     BACKGROUND 
     While adoptive cell therapies show efficacy in cancer treatment, the effectiveness of these therapies can be further improved through genetic engineering of T cells for better expansion and persistence. T cells require functionally non-overlapping co-stimulatory signals from CD28 family and tumor necrosis factor receptor (TNFR) family along with antigen triggered TCR signaling to promote full-fledged activation and persistent proliferation. In developing gene-engineered T cell therapeutics, there is a need to introduce chimeric T cell co-stimulatory molecules that can be locally activated upon T cell engaging with pathological antigens to potently augment T cell activation for increased therapeutic efficacy. Currently, the second generation of chimeric co-stimulatory molecules incorporating one co-stimulatory signaling domain from proteins of either CD28 family or TNFR family has been widely adopted in CAR T cell therapy. Chimeric antigen receptors (CARs) integrating one co-stimulatory signaling domain augment T cell function through both activating and co-stimulatory signals, thus resulting in enhanced anti-tumor potency and T cell persistence. Given that the capacity for T cell to expand depends on the structural design, the current second generation co-stimulatory proteins may not be optimal for induction of a durable tumor remissions. Thus, there is a desired effort to develop third-generation chimeric molecules combining two co-stimulatory signaling domains from CD28 family and TNFR family members to further enhance T cell therapeutic potential, capitalizing on non-overlapping functions of the two families of co-stimulatory molecules. In addition, such third-generation chimeric co-stimulatory molecules can be integrated into TCR T therapy where T cell activation remains suboptimal due to insufficient co-stimulatory signals during activation of exogenously expressed TCRs by antigens. However, existing recombinant DNA strategies often suffer from reduced cell surface expression of the chimeric proteins combining two co-stimulatory signaling domains, preventing realization of the functional potential of the chimeric proteins. The present application addresses such needs. The present application discloses third-generation chimeric T cell co-stimulatory molecules that incorporate two signaling domains from CD28 and TNFR families and express at significantly improved levels than what have been conventionally reported for enhanced T cell functions, and methods of making the co-stimulatory molecules.

     DETAILED DESCRIPTION 
     Provided herein are novel chimeric co-stimulatory intracellular domains. The chimeric co-stimulatory intracellular domains provided herein comprise: (a) a first signaling domain that is based on the intracellular signaling domain of a CD28 family protein; and (b) at least a second signaling domain that comprises a mutant intracellular signaling domain of a TNFR family protein. 
     The CD28 family proteins have a single extracellular immunoglobulin variable-like (IgV) domain followed by a short cytoplasmic tail. Members of the CD28 family proteins include CD28, CD28H, inducible costimulator (ICOS), cytotoxic T lymphocyte-associated antigen 4 (CTLA-4, CD152), program death-1 (PD-1), and B- and T-lymphocyte attenuator (BTLA). CD28, CD28H and ICOS are co-stimulatory proteins that are expressed on T cells that promote activation, high levels of cytokine/chemokine expression, resistance to apoptosis, and proliferation of T cells. 
     The Tumor Necrosis Factor Receptor (TNFR) family proteins includes TNFR1 (tumor necrosis factor receptor 1/TNFRSF1A), TNFR2 (tumor necrosis factor receptor 2/TNFRSF1B), lymphotoxin β receptor/TNFRSF3, OX40/TNFRSF4, CD40/TNFRSF5, Fas/TNFRSF6, decoy receptor 3/TNFRSF6B, CD27/TNFRSF7, CD30/TNFRSF8, 4-1BB/TNFRSF9, DR4 (death receptor 4/TNFRSF10A), DR5 (death receptor 5/TNFRSF10B), decoy receptor 1/TNFRSF10C, decoy receptor 2/TNFRSF10D, RANK (receptor activator of NF-kappa B/TNFRSF11A), OPG (osteoprotegerin/TNFRSF11B), DR3 (death receptor 3/TNFRSF25), TWEAK receptor/TNFRSF12A, TACI/TNFRSF13B, BAFF-R (BAFF receptor/TNFRSF13C), HVEM (herpes virus entry mediator/TNFRSF14), nerve growth factor receptor/TNFRSF16, BCMA (B cell maturation antigen/TNFRSF17, GITR (glucocorticoid-induced TNF receptor/TNFRSF18), TAJ (toxicity and JNK inducer/TNFRSF19), RELT/TNFRSF19L, DR6 (death receptor 6/TNFRSF21), TNFRSF22, TNFRSF23, ectodysplasin A2 isoform receptor/TNFRS27 and ectodysplasin 1-anhidrotic receptor. Interactions between tumor necrosis factor superfamily (TNFSF) ligands and TNF receptor superfamily (TNFRSF) receptors provide the co-stimulatory signals that control the survival, proliferation, differentiation, and effector function of immune cells. Depending upon the specific intracellular signal induced by TNFRSF members, they can be categorized into three groups—death domain (DD)-containing receptors, decoy receptors, and TNF receptor-associated factor (TRAF)-binding receptors. Some TNFRSFs such as TNFR-1, Fas, DR3, DR4, DR5, and DR6, contain their own DDs and/or interact with other cytoplasmic DD-containing adaptor molecules. Some other TNFRSFs, such as TNFR-2, CD27, CD30, CD40, glucocorticoid-induced TNFR family-related gene (GITR), Fn1, lymphotoxin beta-receptor (LTβR), OX40, receptor activator of NF-κB (RANK), and XEDAR, lack a DD and contain motifs with four to six amino acids called TRAF-interacting motifs (TIMs) which recruits TRAF proteins. TRAF proteins are adaptor molecules that activate multiple downstream signaling pathways such as NF-κB, Janus kinase (JNK), ERK, p38MAPK, and PI3K that help in cell survival, proliferation, and cytokine production. In some embodiments, the first signaling domain that is based on the intracellular signaling domain of a CD28 family protein is selected from a CD28 protein, ICOS protein or a combination thereof. In some embodiments, the at least second signaling domain is based on a mutant of the intracellular signaling domain of a TNFR family protein is selected from CD137 (4-1BB) and CD134 (OX-40). 
     Provided herein are novel chimeric co-stimulatory intracellular domains based on the third-generation co-stimulatory domains of the present application. Reduced surface expression is a major hindrance in the development of chimeric co-stimulatory proteins for therapeutic purposes. The present disclosure provides novel chimeric co-stimulatory intracellular domains generated through mutations in the third-generation co-stimulatory domains of the present application that are both highly expressed and highly functional compared to the current second-generation and third-generation chimeric receptors that are effective in inducing costimulation. The chimeric co-stimulatory intracellular domains provided herein comprise: (a) a first signaling domain that is based on the intracellular signaling domain of a CD28 protein, ICOS protein or a combination thereof; and (b) at least a second signaling domain that is a mutant CD137 (4-1BB) intracellular domain or a mutant CD134 (OX-40) intracellular domain. In some embodiments, the mutant CD137 (4-1BB) intracellular domain or the mutant CD134 (OX-40) intracellular domain comprises a deletion, an insertion or a substitution of one or more amino acids in the membrane proximal portion of the CD137 or CD134 intracellular domain. In some embodiments, the one or more amino acids in the membrane proximal portion are ubiquitination sites involved in the ubiquitination and degradation of the CD137 or CD134 protein. In some embodiments, the mutant CD137 (4-1BB) intracellular domain or a mutant CD134 (OX-40) intracellular domain comprises substitution or deletion of one or more lysine residues in the membrane proximal portion of the CD137 or CD134 intracellular domain. In some embodiments, the lysine residues are ubiquitination sites involved in the ubiquitination and degradation of the CD137 or CD134 protein. In some embodiments, the chimeric co-stimulatory intracellular domains provided herein further comprise a third signaling domain. In some embodiments, the third signaling domain can be based on a CD3 signaling domain. 
     In some embodiments, the novel co-stimulatory intracellular domain of the present application can be combined or fused in frame with the extracellular domain of any known co-stimulatory protein, a cell intrinsic immune checkpoint inhibitor, a chimeric antigen receptor, an antibody or a portion thereof, a ligand or a receptor thereof, a cytokine or a receptor thereof, a chemokine or a receptor thereof or a complement receptor, to form a functional recombinant T cell co-stimulatory receptor (RTCR). In some embodiments, the RTCR can be expressed in a cell in combination with another T cell receptor (TCR), chimeric antigen receptor or co-stimulatory protein. A RTCR comprising the novel co-stimulatory intracellular domain disclosed herein, when co-expressed with a TCR in a T cell, significantly increases the cell surface expression of the RTCR, and/or cell proliferation, activation, persistence, cytokine production and/or effector function of the T cell, as compared to a second-generation co-stimulatory receptor. 
     A highly efficacious adoptive cell therapeutic targeting a shared and safe tumor associated antigen and comprising a cell-intrinsic inhibitor of T cell exhaustion able to withstand the suppressive tumor microenvironment is described in the present application. An exemplary chimeric molecule expressing the extracellular domain of PD-1 and a functionally optimized chimeric intracellular co-stimulatory domain are disclosed herein. Modified T cells expressing the chimeric molecule of the present disclosure are generated to show the efficacy of the chimeric molecule in enhancing T cell stimulation, activation and proliferation. Both molecules are expressed on the same T cell, creating a TCR-T product that responds robustly to tumor cells expressing both the cognate MHC/peptide complex and high levels of PD-L1//PD-L2. 
     For exemplification, a cell-intrinsic inhibitor of T cell exhaustion is developed by co-expression of third generation chimeric PD-1 receptors combined with T cell receptors targeting tumor associated or specific antigens to enhance the efficacy of T cell mediated killing of tumor cells. The 3 rd  generation chimeric receptors disclosed herein can be used in combination with any endogenous or modified T cell receptors as well as with chimeric artificial receptors (CARs). The results herein show that the 3 rd -generation co-stimulatory molecules disclosed herein produces T cells with high physiological avidity and persistent proliferative potential, while negating negative signaling by PD-1, delivering instead co-stimulatory signals in a PD-L1 rich environment. The novel co-stimulatory molecule can be co-expressed with a tumor associated antigen (TAA) specific TCR and used to target PD-L1/PD-L2 and the TAA expressing tumors. This demonstrates that the synergistic effect between the TCR activation and co-stimulatory molecule significantly increases the therapeutic window and generate a potentially more effective candidate for clinical investigation. In the disclosure described below, the design of the third-generation chimeric proteins is systematically optimized, to further validate in vitro the improved anti-cancer effectiveness, and to investigate the in vivo anti-tumor efficacy. Co-stimulatory molecules incorporating the extracellular domains of PD-1 with the intracellular domains of CD28, ICOS, CD134, and CD137 alone and in various combinations are generated. These sequences are optimized for surface expression and functionality by incorporating key mutations/deletions within the signaling domain of the chimeric receptors, focusing on the junction between CD28 and TNF-receptor family signaling domains. The functionality of these receptors is tested based on surface expression, in-vitro signaling, in-vitro T cell conjugation, cytokine production, proliferation, and cytotoxicity using a combination of soluble and plate-bound antibody stimulations and K562 target cells expressing PD-L1 or A375 tumor cells. 
     The disclosure herein provides an approach in which the TCR-T product co-expresses a chimeric co-stimulatory molecule alongside a recombinant TAA-specific TCR or an endogenous TCR. This approach allows for the targeting of the tumor associated antigen with simultaneous antagonization of checkpoint inhibition and delivery of co-stimulatory signals to the transfused T cell product. This approach not only results in a much-improved product, but also help to develop a universal function-boosting platform for additional TCR-T products. 
     The key technical challenge hindering the clinical adoption of 3 rd -generation CARs combining the two domains has been the abnormally low expression of chimeric proteins at the cell surface and associated diminished functionality (Zhao, 2015, Guedan, 2018). This has held true in co-stimulatory molecules where the combination of the CD28 and CD137 signaling domains resulted in a poorly expressed and non-functional receptor (Ankri, 2013). Disclosed herein is a switch receptor/co-stimulatory molecule based on the ICOS/CD137 signaling domain and optimized for surface expression that is a significant improvement over past trials using the CD28 signaling domain alone, mediating both increased effector function and persistence of adoptively transferred cells. Results described herein show that the 3 rd -generation co-stimulatory molecule disclosed herein produces T cells with high physiological avidity and persistent proliferation potential, while negating negative signaling by PD-1, delivering instead a co-stimulatory signal in a PD-L1 rich environment. The novel switch receptor/co-stimulatory molecule disclosed herein can be co-expressed with an endogenous TCR or a TAA specific TCR and used to target PD-L1/PD-L2 expressing tumors. This demonstrates that the synergistic effect between the TCR activation and co-stimulatory molecule significantly increases the therapeutic window for a potentially more effective candidate for clinical investigation. 
     Tumor associated antigens and tumor specific antigens allow for the immunological targeting of the tumor with relatively minimal risk of off-tumor, on-target side effects. Tumor cells can upregulate these antigens which can then be targeted by the human immune response or ACT. The disclosure herein combines a co-stimulatory molecule based on 3 rd -generation CARs that exhibits superior functionality to CD28-based receptors with a new affinity enhanced TCR targeting TAAs to generate a TCR-T product that resists the suppressive function of the TME.

     In some embodiments, the chimeric intracellular domain further comprises a third signal transduction domain. In some embodiments, the third signal transduction domain is derived from any one of a CD3 signaling domain, a CD2 signaling domain, or an interleukin 2 receptor binding (IL-2RB) protein signaling domain. In some embodiments, the CD3 signaling domain is derived form a CD3ζ or a CD3ε domain or a combination thereof. 
     In some embodiments, the chimeric intracellular domain further comprises a third signal transduction domain derived from a CD3ζ protein. In some embodiments, the third signal transduction domain of the chimeric intracellular domain is a CD3ζ protein of amino acid sequence according to SEQ ID NO: 18. In some embodiments, the third signal transduction domain of the chimeric intracellular domain is a CD3ζ comprising an amino acid sequence having at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97% or 99% identity to according to SEQ ID NOs: 18.

     The compositions comprising the cells or modified T cells of the disclosure, and the plurality of modified T cells produced by the methods of the disclosure, intended for administration to a subject may be required to meet one or more “release criteria” that indicate that the composition is safe and efficacious for formulation as a pharmaceutical product and/or administration to a subject. Release criteria may include a requirement that a composition of the disclosure (e.g., a cell or modified T cell of the disclosure) comprises a particular percentage of cells or modified T cells expressing the RTCR of the disclosure on their cell surface. The expansion process should be continued until a specific criterion has been met (e.g., achieving a certain total number of cells or modified T cells of the disclosure or a certain percentage of total number of cells or modified T cells expressing the RTCR of the disclosure). 
     Certain criterion signal a point at which the expansion process should end. For example, cells should be formulated, reactivated, or cryopreserved once they reach a cell size of 300fL (otherwise, cells reaching a size above this threshold may start to die). Cryopreservation immediately once a population of cells reaches an average cell size of less than 300 fL may yield better cell recovery upon thawing and culture because the cells haven&#39;t yet reached a fully quiescent state prior to cryopreservation (a fully quiescent size is approximately 180 fL). Prior to expansion, T cells of the disclosure may have a cell size of about 180 fL, but may more than quadruple their cell size to approximately 900 fL at 3 days post-expansion. Over the next 6-12 days, the population of T cells will slowly decrease cell size to full quiescence at 180 fL. 
     A process for preparing a cell population for formulation may include, but is not limited to the steps of, concentrating the cells of the cell population, washing the cells, and/or further selection of the cells via drug resistance or magnetic bead sorting against a particular surface-expressed marker. A process for preparing a cell population for formulation may further include a sorting step to ensure the safety and purity of the final product. For example, if a tumor cell from a patient has been used to stimulate a modified T cell of the disclosure or that have been modified in order to stimulate a modified T cell of the disclosure that is being prepared for formulation, it is critical that no tumor cells from the patient are included in the final product. 
     In some embodiments, the cell disclosed herein, or the modified T cell disclosed herein, expresses on the cell surface the RTCR comprising a mutant CD137 or a mutant CD134 intracellular signaling domain disclosed herein, at a level that is at least about 2×, 3×, 4×, 5×, 6×, 7×, 8×, 9×, 10× or 20×, more as compared to the level of expression of a co-stimulatory molecule comprising a wild type CD137 or a wild type CD134 intracellular domain, respectively.

     Lentiviral Production and Preparation of Retronectin Plates 
     VSV pseudotyped lentivirus was produced in 6 well plates. In brief, 293FT were seeded the night before or the day of at 0.9×10 6  or 1.4×10 6  cells/well, respectively. Once the cells had adhered and reached at least 80% confluency a mix of lentiviral plasmid, packaging vector (psPAX2) and VSV-G envelope expressing plasmid (PMD2.G) were transfected using lipofectamine 3000 (Invitrogen), according to the manufacturer&#39;s protocol. After 18 hrs, the media was replaced with 3mLs of fresh DMEM. Viral supernatants were harvested 48 hrs following changing the media and spun down at 1500RPM to remove 293FT cell/debris. Retronectin was coated on 24 well non-tissue culture treated plates at 20 m/well in PBS−/− for 2 hrs at 37° C. or overnight at 4° C. Retronectin was removed and washed once with PBS prior to addition of lentiviral SN (2mLs). The plate was then spun at 1500 G for 90 minutes at 32° C. to concentrate viral particles onto the retronectin. Lentiviral SN was removed immediately prior to transduction of primary T cells or tumor cells. Alternatively, T cells were transduced with polybrene at 8 ug/mL with a spinfection of 800 G for 2 hrs at 32° C. 
     T Cell Culture, Transduction, and Isolation 
     Human PBMCs were activated in T cell growth media with CD3/28 microbeads (Invitrogen) in complete RPMI (100 ul beads/50×10 6  PBMCs). 48 hrs after activation, activated PBMCs were transferred to Lentiviral-coated Retronectin plates for 48 hrs before being transferred to 6 well plates containing fresh T cell growth media. After an additional 24 hrs in culture cell transduction was determined by flow cytometry and transduced cells were enriched based on huEGFRt expression. To isolate cells based on EGFR expression, T cells cultures were collected and activation beads removed. Cells were then stained in 1:100 anti-EGFR-APC antibody in MACS buffer at 4° C. for 30 minutes. Cells were then washed and incubated with anti-APC microbeads (Miltenyi) for 15-30 minutes at 4° C. Unbound microbeads were then removed by centrifugation and huEGFRt cells were isolated by positive selection on mini-macs columns. Cells were eluted from the mini-MACS columns and put back into culture in T cell growth media and used within 2 weeks for experiments. To create stable cell lines, cells were collected and transduced as with primary T cells. EGFR selection was performed twice, two weeks apart. 
     T Cell Stimulation 
     In the case where T cells were stimulated with plate bound antibodies, maxisorp Flat-bottom plates (Invitrogen) were coated with the indicated amount of anti-human CD3 antibody (HIT3a-Biolegend) in PBS−/− for 2 hrs at 37° C. Plates were washed twice in basal RPMI before use. For K562 stimulation K562 cells were collected and resuspended in Cytokine media and aliquoted to U-bottom plates. Similarly, A375 cells were plated 1 day prior to the addition of T cells in DMEM in 96 well flat-bottom plates. The media was exchanged prior to the addition of cognate T cells. Following EGFR+ selection, T cells were collected, counted, and resuspended at the appropriate concentration in Cytokine media and distributed to antibody or APC-bearing wells. For K562 experiments anti-CD3 (HIT3a/Biolegend) was added at the indicated dose following 1-2 hrs of K562/T cell interaction at 37° C. In the case where T cell proliferation was to be tracked, T cells were labelled with Violet Tracking Dye (CTV) according to Biolegend&#39;s protocol prior to the addition to stimulatory plates. Supernatant was collected at 18-36 hr post stimulation to assess cytokine secretion and proliferation/T cell killing was assessed following 96 hrs of stimulation. 
     Cytokine Multiplex Assay 
     Following collection of T cell supernatants cytokines were measured with the Legendplex Multi-Analyte Flow Assay Kit foe human Th or Th1 cytokines (Biolegend). Manufactures protocol was followed with the following exceptions: 75 uL T cell SN was used to measure cytokines and 2 uL of each reagent was used/well. Secreted cytokines were measured by flow cytometry and the values were normalized to the maximal response of the control group in order to combine and analyze multiple experiments and normalize for variability between experiments and donors. 
     Conjugation Assays 
     To assess conjugation of T cells to target cells, T cells were labelled with CFSE (Biolegend) and K562_HLA-A2 or K562_HLA-A2_PD-L1 cells were labelled with CTV according to manufacturer&#39;s protocols. T cells and APCs were mixed in a 1:2 ratio and briefly centrifuged in a 1.5 mL eppendorf tube to encourage conjugation. Cell pellets were incubated at 37° C. for 30 minutes and then cell pellets were gently resuspended by repeat pipetting (20×) with a p200 and a cut-off pipette tip and assessed immediately by flow cytometry. 
     Flow Cytometry 
     Cells were collected and washed in MACS Buffer (PBS−/−, 1% FBS, 1 mM EDTA) before being stained in MACS buffer containing relevant antibodies. Anti-EGFR-APC, anti-mouse TCRbeta-FITC, anti-human PD1-PE, anti-CD3 APC-Cy7, anti-CD8 PE-Cy7 were all purchased from biolegend. Following addition of antibodies, cells were stained for 30-60 minutes at 4° C. For the detection of CD-19 CAR expression cells were incubated with CD-19Fc recombinant protein in MACS buffer at 1 μg/mL for 30 minutes at RT. Cells were then washed and incubated with anti-human FC antibody at 1:100 dilution. Cells were then washed 3× in MACS buffer and analyzed on an Acea NovoCyte flow cytometer. Cells were collected at constant volume, allowing for accurate cell counts to be obtained. 
     Example 1: Design of Co-Stimulatory Molecules Comprising Chimeric Intracellular Signaling Domains 
     The disclosure herein provides the design of the co-stimulatory molecules comprising intracellular signaling domains comprising or derived from CD137/4-1BB or CD134/OX-40 receptors as depicted in  FIG. 1 . Examination of the sequence of the CD137 family of cytoplasmic tails ( FIG. 1 ) showed a common membrane-proximal polybasic domain as well as several lysine residues that could serve as ubiquitination sites, as well as the TRAF binding domain that serves to activate the NF-κB signaling pathway following receptor ligation. Without being bound by the theories, the conserved lysine residues may function as ubiquitination sites that could control the ubiquitination and degradation CD134/CD137 and that the disrupted location of the CD137 or CD134 cytoplasmic tail in the potential CD28/ICOS-CD137 CAR or CD28/ICOS-CD134 CAR receptors, respectively, could be affecting the localization or half-life of the resulting molecule, through either the poly-basic domain or the conserved lysine residues. New fusion domains of ICOS/CD28 intracellular domain and the cytoplasmic domains of CD137 or OX-40 lacking the polybasic sequence and the conserved lysine residues, as well as their wild-type (WT) counterparts were generated ( FIGS. 2A and 2B ). A portion of the cytoplasmic domain of CD28 responsible for the binding of Lck and Vav3 to possible enhance stimulation was also included. The extracellular domain of PD-1 was used, creating either dominant-negative (DN) version by omitting the intracellular tail or an inhibitory-switch receptor that would change a negative regulatory signal into a positive one, thus providing a cell-intrinsic PD-1 blockade. The cytoplasmic tail, i.e., intracellular co-stimulatory domain, described herein can be expanded through the use of cytoplasmic tails of other signaling proteins of interest to create new CAR receptors or different inhibitory-switch receptors, or express other immune-modulatory extracellular domains, as detailed in  FIG. 3 . 
     Example 2: Generation and Testing of the In-Vitro Functionality of Checkpoint Co-Stimulatory Molecules 
     The disclosure herein provides the design of the co-stimulatory molecules and validation of their effect on function of a high affinity TCR. The co-stimulatory molecules described herein were designed as depicted in  FIGS. 2A and 2B . In all recombinant receptors, the PD1 signal peptide (SP) was exchanged for the signal peptide from HLA-A2, which increases the surface expression of the receptor. As controls, the PD1-WT and a truncated PD-1 lacking the ITIM-containing intracellular tail (TLs) were included. Two second-generation receptors, containing the transmembrane and intracellular domains of CD28 or ICOS were included as 2 nd -generation control receptors. Additionally, fifteen 3 rd -generation receptors containing the transmembrane and intracellular domains derived from ICOS and/or CD28 linked to an intracellular signaling domain of a TNF-Receptor super family member were generated. The first contained the intracellular domain of wild type CD137/4-1BB (HLA A2-SP_PD1_ICOS_BB: SEQ ID NO: 26), while the second and third contained either the CD137/4-1BB domain or the CD134/OX-40 intracellular domain with key mutations incorporated to increase surface expression (HLA A2-SP_PD1_ICOS_BBt: SEQ ID NO: 27 and HLA A2-SP_PD1_ICOS_OX40t: SEQ ID NO: 28, respectively). Further 3 rd  generation receptors described herein contain a chimeric intracellular domain comprising a portion of CD28 intracellular domain inserted within an ICOS intracellular domain that is further linked to either the mutated CD137 (ICOS4BBt) or mutated CD134/OX40 (ICOS-OX40t) domains (HLA A2-SP_PD1_ICOS(28) BBt: SEQ ID NO: 29 and HLA A2-SP_PD1_ICOS(28)_OX40t: SEQ ID NO: 30). Two more 3 rd  generation receptors were created as described herein containing a CD28 intracellular domain linked to either mutated CD137 (28_BBt) or mutated CD134/OX40 (28_OX40t) domains (HLA A2-SP_PD1_28_BBt: SEQ ID NO: 131 and HLA A2-SP_PD_28_OX40t: SEQ ID NO: 132) ( FIG. 2A ). These vectors were cloned into a lentiviral vector and fused by a self-cleaving peptide to a truncated huEGFR receptor (huEGFRt) for tracking transduced cells and magnetic selection. When these receptors were expressed by lentiviral transduction into primary T cells, each receptor expresses significantly over endogenous PD-1 levels ( FIG. 4A ). While the 2 nd  generation co-stimulatory molecules were well expressed, the inclusion of the CD137 (4-1BB) intracellular domain resulted in a considerable decrease in surface expression of the recombinant receptor. The disclosure herein shows that inclusion of the mutated intracellular domains, which maintain the TRAF-binding domains, rescues the surface expression of these optimized 3 rd  generation receptors. The surface expression of huEGFRt and co-stimulatory molecules demonstrates the increased expression of the truncated CD137 (4-1BB) design (ICOS_BBt) compared to the non-truncated version (ICOS_BBwt). Similar mutations in the cytoplasmic domain of CD134 (OX-40) also resulted in high surface expression of the co-stimulatory molecules ( FIG. 4B ). 
     Following transduction, T cells were isolated based on the expression of huEGFRt, to &gt;90% purity, and used in restimulation experiments. The results disclosed herein demonstrate that, in-vitro, engagement of co-stimulatory molecule enhanced T cell cytokine production and proliferation, especially at lower doses of anti-CD3 antibody ( FIGS. 5A-5D ). To make a more physiological system, either HLA-A2 alone or HLA-A2 alongside PD-L1 were overexpressed on K562 cells and incubated with the co-stimulatory receptor-transduced T cells and the indicated dose of anti-CD3. Incubation with K562: PD-L1 cells reduced the amount of secreted cytokine, especially with T cells overexpressing PD1_WT ( FIG. 6A ). While expression of either PD1_TLs or PD1_ICOS_BBwt did little to affect the secretion of IL-2, TNF, or IFNγ, the expression of PD1_28 or PD1_ICOS increased effector cytokine secretion 3-4 fold over GFP control in the presence of PD-L1 expressing K562 cells. Notably, both PD1_ICOS_BBt and PD1_ICOS_OX40t co-stimulatory molecules further improved on this effect, increasing effector cytokine secretion 2 to 3-fold over PD1_ICOS expressing cells in the presence of PD-L1 ( FIG. 6C ). The expression of PD1_28, PD1_28_BBt and PD1_28_OX40t resulted in comparable effector cytokine secretion ( FIG. 6B ). None of the constructs were constitutively active and had minimal effect on cytokine secretion in the absence of PD-L1 or anti-CD3, indicating the necessity of both PD-1 and antigen to initiate a T cell response. Fitting with the cytokine data, T cells expressing a) PD1_28, PD1_28_BBt and PD1_28_OX40t ( FIG. 7A , lower panels, and  FIG. 7C ), and b) PD1_ICOS_BBt and PD1_ICOS_OX40t ( FIG. 7B , lower panels, and  FIG. 7C ), proliferated best in response to K562 cells expressing PD-L1 and were best able to kill PD-L1 expressing K562 cells ( FIGS. 7A-7B , upper panels). Fitting with the cytokine data, T cells expressing PD1_ICOS_BBt and PD1_ICOS_OX40t proliferated best in response to K562 cells expressing PD-L1 and were best able to kill PD-L1 expressing K562 cells ( FIG. 7C-7E ). Again, this response required both anti-CD3 and PD-L1 expression. The co-stimulatory molecules demonstrated co-stimulatory ability as their expression increased T cell proliferation when cells were stimulated on 96-well plates coated with anti-CD3 and anti-PD1 ( FIG. 8 ). 
     The effect of the receptors with mutation of the polybasic and lysine residues is less than the PD1_ICOS_BBt co-stimulatory molecule, in terms of both surface expression of the co-stimulatory molecule ( FIGS. 9A-9B ), effector cytokine production in response to stimulation with anti-CD3 antibody ( FIG. 9C ), and T cell proliferation in response to stimulation with target cells expressing PD-L1 ( FIG. 9D ). The PD1_ICOS_OX40t receptor (with truncated OX40 intracellular domain) had an effect comparable to that of the wild type PD1_ICOS_OX40wt receptor (comprising wild type OX40 intracellular domain), in terms of both surface expression of the co-stimulatory molecule ( FIGS. 10A-10B ), effector cytokine production in response to stimulation with anti-CD3 antibody ( FIG. 10C ), and T cell proliferation in response to stimulation with target cells expressing PD-L1 ( FIG. 10D ). 
     Further, the ICOS-based co-stimulatory molecules encouraged T cell: PD-L1 expressing (PD-L1+) target cell interaction in a flow-based conjugation assay, suggesting that these receptors encourage prolonged T cell—APC interactions while scanning for cognate antigen, a useful property when scanning for low-abundance antigen in the TME ( FIGS. 11A-11B ). 
     The disclosure herein shows that the co-stimulatory molecules based on the modified 3 rd -generation intracellular signaling domain disclosed herein are superior to currently existing PD1_28 co-stimulatory molecules in enhancing T cell effector function when responding to a PD-L1+ target cell. This includes increased T cell proliferation, cytokine secretion, and target cell killing. The 3 rd -generation intracellular signaling domain disclosed herein can be successfully combined with TCR-T therapy targeting TAAs. 
     Example 3: In-Vitro Preclinical Studies 
     Described herein are T cells expressing specific HLA-A2/NY-ESO specific TCRs and co-stimulatory molecules comprising ICOS and mutated CD137 signaling domains, that increase expression of the co-stimulatory molecule on T cell surface ( FIG. 12A ), effector cytokine production ( FIG. 12B ), and killing of target cells expressing NY-ESO ( FIG. 12C ), as compared to T cells expressing the specific HLA-A2/NY-ESO specific TCRs alone. 
     Described herein are CD-19 CAR constructs comprising the modified 3 rd -generation intracellular signaling domains disclosed herein. The CD-19 (FMC63scFV) CARs with 3 rd -generation intracellular signaling constructs described herein include constructs comprising the intracellular chimeric domains: CD28-CD137-CD3ζ (28_BBwt_z), CD28-CD137mutant-CD3ζ (28_BBt_z), CD28-CD134mutant-CD3ζ (28_OX40t_Z), ICOS-CD137-CD3ζ (ICOS_BB_z), ICOS-CD137mutant-CD3ζ (ICOS_BBt_z), and ICOS-CD134mutant-CD3ζ (ICOS_OX40t_z). Also, provided are CD-19 CARs with a 3 rd -generation intracellular signaling construct with a portion of CD28 inserted within the ICOS domain: ICOS(28)-CD137-CD3ζ (ICOS(28)_BBwt_z), ICOS(28)-CD137mutant-CD3ζ (ICOS(28)_BBt_z), and ICOS(28)-CD134mutant-CD3ζ(ICOS(28)_OX40t_z). Second-generation constructs comprising CD137-CD3ζ (BBwt_z), CD28-CD3ζ (28_z) and ICOS-CD3ζ (ICOS_z) are used as controls. Similar to the study described herein using the PD-1 3 rd -generation intracellular signaling constructs, the CD19 CAR constructs with the CD137 and CD134 mutants domains showed higher expression as compared to the corresponding constructs with wild type CD137 and CD134 domains (28_BBwt_z and ICOS_BBwt_z, respectively) ( FIGS. 13A-13B ). In-Vitro studies described herein show increased killing of CD19 expressing cells (CD19+) ( FIGS. 14A-14B  and  FIGS. 15C-15D ), increased effector cytokine production ( FIG. 14C , right panels) and increased T cell proliferation and persistence ( FIGS. 15A-15B and 15E ), by primary T cells transduced with the 3 rd  generation CD28 based and ICOS based CD19 CARs. 
     The disclosure also shows that expression of CD28 based receptors comprising a mutated CD134/CD137 signaling domains and ICOS based receptors comprising a mutated CD134/CD137 signaling domains, increased binding of BCMA specific T cells (BCMA CAR T cells) to the target antigen (BCMA-Fc) ( FIGS. 16A-16B ). Also, the disclosure shows that expression of the CD28 based receptors comprising a mutated CD134/CD137 signaling domains and ICOS based receptors comprising a mutated CD134/CD137 signaling domains, increased proliferation and effector cytokine production ( FIGS. 16C and 16E ), and target cell killing ( FIG. 16D ) by the BCMA specific T cells in response to myeloma cell line expressing BCMA.
