook et al., supra, and Ausubel et al., supra. Constructs of expression vectors, which are circular or linear, can be prepared to contain a replication system functional in a prokaryotic or eukaryotic host cell. Replication systems can be derived, e.g., from ColE1, 2μ plasmid, λ, SV40, bovine papilloma virus, and the like. 
     The recombinant expression vector may comprise regulatory sequences, such as transcription and translation initiation and termination codons, which are specific to the type of host cell (e.g., bacterium, fungus, plant, or animal) into which the vector is to be introduced, as appropriate, and taking into consideration whether the vector is DNA- or RNA-based. The recombinant expression vector may comprise restriction sites to facilitate cloning. 
     The recombinant expression vector can include one or more marker genes, which allow for selection of transformed or transfected host cells. Marker genes include biocide resistance, e.g., resistance to antibiotics, heavy metals, etc., complementation in an auxotrophic host to provide prototrophy, and the like. Suitable marker genes for the inventive expression vectors include, for instance, neomycin/G418 resistance genes, hygromycin resistance genes, histidinol resistance genes, tetracycline resistance genes, and ampicillin resistance genes. 
     The recombinant expression vector can comprise a native or nonnative promoter operably linked to the nucleotide sequence encoding the CAR (including functional portions and functional variants thereof), or to the nucleotide sequence which is complementary to or which hybridizes to the nucleotide sequence encoding the CAR. The selection of promoters, e.g., strong, weak, inducible, tissue-specific and developmental-specific, is within the ordinary skill of the artisan. Similarly, the combining of a nucleotide sequence with a promoter is also within the skill of the artisan. The promoter can be a non-viral promoter or a viral promoter, e.g., a cytomegalovirus (CMV) promoter, an SV40 promoter, an RSV promoter, or a promoter found in the long-terminal repeat of the murine stem cell virus. 
     The recombinant expression vectors can be designed for either transient expression, for stable expression, or for both. Also, the recombinant expression vectors can be made for constitutive expression or for inducible expression. 
     Further, the recombinant expression vectors can be made to include a suicide gene. As used herein, the term “suicide gene” refers to a gene that causes the cell expressing the suicide gene to die. The suicide gene can be a gene that confers sensitivity to an agent, e.g., a drug, upon the cell in which the gene is expressed, and causes the cell to die when the cell is contacted with or exposed to the agent. Suicide genes are known in the art (see, for example, Suicide Gene Therapy: Methods and Reviews, Springer, Caroline J. (Cancer Research UK Centre for Cancer Therapeutics at the Institute of Cancer Research, Sutton, Surrey, UK), Humana Press, 2004) and include, for example, the Herpes Simplex Virus (HSV) thymidine kinase (TK) gene, cytosine daminase, purine nucleoside phosphorylase, and nitroreductase. 
     An embodiment further provides a host cell comprising any of the recombinant expression vectors described herein. As used herein, the term “host cell” refers to any type of cell that can contain the inventive recombinant expression vector. The host cell can be a eukaryotic cell, e.g., plant, animal, fungi, or algae, or can be a prokaryotic cell, e.g., bacteria or protozoa. The host cell can be a cultured cell or a primary cell, i.e., isolated directly from an organism, e.g., a human. The host cell can be an adherent cell or a suspended cell, i.e., a cell that grows in suspension. Suitable host cells are known in the art and include, for instance, DH5a  E. coli  cells, Chinese hamster ovarian cells, monkey VERO cells, COS cells, HEK293 cells, and the like. For purposes of amplifying or replicating the recombinant expression vector, the host cell may be a prokaryotic cell, e.g., a DH5a cell. For purposes of producing a recombinant CAR, the host cell may be a mammalian cell. The host cell may be a human cell. While the host cell can be of any cell type, can originate from any type of tissue, and can be of any developmental stage, the host cell may be a peripheral blood lymphocyte (PBL) or a peripheral blood mononuclear cell (PBMC). The host cell may be a T cell. 
     For purposes herein, the T cell can be any T cell, such as a cultured T cell, e.g., a primary T cell, or a T cell from a cultured T cell line, e.g., Jurkat, SupT1, etc., or a T cell obtained from a mammal. If obtained from a mammal, the T cell can be obtained from numerous sources, including but not limited to blood, bone marrow, lymph node, the thymus, or other tissues or fluids. T cells can also be enriched for or purified. The T cell may be a human T cell. The T cell may be a T cell isolated from a human. The T cell can be any type of T cell and can be of any developmental stage, including but not limited to, CD4+/CD8+ double positive T cells, CD4+ helper T cells, e.g., Th1 and Th2 cells, CD8+ T cells (e.g., cytotoxic T cells), tumor infiltrating cells, memory T cells, memory stem cells, i.e. Tscm, naive T cells, and the like. The T cell may be a CD8+ T cell or a CD4+ T cell. 
     In an embodiment, the CARs as described herein can be used in suitable non-T cells. Such cells are those with an immune-effector function, such as, for example, NK cells, and T-like cells generated from pluripotent stem cells. 
     Also provided by an embodiment is a population of cells comprising at least one host cell described herein. The population of cells can be a heterogeneous population comprising the host cell comprising any of the recombinant expression vectors described, in addition to at least one other cell, e.g., a host cell (e.g., a T cell), which does not comprise any of the recombinant expression vectors, or a cell other than a T cell, e.g., a B cell, a macrophage, a neutrophil, an erythrocyte, a hepatocyte, an endothelial cell, an epithelial cell, a muscle cell, a brain cell, etc. Alternatively, the population of cells can be a substantially homogeneous population, in which the population comprises mainly host cells (e.g., consisting essentially of) comprising the recombinant expression vector. The population also can be a clonal population of cells, in which all cells of the population are clones of a single host cell comprising a recombinant expression vector, such that all cells of the population comprise the recombinant expression vector. In one embodiment of the invention, the population of cells is a clonal population comprising host cells comprising a recombinant expression vector as described herein. 
     CARs (including functional portions and variants thereof), nucleic acids, recombinant expression vectors, host cells (including populations thereof), and antibodies (including antigen binding portions thereof), can be isolated and/or purified. For example, a purified (or isolated) host cell preparation is one in which the host cell is more pure than cells in their natural environment within the body. Such host cells may be produced, for example, by standard purification techniques. In some embodiments, a preparation of a host cell is purified such that the host cell represents at least about 50%, for example at least about 70%, of the total cell content of the preparation. For example, the purity can be at least about 50%, can be greater than about 60%, about 70% or about 80%, or can be about 100%. 
     E. Methods of Treatment 
     It is contemplated that the CARs disclosed herein can be used in methods of treating or preventing a disease in a mammal. In this regard, an embodiment provides a method of treating or preventing cancer in a mammal, comprising administering to the mammal the CARs, the nucleic acids, the recombinant expression vectors, the host cells, the population of cells, the antibodies and/or the antigen binding portions thereof, and/or the pharmaceutical compositions in an amount effective to treat or prevent cancer in the mammal. 
     An embodiment further comprises lymphodepleting the mammal prior to administering the CARs disclosed herein. Examples of lymphodepletion include, but may not be limited to, nonmyeloablative lymphodepleting chemotherapy, myeloablative lymphodepleting chemotherapy, total body irradiation, etc. 
     For purposes of the methods, wherein host cells or populations of cells are administered, the cells can be cells that are allogeneic or autologous to the mammal. Preferably, the cells are autologous to the mammal. As used herein, allogeneic means any material derived from a different animal of the same species as the individual to whom the material is introduced. Two or more individuals are said to be allogeneic to one another when the genes at one or more loci are not identical. In some aspects, allogeneic material from individuals of the same species may be sufficiently unlike genetically to interact antigenically. As used herein, “autologous” means any material derived from the same individual to whom it is later to be re-introduced into the individual. 
     The mammal referred to herein can be any mammal. As used herein, the term “mammal” refers to any mammal, including, but not limited to, mammals of the order Rodentia, such as mice and hamsters, and mammals of the order Logomorpha, such as rabbits. The mammals may be from the order Carnivora, including Felines (cats) and Canines (dogs). The mammals may be from the order Artiodactyla, including Bovines (cows) and Swines (pigs) or of the order Perssodactyla, including Equines (horses). The mammals may be of the order Primates, Ceboids, or Simoids (monkeys) or of the order Anthropoids (humans and apes). Preferably, the mammal is a human. 
     With respect to the methods, the cancer can be any cancer, including any of acute lymphocytic cancer, acute myeloid leukemia, alveolar rhabdomyosarcoma, bladder cancer (e.g., bladder carcinoma), bone cancer, brain cancer (e.g., meduloblastoma), breast cancer, cancer of the anus, anal canal, or anorectum, cancer of the eye, cancer of the intrahepatic bile duct, cancer of the joints, cancer of the neck, gallbladder, or pleura, cancer of the nose, nasal cavity, or middle ear, cancer of the oral cavity, cancer of the vulva, chronic lymphocytic leukemia, chronic myeloid cancer, colon cancer, esophageal cancer, cervical cancer, fibrosarcoma, gastrointestinal carcinoid tumor, head and neck cancer (e.g., head and neck squamous cell carcinoma), Hodgkin lymphoma, hypopharynx cancer, kidney cancer, larynx cancer, leukemia, liquid tumors, liver cancer, lung cancer (e.g., non-small cell lung carcinoma and lung adenocarcinoma), lymphoma, mesothelioma, mastocytoma, melanoma, multiple myeloma, nasopharynx cancer, non-Hodgkin lymphoma, B-chronic lymphocytic leukemia, hairy cell leukemia, acute lymphocytic leukemia (ALL), and Burkitt&#39;s lymphoma, ovarian cancer, pancreatic cancer, peritoneum, omentum, and mesentery cancer, pharynx cancer, prostate cancer, rectal cancer, renal cancer, skin cancer, small intestine cancer, soft tissue cancer, solid tumors, synovial sarcoma, gastric cancer, testicular cancer, thyroid cancer, and ureter cancer. 
     The terms “treat,” and “prevent” as well as words stemming therefrom, as used herein, do not necessarily imply 100% or complete treatment or prevention. Rather, there are varying degrees of treatment or prevention of which one of ordinary skill in the art recognizes as having a potential benefit or therapeutic effect. In this respect, the methods can provide any amount or any level of treatment or prevention of cancer in a mammal. 
     Furthermore, the treatment or prevention provided by the method can include treatment or prevention of one or more conditions or symptoms of the disease, e.g., cancer, being treated or prevented. Also, for purposes herein, “prevention” can encompass delaying the onset of the disease, or a symptom or condition thereof. 
     Another embodiment provides a method of detecting the presence of cancer in a mammal, comprising: (a) contacting a sample comprising one or more cells from the mammal with the CARs, the nucleic acids, the recombinant expression vectors, the host cells, the population of cells, the antibodies, and/or the antigen binding portions thereof, or the pharmaceutical compositions, thereby forming a complex, (b) and detecting the complex, wherein detection of the complex is indicative of the presence of cancer in the mammal. 
     The sample may be obtained by any suitable method, e.g., biopsy or necropsy. A biopsy is the removal of tissue and/or cells from an individual. Such removal may be to collect tissue and/or cells from the individual in order to perform experimentation on the removed tissue and/or cells. This experimentation may include experiments to determine if the individual has and/or is suffering from a certain condition or disease-state. The condition or disease may be, e.g., cancer. 
     With respect to an embodiment of the method of detecting the presence of a proliferative disorder, e.g., cancer, in a mammal, the sample comprising cells of the mammal can be a sample comprising whole cells, lysates thereof, or a fraction of the whole cell lysates, e.g., a nuclear or cytoplasmic fraction, a whole protein fraction, or a nucleic acid fraction. If the sample comprises whole cells, the cells can be any cells of the mammal, e.g., the cells of any organ or tissue, including blood cells or endothelial cells. 
     The contacting can take place in vitro or in vivo with respect to the mammal. Preferably, the contacting is in vitro. 
     Also, detection of the complex can occur through any number of ways known in the art. For instance, the CARs disclosed herein, polypeptides, proteins, nucleic acids, recombinant expression vectors, host cells, populations of cells, or antibodies, or antigen binding portions thereof, described herein, can be labeled with a detectable label such as, for instance, a radioisotope, a fluorophore (e.g., fluorescein isothiocyanate (FITC), phycoerythrin (PE)), an enzyme (e.g., alkaline phosphatase, horseradish peroxidase), and element particles (e.g., gold particles) as disclosed supra. 
     Methods of testing a CAR for the ability to recognize target cells and for antigen specificity are known in the art. For instance, Clay et al., J. Immunol, 163: 507-513 (1999), teaches methods of measuring the release of cytokines (e.g., interferon-γ, granulocyte/monocyte colony stimulating factor (GM-CSF), tumor necrosis factor a (TNF-a) or interleukin 2 (IL-2)). In addition, CAR function can be evaluated by measurement of cellular cytotoxicity, as described in Zhao et al, J. Immunol, 174: 4415-4423 (2005). 
     Another embodiment provides for the use of the CARs, nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and/or pharmaceutical compositions of the invention, for the treatment or prevention of a proliferative disorder, e.g., cancer, in a mammal. The cancer may be any of the cancers described herein. 
     Any method of administration can be used for the disclosed therapeutic agents, including local and systemic administration. For example topical, oral, intravascular such as intravenous, intramuscular, intraperitoneal, intranasal, intradermal, intrathecal and subcutaneous administration can be used. The particular mode of administration and the dosage regimen will be selected by the attending clinician, taking into account the particulars of the case (for example the subject, the disease, the disease state involved, and whether the treatment is prophylactic). In cases in which more than one agent or composition is being administered, one or more routes of administration may be used; for example, a chemotherapeutic agent may be administered orally and an antibody or antigen binding fragment or conjugate or composition may be administered intravenously. Methods of administration include injection for which the CAR, CAR T Cell, conjugates, antibodies, antigen binding fragments, or compositions are provided in a nontoxic pharmaceutically acceptable carrier such as water, saline, Ringer&#39;s solution, dextrose solution, 5% human serum albumin, fixed oils, ethyl oleate, or liposomes. In some embodiments, local administration of the disclosed compounds can be used, for instance by applying the antibody or antigen binding fragment to a region of tissue from which a tumor has been removed, or a region suspected of being prone to tumor development. In some embodiments, sustained intra-tumoral (or near-tumoral) release of the pharmaceutical preparation that includes a therapeutically effective amount of the antibody or antigen binding fragment may be beneficial. In other examples, the conjugate is applied as an eye drop topically to the cornea, or intravitreally into the eye. 
     The disclosed therapeutic agents can be formulated in unit dosage form suitable for individual administration of precise dosages. In addition, the disclosed therapeutic agents may be administered in a single dose or in a multiple dose schedule. A multiple dose schedule is one in which a primary course of treatment may be with more than one separate dose, for instance 1-10 doses, followed by other doses given at subsequent time intervals as needed to maintain or reinforce the action of the compositions. Treatment can involve daily or multi-daily doses of compound(s) over a period of a few days to months, or even years. Thus, the dosage regime will also, at least in part, be determined based on the particular needs of the subject to be treated and will be dependent upon the judgment of the administering practitioner. 
     Typical dosages of the antibodies or conjugates can range from about 0.01 to about 30 mg/kg, such as from about 0.1 to about 10 mg/kg. 
     In particular examples, the subject is administered a therapeutic composition that includes one or more of the conjugates, antibodies, compositions, CARs, CAR T cells or additional agents, on a multiple daily dosing schedule, such as at least two consecutive days, 10 consecutive days, and so forth, for example for a period of weeks, months, or years. In one example, the subject is administered the conjugates, antibodies, compositions or additional agents for a period of at least 30 days, such as at least 2 months, at least 4 months, at least 6 months, at least 12 months, at least 24 months, or at least 36 months. 
     In some embodiments, the disclosed methods include providing surgery, radiation therapy, and/or chemotherapeutics to the subject in combination with a disclosed antibody, antigen binding fragment, conjugate, CAR or T cell expressing a CAR (for example, sequentially, substantially simultaneously, or simultaneously). Methods and therapeutic dosages of such agents and treatments are known to those skilled in the art, and can be determined by a skilled clinician. Preparation and dosing schedules for the additional agent may be used according to manufacturer&#39;s instructions or as determined empirically by the skilled practitioner. Preparation and dosing schedules for such chemotherapy are also described in Chemotherapy Service, (1992) Ed., M. C. Perry, Williams &amp; Wilkins, Baltimore, Md. 
     In some embodiments, the combination therapy can include administration of a therapeutically effective amount of an additional cancer inhibitor to a subject. Non-limiting examples of additional therapeutic agents that can be used with the combination therapy include microtubule binding agents, DNA intercalators or cross-linkers, DNA synthesis inhibitors, DNA and RNA transcription inhibitors, antibodies, enzymes, enzyme inhibitors, gene regulators, and angiogenesis inhibitors. These agents (which are administered at a therapeutically effective amount) and treatments can be used alone or in combination. For example, any suitable anti-cancer or anti-angiogenic agent can be administered in combination with the CARS, CAR-T cells, antibodies, antigen binding fragment, or conjugates disclosed herein. Methods and therapeutic dosages of such agents are known to those skilled in the art, and can be determined by a skilled clinician. 
     Additional chemotherapeutic agents include, but are not limited to alkylating agents, such as nitrogen mustards (for example, chlorambucil, chlormethine, cyclophosphamide, ifosfamide, and melphalan), nitrosoureas (for example, carmustine, fotemustine, lomustine, and streptozocin), platinum compounds (for example, carboplatin, cisplatin, oxaliplatin, and BBR3464), busulfan, dacarbazine, mechlorethamine, procarbazine, temozolomide, thiotepa, and uramustine; antimetabolites, such as folic acid (for example, methotrexate, pemetrexed, and raltitrexed), purine (for example, cladribine, clofarabine, fludarabine, mercaptopurine, and tioguanine), pyrimidine (for example, capecitabine), cytarabine, fluorouracil, and gemcitabine; plant alkaloids, such as podophyllum (for example, etoposide, and teniposide), taxane (for example, docetaxel and paclitaxel), vinca (for example, vinblastine, vincristine, vindesine, and vinorelbine); cytotoxic/antitumor antibiotics, such as anthracycline family members (for example, daunorubicin, doxorubicin, epirubicin, idarubicin, mitoxantrone, and valrubicin), bleomycin, rifampicin, hydroxyurea, and mitomycin; topoisomerase inhibitors, such as topotecan and irinotecan; monoclonal antibodies, such as alemtuzumab, bevacizumab, cetuximab, gemtuzumab, rituximab, panitumumab, pertuzumab, and trastuzumab; photosensitizers, such as aminolevulinic acid, methyl aminolevulinate, porfimer sodium, and verteporfin; and other agents, such as alitretinoin, altretamine, amsacrine, anagrelide, arsenic trioxide, asparaginase, axitinib, bexarotene, bevacizumab, bortezomib, celecoxib, denileukin diftitox, erlotinib, estramustine, gefitinib, hydroxycarbamide, imatinib, lapatinib, pazopanib, pentostatin, masoprocol, mitotane, pegaspargase, tamoxifen, sorafenib, sunitinib, vemurafinib, vandetanib, and tretinoin. Selection and therapeutic dosages of such agents are known to those skilled in the art, and can be determined by a skilled clinician. 
     The combination therapy may provide synergy and prove synergistic, that is, the effect achieved when the active ingredients used together is greater than the sum of the effects that results from using the compounds separately. A synergistic effect may be attained when the active ingredients are: (1) co-formulated and administered or delivered simultaneously in a combined, unit dosage formulation; (2) delivered by alternation or in parallel as separate formulations; or (3) by some other regimen. When delivered in alternation, a synergistic effect may be attained when the compounds are administered or delivered sequentially, for example by different injections in separate syringes. In general, during alternation, an effective dosage of each active ingredient is administered sequentially, i.e. serially, whereas in combination therapy, effective dosages of two or more active ingredients are administered together. 
     In one embodiment, an effective amount of an antibody or antigen binding fragment that specifically binds to one or more of the antigens disclosed herein or a conjugate thereof is administered to a subject having a tumor following anti-cancer treatment. After a sufficient amount of time has elapsed to allow for the administered antibody or antigen binding fragment or conjugate to form an immune complex with the antigen expressed on the respective cancer cell, the immune complex is detected. The presence (or absence) of the immune complex indicates the effectiveness of the treatment. For example, an increase in the immune complex compared to a control taken prior to the treatment indicates that the treatment is not effective, whereas a decrease in the immune complex compared to a control taken prior to the treatment indicates that the treatment is effective. 
     F. Biopharmaceutical Compositions 
     Biopharmaceutical or biologics compositions (hereinafter, “compositions”) are provided herein for use in gene therapy, immunotherapy and/or cell therapy that include one or more of the disclosed CARs, or T cells expressing a CAR, antibodies, antigen binding fragments, conjugates, CARs, or T cells expressing a CAR that specifically bind to one or more antigens disclosed herein, in a carrier (such as a pharmaceutically acceptable carrier). The compositions can be prepared in unit dosage forms for administration to a subject. The amount and timing of administration are at the discretion of the treating clinician to achieve the desired outcome. The compositions can be formulated for systemic (such as intravenus) or local (such as intra-tumor) administration. In one example, a disclosed CARs, or T cells expressing a CAR, antibody, antigen binding fragment, conjugate, is formulated for parenteral administration, such as intravenous administration. Compositions including a CAR, or T cell expressing a CAR, a conjugate, antibody or antigen binding fragment as disclosed herein are of use, for example, for the treatment and detection of a tumor, for example, and not by way of limitation, a neuroblastoma. In some examples, the compositions are useful for the treatment or detection of a carcinoma. The compositions including a CAR, or T cell expressing a CAR, a conjugate, antibody or antigen binding fragment as disclosed herein are also of use, for example, for the detection of pathological angiogenesis. 
     The compositions for administration can include a solution of the CAR, or T cell expressing a CAR, conjugate, antibody or antigen binding fragment dissolved in a pharmaceutically acceptable carrier, such as an aqueous carrier. A variety of aqueous carriers can be used, for example, buffered saline and the like. These solutions are sterile and generally free of undesirable matter. These compositions may be sterilized by conventional, well known sterilization techniques. The compositions may contain pharmaceutically acceptable auxiliary substances as required to approximate physiological conditions such as pH adjusting and buffering agents, toxicity adjusting agents, adjuvant agents, and the like, for example, sodium acetate, sodium chloride, potassium chloride, calcium chloride, sodium lactate and the like. The concentration of a CAR, or T cell expressing a CAR, antibody or antigen binding fragment or conjugate in these formulations can vary widely, and will be selected primarily based on fluid volumes, viscosities, body weight and the like in accordance with the particular mode of administration selected and the subject&#39;s needs. Actual methods of preparing such dosage forms for use in in gene therapy, immunotherapy and/or cell therapy are known, or will be apparent, to those skilled in the art. 
     A typical composition for intravenous administration includes about 0.01 to about 30 mg/kg of antibody or antigen binding fragment or conjugate per subject per day (or the corresponding dose of a CAR, or T cell expressing a CAR, conjugate including the antibody or antigen binding fragment). Actual methods for preparing administrable compositions will be known or apparent to those skilled in the art and are described in more detail in such publications as  Remington&#39;s Pharmaceutical Science,  19th ed., Mack Publishing Company, Easton, Pa. (1995). 
     A CAR, or T cell expressing a CAR, antibodies, antigen binding fragments, or conjugates may be provided in lyophilized form and rehydrated with sterile water before administration, although they are also provided in sterile solutions of known concentration. The CARs, or T cells expressing a CAR, antibody or antigen binding fragment or conjugate solution is then added to an infusion bag containing 0.9% sodium chloride, USP, and in some cases administered at a dosage of from 0.5 to 15 mg/kg of body weight. Considerable experience is available in the art in the administration of antibody or antigen binding fragment and conjugate drugs; for example, antibody drugs have been marketed in the U.S. since the approval of RITUXAN® in 1997. A CAR, or T cell expressing a CAR, antibodies, antigen binding fragments and conjugates thereof can be administered by slow infusion, rather than in an intravenous push or bolus. In one example, a higher loading dose is administered, with subsequent, maintenance doses being administered at a lower level. For example, an initial loading dose of 4 mg/kg antibody or antigen binding fragment (or the corresponding dose of a conjugate including the antibody or antigen binding fragment) may be infused over a period of some 90 minutes, followed by weekly maintenance doses for 4-8 weeks of 2 mg/kg infused over a 30 minute period if the previous dose was well tolerated. 
     Controlled release parenteral formulations can be made as implants, oily injections, or as particulate systems. For a broad overview of protein delivery systems see, Banga, A. J.,  Therapeutic Peptides and Proteins: Formulation, Processing, and Delivery Systems , Technomic Publishing Company, Inc., Lancaster, Pa., (1995). Particulate systems include microspheres, microparticles, microcapsules, nanocapsules, nanospheres, and nanoparticles. Microcapsules contain the therapeutic protein, such as a cytotoxin or a drug, as a central core. In microspheres, the therapeutic is dispersed throughout the particle. Particles, microspheres, and microcapsules smaller than about 1 μm are generally referred to as nanoparticles, nanospheres, and nanocapsules, respectively. Capillaries have a diameter of approximately 5 μm so that only nanoparticles are administered intravenously. Microparticles are typically around 100 μm in diameter and are administered subcutaneously or intramuscularly. See, for example, Kreuter, J.,  Colloidal Drug Delivery Systems , J. Kreuter, ed., Marcel Dekker, Inc., New York, N.Y., pp. 219-342 (1994); and Tice &amp; Tabibi,  Treatise on Controlled Drug Delivery , A. Kydonieus, ed., Marcel Dekker, Inc. New York, N.Y., pp. 315-339, (1992). 
     Polymers can be used for ion-controlled release of the CARs, or T cells expressing a CAR, antibody or antigen binding fragment or conjugate compositions disclosed herein. Various degradable and nondegradable polymeric matrices for use in controlled drug delivery are known in the art (Langer,  Accounts Chem. Res.  26:537-542, 1993). For example, the block copolymer, polaxamer 407, exists as a viscous yet mobile liquid at low temperatures but forms a semisolid gel at body temperature. It has been shown to be an effective vehicle for formulation and sustained delivery of recombinant interleukin-2 and urease (Johnston et al.,  Pharm. Res.  9:425-434, 1992; and Pec et al.,  J. Parent. Sci. Tech.  44(2):58-65, 1990). Alternatively, hydroxyapatite has been used as a microcarrier for controlled release of proteins (Ijntema et al.,  Int. J. Pharm.  112:215-224, 1994).

     Example 1A 
     Isolation of CD19-Specific Antibodies from a Fully Human Phage and Yeast-Displayed ScFv Library 
     Materials and Methods: 
     a) Production of Human ScFv and CD19-Specific Antibodies 
     A naïve human ScFv (recombinant single chain fragment variable of immunoglobulin) phage display library (approximate diversity, 10 10  unique specificities), constructed from peripheral blood B cells of 50 healthy donors (Z. Y. Zhu and D. S. Dimitrov, unpublished data), were used for selection of ScFvs for recombinant human CD19 protein (Miltenyi Biotec, unpublished). Amplified libraries of 10 12  phage-displayed ScFv were incubated with 5, 3, and 1, μg of coated CD19 in a 5×100-μl volume, distributed equally in 5 wells of a 96-well plate for 2 h at room temperature during the first, second and third rounds of biopanning, respectively. After each round of incubation the wells were washed 5 times for the first round and 10 times for the later rounds with phosphate-buffered saline containing 0.05% Tween 20 (PBST) to remove nonspecifically bound phage, the bound phage were mixed with TG1 competent cells for 1 hour at 37° C., and the phage was amplified from the infected cells and used in the next round of biopanning. After the third round of biopanning, 380 clones were randomly picked from the infected TG1 cells and each inoculated into 150 μl 2YT medium containing 100 μg/ml carbenicillin and 0.2% glucose in 96-well plates by using the automated BioRobotics BioPick colony picking system (Genomic Solutions, Ann Arbor, Mich.). After the bacterial cultures reached an optical density at 600 nm (OD600) of 0.5, helper phage M13K07 at a multiplicity of infection (MOI) of 10 and kanamycin at 50 μg/ml (final concentration) were added to the medium, and the plates were further incubated at 30° C. overnight in a shaker at 250 rpm. The phage supernatants were mixed with 3% nonfat milk in PBS at a 4:1 volume ratio and used for enzyme-linked immunosorbent assay (ELISA) to identify clones of phage displaying ScFvs or VHs with high CD19 binding affinity. The supernatants were incubated for 2 h at room temperature with recombinant human CD19 coated at 50 ng per well in 96-well plates and washed five times with PBST, (after overnight incubation at 4° C. it was blocked with 3% nonfat milk in PBS and washed three times with PBS containing 0.05% Tween 20.) CD19-bound phage were detected using horseradish peroxidase-conjugated goat anti-M13 antibody. After incubation with the antibody, the nonspecifically bound antibody was removed by washing wells, and the 3,3,′5,5′-tetramethylbenzidine (TMB) substrate was added, and solution absorbance at 450 nm (A450) measured. Clones that bound to CD19 with A450 of &gt;1.0 were selected for further characterization. 
     b) Expression and Purification of Selected Soluble ScFvs. 
     The VH and VL of the selected clones were DNA sequenced, and the ScFvs encoded by clones with unique sequences were expressed and purified as described below. Plasmids extracted from these clones were used for transformation of HB2151 cells. A single colony was picked from the plate containing freshly transformed cells, inoculated into 200 ml 2YT medium containing 100 μg/ml ampicillin and 0.2% glucose, and incubated at 37° C. with shaking at 250 rpm. When the culture OD at 600 nm reached 0.90, isopropyl-β-d-thiogalactopyranoside at a 0.5 mM final concentration was added, and the culture was further incubated overnight at 30° C. The bacterial pellet was collected after centrifugation at 8,000×g for 20 min and resuspended in PBS buffer containing 0.5 mU polymixin B (Sigma-Aldrich, St. Louis, Mo.). After 30 min incubation with rotation at 50 rpm at room temperature, the resuspended pellet was centrifuged at 25,000×g for 25 min at 4° C., and the supernatant was used for ScFv purification using the Ni-NTA resin following vendor protocol (Qiagen). 
     c) ELISA Binding Assay 
     ELISA binding assay 50 μl of the diluted recombinant human CD19 in PBS at 2 ug/ml was coated in a 96-well plate at 4° C. overnight. Purified ScFv with His and Flag tags were serially diluted and added into the target protein coated wells. After washing, a 1:3000 diluted HRP conjugated anti-Flag antibody was added for 1 hr at RT. After washing, 3, 3, 5, 5′-Tetramethylbenzidine (TMB) substrate was added, 1N H2504 was added to stop the reaction after incubation at room temperature for 10 minutes, and the O.D. was read at 450 nm to quantify the relative ability of ScFv to bind CD19. 
     d) Yeast Display of scFv Library. 
     The same ScFv starting material as for phage display was also incorporated into a yeast ScFv display system. To supplement phage-based scFv analysis, yeast libraries expressing the human scFv library were also screened. To enrich the yeast expressing scFvs that bind to both the recombinant CD19-Fc and the CD19 expressed on the cell surface of the CHOK1 cells, cell panning on CHOK1 transfected with CD19 cells was performed. For the first round of panning on the cell surface, two days prior to panning, the CHOK1-CD19 cells were seeded into 6-well plates and grown to 50% confluency in F12 K medium. 5×10 7  yeast cells were then washed 2× with PBSA buffer and resuspended into 3 mL F12 K medium, and then gently added dropwise to the CHOK1-CD19 cells. After rocking gently on ice for 2 hours, the CHOK1-CD19 cells were then washed 3 times with ice-cold PBSA to remove the yeast cells that did not bind to the CHOK1-CD19, and 0.05% Trypsin-EDTA (Gibco) was then used to dissociate the CHOK1-CD19 cells and bound yeast cells from the plate. The cell mix containing both the yeast and CHOK1 cells were then inoculated into 10 mL SDCAA medium and amplified overnight at 30° C. and then induced in SGCAA medium at 30° C. for 16 hours. For the second round of cell panning, a similar protocol as above was performed, but more stringent wash conditions were used. This method of panning yielded the m19217 binder. Further characterization of this binder as well as others from phage display indicated that affinity maturation was required, as the biological characteristics of the CAR created from this hit were still not optimal. 
     To increase the affinity of m19217, a yeast-display m19217 mutant scFv library was created by using error-prone PCR to create random point mutations in scFv gene sequences. After electroporation, the resulting mutant library was then grown overnight at 30° C. for 16 hours in SDCAA medium and then switched into SGCAA medium at 30° C. for another 16 hours. The mutant library was then sorted through MACS (immunomagnetic column, Miltenyi Biotec) with CD19-Fc as the capture antigen to downsize the library and to increase the population of mutants that could bind to CD19-Fc. The strongest binders were then selected by double staining the pools with Anti-c-Myc-Alexa 488 and CD19-Fc/Anti-Hu-Fc and selecting for the binders that had the highest binding affinities as well as c-Myc expression levels. This process was then repeated two more times, until flow cytometry of yeast particles with fluorescently tagged antigen yielded average binding affinities of the mutant pools that were increased over the starting construct. Binding affinities were estimated by flow cytometry of yeast pools using decreasing amounts of labeled CD19. This process resulted in an increase of EC50 (Effective concentration for 50% binding of labeled CD19 on yeast displaying ScFv) for M19217 of 0.5 ug/ml to an affinity of &lt;0.01 ug/ml for the affinity matured binders (M19217-1, 19217-2, M19217-7, M19217-23, M19217-29, M19217-38, M19217-40). 
     Results: 
     Due to the unique challenges of CD19 structure, phage display candidates did not yield biologically functional CAR constructs and thus ScFv identification that yielded biologically active binders were generated by yeast display. Based upon flow cytometry analysis of yeast-displayed ScFv, eight ScFv clones specific for recombinant human CD19 were identified and labeled as human anti-CD19 ScFv binders M19217 (LTG2050, founder clone, EC50 of 0.5 ug/ml), and the following affinity matured binders (EC50&lt;0.01 ug/ml): M19217-1 (LTG2065), M19217-2 (LTG2066), M19217-7 (LTG2067), M19217-23 (LTG2068), M19217-29 (LTG2069), M19217-38 (LTG2070), and M19217-40 (LTG2071) respectively. The generation of a tandem CAR incorporating the anti-CD19 scFv M19217-1 sequence, is outlined in EXAMPLE 2, infra.

     Isolation of CD22-Specific Antibodies from a Fully Human Phage and Yeast-Displayed ScFv Library 
     Materials and Methods: 
     a) Production of Human ScFv and CD22-Specific Antibodies 
     A naïve human ScFv (recombinant single chain fragment variable of immunoglobulin) phage display library (approximate diversity, 10 10  unique specificities), constructed from peripheral blood B cells of 50 healthy donors (Z. Y. Zhu and D. S. Dimitrov, unpublished data), were used for selection of ScFvs for recombinant human CD19 protein (Miltenyi Biotec, unpublished). Amplified libraries of 10 12  phage-displayed ScFv were incubated with 5, 3, and 1, μg of coated CD22 in a 5×100-μl volume, distributed equally in 5 wells of a 96-well plate for 2 h at room temperature during the first, second and third rounds of biopanning, respectively. After each round of incubation the wells were washed 5 times for the first round and 10 times for the later rounds with phosphate-buffered saline containing 0.05% Tween 20 (PBST) to remove nonspecifically bound phage, the bound phage were mixed with TG1 competent cells for 1 hour at 37° C., and the phage was amplified from the infected cells and used in the next round of biopanning.

After the bacterial cultures reached an optical density at 600 nm (OD600) of 0.5, helper phage M13K07 at a multiplicity of infection (MOI) of 10 and kanamycin at 50 μg/ml (final concentration) were added to the medium, and the plates were further incubated at 30° C. overnight in a shaker at 250 rpm. The phage supernatants were mixed with 3% nonfat milk in PBS at a 4:1 volume ratio and used for enzyme-linked immunosorbent assay (ELISA) to identify clones of phage displaying ScFvs or VHs with high CD22 binding affinity. The supernatants were incubated for 2 h at room temperature with recombinant human CD22 coated at 50 ng per well in 96-well plates and washed five times with PBST, (after overnight incubation at 4° C. it was blocked with 3% nonfat milk in PBS and washed three times with PBS containing 0.05% Tween 20.) CD22-bound phage were detected using horseradish peroxidase-conjugated goat anti-M13 antibody. After incubation with the antibody, the nonspecifically bound antibody was removed by washing wells, and the 3,3,′5,5′-tetramethylbenzidine (TMB) substrate was added, and solution absorbance at 450 nm (A450) measured. Clones that bound to CD22 with A450 of &gt;1.0 were selected for further characterization. 
     b) Expression and Purification of Selected Soluble ScFvs 
     The VH and VL of the selected clones were DNA sequenced, and the ScFvs encoded by clones with unique sequences were expressed and purified as described below. Plasmids extracted from these clones were used for transformation of HB2151 cells. A single colony was picked from the plate containing freshly transformed cells, inoculated into 200 ml 2YT medium containing 100 μg/ml ampicillin and 0.2% glucose, and incubated at 37° C. with shaking at 250 rpm. When the culture OD at 600 nm reached 0.90, isopropyl-β-d-thiogalactopyranoside at a 0.5 mM final concentration was added, and the culture was further incubated overnight at 30° C. The bacterial pellet was collected after centrifugation at 8,000×g for 20 min and resuspended in PBS buffer containing 0.5 mU polymixin B (Sigma-Aldrich, St. Louis, Mo.). After 30 min incubation with rotation at 50 rpm at room temperature, the resuspended pellet was centrifuged at 25,000×g for 25 min at 4° C., and the supernatant was used for ScFv purification using the Ni-NTA resin following vendor protocol (Qiagen). 
     c) ELISA Binding Assay 
     For ELISA analysis 50 μl of the diluted recombinant human CD22 in PBS at 2 ug/ml was coated in a 96-well plate at 4° C. overnight. Purified ScFv with His and Flag tags were serially diluted and added into the target protein coated wells. After washing, a 1:3000 diluted HRP conjugated anti-Flag antibody was added for 1 hr at RT. After washing, 3, 3, 5, 5′-Tetramethylbenzidine (TMB) substrate was added, 1N H 2 SO 4  was added to stop the reaction after incubation at room temperature for 10 minutes, and the O.D. was read at 450 nm to quantify the relative ability of ScFv to bind CD22. 
     d) Yeast Display of scFv Library 
     The same ScFv starting material as for phage display was also incorporated into a yeast ScFv display system. To supplement phage-based scFv analysis, yeast libraries expressing the human scFv library were also screened. To enrich the yeast expressing scFvs that bind to both the recombinant CD22-Fc and the CD19 expressed on the cell surface of the CHOK1 cells, cell panning on CHOK1 transfected with CD22 cells was performed. For the first round of panning on the cell surface, two days prior to panning, the CHOK1-CD22 cells were seeded into 6-well plates and grown to 50% confluency in F12 K medium. 5×10 7  yeast cells were then washed 2× with PBSA buffer and resuspended into 3 mL F12 K medium, and then gently added dropwise to the CHOK1-CD22 cells. After rocking gently on ice for 2 hours, the CHOK1-CD22 cells were then washed 3 times with ice-cold PBSA to remove the yeast cells that did not bind to the CHOK1-CD22, and 0.05% Trypsin-EDTA (Gibco) was then used to dissociate the CHOK1-CD22 cells and bound yeast cells from the plate. The cell mix containing both the yeast and CHOK1 cells were then inoculated into 10 mL SDCAA medium and amplified overnight at 30° C. and then induced in SGCAA medium at 30° C. for 16 hours. For the second round of cell panning, a similar protocol as above was performed, but more stringent wash conditions were used. This method of panning yielded the 16P, 24P, 25P, 11S and 12S binders. Binder sequences were incorporated into CART constructs as described in Example 2, infra, in a series of in vitro CART functional assays. Characterization of these binders from phage display in CART format revealed that only 16P binder had specific tumor-lytic activity in vitro, but it was low as compared to CAR positive control. Further, when 16P-based CART cells were tested in in vivo xenograft model, its antitumor function was very weak (Example 2, infra). Taken together, these results indicated that affinity maturation of anti-CD22 ScFv binders was required, as the biological characteristics of the CAR created from this binder set were still not optimal. 
     To increase the affinity of 16P, a yeast-display mutant scFv library was created by using error-prone PCR to create random point mutations in scFv gene sequences. After electroporation, the resulting mutant library was then grown overnight at 30° C. for 16 hours in SDCAA medium and then switched into SGCAA medium at 30° C. for another 16 hours. The mutant library was then sorted through MACS (immunomagnetic column, Miltenyi Biotec) with CD22-Fc as the capture antigen to downsize the library and to increase the population of mutants that could bind to CD22-Fc. The strongest binders were then selected by double staining the pools with Anti-c-Myc-Alexa 488 and CD19-Fc/Anti-Hu-Fc and selecting for the binders that had the highest binding affinities as well as c-Myc expression levels. This process was then repeated two more times, until flow cytometry of yeast particles with fluorescently tagged antigen yielded average binding affinities of the mutant pools that were increased over the starting construct. Binding affinities were estimated by flow cytometry of yeast pools using decreasing amounts of labeled CD22. This process resulted in an increase of EC50 (Effective concentration for 50% binding of labeled CD19 on yeast displaying ScFv) for 16P of 0.5 ug/ml to an affinity of &lt;0.01 ug/ml for the affinity matured binders (16P1, 16P2, 16P3, 16P3v2, 16P6, 16P8, 16P10, 16P13, 16P15, 16P16, 16P17, 16P20, 16P20v2). 
     Results: 
     Due to the unique challenges of CD22 structure, phage display candidates did not yield sufficient functional CAR constructs with high biological activity and specificity. Thus, ScFv for biologically active and highly specific binders were generated by yeast display. Based upon flow cytometry analysis of yeast-displayed ScFv, thirteen ScFv clones specific for recombinant human CD22 were identified and labeled as human anti-CD22 ScFv binders 16P (LTG2202, founder clone, EC50 of 0.5 ug/ml), and the following affinity matured binders (EC50&lt;0.01 ug/ml): 16P1, 16P2, 16P3, 16P3v2, 16P6, 16P8, 16P10, 16P13, 16P15, 16P17, 16P20, and 16P20v2 respectively. The generation of a tandem CAR incorporating the anti-CD22 scFv 16P17 sequence is outlined in EXAMPLE 2, infra. 
     Example 2 
     Dual-Targeting Tandem CARs Expressing Fully Human Anti-CD22 and Anti CD19 scFv Binding Sequences 
     This example discusses the creation of a dual-targeting CAR, which targets tumor antigens CD19 and CD22 simultaneously. This approach has been postulated to help mitigate tumor antigen escape, which accounts for a significant portion of CAR therapy failures using single CAR approaches, namely anti-CD19 CAR, or anti-CD22 CAR therapy (Sotillo, Elena, et al. “Convergence of acquired mutations and alternative splicing of CD19 enables resistance to CART-19 immunotherapy.”  Cancer discovery  (2015). Gardner, Rebecca, et al. “Acquisition of a CD19 negative myeloid phenotype allows immune escape of MLL-rearranged B-ALL from CD19 CAR-T cell therapy.”  Blood  (2016): blood-2015., Fry, Terry J., et al. “CD22-targeted CAR T cells induce remission in B-ALL that is naive or resistant to CD19-targeted CAR immunotherapy.”  Nature medicine  24.1 (2018): 20). 
     Utilization of mouse scFv sequences as CAR components has been shown to cause immune rejection or allergic anaphylactic reactions in patients, thus limiting the persistence and utility of CAR T treatment, and increasing the risk of toxicity. Therefore, utilization of fully human scFv binder sequences in CAR design is a high priority for future CAR development. 
     CD19 is a 85-95 kDa transmembrane cell surface glycoprotein receptor. CD19 is a member of immunoglobulin (Ig) superfamily of proteins, and contains two extracellular Ig-like domains, a transmembrane, and an intracellular signaling domain (Tedder T F, Isaacs, C M, 1989 , J Immunol  143:712-171). CD19 modifies B cell receptor signaling, lowering the triggering threshold for the B cell receptor for antigen (Carter, R H, and Fearon, D T, 1992, Science, 256:105-107), and co-ordinates with CD81 and CD21 to regulate this essential B cell signaling complex (Bradbury, L E, Kansas G S, Levy S, Evans R L, Tedder T F, 1992, J Immunol, 149:2841-50). During B cell ontogeny CD19 is able to signal at the pro-B, pre-pre-B cell, pre-B, early B cell stages independent of antigen receptor, and is associated with Src family protein tyrosine kinases, is tyrosine phosphorylated, inducing both intracellular calcium mobilization and inositol phospholipid signaling (Uckun F M, Burkhardt A L, Jarvis L, Jun X, Stealy B, Dibirdik I, Myers D E, Tuel-Ahlgren L, Bolen J B, 1983, J Biol Chem 268:21172-84). The key point of relevance for treatment of B cell malignancies is that CD19 is expressed in a tightly regulated manner on normal B cells, being restricted to early B cell precursors at the stage of IgH gene rearrangement, mature B cells, but not expressed on hematopoietic stem cells, or mature plasma cells (Anderson, K C, Bates, M P, Slaughenhout B L, Pinkus G S, Schlossman S F, Nadler L M, 1984, Blood 63:1424-1433). 
       Homo sapiens  CD22 (SIGLEC-2, Leu14) is a well-investigated cell surface glycoprotein expressed on B cell leukemias and lymphomas. At least two anti-CD22 antibody drug (Inotuzumab Ozogamicin) or immunotoxin conjugates (Moxetumomab Pasudotox) have been the subject of clinical trials (NCT02981628, NCT00659425). These approaches have had some success, and are still being investigated, for example in combination with other chemotherapeutic agents (Muller F, Stookey S, Cunningham T, Pastan I, 2017, Paclitaxel synergizes with exposure tume adjusted CD22-targeted immunotoxins against B-cell malignancies, Oncotarget 8:30644-30655). However, given the current advances with T-cell based therapy with CD19 CARs, the best approach to targeting CD22-expressing malignancies may be cell-based immunotherapy. Therapy featuring the m971-based anti-CD22 CAR is currently undergoing clinical trial at the National Cancer Institute (NCT02315612, P.I.: Terry Fry, M.D.). The tandem CD22 CD19-targeting CAR constructs presented here are an innovative new approach to creating and implementing new, fully human CD19 and CD22 binding moieties in one construct in order to achieve complete durable remissions and prevent tumor antigen escape. 
     Single CAR controls have been employed in this example as a comparison to the tandem CARs targeting CD19 and CD22. CAR Construct LTG1538 utilizing the mouse hybridoma FMC63-derived scFv is an activity control. This mouse-derived sequence is the current binder employed in commercial development (See KTE-C19, Kite Pharma, and CTL019, Novartis). The m971 CAR LTG2200 is equivalent to the CAR being evaluated at the NCI, and is used as an anti-CD22 CAR control. 
     Materials and Methods: 
     (a) Cell Lines 
     The Burkitt lymphoma cell line Raji, and the chronic myelogenous leukemia line K562 were purchased from American Tissue Culture Collection (ATCC, Manassass, Va.). The REH leukemia line was purchased from DSMZ (Leibniz Institute DSMZ, Braunschwieg, Germany). Cells were cultured in RPMI-1640 medium supplemented with 10% heat-inactivated fetal bovine serum (FBS, Hyclone, Logan, Utah) and 2 mM L-Glutamax (Thermo Fisher Scientific, Grand Island, N.Y.). Human Embryonic kidney line 293T was purchased from ATCC (Gibco/Thermo Fisher Scientific, Grand Island, N.Y.). Single-cell clones of luciferase-expressing cell lines were generated by stably transducing wild-type tumor lines with lentiviral vector encoding firefly luciferase (Lentigen Technology, Inc., Gaithersburg, Md.), followed by cloning and selection of luciferase-positive clones. The Raji clone was generated by passaging luciferase-transduced Raji cells in the mice and was selected for its proliferative capacity. Whole blood was collected from healthy volunteers at Oklahoma Blood Institute (OBI) with donors&#39; written consent. Processed buffy coats were purchased from OBI (Oklahoma City, Okla.). The CD4-positive and CD8-positive human T cells were purified from buffy coats via positive selection using a 1:1 mixture of CD4- and CD8-MicroBeads (Miltenyi Biotec, Bergisch Gladbach, Germany) according to manufacturer&#39;s protocol. 
     (b) Creation of Chimeric Antigen Receptor (CAR)—Expression Vectors 
     CAR antigen-binding domains, ScFv, sequences were derived from human anti-CD22 ScFv or heavy chain variable fragments. CAR T constructs were generated by linking the binder sequence in frame to CD8a linking and transmembrane domains (aa 123-191, Ref sequence ID NP_001759.3), and then to 4-1BB (CD137, aa 214-255, UniProt sequence ID Q07011) signaling domain and CD3 zeta signaling domain (CD247, aa 52-163, Ref sequence ID: NP_000725.1). CAR constructs sequences were cloned into a third generation lentiviral plasmid backbone (Lentigen Technology Inc., Gaithersburg, Md.). Lentiviral vector (LV) containing supernatants were generated by transient transfection of HEK 293T cells and vector pelleted by centrifugation of lentiviral vector-containing supernatants, and stored at −80° C. 
     (c) Primary T Cell Purification and Transduction 
     Human primary T cells from healthy volunteers were purified from whole blood or buffy coats (purchased from commercial provider with donor&#39;s written consent) using immunomagnetic bead selection of CD4 +  and CD8 +  cells according to manufacturer&#39;s protocol (Miltenyi Biotec, Bergisch Gladbach, Germany). T cells were cultivated in TexMACS medium supplemented with 200 IU/ml IL-2 at a density of 0.3 to 2×10 6  cells/ml, activated with CD3/CD28 MACS® GMP T Cell TransAct reagent (Miltenyi Biotec) and transduced on day 2 with lentiviral vectors encoding CAR constructs in the presence of 10 ug/ml protamine sulfate (Sigma-Aldrich, St. Louis, Mo.) overnight, and media exchanged on day 3. Cultures were propagated in TexMACS medium supplemented with 200 IU/ml IL-2 until harvest on day 8-13. 
     (d) Immune Effector Assays (CTL and Cytokine) 
     To determine cell-mediated cytotoxicity (CTL assay), 5,000 target cells stably transduced with firefly luciferase were combined with CAR T cells at various effector to target ratios and incubated overnight. SteadyGlo reagent (Promega, Madison Wis.) was added to each well and the resulting luminescence quantified as counts per second (sample CPS). Target only wells (max CPS) and target only wells plus 1% Tween-20 (min CPS) were used to determine assay range. Percent specific lysis was calculated as: (1-(sample CPS-min CPS)/(max CPS-min CPS)). Supernatants from co-cultures at E:T ratio of 10:1 were removed and analyzed by ELISA (eBioscience, San Diego, Calif.) for IFNγ, TNFα and IL-2 concentration. 
     (e) Flow Cytometric Analysis 
     For cell staining, half a million CAR T transduced cells were harvested from culture, washed two times in cold AutoMACS buffer supplemented with 0.5% bovine serum albumin (Miltenyi Biotec), and CAR surface expression detected by staining with CD22-Fc peptide followed by anti Fc-PE conjugate (Jackson ImmunoResearch, West Grove, Pa.). Anti-CD4 antibody conjugated to VioBlue fluorophore (Miltenyi Biotec) was used where indicated, as per vendors&#39; protocol. Non-transduced cells were used as negative controls. Dead cells in all studies were excluded by 7AAD staining (BD Biosciences, San Jose, Calif.). Cells were washed twice and resuspended in 200 ul Staining Buffer before quantitative analysis by flow cytometry. Flow cytometric analysis was performed on a MACSQuant®10 Analyzer (Miltenyi Biotec), and data plots were generated using FlowJo software (Ashland, Oreg.). 
     Results 
     Tandem CAR constructs for dual targeting of CD22 and CD19 tumor antigens were developed in order to overcome tumor antigen escape. Shema of tandem CAR design is shown in  FIGS. 1A and 1B . Fully human scFv binders targeting CD19 and CD22 were connected in tandem by a flexible linker, in either 22-19 or 19-22 orientation, noted membrane distal to proximal. Then, the resulting CAR binding segment was linked in frame to CD8 hinge and transmembrane domain, 4-1BB costimulatory domain and CD3 zeta activation domain to generate CAR 22-19 (LTG2681,  FIG. 1A ), or CAR19-22 (LTG2719,  FIG. 1B ). CAR sequences were incorporated into a 3rd generation lentiviral vectors and applied to primary human T cells for transduction. 
     Single CAR controls have been employed in this example as a comparison to the tandem CARs targeting CD19 and CD22. CAR Construct LTG1538 utilizing the mouse hybridoma FMC63-derived scFv is an activity control. This mouse-derived sequence is the current binder employed in commercial development (See KTE-C19, Kite Pharma, and CTL019, Novartis). The m971 CAR LTG2200 is equivalent to the CAR being evaluated at the NCI, and is used as an anti-CD22 CAR control. 
     The surface expression of anti-CD19/CD22 CARs incorporating single chain fragment variable (ScFv) sequences reactive with CD19/CD22 antigen, is shown in  FIG. 2 . The expression level for each ScFv-containing CAR was determined by flow cytometric analysis of LV-transduced T cells from healthy donors using one of two detection methods: i) CD22-his, followed anti-his-PE; ii) CD19 Fc recombinant protein, followed by anti Fc-A647. The ScFv-based anti-CD19/CD22 CAR constructs CAR22-19 LTG 2681, and CAR19-22 LTG2719, were highly expressed in human primary T cells as compared to non-transduced T cell controls. 
     As shown in  FIG. 3 , high cytolytic activity of the CD19/CD22 CARs was demonstrated: Human primary T cells were transduced with LV encoding CAR constructs (CAR 22-19 (LTG2681, D0023), CAR19-22 (LTG 2791, D0024), CAR19 (LTG1538), or CAR22 (LTG2200) see Methods), then incubated for 18 hours with the Raji, REH, or 293T cell lines, stably transduced with firefly luciferase, for luminescence based in vitro killing assays. Raji and Reh leukemia lines express CD19 and CD22 on their surface, while the negative controls, 293T do not. Raji and REH cells were lysed effectively by the tandem CAR 22-19 (LTG2681), tandem CAR19-22 (LTG27190), and the single-targeting controls CAR19 (LTG1538) and CAR22 (LTG2200), ( FIG. 3 ). Therefore, both tandem CAR22-19 and CAR19-22 were functional in tumor lines co-expressing the CD19 and CD22 antigens, and had no spontaneous killing activity against CD19-CD22-cell line 293T, underscoring target specificity of these constructs. 
     Next, the functionality and specificity of each scFv in a tandem CAR in isolation was tested by using tumor lines A431 or 293T, engineered to express only a single target antigen (CD19 or CD22, or irrelevant antigen CD20). 293T-luc lines were created that express CD19 (293T luc CD-19+), or CD22 (293T luc-20+), and line CD20+(293T luc CD20) was used as an irrelevant target control ( FIG. 4A ). 293T-19+ were lysed by the CAR 19 (LTG1538) and tandem CAR 22-19 (LTG 2681), but not by CAR22 LTG 2200 or untransduced T cells control ( FIG. 3 ). 293T-CD22+ were lysed by the tandem CAR 22-19 (LTG 2681) and the single CAR20 LTG2200, but not by the single CAR19 (LTG 1538), or untransduced control, demonstrating antigen specificity of the tandem CAR. Finally, no CAR construct lysed the 293T luc CD20 cells, since this antigen was not targeted ( FIG. 4A ). Similarly, tandem CAR T cells were tested in an overnight killing assay against A431 clones expressing only CD19 antigen (A431 luc CD19), or only CD22 antigen (A431 luc-CD22), or an irrelevant target control line A431 luc-CD20, expressing the antigen CD20, which the tandem CARs 19-22 and 22-19 are not intended to recognize ( FIG. 4B ). Again, A431 luc CD19 line was lysed only by the CAR 19 (LTG1538) and tandem CAR 22-19 (LTG 2681), but not by CAR22 LTG 2200 or untransduced T cells control, whereas line A431 luc CD22 was lysed by the tandem CAR 22-19 (LTG 2681) and the single CAR20 LTG2200, but not by the single CAR19 (LTG 1538), or untransduced control, demonstrating antigen specificity of the tandem CAR. Moreover, no CAR construct lysed A431 luc CD20 cells, since this antigen was not targeted ( FIG. 4B ). This results underscores the independent functionality and specificity of each targeting domain of the tandem CAR22-19 ( FIGS. 4A-4B ), and the potential of tandem CARs targeting the CD19 and CD22 antigens to mitigate tumor antigen escape. 
     The capacity of anti-CD19/CD22 CAR T cells for cytokine secretion was then evaluated ( FIG. 5 ). The CD19+CD22+ Raji tumor cells were co-incubated with the tandem 22-19 CAR T cells (LTG2681) or positive control CAR19 (LTG1538), positive control CAR22 (LTG2200), or negative control untransduced T cells (UTD) at effector to target ratio of 10:1 overnight, and culture supernatants were analyzed by ELISA for IFN gamma, TNF alpha, and IL-2. The tandem CAR 22-19 (LTG2681) strongly induced cytokines in response to tumor cells, whereas the negative control (untransduced, UTD.) yielded no appreciable cytokine induction. Notably, tandem CAR T-expressing cells LTG2681 showed similar levels of IFN gamma, TNF alpha, IL-2, to CAR22 control (LTG2200), and somewhat higher cytokine response than the single CAR19 (LTG1538) control, demonstrating the high potency of the tandem CAR. Importantly, CAR 22-19 produced no cytokine secretion in the absence of tumor cells (CART alone group), which further confirms CAR specificity, and indicates a lack of tonic signaling by the tandem car. 
     Example 3 
     Dual-Targeting CAR 22-19 Constructs Incorporating Various Co-Stimulatory Domains Demonstrate Robust Anti-Tumor Function 
     This Example discusses tandem CD22- and CD19-dual targeting CAR constructs, which are incorporating various co-stimulatory domains. The co-stimulatory domains utilized in CAR 22-19 design in this example included ICOS, OX40, CD27, CD137/4-1BB, and CD28. These co-stimulatory domain sequences are derived from T cell surface molecules known to be involved in positive regulation of T cell function, including T cell activation, expansion, persistence, phenotypic differentiation, memory formation, and anti-tumor responses (Zhao Z, Condomines M, van der Stegen S J, et al: Structural design of engineered costimulation determines tumor rejection kinetics and persistence of CART cells. Cancer cell 28:415-428, 2015, Guedan S, Posey A D, Jr., Shaw C, et al: Enhancing CAR T cell persistence through ICOS and 4-1BB costimulation. JCI Insight 3, 2018, Song D-G, Ye Q, Poussin M, et al: CD27 costimulation augments the survival and antitumor activity of redirected human T cells in vivo. Blood 119:696-706, 2012, Hombach A A, Heiders J, Foppe M, et al: OX40 costimulation by a chimeric antigen receptor abrogates CD28 and IL-2 induced IL-10 secretion by redirected CD4+ T cells. Oncoimmunology 1:458-466, 2012, Yoshinaga S K, Whoriskey J S, Khare S D, et al: T-cell co-stimulation through B7RP-1 and ICOS. Nature 402:827-832, 1999). In some cases, CAR linker/hinge regions were also derived from the co-stimulatory domains utilized. 
     Concurrent dual targeting of CD19 and CD22 antigens is designed to mitigate tumor antigen escape, which has hindered therapeutic benefit in a sub-population of patients who have received either CD19 or CD22-targeted single CAR therapy (Sotillo, Elena, et al. “Convergence of acquired mutations and alternative splicing of CD19 enables resistance to CART-19 immunotherapy.”  Cancer discovery  (2015). Gardner, Rebecca, et al. “Acquisition of a CD19 negative myeloid phenotype allows immune escape of MLL-rearranged B-ALL from CD19 CAR-T cell therapy.”  Blood  (2016): blood-2015., Fry, Terry J., et al. “CD22-targeted CAR T cells induce remission in B-ALL that is naive or resistant to CD19-targeted CAR immunotherapy.”  Nature medicine  24.1 (2018): 20). 
     Avoiding sequences of non-human origin, which may trigger host anti-“foreign” immune response, in CAR design, is thought to contribute to improved persistence of CAR T cells, and is preferred. All CAR components utilized in this example were of human origin. CAR binder configuration based on anti-CD 22-19 CAR (LTG2737), comprised of T cell membrane-distal human scFv targeting CD22 linked in frame to the T cell membrane-proximal human scFv targeting CD19, was utilized in all CAR constructs in Example 3. 
     Materials and Methods: 
     (a) Cell Lines 
     The Burkitt lymphoma cell line Raji, was purchased from American Tissue Culture Collection (ATCC, Manassass, Va.). Cells were cultured in RPMI-1640 medium supplemented with 10% heat-inactivated fetal bovine serum (FBS, Hyclone, Logan, Utah) and 2 mM L-Glutamax (Thermo Fisher Scientific, Grand Island, N.Y.). Human Embryonic kidney line 293T was purchased from ATCC (Gibco/Thermo Fisher Scientific, Grand Island, N.Y.). Single-cell clones of luciferase-expressing cell lines were generated by stably transducing wild-type tumor lines with lentiviral vector encoding firefly luciferase (Lentigen Technology, Inc., Gaithersburg, Md.), followed by cloning and selection of luciferase-positive clones. CD19 and CD22 expressing 293T cell line clones, designated 293TCD19 and 293TCD22, respectively, were generated by lentiviral transduction of human CD19 protein and human CD22 proteins into the parental 293T-luciferase expressing clone, following by single-cell cloning, selection and expansion of CD19- or CD22-positive target cell clones, as appropriate. Stable luciferase-expressing Raji clone was generated by passaging luciferase-transduced Raji cells in the mice and was selected for its proliferative capacity. Whole blood was collected from healthy volunteers at Oklahoma Blood Institute (OBI) with donors&#39; written consent. Processed buffy coats were purchased from OBI (Oklahoma City, Okla.). The CD4-positive and CD8-positive human T cells were purified from buffy coats via positive selection using a 1:1 mixture of CD4- and CD8-MicroBeads (Miltenyi Biotec, Bergisch Gladbach, Germany) according to manufacturer&#39;s protocol. 
     (b) Creation of Chimeric Antigen Receptor (CAR)—Expression Vectors 
     The tandem CAR antigen-binding domain, was derived from a human anti-CD22 ScFv and human anti-CD19 scFv sequences, linked in tandem, in configuration anti-CD22 scFv-anti CD19-scFv-hinge-transmembrane domain-endodomain. Some CAR T constructs were generated by linking the CAR antigen-binding domain in frame to CD8a hinge and transmembrane domains (aa 123-191, Ref sequence ID NP_001759.3), and then to 4-1BB (CD137, aa 214-255, UniProt sequence ID Q07011) signaling domain and CD3 zeta signaling domain (CD247, aa 52-163, Ref sequence ID: NP_000725.1). In other constructs, the 4-1BB co-stimulatory domain was substituted for the human ICOS, CD27, CD28, OX-40 co-stimulatory domain, using the full signaling domain sequence of each molecule. In some embodiments, the CD8 transmembrane domain was substituted by transmembrane sequence derived from same protein as the co-stimulatory domain. In some embodiments, the endodomain of the CAR comprised two co-stimulatory domains connected in tandem. In some embodiments, no co-stimulatory domain was used, and the CD3 activation domain was linked in frame directly to the transmembrane domain. In some embodiments, two CAR chains were encoded in the same bicistronic expression cassette, separated by 2A ribosomal skip element, thus enabling co-expression of the two CAR chains in each T cell transduced with the lentiviral construct encoding the bicistronic CAR. CAR constructs sequences were cloned into a third generation lentiviral plasmid backbone under the control of the human EF-1α promoter (Lentigen Technology Inc., Gaithersburg, Md.). Lentiviral vector (LV) containing supernatants were generated by transient transfection of HEK 293T cells and vector pelleted by centrifugation of lentiviral vector-containing supernatants, and stored at −80° C. 
     (c) Primary T Cell Purification and Transduction 
     Human primary T cells from healthy volunteers were purified from whole blood or buffy coats (purchased from commercial provider with donor&#39;s written consent) using immunomagnetic bead selection of CD4 +  and CD8 +  cells according to manufacturer&#39;s protocol (Miltenyi Biotec, Bergisch Gladbach, Germany). T cells were cultivated in TexMACS medium supplemented with 200 IU/ml IL-2 at a density of 0.3 to 2×10 6  cells/ml, activated with CD3/CD28 MACS® GMP T Cell TransAct reagent (Miltenyi Biotec) and transduced on day 2 with lentiviral vectors encoding CAR constructs in the presence of 10 ug/ml protamine sulfate (Sigma-Aldrich, St. Louis, Mo.) overnight, and media exchanged on day 3. Cultures were propagated in TexMACS medium supplemented with 200 IU/ml IL-2 until harvest on day 8-13. 
     (d) Immune Effector Assays (CTL and Cytokine) 
     To determine cell-mediated cytotoxicity (CTL assay), 5,000 target cells stably transduced with firefly luciferase were combined with CAR T cells at various effector to target ratios and incubated overnight. SteadyGlo reagent (Promega, Madison Wis.) was added to each well and the resulting luminescence quantified as counts per second (sample CPS). Target only wells (max CPS) and target only wells plus 1% Tween-20 (min CPS) were used to determine assay range. Percent specific lysis was calculated as: (1-(sample CPS-min CPS)/(max CPS-min CPS)). Supernatants from co-cultures at E:T ratio of 10:1 were removed and analyzed by ELISA (eBioscience, San Diego, Calif.) for IFNγ, TNFα and IL-2 concentration. 
     (e) Flow Cytometric Analysis 
     For cell staining, half a million CAR T transduced cells were harvested from culture, washed two times in cold AutoMACS buffer supplemented with 0.5% bovine serum albumin (Miltenyi Biotec), and CAR surface expression detected by staining with CD22-His peptide followed by anti-His secondary detection reagent, simultaneously with CD19 Fc peptide followed by anti-Fc conjugate (the secondary detection reagents were purchased form Jackson ImmunoResearch, West Grove, Pa.). Anti-CD4 antibody conjugated to VioBlue fluorophore (Miltenyi Biotec) was used where indicated, as per vendors&#39; protocol. Non-transduced cells were used as negative controls. Dead cells in all studies were excluded by 7AAD staining (BD Biosciences, San Jose, Calif.). Cells were washed twice and resuspended in 200 ul Staining Buffer before quantitative analysis by flow cytometry. Flow cytometric analysis was performed on a MACSQuant® 10 Analyzer (Miltenyi Biotec), and data plots were generated using FlowJo software (Ashland, Oreg.). 
     Results 
     Dual-targeting CAR constructs comprised of different co-stimulatory domains were designed. CAR constructs are listed in Table 1. Schematic representation of CAR design configurations is provided in  FIGS. 6A-6D . In some embodiments, the tandem CAR antigen-binding domain, comprised of anti-CD22 ScFv and anti-CD19 scFv sequences, were linked in tandem, in the following order: anti-CD22 scFv-anti CD19-scFv-hinge-transmembrane domain-endodomain ( FIGS. 6A and 6B ). The targeting tandem domain configuration was based on CAR 22-19 (LTG2681) in all cases. Anti-CD 22-19 CAR construct LTG2737 contained the CAR sequence identical to the Anti-CD 22-19 CAR construct LTG2681, but without use of the Woodchuck Hepatitis Virus (WHP) Posttranscriptional Regulatory Element (WPRE) during its construction. 
     Several CAR T constructs were generated by linking the CAR antigen-binding domain in frame to CD8a hinge and transmembrane domains (constructs LTG2737, D0135, D0136, D0137, D0145, D0146, D0147, D0148, and D0149). In other constructs a transmembrane domain sequence matching the co-stimulatory domain was utilized: CD28 for D139, D140, OX40 for D0137, D0147, D0148. The transmembrane domain was linked in frame to a co-stimulatory domain derived from 4-1BB (LTG2737), CD28 (D0135, D0139, D0140), ICOS (D136, D146, D148, D149), OX40 (D0137, D0145, D0147, D0148) or CD27 (D0138, D0149). All CAR molecules contained the CD3 zeta signaling domain (CD247, aa 52-163, Ref sequence ID: NP_000725.1). In one embodiment, the endodomain of the CAR was comprised of two co-stimulatory domains, CD28 and 4-1BB, connected in tandem (D0140,  FIG. 6B ). In some embodiments, two distinct CAR molecules were co-expressed in the same T cell using a 2A ribosomal skip element for bicistronic expression (D146, D147, D148, D149,  FIG. 6C, 6D ). In this configuration, each CAR chain contained only one scFv, targeting either the CD19 or CD22 antigen, and both chains were co-expressed in each transduced T cell via transduction with a single lentiviral vector encoding the bicistronic sequence. In some embodiments, on at least one of the CAR chains, no co-stimulatory domain was used, so that the CD3 activation domain was linked in frame directly to the transmembrane domain of one of the CAR chains expressed concurrently in the same cell (D0146, D0147,  FIG. 6C ). CAR constructs sequences were cloned into a third generation lentiviral plasmid backbone under the control of the human EF-1α promoter (Lentigen Technology Inc., Gaithersburg, Md.).

     The surface expression of anti-CD22-19 CAR incorporating various co-stimulatory domains, is shown in  FIG. 7 . The expression level for each ScFv-containing CAR was determined by flow cytometric analysis of LV-transduced T cells from healthy donors using simultaneous staining for the two scFv CAR targeting domains i) CD22-his, followed anti-his-PE; ii) CD19 Fc recombinant protein, followed by anti Fc-A647. All anti-CD22-19 CAR were highly expressed in human primary T cells as compared to non-transduced T cell controls. CAR expression levels ranged from 71%-90% ( FIG. 7 ). 
     As shown in  FIGS. 9A-9D , high cytolytic activity of the anti-CD22-19 CAR was demonstrated: Human primary T cells were transduced with LV encoding CAR constructs LTG2737, D0135, D0136, D0137, D0138, D0139, D0140, D0145, D0146), then incubated for 18 hours with the Raji, 293T, 293TCD19 or 293TCD22 cell lines, stably transduced with firefly luciferase, for luminescence based in vitro killing assays. Effector to target (ET) ratios of 2.5:1, 5:1 or 10:1 were used, as noted in the legend to the right of each plot. Raji cells express CD19 and CD22 on their surface, while the negative controls, 293T do not. The 293TCD19 and 293TCD22 target lines were generated to stably express either the CD19 or CD22 target antigen, respectively, and were used to evaluate the capability of the dual-targeting CAR constructs with different co-stimulatory domains to accomplish target lysis when triggered by each single target antigen, CD19 or CD22, independently of the other antigen. 
     Raji cells were lysed effectively by all dual targeting CARs, but not by the untransduced T cells, UTD, a negative control ( FIG. 9A ). By comparison, all dual-targeting CAR constructs lysed the single-antigens lines 293TCD19 and 293TCD22, demonstrating the capability of these CAR constructs to trigger their anti-tumor lytic function when activated either by CD19 antigen alone, or by CD22 antigen alone ( FIGS. 9B and 9D , respectively). By contrast, none of the dual-targeting anti-CD22-19 CAR lysed the antigen-negative cell line 293T ( FIG. 9C ). Therefore, all anti-CD22-19 CAR were functional in tumor lines co-expressing the CD19 and CD22 antigens, and also in 293TCD19 and 293T CD22 lines expressing either CD19 or CD22 single antigen, and had no spontaneous killing activity against CD19-CD22-cell line 293T, underscoring the target specificity of these constructs. 
     The capacity of anti-CD22-19 CAR with various co-stimulatory domains for cytokine secretion was then evaluated ( FIG. 8 ). The CD19+CD22+ Raji tumor cells were co-incubated with the tandem anti-CD22-19 CAR T cells expressing constructs LTG2737, D0135, D0136, D0137, D0138, D0139, D0140, D0145, D0146, or negative control untransduced T cells (UTD) at effector to target ratio of 10:1 overnight, and culture supernatants were analyzed by ELISA for IFN gamma, TNF alpha, and IL-2 ( FIG. 8 ). All dual-targeting CARs strongly induced IL-2 and TNFα in response to tumor cells, whereas the negative control (untransduced, UTD) yielded no appreciable cytokine induction ( FIG. 8 ). Notably, the elaborated levels of IFN gamma, were strongly induced in all CAR 22-19, but were especially high for CAR constructs D0146, D0139, D0136, indicating that the strength of cytokine response of the anti-CD22-19 CAR may be modulated by the composition of co-stimulatory domains utilized in CAR design. Overall, the induced secretion profiles of IFN gamma, TNF alpha, and IL-2 demonstrated the high potency of all CAR 22-19 constructs. Importantly, anti-CD22-19 CAR produced little to no cytokine secretion in the absence of tumor cells (CAR T alone group), which further confirms CAR specificity, and indicates a lack of tonic signaling by the tandem anti-CD22-19 CAR with various co-stimulatory domains.
