Title: Major histocompatibility complex-based chimeric receptors and uses thereof for treating autoimmune diseases

Description:
RELATED APPLICATION 
     This application claims the benefit of the filing date of U.S. Provisional Application Ser. No. 62/584,449, filed on Nov. 10, 2017. The entire contents of this referenced application are incorporated by reference herein. 
    
    
     BACKGROUND OF THE INVENTION 
     Autoimmune diseases are characterized by abnormal immune responses against self-antigens, leading to damage or disruption of tissues. Multiple sclerosis (MS) is a central nervous system autoimmune disease, in which activated autoreactive T cells invade the blood brain barrier, initiating an inflammatory response that leads to myelin destruction and axonal loss. Although the etiology of MS, the mechanisms associated with its onset and progression, and determination of its outcome remains unelucidated, all available evidence suggests that therapies specifically targeting the pathologic immune cells responsible for MS would have improved therapeutic outcomes over available therapies. Reinhard et al.,  Proceedings of the National Academy of Sciences,  101(suppl 2):14599-14606; 2004. This strategy could be extended to other immune disorders with similar mechanisms, including rheumatoid arthritis. Carol et al.,  Nature Reviews Immunology,  2(2):85-95, 2002. 
     The major histocompatibility complex (WIC), known as human leukocytes (HLA) in humans, is a set of cell surface proteins essential for the immune system to recognize foreign agents. MHC complexes bind to antigens derived from pathogens and display such to T cells, which are then activated, leading to elimination of cells displaying foreign antigens. MHC complexes may also display intact, and in some cases misfolded, host-derived proteins to B cells thereby inducing the autoantibody responses characteristic of autoimmune disorders. Jiang et al.,  International immunology,  25(4):235-246 (2013), and Busch et al.,  The EMBO journal,  15(2):418, (1996). 
     SUMMARY OF THE INVENTION 
     In aspect, the disclosure features a major histocompatibility complex (MHC)-based chimeric receptor (CAR), comprising: (i) an extracellular domain of a MHC molecule conjugated to an antigenic peptide from an antigen involved in an autoimmune disease; and (ii) a cytoplasmic signaling domain, at least one co-stimulatory domain, or a combination thereof. The MHC-based CAR may further comprises a hinge domain located between (i) and (ii). The antigenic peptide is dependent on the autoimmune disorder and may be from myelin basic protein (MBP), proteolipid protein (PLP), insulin, glutamate decarboxylase, or the additional exemplary self-antigens as described in Table 1. 
     In some examples, the MHC-based chimeric receptor comprises at least one co-stimulatory domain, which may be a co-stimulatory domain from 4-1BB (CD137), a co-stimulatory domain from CD28, or a combination thereof. In other examples, the MHC-based chimeric receptor as described herein may be free of a cytoplasmic signaling domain. Alternatively or in addition, the MHC-CAR comprises a cytoplasmic signaling domain of CD3ζ. 
     In some embodiments, the MHC molecule in the MHC-CAR is a class I MHC, for example, a human class I MHC. In some instances, the extracellular domain of the chimeric receptor comprises an extracellular domain of the alpha chain of the class I MHC, which is fused to the antigenic peptide. For example, the chimeric receptor may be a fusion polypeptide comprising (i) the extracellular domain of the class I MHC molecule, and (ii) the cytoplasmic domain, the at least one co-stimulatory domain, or the combination thereof. In one example, the chimeric receptor is a fusion polypeptide, which comprises, from N-terminus to C-terminus, a signal peptide, a first peptide linker, the antigenic peptide, a second peptide linker, an extracellular domain of macroglobulin, a third peptide linker, the class I MHC molecule, a transmembrane domain, the at least one co-stimulatory domain, and CD3ζ. 
     In other embodiments, the MHC-based chimeric receptor as described herein comprises a class II MHC (e.g., a human MHC II) or a portion thereof. Such a chimeric receptor may comprise a first polypeptide, which comprises an extracellular domain of a first MHC class II, and a second polypeptide, which comprises an extracellular domain of a beta chain of a second MHC class II, and wherein the antigenic peptide is fused to either the first polypeptide or the second polypeptide, and wherein either the first polypeptide or the second polypeptide further comprises the cytoplasmic signaling domain, the at least one co-stimulatory domain, or the combination thereof, in some examples, the chimeric receptor can be a fusion polypeptide comprising (i) an extracellular domain of the alpha chain of a first MHC class II molecule, (ii) an extracellular domain of the beta chain of a second MHC class II molecule, (iii) the antigenic peptide, and (iv) the cytoplasmic signaling domain, the at least one co-stimulatory domain, or the combination thereof. In some examples the antigenic protein may not be linked to the MHC class II and may instead be expressed as a separate fusion polypeptide with an alternative signal peptide (such as that from CD150, i.e., MDPKGLLSLTFVLFLSLAFG (SEQ ID NO: 388)). In some examples, the first MHC class II is HLA-DRA*1010. Alternatively or in addition, the second MHC class II is HLA-DRB1*1501. 
     In another aspect, the present disclosure features a nucleic acid or a nucleic acid set, which collectively encodes any of the MHC-based chimeric receptors described herein. In some instances, the nucleic acid or nucleic acid set can be located in one or more vectors, for example, viral vector(s). 
     Further, the present disclosure provides a genetically modified immune cell (e.g., a T cell), which expresses any of the MHC-based chimeric receptors described herein. In some instances, the activity of the endogenous T cell receptor (TCR) can be suppressed, which may be achieved by mutating or deleting the alpha chain of the endogenous TCR, the beta chain of the endogenous TCR, or both to disrupt surface expression of the endogenous TCR. Alternatively or in addition, the expression of the endogenous CD52 can be disrupted. 
     In some embodiments, the genetically modified immune cell as described herein may further express a suicide gene (e.g., RQR8), a marker gene (e.g., GFP), or both. When necessary, the immune cell can be further modified for lymph node or tertiary lymphoid organ delivery and retention. For example, the immune cell can be further engineered to overexpress VAP-1, L-selectin, CCR7, CXCR5, or a combination thereof. In some instances, the expression of endogenous sphingosine-1-phosphate receptor 1 can be disrupted in the genetically modified immune cell. 
     In some embodiments, the immune cell can be engineered to travel to the site of inflammation, for instance using a chemokine receptor such as CCR6 (e.g., to the site of Th17 cells), CXCR3 or CXCR4 (e.g., to the site of plasma cells), or through a membrane linked, antigen targeted antibody. Alternatively or in addition, the genetically modified immune cell may further comprise a genetic modification that results in blockade of PD-1 signaling. If needed and the disorder is especially severe the MHC-CAR cells can also be designed to remove or inactive bystander B cells (with a CD19 or CD20-CAR) or plasma cells (with a CS1-CAR and/or CS1 knockout). 
     In some embodiments, the genetically modified immune cell as described herein may be a regulatory T cell, which can be CD25+, and optionally CD4+. In some instances, the regulatory T cell can be derived from CD25++CD45R+ T cells isolated from peripheral blood mononuclear cells or from cord blood. In other instance, the regulatory T cell may comprise a transgene coding for CD25. Any of the Treg cells disclosed herein may further express a chimeric receptor specific to CD19, a chimeric receptor specific to CS-1, or both. Alternatively or in addition, the regulatory cell may further express CCR6, CXCR5, PD-1, or a combination thereof. In some examples, the regulatory cell may display an antibody specific to MOG. 
     In yet another aspect, the present disclosure provides a method for suppressing autoreactive immune cells in a subject having an autoimmune disease (e.g., multiple sclerosis). The method may comprise administering to the subject an effective amount of genetically modified immune cells as described herein, which can be T cells. 
     In some embodiments, the genetically modified immune cells are autologous. In other embodiments, the genetically modified immune cells are allogeneic. Any of the genetically modified immune cells may be administered to a lymph node of the subject. In some instances, the subject is undergoing a therapy comprising an antibody specific to CD52. 
     In some embodiments, the subject is a human patient having or at risk for multiple sclerosis and the genetically modified T cells are Treg cells or cytotoxic lymphocytes (CTLS) as described herein. 
     In some examples, the human patient is an early-stage MS patient and the Treg cells express the MHC-CAR and have one or more of the following genetic modifications: (i) PD-L1 and/or PD-1 knockout; (ii) surface expression of CCR6 and/or CXCR5; (iii) surface display of an antibody or an antigen-binding fragment thereof that is specific to MOG; and (iv) surface expression of a chimeric receptor targeting CD19. In some examples the patient may first, simultaneously, or alternatively be treated with cytotoxic CTLs with modifications of the same type. 
     In some examples, the human patient has relapsing-remitting MS or early-stage progressive MS and the Treg cells express the MHC-CAR and have one or more of the following modifications: (i) surface display of an antibody or antigen binding fragment that is specific to MOG; and (ii) surface expression of CCR6.

     DETAILED DESCRIPTION OF THE INVENTION 
     Autoreactive T cells, (e.g., those for myelin components involved in multiple sclerosis) exist in normal individuals. The majority of determinant of disease induction is in the class of immune response that occurs when these autoreactive T cells are triggered in autoimmune patients (e.g., in MS patients). Generation of pathologic autoreactive T cells is favored both by specific major histocompatibility complex (MHC) and non-MHC genes, which determine the protein sequences an individual reacts against and the class of the immune response. 
     Once an immune attack begins on an initial autoantigen (for example, a myelin antigen in MS), there is a spreading of reactivity to other autoantigens; that is, if a T cell attacks one autoantigen (for example, a brain protein in MS), other structures are damaged and they can sensitize additional T cells to attack other targets in a process called “epitope-spreading”, a process that is shared by all autoimmune disorders and common to disease response in general. 
     B cells are ordinary components of the immune reaction in the early disease lesion caused by initial autoreactive attacks, for example, active MS lesion as well. B cell accumulation occurs as packed aggregates or ectopic B cell follicles. Serafini et al., Brain Pathol. 14: 164-144 (2004); Wekerle, Autoimmunity, 50:1, 57-60 (2017); and Pröbstel, et al., International journal of molecular sciences, 16(7), pp. 16576-16592 (2015). In MS, B cells were reported to be found in the brain and spinal cord of RR-, SP-, and P-stage MS patients. Therapeutic treatments that target B cells either directly or indirectly have proven beneficial in treatment of autoimmune diseases such as MS. Wekerle, 2017. 
     Both CD4+ and CD8+ T cells are present in MS lesions and are believed to play a central role in disease development. Increased frequencies of myelin-reactive (MBP, PLP, and MOG) CD4 and CD8 cells are found in MS patients compared to healthy controls. Cao, et al., Sci. Transl. Med. 7 (287), 287ra74 (2014); Martin, et al., J. Exp. Med. 173 (Jan. 1, 1991); Ota, et al., Nature 346, 183 (Jul. 12, 1990); Pette, et al., Neurology 40, 1770 (1990); and Raddassi, et al., J. Immunol. 187, 1039 (2011). 
     Th1 cells producing IFN-gamma and Th17 cells are uniquely pathogenic. Factors that favor the development of Th1 cells are elevated in MS patients and are also triggered by viral infections: gamma interferon; IL-12—in almost all treatments that affect the immune system and help MS, almost all decrease Th1 response and increase Th2 and TH3 response. Th17 cells are present at sites of tissue inflammation and are implicated in autoimmune/chronic inflammatory conditions. Th17 producing CD4 and CD8 cells are increased in the lesions, blood, and CSF of patients. [Tzartos 2008; Matusevicius 1999; Bruchlacher-Waldert 2009]. The CCR6 and CD161 on Th17 cells are hypothesized to be homing molecules to inflamed tissues [Cosmi, 2008]. 
     Th17 cells are also implicated in a number of other autoimmune diseases such as sytemic lupus erythematosus, rheumatoid arthritis, juvenile idiopathic arthritis (also known as juvenile idiopathic arthritis), Sjögren&#39;s syndrome, systemic sclerosis, ankylosing spondylitis, Type 1 diabetes, autoimmune thyroid diseases (Grave&#39;s and Hashimoto&#39;s), myasthenia gravis, inflammatory bowel disease (Crohn&#39;s or ulcerative colitis), and psoriasis. Tabarkiewicz et al., Archivum immunologiae et therapiae experimentalis, 63(6):435-449 (2015). 
     The ultimate goal of any treatment for autoimmune disease is a complete suppression of pathology. In the case of multiple sclerosis and other autoimmune disorders, pathologic lymphocytes (both B and T cells, and if necessary plasma cells for very severe cases) are expected to be eliminated or controlled to halt the disease course, and interventions at different stages of disease progression require different cellular targets and therefore therapeutic cells. 
     Disclosed herein are major histocompatibility complex (MHC)-based chimeric receptors (MHC-CAR) for targeting autoreactive immune cells such as autoreactive T cells. A MHC-CAR as described herein comprises one or more MHC polypeptides or an extracellular domain thereof and one or more cell signaling domains, for example, a cytoplasmic signaling domain (e.g., that from CD3ζ), at least one co-stimulatory domain (e.g., that from 4-1BB or CD28), or both. The MHC-CAR may further comprise an antigenic peptide from an autoantigen or a foreign antigen that mimics an autoantigen in eliciting autoimmune responses. Also herein are nucleic acids encoding the MHC-CAR, vectors carrying such, and genetically engineered immune cells such as T cell and natural killer (NK) cells expressing the MHC-CAR. Such genetically engineered immune cells can be used to target autoreactive immune cells, thereby benefiting treatment of autoimmune diseases involving the autoreactive immune cells. 
     Also disclosed herein are genetically modified regulatory T (Treg) cells expressing an MHC-based chimeric receptor as disclosed herein. Such Treg cells may be further modified with chimeric receptor(s) targeting T cell and/or B cell surface markers, as well as additional genetic engineering for, e.g., targeting specific tissue sites (e.g., lymph nodes or inflammation sites) or modulating immune responses e.g., checkpoint modulation). The genetically modified Treg cells may be used to inhibit pathogenicity at an early stage of a target disease, to control disease progression at a middle stage of the disease (e.g., relapsing or remitting MS), or to suppress pathology via, e.g., inducing cytotoxicity of pathologic CD8+ T cells at a late stage of the disease chronic progressive MS). 
     I. Major Histocompatibility Complex (MHC)-Based Chimeric Receptors (MHC-CARS) 
     The MHC based chimeric receptor (MHC-CAR) described herein comprises an MHC moiety, which is conjugated to an antigenic peptide (e.g., a misfolded one), and at least one cell signaling moiety, which can be a cytoplasmic signaling domain (e.g., that of CD3ζ), one or more co-stimulatory domains (e.g., that of 4-1BB or CD28), or a combination thereof. In some instances, the antigenic peptide can be part of a fusion polypeptide of the MHC-CAR. In other instances, the antigenic peptide does not form a fusion polypeptide with the MHC-CAR but forms a complex with the MHC-CAR. As used herein, the term “conjugated” means that at least two components are physically associated, either Via covalent bonds or Via non-covalent interactions. 
     In some examples, the MHC-CAR can be a single fusion polypeptide containing the MHC moiety, the antigenic peptide, and the at least one cell signaling moiety. Such a single fusion polypeptide may form complexes with endogenous cell membrane proteins (e.g., β-microglobulin) when expressed in a suitable immune cells. 
     In other examples, the MHC-CAR described herein may be a multi-chain protein complex, for example, a heterodimer, comprising one polypeptide that comprises the antigenic peptide. In some instances, the antigenic peptide or polypeptide may be expressed as a separate polypeptide, which may form a complex (e.g., a trimer) with the MHC components. The antigenic polypeptide can be a misfolded antigenic protein that binds to the MHC. Optionally, the MHC-CAR may further comprise a hinge domain, which may be adjacent to the antigenic peptide and/or the MHC moiety, a signal peptide at the N-terminus, and/or one or more tagging sites, for example, a histidine protein tag and/or an RQR domain that additionally acts as a kill-switch site. 
     (i) Components of MHC-CARs 
     (a) MHC Moiety 
     The MHC-CAR constructs disclosed herein comprise an MHC moiety, which may comprise one or more MHC polypeptides or an extracellular domain thereof. The MHC moiety may be derived from a suitable source, for example, human or a non-human mammal (e.g., monkey, mouse, rat, rabbit, pig, etc.) In some instances, the MHC moiety is from a human MHC molecule (also known as HLA). In some instances the domains that interact with molecules from other cells (TCR or BCR) are from a human MHC molecule. There are primarily two classes of MHC molecules, MHC class I molecules and WIC class II molecules, both of which can be used for constructing the MHC-CARs described herein. Sequences of MHC class I and class II molecules of various species (e.g., human, non-human primates, canids, fish, ovids, bovines, equids, suids, murids, and gallus) are available from public gene datasets, for example, the IPD-MHC database and the IMGT/HLA database provided by EMBL-EBI and the dbMHC database provided by National Center for Biotechnology Information (NCBI). 
     MHC class I molecules are heterodimers containing an alpha chain and β-microglobulin. The extracellular domain of an alpha chain includes three subdomains, α1, α2, and α3. In some embodiments, the MHC moiety may include the alpha chain of a MHC class I molecule, or an extracellular domain thereof, for example, the α1 domain, the α2 domain, the α3 domain, or a combination thereof. The MHC class I molecule may be a human HLA-A molecule, a human HLA-B molecule, or a human HLA-C molecule. In some instances, the alpha chain of the MHC class I molecule may be fused with β-microglobulin to produce a single chain fusion protein. In some examples, the MHC Class I moiety is from HLA A3, which can be co-used with a PLP peptide. Honma et al., J. Neuroimmunol. 73:7-14 (1997). In other examples, the MHC Class I is from HLA A2, which can be used with the same PLP peptide and display of a viral peptide such as TAX. TAX is from the protein tax or p40 (Genhank accession no. BAB20130.1) that is a molecular mimic of a human neuronal protein and from the HTLV-1 virus, which is implicated in diseases such as rheumatoid arthritis, system lupus erythematosus, and Sjogren&#39;s syndrome. Garboczi, et al. The Journal of Immunology, 157(12):5403-5410, 1996. Quaresma, et al., 2015. Viruses, 8(1):5 2015. The class I protein and peptide may additionally contain modifications to enable more robust peptide loading such replacement of the invariant tyrosine at position 84 of the heavy chain with alanine; or alternatively the position 84 tyrosine can be replaced with cysteine as can the second position of the peptide-β2m linker to create a disulfide trap. Hansen et al.  Trends in immunology,  31(10):363 (2010). 
     Like MHC class I molecules, MHC class II molecules are also heterodimers consisting of two homogenous peptides, an α-chain and a β-chain. The extracellular domain of each of the α-chain and the β-chain contains two subdomains α1/α2, and β1/β2. When a MHC class II molecule is used for constructing a MHC-CAR, the MHC moiety may include two subunits, one including the α-chain or a portion thereof, for example, an extracellular domain thereof (e.g., α1, α2, or both), the other including the b-chain or a portion thereof, for example, an extracellular domain thereof (e.g., β1, β2, or both). In cases where only the region that interacts with other cell types is used (i.e., α1 and β1), specific amino acid modifications may be required to enhance the folding of the mini-MHC, see mini-sequence with shaded regions and Birnbaum et al. The MHC class II molecule may be a human HLA DP molecule, a human HLA DM molecule, a human HLA DOA molecule, a human HLA DOB molecule, a human HLA DQ molecule, or a human HLA DR molecule. In some examples, the MHC class II molecule is a human HLA DR molecule, for example HLA DR*1501. 
     (b) Antigenic Peptides 
     The antigenic peptides of the MHC-CAR described herein are an antigenic peptide that is recognizable by pathogenic immune cells (e.g., autoreactive T cells or B cells) involved in an autoimmune disease. When presented by a suitable MHC molecule, such an antigenic peptide would interact with the antigen-specific T cell receptors of pathogenic T cells, leading to downstream immune responses. 
     In some instances, a specific antigenic peptide can be designed for a specific autoimmune disease patient such as an MS patient, using methods known in the art. Programs like NetMHC enable personalized design of antigenic peptides that are specific to the patients MHC, and have been used to develop personalized cancer vaccines. Hacohen et al., Cancer immunology research, 1(1):11-15 (2013). Also within the scope of the present disclosure are personalized CAR T and Treg therapies for autoimmune disorders. For disorders with very strong MHC associations (such as MS), a personalized therapy can be utilized to treat a large patient class at different stages of the disease. Recent studies have also demonstrated that Class II MHCs and specifically the HLAs implicated in autoimmune disorders can display entire antigenic proteins rather than just processed peptides. Jiang et al., International immunology, 25(4):235-246, (2013). These MHC-protein complexes appear to induce autoantibody production in autoimmune disorders, including antibodies that do not bind to properly folded proteins as well as autoantibodies that are specific to those with specific autoimmune disorders. The inventors impute that display of antigenic proteins in MHC-CAR can provide a specific route to remove or deactivate autoimmune specific B cells, such as those in MS which produce oligoclonal bands whose specificity to proteins has not been unraveled, despite many rigorous attempts. Owens et al., Annals of neurology, 65(60):639-649, 2009; Chastre et al., New England Journal of Medicine, 374(15):1495-1496, 2016; Housley et al., Clinical immunology, 161(1):51-58, 2015; Larman et al., 2013. Journal of autoimmunity, 43:1-9, 2013. In the event that the antigenic protein does not bind the MHC, then that specific MHC-CAR will not be expressed, but as a Treg or CTL it can still play a bystander role in modifying the immune response depending upon its other characteristics and as part of a patient specific population of MHC-CAR and Treg cells with different specificities. 
     The antigenic peptides used herein may be fragments of autoantigens involved in autoimmune diseases, for example, myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG), and proteolipid protein (PLP) involved in multiple sclerosis, insulin and glutamate decarboxylase (GAD) involved in type I diabetes, tryptase involved in rheumatoid arthritis (RA), and the proteins included in Table 1 below. Alternatively, the antigenic peptide can be a fragment of a pathogen protein such as a viral or a bacterial protein that is highly homologous to a self-antigen involved in an autoimmune disease. Such an antigenic peptide also can target pathogenic T cells. If needed, the antigenic peptide can be a (typically misfolded) antigenic protein or protein fragment that can be expressed separately and binds directly to the MHC moiety of a MHC-CAR described herein. In their natural state (attached to an MHC rather than an MHC moiety of a MHC-CAR), such antigenic protein/MHC complexes stimulate pathogenic B cells to produce autoantibodies. For proteins such as IgGH or rheumatoid factor in rheumatoid arthritis (Jin et al.,  Proceedings of the National Academy of Sciences,  111(10):3787-3792, 2014), β2-glycoprotein I in antiphospholipid syndrome (Tanimura et al.,  Blood,  25(142835-2844, 2015) and recurrent miscarriage (Tanimura et al.,  Placenta,  46:108, 2016), GM-CSF in autoimmune pulmonary alveolar proteinosis (Hamano et al.,  ALVEOLAR MACROPHAGE BIOLOGY  B32: A3147-A3147, 2016), tyrosinase in vitiligo (Arase et al.  Journal of Dermatological Science,  84(1):e87, 2016), and myeloperoxidase in microscopic polyangiitis (Hiwa et al.,  Arthritis  &amp;  Rheumatology,  69(10):2069-2080, 2017), HLA mediated surface display and in some cases autoantibody binding of misfolded variant/HLA complex can occur. 
     The antigenic peptides for use in the MHC-CAR described herein may contain up to 20 amino acid residues, the extracellular domain of the antigenic protein, or the full length antigenic protein. When co-used with a MHC class I moiety, the antigenic peptide may be 8-10 amino acid-long. Such antigenic peptides would fit well into the peptide binding site of a MHC class I molecule. Antigenic peptides to be co-used with MHC class II moieties can be longer, for example, containing 15-24 amino acid residues or up to the full length of the antigenic protein, since the antigen-binding groove of MHC class II molecules is open at both ends, while the corresponding antigen-binding groove on class I molecules is usually closed at each end. The open antigen-binding groove of MHC class II molecules implicated in autoimmune disorders can also frequently display intact (e.g., yet misfolded) antigenic proteins or splice variants.

     In some examples, a fragment of human MBP is used for constructing the MHC-CARs described herein. An exemplary amino acid sequence of a human MBP is provided below:

     In some embodiments, the antigenic peptides or antigenic polypeptides are patient specific and designed for the patient&#39;s MHC. For example, a physician can diagnose the patient with an autoimmune disorder and determine the severity of the disease. The patient&#39;s Class I (HLA-A, B, and C) and II (HLA-DR, DQ, DP) regions can be typed, which can now be performed at high resolution using DNA sequencing and with comparison to a reference database (www.ebi.ac.uk/ipd/imgt/hla/). The patient&#39;s Class I and II MHC with the strongest evidence of autoimmune involvement can be identified for the disorder. Those known to be associated with a particular autoimmune disorder can be used as references. See, e.g., Tables 1 and 2. The strongest evidence based antigens are identified for the disorder (iedb.org/) and Table 1. A set of personalized peptide (cbs.dtu.dk/services/NetMHC/ or cbs.dtu.dk/services/NetMHCII/) and protein targets (for Class II) that are expected to bind the patient autoimmune implicated MHC can be identified. 
     Personalized MHC-CABs lentivirus or mRNA can be prepared for the patient to enable targeting of pathogenic immune cells. The personalized lentivirus is used to prepare autologous or allogeneic T cells (CTL and/or Tregs) that can be combined with receptor or cellular modifications to allow co-treatment with additional therapeutics, desired interactions with pathogenic cells, routing to a desired location (for interaction with pathogenic inflammatory or inflammation generating cells), or secretion of cytokines (to reduce inflammation). 
     (c) Co-Stimulatory Signaling Domains 
     Many immune cells require co-stimulation, in addition to stimulation of an antigen-specific signal, to promote cell proliferation, differentiation and survival, as well as to activate effector functions of the cell. The WIC-CAR described herein may comprise one or more co-stimulatory signaling domain. The term “co-stimulatory signaling domain,” as used herein, refers to at least a portion of a protein that mediates signal transduction within a cell to induce an immune response such as an effector function. The co-stimulatory signaling domain of the MHC-CAR described herein can be a cytoplasmic signaling domain from a co-stimulatory protein, which transduces a signal and modulates responses mediated by immune cells, such as T cells, NK cells, macrophages, neutrophils, or eosinophils. 
     Activation of a co-stimulatory signaling domain in a host cell (e.g., an immune cell) may induce the cell to increase or decrease the production and secretion of cytokines, phagocytic properties, proliferation, differentiation, survival, and/or cytotoxicity. The co-stimulatory signaling domain of any co-stimulatory molecule may be compatible for use in the MHC-CAR described herein. Examples of co-stimulatory signaling domains for use in the chimeric receptors can be the cytoplasmic signaling domain of co-stimulatory proteins, including, without limitation, members of the B7/CD28 family (e.g., B7-1/CD80, B7-2/CD86, B7-H1/PD-L1, B7-H2, CD28, CTLA-4, ICOS/CD278, or PD-1); members of the TNF superfamily (e.g., 4-1BB/TNFSF9/CD137, 4-1BB Ligand/TNFSF9, CD40/TNFRSF5, CD40 Ligand/TNFSF5, DR3/TNFRSF25, OX40/TNFRSF4, OX40 Ligand/TNFSF4, or TNF-alpha); and other molecules, such as FRB, and FKBF, that allow co-stimulation to be induced only in the presence of a specific drug molecule (but here in association with a the unique heterodimeric MHC-CAR). Wu et al.,  Science,  350(6258):aab4077, 2015. In some embodiments, any of the cytoplasmic signaling domains of co-stimulatory proteins may be used in receptors targeting inactive bystander B cells (e.g., with a CD19 or CD20-CAR) or plasma cells (e.g., with a CS1-CAR and/or CS1 knockout). 
     In some instances, the MHC-CAR may comprise a combination (e.g., 2 or 3) co-stimulatory domains, which may be from the same co-stimulatory receptor or from different co-stimulatory receptors. Examples include: CD28+4-1BB, CD28+FRB, CD28+FKBF, or 4-1BB+FRB. See also  FIG. 9 . In some examples, the MHC-CAR comprises a co-stimulatory domain from CD28, a co-stimulatory domain from 4-1BB, or both. In some embodiments, the co-stimulatory domain is preceded by a short linker. For example, for a class H MHC-CAR, the short linker may be TS (i.e., a MHC internal Linker); for a class I MHC-CAR, the short linker may be PG. 
     In some instances, the MHC-CAR constructs described herein may include no co-stimulatory domain. Alternatively, it may contain a non-traditional element such as a TALEN nuclease, activators, or repressors which may now be implemented in a clinically applicable lentiviral form using a recoded or non-repeat containing TAL domain and would be linked to a single chain MHC-CAR through a membrane domain derived from Notch. 
     Exemplary co-stimulatory domains for use in the MHC-CAR described herein include, but are not limited to:

     (d) Cytoplasmic Signaling Domain 
     Any cytoplasmic signaling domain comprising an immunoreceptor tyrosine-based activation motif (ITAM) can be used to construct the chimeric receptors described herein. An “ITAM,” as used herein, is a conserved protein motif that is generally present in the tail portion of signaling molecules expressed in many immune cells. The motif may comprises two repeats of the amino acid sequence YxxL/I separated by 6-8 amino acids, wherein each x is independently any amino acid, producing the conserved motif YxxL/Ix(6-8)YxxL/I. In some examples, the cytoplasmic signaling domain comprising an ITAM is of CD3ζ. In some examples, the MHC-CAR does not comprise a co-stimulatory domain and the cytoplasmic signaling domain is preceded by a short linker. For example, for a class II MHC-CAR, the short linker may be TS (i.e., a MHC internal Linker). For example for a class I MHC-CAR, the short linker may be PG. In some cases the linker may be AHA or absent, such as certain instances when a co-stimulatory domain occurs before a signaling domain. 
     In some embodiments, the MHC-CAR may include no cytoplasmic signaling domain, for example, that of CD3ζ. Such CD3ζ-free MHC-CAR would have suppressive effects against target cells or induce target cell death. Moisini, et al., The Journal of Immunology, 180(5), pp. 3601-3611.

     (e) Additional Components 
     The MHC-CAR described herein may optionally further include one or more of the following components: a hinge domain, a transmembrane domain, a signal (leader) peptide, and a peptide linker. 
     In some instances, the antigenic peptide may be linked to a hinge peptide to enhance immune targeting activity of the resultant MHC-CAR and/or to reduce antibody responses by the target cell to the MHC-TCR complex. In some examples, a MHC-CAR containing a hinge peptide may not include a cytoplasmic domain (for example, free of a CD3ζ domain). A MHC-CAR construct that contains a hinge peptide may also include a MHC class I moiety. The hinge domain may contain about 10-100 amino acids, e.g., 15-75 amino acids, 20-50 amino acids, or 30-60 amino acids. In some embodiments, the hinge domain may be of 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50, 55, 60, 65, 70, or 75 amino acids in length. 
     In some examples, the following peptide linkers can be used in a class I MHC-CAR:

     A hinge peptide for use in the MHC-CAR described herein may be derived from a naturally-occurring receptor. Hinge domains of any protein known in the art to comprise a hinge domain are compatible for use in the chimeric receptors described herein. In some embodiments, the hinge domain is a portion of the hinge domain of CD8α, e.g., a fragment containing at least 15 (e.g., 20, 25, 30, 35, or 40) consecutive amino acids of the hinge domain of CD8a.

     In some embodiments, the MHC-CAR constructs described herein further comprise a transmembrane domain. Any transmembrane domain for use in the MHC-CAR can be in any form known in the art. As used herein, a “transmembrane domain” refers to any protein structure that is thermodynamically stable in a cell membrane, preferably a eukaryotic cell membrane. Transmembrane domains compatible for use in the chimeric receptors used herein may be obtained from a naturally-occurring protein. Alternatively, it can be a synthetic, non-naturally occurring protein segment, e.g., a hydrophobic protein segment that is thermodynamically stable in a cell membrane. 
     Transmembrane domains are classified based on the three dimensional structure of the transmembrane domain. For example, transmembrane domains may form an alpha helix, a complex of more than one alpha helix, a beta-barrel, or any other stable structure capable of spanning the phospholipid bilayer of a cell. Furthermore, transmembrane domains may also or alternatively be classified based on the transmembrane domain topology, including the number of passes that the transmembrane domain makes across the membrane and the orientation of the protein. For example, single-pass membrane proteins cross the cell membrane once, and multi-pass membrane proteins cross the cell membrane at least twice (e.g., 3, 4, 5, 6, 7 or more times). 
     Membrane proteins may be defined as Type I, Type II or Type III depending upon the topology of their termini and membrane-passing segment(s) relative to the inside and outside of the cell. Type I membrane proteins have a single membrane-spanning region and are oriented such that the N-terminus of the protein is present on the extracellular side of the lipid bilayer of the cell and the C-terminus of the protein is present on the cytoplasmic side. Type II membrane proteins also have a single membrane-spanning region but are oriented such that the C-terminus of the protein is present on the extracellular side of the lipid bilayer of the cell and the N-terminus of the protein is present on the cytoplasmic side. Type III membrane proteins have multiple membrane-spanning segments and may be further sub-classified based on the number of transmembrane segments and the location of N- and C-termini. 
     In some embodiments, the transmembrane domain of the MHC-CAR described herein is derived from a Type I single-pass membrane protein, e.g., CD8α, CD8β, 4-1BB/CD137, or CD28. Transmembrane domains from multi-pass membrane proteins may also be compatible for use in the chimeric receptors described herein. Multi-pass membrane proteins may comprise a complex (at least 2, 3, 4, 5, 6, 7 or more) alpha helices or a beta sheet structure. Preferably, the N-terminus and the C-terminus of a multi-pass membrane protein are present on opposing sides of the lipid bilayer, e.g., the N-terminus of the protein is present on the cytoplasmic side of the lipid bilayer and the C-terminus of the protein is present on the extracellular side. Either one or multiple helix passes from a multi-pass membrane protein can be used for constructing the chimeric receptor variant described herein.

     In some embodiments, the MHC-CAR may also comprise a signal peptide (also known as a signal sequence or a leader peptide) at the N-terminus of the polypeptide. In general, signal sequences are peptide sequences that target a polypeptide to the desired site in a cell. In some embodiments, the signal sequence targets the MHC-CAR to the secretory pathway of the cell and will allow for integration and anchoring of the MHC-CAR into the lipid bilayer. Signal sequences including signal sequences of naturally occurring proteins or synthetic, non-naturally occurring signal sequences, that are compatible for use in the chimeric receptors described herein will be evident to one of skill in the art. In some embodiments, the signal sequence from CD8α. In some embodiments, the signal sequence is from CD28 (e.g., MLRLLLALNLFPSIQVTG (SEQ ID NO: 97)). 
     Exemplary signal peptides include, but are not limited to, Beta-2-microglobulin signal peptide (e.g., MSRSVALAVLALLSLSGLEA (SEQ ID NO: 98)), HLA A3 signal peptide (e.g., MAVMAPRTLLLLLSGALALTQTWA (SEQ ID NO: 99) or), DRA*0101 signal peptide (e.g., MAISGVPVLGFFIIAVLMSAQESWA (SEQ ID NO: 100)), DRB1*1501 signal peptide (e.g., MVCLKLPGGSCMTALTVTLMVLSSPLAL (SEQ ID NO: 101)), and DRBS signal peptide (e.g., MVCLKLPGGSYMAKLTVTLMVLSSPLALA (SEQ ID NO: 102)). Exemplary signal peptides may be followed by flexible pre-peptide linkers such as AS, GS, ASAS, GSGS. In some embodiments, a flexible pre-peptide linker is used when the signal peptide is class II and followed by an introduced peptide. Any of the constructs encoding the MHC-CARs described herein may comprise a nucleic acid sequence encoding any of the pre-peptide linkers above, e.g. AS may be encoded by the nucleic acid sequence GCATCT, TS may be encoded by the nucleic acid sequence ACAAGT.

     In some embodiments, the MHC-CAR described herein may include one or more peptide linkers between the other components as described herein. Examples include a (Gly x Ser) n  linker, wherein x and n, independently can be an integer between 3 and 12, including 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, or more. In some examples, the peptide linker can be (Gly 4 Ser) n  (SEQ ID NO: 103), wherein n can be an integer between 3 and 20. Specific examples include (Gly 4 Ser) 3  (SEQ If) NO: 68), (Gly 4 Ser) 6  (SEQ ID NO: 69), (Gly 4 Ser) 9  (SEQ ID NO: 76), (Gly 4 Ser) 12  (SEQ ID NO: 105), and (Gly 4 Ser) 15  (SEQ ID NO: 106). 
     (ii) Configuration of MHC-CARs 
     The MHC-CAR constructs disclosed herein, comprising one or more components described herein, may be configured in any suitable format. Exemplary WIC class I constructs and MHC class II constructs are provided in  FIGS. 7 and 8 . 
     A MHC-CAR construct containing a MHC class I moiety as described herein may be a single fusion polypeptide that comprise the MHC class I moiety, the antigenic peptide, and a signaling domain (e.g., a co-stimulatory domain, a cytoplasmic signaling domain, or a combination thereof), and optionally one or more of the additional components described herein. See, e.g.,  FIG. 8 . In some examples, a MHC Class I CAR construct contains a hinge domain adjacent to the antigenic peptide. A MHC class I CAR may not contain β2-microglobulin (b2m). When expressed on cell surface, such a MHC-CAR may form a heterodimer with endogenous b2m. Alternatively, a MHC class I CAR may also include b2m, which may be fused with the alpha chain to produce a single polypeptide. In some instances, a MHC class I CAR may contain two subunits, one including the alpha chain or a portion thereof (e.g., an extracellular domain), and the other including b2m or a portion thereof (e.g., an extracellular domain). In some examples, the antigenic peptide may be fused to the alpha chain. In other examples, the antigenic peptide may be fused to b2m. Optionally, a MHC class I CAR may contain peptide linkers between two components. One example is provided in  FIG. 8B . 
     In some examples, the MHC-CAR comprises a class I molecule or a portion thereof, for example, HLA A3 or HLA A2, and a antigenic peptide suitable for presentation by the class I molecule (e.g., the PLP fragment KLIETYFSK (SEQ ID NO: 107) or the TAX fragment LLFGYPVYV (SEQ ID NO: 108)). Optionally, the MHC-CAR may further comprise b2m. Alternatively, the b2m molecule may be expressed separately from the class I MHC-CAR. Examples of the class I molecules and b2m sequences are provided below:

       FIG. 7  provides a number of exemplary designs of MHC class II CAR constructs. Typically, a MHC class II CAR construct contains two subunits, one including the alpha chain or a portion thereof (e.g., an extracellular domain) and the other including the beta chain or a portion thereof (e.g., an extracellular domain). The antigenic peptide can be fused to either the alpha chain or the beta chain. In some instances, a MHC class II CAR can also be in a single fusion polypeptide format, in which the alpha and beta chains are fused to form a single polypeptide. The alpha chain and beta chain of a MHC class II CAR may be derived from the same MHC class II molecule. Alternatively, they may be from different WIC class II molecules. For example, a MHC class II CAR may contain an alpha chain from HLA DRA*1010 and a beta chain from HLA DRB1*1501, which may be fused with an antigenic peptide, such as an MBP peptide. 
     In some examples, the MHC-CAR comprises a class II molecule or a portion thereof, for example, DRB1*1501 or DRA*0101, and a antigenic peptide suitable for presentation by the class II molecule (e.g., the MBP fragment DENPVVHFFKNIVTPRTPP (SEQ ID NO: 15)).

     Any of MHC class I and MHC class II constructs described herein can be further fused to one or more signaling domains and optionally one or more of the additional components. In some instances, the MHC-CAR constructs described herein are free of singling domains. 
     Preferably, a MHC-CAR as described herein contains matched MHC moiety and antigenic peptide, e.g., a MHC molecule that would present the antigenic peptide or homologous analogs in natural state. In some instances, a MHC-CAR described herein may contain an alpha chain or a beta chain from HLA DRB1*1501 and an antigenic peptide associated with this HLA allele, e.g., those MBP peptides described herein and others as well. The association between antigenic peptides involved in an autoimmune disease and a specific HLA allele is well known in the art or can be identified via routine practice, for example, library screening. 
     One exemplary MHC-CAR may have the following formula (+/− means that the specific component is optional): 
       Single chain (MHC Class I or II+peptide) (+/−hinge)+single chain CD28/4-1BB (+/−dileucine motifs) (+/−cd3zeta)). (Additional short peptide linkers can be added between components as described previously.)
 
     Other exemplary MHC-CAR designs (single chain and multi-chain) are illustrated in  FIG. 10 . In the case of multi-chain constructs, one or more short hinges may be used to enhance successful expression of the MHC-CAR. Further, it may be desirable to replace a portion of the structure with conserved domains from mice domains to prevent cross-reactivity. Note that in some cases, the internal domain may only be attached to one of the chains.

     (iii) Preparation of MHC-CARs 
     Any of the MHC-CAR constructs described herein can be prepared by a routine method, such as recombinant technology. Methods for preparing the chimeric receptors herein involve generation of a nucleic acid or a nucleic acid set that encodes or collectively encodes a MHC-CAR construct (including a single polypeptide or two subunits). In some embodiments, the nucleic acid also encodes a self-cleaving peptide (e.g., P2A, T2A, or E2A peptide) between the coding sequences for the two subunits of a MHC-CAR, or between the coding sequence for a MHC-CAR and the coding sequence for other genes to be co-expressed with the MHC-CAR in a host cell (see discussions below). 
     Sequences of each of the components of the MHC-CARS may be obtained via routine technology, e.g., PCR amplification from any one of a variety of sources known in the art. In some embodiments, sequences of one or more of the components of the MHC-CARs are obtained from a human cell. Alternatively, the sequences of one or more components of the MHC-CARS can be synthesized. Sequences of each of the components (e.g., domains) can be joined directly or indirectly (e.g., using a nucleic acid sequence encoding a peptide linker) to form a nucleic acid sequence encoding the MHC-CAR, using methods such as PCR amplification or ligation. Alternatively, the nucleic acid encoding the MHC-CAR may be synthesized. In some embodiments, the nucleic acid is DNA. In other embodiments, the nucleic acid is RNA. 
     Any of the MHC-CAR proteins, nucleic acid encoding such, and expression vectors carrying such nucleic acid, all of which are within the scope of the present disclosure, can be mixed with a pharmaceutically acceptable carrier to form a pharmaceutical composition, which is also within the scope of the present disclosure. “Acceptable” means that the carrier is compatible with the active ingredient of the composition (e.g., the nucleic acids, vectors, cells, or therapeutic antibodies) and does not negatively affect the subject to which the composition(s) are administered. Any of the pharmaceutical compositions to be used in the present methods can comprise pharmaceutically acceptable carriers, excipients, or stabilizers in the form of lyophilized formations or aqueous solutions. 
     Pharmaceutically acceptable carriers, including buffers, are well known in the art, and may comprise phosphate, citrate; and other organic acids; antioxidants including ascorbic acid and methionine; preservatives; low molecular weight polypeptides; proteins, such as serum albumin, gelatin, or immunoglobulins; amino acids; hydrophobic polymers; monosaccharides; disaccharides; and other carbohydrates; metal complexes; and/or non-ionic surfactants. See, e.g. Remington: The Science and Practice of Pharmacy 20th Ed. (2000) Lippincott Williams and Wilkins, Ed. K. E. Hoover. 
     II. Genetically Engineered Immune Cells Expressing MHC-CARs 
     (i) MHC-CAR-Expressing Immune Cells 
     Immune cells expressing the MHC-CAR described herein provide a specific population of cells that can recognize pathogenic cells (e.g., autoreactive T cells) involved in autoimmune diseases via MHC/peptide-TCR engagement. The interaction between the MHC-peptide portion of the MHC-CAR and the cognate TCR on the pathogenic cells would activate the MHC-CAR expressing immune cells via the signaling domains(s) of the MHC-CAR (optionally by recruiting cell membrane signaling molecules of the immune cells), leading to proliferation and/or effector functions of the MHC-CAR-expressing immune cells, which in turn eliminate the pathogenic cells. The immune cells can be T cells, NK cells, macrophages; neutrophils, eosinophils, or any combination thereof. In some embodiments, the immune cells are T cells. In some embodiments, the immune cells are NK cells. Specific examples are provided in Examples below. 
     The population of immune cells can be obtained from any source, such as peripheral blood mononuclear cells (PBMCs), hone marrow, tissues such as spleen, lymph node, thymus, tumor tissue, or established cell lines. A source suitable for obtaining the type of immune cells desired would be evident to one of skill in the art. In some embodiments, the population of immune cells is derived from PBMCs. The type of immune cells desired (e.g., T cells, NK cells, macrophages, neutrophils, eosinophils, or any combination thereof) may be expanded within the population of cells obtained by co-incubating the cells with stimulatory molecules, for example, anti-CD3 and anti-CD28 antibodies may be used for expansion of T cells. 
     To construct the immune cells that express any of the MHC-CAR constructs described herein, expression vectors for stable or transient expression of the chimeric receptor construct may be constructed via conventional methods as described herein and introduced into immune host cells. For example, nucleic acids encoding the MHC-CAR may be cloned into a suitable expression vector, such as a viral vector (e.g., a lentiviral vector) in operable linkage to a suitable promoter. The nucleic acids and the vector may be contacted, under suitable conditions, with a restriction enzyme to create complementary ends on each molecule that can pair with each other and be joined with a ligase. Alternatively, synthetic nucleic acid linkers can be ligated to the termini of the nucleic acid encoding the chimeric receptors. The synthetic linkers may contain nucleic acid sequences that correspond to a particular restriction site in the vector. The selection of expression vectors/plasmids/viral vectors would depend on the type of host cells for expression of the chimeric receptors, but should be suitable for integration and replication in eukaryotic cells. 
     A variety of promoters can be used for expression of the MHC-CAR constructs described herein, including, without limitation, cytomegalovirus (CMV) intermediate early promoter, a viral LTR such as the Rous sarcoma virus LTR, HIV-LTR, HTLV-1 LTR, the simian virus 40 (SV40) early promoter, herpes simplex tk virus promoter. Additional promoters for expression of the chimeric receptors include any constitutively active promoter in an immune cell. Alternatively, any regulatable promoter may be used, such that its expression can be modulated within an immune cell. 
     Additionally, the vector may contain, for example, some or all of the following: a selectable marker gene, such as the neomycin gene for selection of stable or transient transfectants in host cells; enhancer/promoter sequences from the immediate early gene of human CMV for high levels of transcription; transcription termination and RNA processing signals from SV40 for mRNA stability; SV40 polyoma origins of replication and ColE1 for proper episomal replication; internal ribosome binding sites (IRESes), versatile multiple cloning sites; T7 and SP6 RNA promoters for in vitro transcription of sense and antisense RNA; a “suicide switch” or “suicide gene” which when triggered causes cells carrying the vector to die (e.g., HSV thymidine kinase, an inducible caspase such as iCasp9), and reporter gene for assessing expression of the MHC-CAR. 
     In some embodiments, the marker/sorting/suicide molecules for use in the present disclosure can be used for killing with rituximab and/or for sorting with QBEND. Philip et al., Blood 124(8):1277-87; 2014). One example is RQR8, which contains rituximab mimotope and QBEND-10 epitope.

     The boldfaced fragment is the rituximab minotope and the underlined/italicized fragment is the QBEND-10 epitope. 
     Suitable vectors and methods for producing vectors containing transgenes are well known and available in the art. Any of the vectors comprising a nucleic acid sequence that encodes a MHC-CAR construct described herein is also within the scope of the present disclosure. Such a vector may be delivered into host immune cells by a suitable method. Methods of delivering vectors to immune cells are well known in the art and may include DNA electroporation, RNA electroporation, transfection reagents such as liposomes, or viral transduction. In some embodiments, the vectors for expression of the MHC-CAR are delivered to host cells by viral transduction. Exemplary viral methods for delivery include, but are not limited to, recombinant retroviruses (see, e.g., PCT Publication Nos. WO 90/07936; WO 94/03622; WO 93/25698; WO 93/25234; WO 93/11230; WO 93/10218; WO 91/02805; U.S. Pat. Nos. 5,219,740 and 4,777,127; GB Patent No. 2,200,651; and EP Patent No. 0 345 242), alphavirus-based vectors, and adeno-associated virus (AAV) vectors (see, e.g., PCT Publication Nos. WO 94/12649, WO 93/03769; WO 93/19191; WO 94/28938; WO 95/11984 and WO 95/00655). In some embodiments, the vectors for expression of the chimeric receptors are retroviruses. In some embodiments, the vectors for expression of the chimeric receptors are lentiviruses. 
     In examples in which the vectors encoding chimeric receptors are introduced to the host cells using a viral vector, viral particles that are capable of infecting the immune cells and carry the vector may be produced by any method known in the art and can be found, for example in PCT Application No. WO 1991/002805A2, WO 1998/009271 A1, and U.S. Pat. No. 6,194,191. The viral particles are harvested from the cell culture supernatant and may be isolated and/or purified prior to contacting the viral particles with the immune cells. 
     Following introduction into the host cells a vector encoding any of the MHC-CAR provided herein, the cells are cultured under conditions that allow for expression of the chimeric receptor. In examples in which the nucleic acid encoding the MHC-CAR is regulated by a regulatable promoter, the host cells are cultured in conditions wherein the regulatable promoter is activated. In some embodiments, the promoter is an inducible promoter and the immune cells are cultured in the presence of the inducing molecule or in conditions in which the inducing molecule is produced. Determining whether the MHC-CAR is expressed will be evident to one of skill in the art and may be assessed by any known method, for example, detection of the chimeric receptor-encoding mRNA by quantitative reverse transcriptase PCR (qRT-PCR) or detection of the chimeric receptor protein by methods including Western blotting, fluorescence microscopy, and flow cytometry. See also Examples below. Alternatively, expression of the MHC-CAR may take place in vivo after the immune cells are administered to a subject. 
     Alternatively, expression of a MHC-CAR construct in any of the immune cells disclosed herein can be achieved by introducing RNA molecules encoding the MHC-CAR constructs. Such RNA molecules can be prepared by in vitro transcription or by chemical synthesis. The RNA molecules can then introduced into suitable host cells such as immune cells (e.g., T cells, NK cells, macrophages, neutrophils, eosinophils, or any combination thereof) by, e.g., electroporation. For example, RNA molecules can be synthesized and introduced into host immune cells following the methods described in Rabinovich et al., Human Gene Therapy, 17:1027-1035 and WO WO2013/040557. 
     The methods of preparing host immune cells expressing any of the MHC-CARs described herein may comprise expanding the host immune cells ex vivo. Expanding host immune cells may involve any method that results in an increase in the number of cells expressing MHC-CAR, for example, allowing the host cells to proliferate or stimulating the host cells to proliferate. Methods for stimulating expansion of host cells will depend on the type of host cell used for expression of the chimeric receptors and will be evident to one of skill in the art. In some embodiments, the host immune cells expressing any of the MHC-CAR described herein can be expanded ex vivo prior to administration to a subject. 
     (ii) Additional Genetic Modifications 
     One or more additional genetic modifications can be introduced into host immune cells before, concurrently with, or after the transfection of the MHC-CAR construction. For example, one or more marker and/or suicide genes may be introduced into the host immune cells. Examples include green fluorescent protein (GFP), enhanced blue fluorescent protein (eBFP), and RQR genes, such as RQR8 (a compact marker/suicide gene for T cells which combines target epitopes from CD34 and CD20. Philip et al., Blood 124(8):1277-87; 2014). Such marker/suicide genes may be constructed in one expression cassette with the MHC-CAR components.

     In some instances, the endogenous TCR (alpha chain, beta chain, or both) can be disrupted such that the host immune cells do not express the endogenous TCR. Deficiency in endogenous TCR could avoid undesired T cell activation. Alternative or in addition, certain cell surface receptors can be knocked out. Such surface receptors may be target receptors for disease treatment, for example, CD52, which is a target for MS treatment. Knock-out such target receptors from the MHC-CAR immune cells allows for the co-use of the MHC-CAR immune cells with therapeutic agents specific to the target receptor (e.g., and anti-CD52 antibodies such as alemtuzumab). 
     In some embodiments, the host immune cells may be modified with synthetic surface proteins to enhance their retention in a specific organ or tissue, for example, in the lymph nodes, in tertiary lymphoid organs, or at sites of inflammation. Doing so would allow the modified immune cells to access target pathogenic cells, while minimizing fatal off-target effects due to penetration of the blood brain barrier or free travel of the immune cells through peripheral blood. Cells early in the T cell differentiation pathway (e.g., naïve, stem cell memory, and central memory T cells) travel freely to the lymph nodes. As differentiation progresses, most effector T cells leave the lymph node. Pathologic immune cells can also travel to and accumulate at sites of inflammation. Treatment by activated CAR-T cells has a number of undesirable effects when they react with undesired targets. Interaction with heart tissue can be fatal to cardiac protein, and permeation of the brain can lead to fatal cerebral edema. Recent progress has been made in treatment of the brain cancer gliobastoma using lower doses of CAR T therapy than in systemic treatments for cancer using CD19 CAR T therapy. Brown et al., New England Journal of Medicine, 375(26):2561-2569, 2016. Resolution of inflammation has the potential to transform pathologic to protective environments. Gagliani et al.,  Nature,  523(7559):221-225, 2015. 
     Introducing one or more of lymph node retention proteins into the immune cells can enhance retention of the immune cells in the lymph node, wherein the immune cells still have access to target pathogenic cells, while undesired effects as noted above can be significantly reduced. Naïve lymphocytes enter the lymph node via high endothelial venules (HEVs). Thus, expressing or overexpressing proteins involved in HEV anchoring and/or entry can facilitate the immune cells entering into lymph node. Exemplary lymph node retention proteins include, but are not limited to, CCR7 (a chemokine receptor). MECA79 (a peripheral lymph node addressin), vascular adhesion protein-1 (VAP-1) and CD62 (selectin, a family of the cell adhesion molecules). Azzi et al., Blood 124(4):476-477, 2016; Streeter et al., J. Cell. Biol. 107:1853-186; 1988; Michie et al., Amer, J. Path. 143:1688-1698; 1993; Berg et al., J. Cell. Biol. 114:343-349; 1991; Berg et al., Nature 366:695-698; 1993; and Hemmerich et al., J. Exp. Med. 180:2219-2226; 1994. Alternatively, genes encoding proteins (e.g., sphingosine-1-phosphate receptor-1 or S1P) involved in lymphocyte egress from the thymus and lymph organs can be knocked out from the immune cells. 
     Chemokine receptors and adhesion receptors that promote trafficking to sites of inflammation can also bring MHC-CAR immune cells in contact with pathogenic cells that propagate immune disease [Barreiro et al.,  Cardiovascular research,  86(2):174-182, 2010] see Table 3 and 4. Receptors involved in recruiting immune cells that propagate inflammation include receptors (i.e., CXCR5, CCR7, CCR6) that recruit to tertiary lymphoid organs (where CXCL13, CCL19, CCL20, CCL21 are expressed). 
     One or more genes encoding proteins involved in targeting other organs/tissues, for example, brain/CNS, bone marrow, pancreas, intestine, liver, lungs, spleen, and/or thymus, may also be introduced into or knocked-out from the immune cells. 
     The genes (in Table 3 and 4), by means of virally induced or temporary RNA mediated expression (possibly combined with knockout of the endogenous gene) in the therapeutic cell, may be used to route either Treg or CM cells to the desired location or to treat/remove the desired cells. Barreiro, et al. Cardiovascular research, 86(2):174-182, 2010. If mRNA transfection is utilized then it can allow expression of the chemokine or adhesion receptor for a week. Wang and Rivière. Molecular Therapy-Oncolytics, 3:16015 2016.

     Alternatively or in addition, genes that may enhance immune cell functions, e.g., proliferation, cytotoxicity, etc., can also be introduced into or knocked-out from the immune cells. Examples include TNF/TNFR2 overexpression (for short-lived but more effective CD8 T cells), gld (FasL mutant; for lymphoproliferation; CTLs do not kill via Fas-FasL pathway); lpr (Fas mutant; for upregulation of FasL-target cells resistant to FasL-mediated apoptosis); Granzyme B* deficient (delayed nuclear apoptotic changes in target cells); Granzyme A &amp; B* deficient (delayed nuclear apoptotic changes in target cells); Perforin deficient (complete absence of granule-mediated apoptosis); Perforin and Fast, deficient (defective granule-mediated and Fas-mediated apoptosis); Cathepsin C (dipeptidyl-peptidase 1) deficient (fails to produce active granzymes and some haematopoietic serine proteases); FAS (CD95) underexpression; and/or FASL overexpression.

     In some embodiments, genetic modification that lead to PD blockade can be introduced into the immune cells that express a MHC-CAR as described herein. Such modifications include one or more of PD-1 knockout, PD-L1 or L2 overexpression, or PD-L1 knockout, PD blockade may be combined with an immune-inhibitor (e.g., knockouts of CTLA-4, TIM-3, LAG3, TIGIT, IDO, or Arginase, or CTLA-4Ig secretion), an immunostimulator (e.g., anti-OX40, anti-CD137, IL-2, TLR ligands, or STING), and/or a kinase inhibitor Braf inhibitor or MEK inhibitor) 
     Table 6 below provides exemplary genetic modifications for PD blockade, immune inhibitor, death receptor, immunostimulator, toll like receptor, kinase inhibition, master regulator, cytokine signaling, cell interaction reduction, and drug interaction related edits. The tables also provides target sequences for guide RNA using Cas9 in T cells as well as Genbank accession numbers for sequences that can be used for expression/overexpression. Genome editing using gRNAs is performed through transduction of lentivirus (lentiCRISPRv2) containing the desired gRNA and the  Streptococcus pyogenes  Cas9 nuclease. This can be perform as an alternative to delivery of TALEN RNA in the protocols. Sanjana, et al.  Nature Methods  (2014) 11(8):783-784.

     (iii) Exemplary Genetic Modification Approaches 
     Any conventional genetic modification approaches can be used to genetically modify the immune cells in a manner as described herein. In some embodiments, the genetic modification is performed using genome editing. “Genome editing” refers to a method of modifying the genome, including any protein-coding or non-coding nucleotide sequence, of an organism to knock out the expression of a target gene. In general, genome editing methods involve use of an endonuclease that is capable of cleaving the nucleic acid of the genome, for example at a targeted nucleotide sequence. Repair of the double-stranded breaks in the genome may be repaired introducing mutations and/or exogenous nucleic acid may be inserted into the targeted site. 
     Genome editing methods are generally classified based on the type of endonuclease that is involved in generating double stranded breaks in the target nucleic acid. These methods include use of zinc finger nucleases (ZFN), transcription activator-like effector-based nuclease (TALEN), meganucleases, and CRISPR/Cas systems. 
     In some instances, genetic modification of the immune cells as described herein is performed using the TALEN technology known in the art. TALENs are engineered restriction enzymes that can specifically bind and cleave a desired target DNA molecule. A TALEN typically contains a Transcriptional Activator-Like Effector (TALE) DNA-binding domain fused to a DNA cleavage domain. The DNA binding domain may contain a highly, conserved 33-34 amino acid sequence with a divergent 2 amino acid RVD (repeat variable dipeptide motif) at positions 12 and 13. The RVD motif determines binding specificity to a nucleic acid sequence and can be engineered according to methods known to those of skill in the art to specifically bind a desired DNA sequence (see, e.g., Juillerat, et al. (January 2015). Scientific reports, 5; Miller et al. (February 2011). Nature Biotechnology 29 (2): 143-8; Zhang et. al. (February 2011). Nature Biotechnology 29 (2): 149-53; Geiβler, et al., Boch, (2011), PLoS ONE 6 (5): e19509; Boch (February 2011). Nature Biotechnology 29 (2): 135-6; Boch, et. al. (December 2009). Science 326 (5959): 1509-12; and Moscou et al, (December 2009). Science 326 (5959): 1501. The DNA cleavage domain may be derived from the FokI endonuclease, which is active in many different cell types. The FokI domain functions as a dimer, requiring two constructs with unique DNA binding domains for sites in the target genome with proper orientation and spacing. Both the number of amino acid residues between the TALE DNA binding domain and the FokI cleavage domain and the number of bases between the two individual TALEN binding sites appear to be important parameters for achieving high levels of activity. Miller et al. (2011) Nature Biotech. 29: 143-8. 
     TALENs specific to sequences in a target gene of interest (e.g., TCR, CD52, MHC, and others described herein) can be constructed using any method known in the art, including various schemes using modular components. Zhang et al. (2011) Nature Biotech. 29: 149-53; Geibler et al. (2011) PLoS ONE 6: e19509. 
     A TALEN specific to a target gene of interest can be used inside a cell to produce a double-stranded break (DSB). A mutation can be introduced at the break site if the repair mechanisms improperly repair the break via non-homologous end joining. For example, improper repair may introduce a frame shift mutation. Alternatively, a foreign DNA molecule having a desired sequence can be introduced into the cell along with the TALEN Depending on the sequence of the foreign DNA and chromosomal sequence, this process can be used to correct a defect or introduce a DNA fragment into a target gene of interest, or introduce such a detect into the endogenous gene, thus decreasing expression of the target gene. 
     In some instances, genetic modification of the immune cells as described herin is performed using CRISPR technology as known in the art (CRISPR/Cas systems). Such modification may include the deletion or mutation of a sequence in a target gene of interest can be constructed using a CRISPR-Cas system, where the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas system is an engineered, non-naturally occurring CRISPR-Cas system. The present disclosure utilizes the CRISPR/Cas system that hybridizes with a target sequence in a target gene of interest, where the CRISPR/Cas system comprises a Cas endonuclease and an engineered crRNA/tracrRNA (or single guide RNA (“sgRNA”). In some embodiments, the CRISPR/Cas system includes a crRNA and does not include a tracrRNA sequence. CRISPR/Cas complex can bind to the lineage specific protein polynucleotide and allow the cleavage of the protein polynucleotide, thereby modifying the polynucleotide. 
     The CRISPR/Cas system of the present disclosure may bind to and/or cleave the region of interest within a target gene of interest, within or adjacent to the gene, such as, for example, a leader sequence, trailer sequence or intron, or within a non-transcribed region, either upstream or downstream of the coding region. The guide RNAs (gRNAs) used in the present disclosure may be designed such that the gRNA directs binding of the Cas enzyme-gRNA complexes to a pre-determined cleavage sites (target site) in a genome. The cleavage sites may be chosen so as to release a fragment that contains a region of unknown sequence, or a region containing a SNP, nucleotide insertion, nucleotide deletion, rearrangement, etc. Cleavage of a gene region may comprise cleaving one or two strands at the location of the target sequence by the Cas enzyme. In one embodiment, such, cleavage can result in decreased transcription of a target gene. In another embodiment, the cleavage can further comprise repairing the cleaved target polynucleotide by homologous recombination with an exogenous template polynucleotide, wherein the repair results in an insertion, deletion, or substitution of one or more nucleotides of the target polynucleotide. 
     The terms “gRNA,” “guide RNA” and “CRISPR guide sequence” may be used interchangeably throughout and refer to a nucleic acid comprising a sequence that determines the specificity of a Cas DNA binding protein of a CRISPR/Cas system. A gRNA hybridizes to (complementary to, partially or completely) a target nucleic acid sequence in the genome of a host cell. The gRNA or portion thereof that hybridizes to the target nucleic acid may be between 15-25 nucleotides, 18-22 nucleotides, or 19-21 nucleotides in length. In some embodiments, the gRNA sequence that hybridizes to the target nucleic acid is 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleotides in length. In some embodiments, the gRNA sequence that hybridizes to the target nucleic acid is between 10-30, or between 15-25, nucleotides in length. 
     In addition to a sequence that binds to a target nucleic acid, in some embodiments, the gRNA also comprises a scaffold sequence. Expression of a gRNA encoding both a sequence complementary to a target nucleic acid and scaffold sequence has the dual function of both binding (hybridizing) to the target nucleic acid and recruiting the endonuclease to the target nucleic acid, which may result in site-specific CRISPR activity. In some embodiments, such a chimeric gRNA may be referred to as a single guide RNA (sgRNA). 
     As used herein, a “scaffold sequence,” also referred to as a tracrRNA, refers to a nucleic acid sequence that recruits a Cas endonuclease to a target nucleic acid bound (hybridized) to a complementary gRNA sequence. Any scaffold sequence that comprises at least one stem loop structure and recruits an endonuclease may be used in the genetic elements and vectors described herein. Exemplary scaffold sequences will be evident to one of skill in the art and can be found, for example, in Jinek, et al.  Science  (2012) 337(6096):816-821, Ran, et al.  Nature Protocols  (2013) 8:2281-2308, PCT Application No. WO2014/093694, and PCT Application No. WO2013/176772. In some embodiments, the CRISPR-Cas system does not include a tracrRNA sequence. 
     In some embodiments, the gRNA sequence does not comprise a scaffold sequence and a scaffold sequence is expressed as a separate transcript. In such embodiments, the gRNA sequence further comprises an additional sequence that is complementary to a portion of the scaffold sequence and functions to bind (hybridize) the scaffold sequence and recruit the endonuclease to the target nucleic acid. 
     In some embodiments, the gRNA sequence is at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or at least 100% complementary to a target nucleic acid (see also U.S. Pat. No. 8,697,359, which is incorporated by reference for its teaching of complementarity of a gRNA sequence with a target polynucleotide sequence). It has been demonstrated that mismatches between a CRISPR guide sequence and the target nucleic acid near the 3′ end of the target nucleic acid may abolish nuclease cleavage activity (Upadhyay, et al. Genes Genome Genetics (2013) 3(12):2233-2238). In some embodiments, the gRNA sequence is at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or at least 100% complementary to the 3′ end of the target nucleic acid (e.g., the last 5, 6, 7, 8, 9, or 10 nucleotides of the 3′ end of the target nucleic acid). 
     Example sgRNA sequences, including both modified and unmodified sgRNAs, targeting the T cell receptor alpha constant (TRAC) gene are provided herein. As will be evident to one of ordinary skill in the art, selection of sgRNA sequences may depend on factors such as the number of predicted on-target and/or off-target binding sites. In some embodiments, the sgRNA sequence is selected to maximize potential on-target and minimize potential off-target sites. 
     In some embodiments, the Cas endonuclease is a Cas9 nuclease (or variant thereof) or a Cpf1 nuclease (or variant thereof). Cas9 endonucleases cleave double stranded DNA of a target nucleic acid resulting in blunt ends, whereas cleavage with Cpf1 nucleases results in staggered ends of the nucleic acid. 
     In general, the target nucleic acid is flanked on the 3′ side or 5′ side by a protospacer adjacent motif (PAM) that may interact with the endonuclease and be further involved in targeting the endonuclease activity to the target nucleic acid. It is generally thought that the PAM sequence flanking the target nucleic acid depends on the endonuclease and the source from which the endonuclease is derived. For example, for Cas9 endonucleases that are derived from  Streptococcus pyogenes , the PAM sequence is NGG, although the PAM sequences NAG and NGA may be recognized with lower efficiency. For Cas9 endonucleases derived from  Staphylococcus aureus , the PAM sequence is NNGRRT. For Cas9 endonucleases that are derived from  Neisseria meningitidis , the PAM sequence is NNNNGATT. Cas9 endonucleases derived from  Streptococcus thermophilus , St1Cas9 an dSt3Cas9, the PAM sequences are NNAGAAW and NGGNG, respectively. For Cas9 endonuclease derived from  Treponema denticola , the PAM sequence is NAAAAC. In some embodiments, the Cas endonuclease is a Cpf1 nuclease. In contrast to Cas9 endonucleases, Cpf1 endonuclease generally do not require a tracrRNA sequence and recognize a PAM sequence located at the 5′ end of the target nucleic acid. For a Cpf1 nuclease, the PAM sequence is TTTN, in some embodiments, the Cas endonuclease is MAD7 (also referred to as Cpf1 nuclease from Eubacterium rectale) and the PAM sequence is YTTTN. 
     In some embodiments, genetically engineering a cell also comprises introducing a Cas endonuclease, or nucleic acid sequence encoding such (e.g., mRNA encoding a Cas endonuclease), into the cell. In some embodiments, the Cas endonuclease and the nucleic acid encoding the gRNA are provided on the same nucleic acid (e.g., a vector). In some embodiments, the Cas endonuclease and the nucleic acid encoding the gRNA are provided on different nucleic acids (e.g., different vectors). In some embodiments, the Cas endonuclease is provided as an mRNA encoding the Cas endonuclease and the gRNA is provided as a modified gRNA molecule. Alternatively or in addition, the Cas endonuclease may be provided or introduced into the cell in protein form. 
     In some embodiments, the Cas endonuclease is a Cas9 enzyme or variant thereof. In some embodiments, the Cas9 endonuclease is derived from  Streptococcus pyogenes, Staphylococcus aureus, Neisseria meningitidis, Streptococcus thermophilus , or  Treponema denticola . In some embodiments, the nucleotide sequence encoding the Cas endonuclease may be codon optimized for expression in a host cell. In some embodiments, the endonuclease is a Cas9 homolog or ortholog. 
     In some embodiments, the nucleotide sequence encoding the Cas9 endonuclease is further modified to alter the activity of the protein. In some embodiments, the Cas9 endonuclease has been modified to inactivate one or more catalytic resides of the endonuclease. In some embodiments, the Cas9 endonuclease has been modified to inactivate one of the catalytic residues of the endonuclease, referred to as a “nickase” or “Cas9n”, Cas9 nickase endonucleases cleave one DNA strand of the target nucleic acid. In some embodiments, the methods described herein involve two distinct cleavage reactions, in which one Cas9 nickase is directed to cleave one DNA strand of the target nucleic acid and a Cas9 nickase is directed to cleave the second DNA strand of the target nucleic acid. 
     (iv) MHC-CAR Regulatory T Cells (Treg) 
     Any of the MHC-CAR-expressing T cells disclosed herein can be regulatory T cells (Treg), which may mimic the immune modulation activity of follicular regulatory cells. As used herein, regulatory T cells or Treg cells, which are also known as suppressor T cells, refer to a subpopulation of T cells that modulate the immune system, maintain tolerance to self-antigens, and/or prevent autoimmune disease. Treg cells function as immunesuppressors to suppress or downregulate induction and/or proliferation of effector T cells, such as pathologic CD4+ and/or CD8+ cells involved in autoimmune diseases. 
     The genetically modified Treg cells disclosed herein express one or more of the biomarkers associated with Treg cells in nature, for example, CD4, FOXP3, CD25, CD45R e.g., CD45RA or CD45RO), or a combination thereof. The Treg cells may be prepared using (derived from) peripheral blood mononuclear cells (PBMCs) isolated from a suitable donor (e.g., the human patient subject to the treatment). Methods for isolating the subpopulation of Treg cells from PBMCs are well known in the art, for example, cell sorting. Expression vectors for a suitable MHC-CAR construct, as well as other genetic modification (e.g., those described herein) can be introduced into the Treg subpopulation via methods as described herein, or other methods known in the art. Alternatively, the genetically modified. Treg cells may be prepared by introducing a transgene coding for CD25 and/or other Treg cell markers into suitable T cells, which can be further modified to introduce the expression cassette for the MHC-CAR and optionally other genetic modification as described herein. 
     In some embodiments, the genetically modified Treg cells may be further modified to display (e.g., surface express or surface attach) molecules targeting a specific type of pathologic cells (e.g., CD4+ cells or CD8+ cells) and/or display molecules targeting a specific tissue site lymph node or an inflammation site). 
     In some examples, the genetically modified Treg cells further express a chimeric receptor (CAR) comprising an extracellular domain such as a single-chain antibody (scFv) specific to a B cell surface marker, for example, CD19. Alternatively or in addition, the Treg cells may further express a chimeric receptor comprising an extracellular domain (e.g., scFv) specific to a T cell surface marker, for example, CS-1. Such a chimeric receptor can be a cell-surface receptor comprising an extracellular domain, a transmembrane domain, and a cytoplasmic domain (e.g., comprising a co-stimulatory domain, a cytoplasmic signaling domain such as CD3ζ, or a combination thereof) in a combination that is not naturally found together on a single protein. 
     The Treg cell may further display a molecule targeting lymph nodes and/or germinal center, for example, CXCR5, and/or display a molecule targeting an inflammation site, for example, CCR6. Targeting germinal center B cells (GC B cells) may be mediated, at least in part, by a specialized helper T cell subset, the CXCR5highPD-1high T follicular helper (TFH) cells. Foxp3+ Treg can be diverted to become TFH repressors pia expression of Bcl6 and SAP-mediated interaction with B cells. The resulting follicular regulatory T cells (TFR) are expected to share features of both TFH and Treg cells, localize to germinal centers, and regulate the size of the TFH cell population and germinal centers in vivo. 
     Further, the Treg cells disclosed herein may include one or more of the additional genetic modification as described herein, for example, checkpoint molecule knock out. 
     The Treg cells expressing B-cell or T-cell specific CAR may target pathologic B cells and/or T cells involved in an autoimmune disease. For example, the genetically modified Treg cells as described herein would be expected to exhibit functions similar to follicular regulatory cells, e.g., targeting B cells, T cells, and/or dendritic cells, thereby, e.g., downregulating B cell stimulation, secreting suppressive cytokines that can inhibit activation of germinal center (GCB cells (such as Il-10 and TGF-Beta), inducing cytolysis of Tfh (through MHC CAR) and GC) B (e.g., through the CD19 CAR), and/or mechanical disrupting signaling transduction to GC B cells or to T follicular helper (Tfh) cells (e.g., through binding to GC B and MHC-peptide Tfh). Alternatively or in addition, the Treg cells may potentially engage both helper T cells, B cells, and/or antigen presenting cells, or in some instances, physically blocking the engagement. 
     III. Application of Immune Cells Expressing MHC-CAR in Immunotherapy 
     Host immune cells expressing MHC-CAR (the encoding nucleic acids or vectors comprising such) described herein are useful for targeting and eliminating pathogenic cells involved in autoimmune diseases, such as MS, type 1 diabetes, lupus, rheumatoid arthritis, etc. In some embodiments, the subject is a mammal, such as a human, monkey, mouse, rabbit, or domestic mammal. In some embodiments, the subject is a human, for example, a human patient having, suspected of having, or at risk for an autoimmune disease (e.g., MS). 
     The MHC-CAR-expressing immune cells can be mixed with a pharmaceutically acceptable carrier to form a pharmaceutical composition, which is also within the scope of the present disclosure. To perform the methods described herein, an effective amount of the immune cells expressing any of the MHC-CAR constructs described herein can be administered into a subject in need of the treatment. The immune cells may be autologous to the subject, i.e., the immune cells are obtained from the subject in need of the treatment, genetically engineered for expression of the MHC-CAR constructs and optionally contains one or more of the additional genetic modifications as described herein, and then administered to the same subject. Administration of autologous cells to a subject may result in reduced rejection of the immune cells as compared to administration of non-autologous cells. Alternatively, the immune cells are allogeneic cells, i.e., the cells are obtained from a first subject, genetically engineered for expression of the MHC-CAR construct, and administered to a second subject that is different from the first subject but of the same species. For example, allogeneic immune cells may be derived from a human donor and administered to a human recipient who is different from the donor. 
     In some embodiments, the immune cells are co-used with a therapeutic agent for the target immune disease, for example, Alemtuzumah for treating MS. Such immunotherapy is used to treat, alleviate, or reduce the symptoms of the target immune disease for which the immunotherapy is considered useful in a subject. 
     The efficacy of the MHC-CAR immunotherapy may be assessed by any method known in the art and would be evident to a skilled medical professional. For example, the efficacy of the immunotherapy may be assessed by survival of the subject and/or reduction of disease symptoms in the subject. 
     In some embodiments, the immune cells expressing any of the MHC-CAR disclosed herein are administered to a subject who has been treated or is being treated with a therapeutic agent for an autoimmune disease. The immune cells expressing any one of the MHC-CAR disclosed herein may be co-administered with the therapeutic agent. For example, the immune cells may be administered to a human subject simultaneously with the therapeutic agent. Alternatively, the immune cells may be administered to a human subject during the course of a treatment involving the therapeutic agent. In some examples, the immune cells and the therapeutic agent can be administered to a human subject at least 4 hours apart, e.g., at least 12 hours apart, at least 1 day apart, at least 3 days apart, at least one week apart, at least two weeks apart, or at least one month apart. 
     To practice the method disclosed herein, an effective amount of the immune cells expressing MHC-CAR or compositions thereof can be administered to a subject (e.g., a human MS patient) in need of the treatment via a suitable route, such as intravenous administration. Any of the immune cells expressing MHC-CAR or compositions thereof may be administered to a subject in an effective amount. As used herein, an effective amount refers to the amount of the respective agent the immune cells expressing MHC-CAR or compositions thereof) that upon administration confers a therapeutic effect on the subject. Determination of whether an amount of the cells or compositions described herein achieved the therapeutic effect would be evident to one of skill in the art. Effective amounts vary, as recognized by those skilled in the art, depending on the particular condition being treated, the severity of the condition, the individual patient parameters including age, physical condition, size, gender and weight, the duration of the treatment, the nature of concurrent therapy (if any), the specific route of administration and like factors within the knowledge and expertise of the health practitioner. In some embodiments, the effective amount alleviates, relieves, ameliorates, improves, reduces the symptoms, or delays the progression of any disease or disorder in the subject. In some embodiments, the subject is a human. In some embodiments, the subject is a human cancer patient. 
     In some embodiments, the subject is a human patient suffering from an autoimmune disease, which is characterized by abnormal immune responses attacking a normal body part. Examples of autoimmune diseases include multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, juvenile idiopathic arthritis (also known as juvenile idiopathic arthritis), Sjögren&#39;s syndrome, systemic sclerosis, ankylosing spondylitis, Type 1 diabetes, autoimmune thyroid diseases (Grave&#39;s and Hashimoto&#39;s), multiple sclerosis myasthenia gravis, inflammatory bowel disease (Crohn&#39;s or ulcerative colitis), Psoriasis, or a diseases mentioned in Table 1. 
     There are numerous stages in the immune cascade where, in general, an autoimmune disease can be impacted. There is a continuum of interventions made possible by the combination of edits that the methods disclosed herein comprises. For example, Treg cells displaying a distinct set of surface molecules, in addition to the MHC-CAR, can be used for treating the autoimmune disease at different stages. 
     In the early stage of many immune disorders, including MS, there exist unexplained deficits in regulatory mechanisms and/or tolerance induction exists in MS and there begin repeated attacks on the nervous system by T cells. Treg cells expressing a suitable MHC-CAR and anti-CD19 CAR (optionally with other genetic modifications as described herein) may be used for intervention. 
     An advantage of autoreactive Treg cells is their ability to act as “bystander” suppressors, to dampen inflammation at a site-specific manner in response to cognate antigen expressed locally by affected tissues. The induction of regulatory T cells (by autoantigens) can suppress disease progression even when there are a variety of autoantigens (or when the initiating/primary) autoantigen is unknown. Tregs can travel relatively freely, and inhibit T cells and B cells and prevent return to an inflammatory environment. These autoreactive Tregs are advantageous in their ability to act as bystander suppressors and dampen inflammation in a site-specific manner in response to cognate antigen expressed locally by affected tissues. 
     Thus, the genetically modified Treg cells may be designed to mimic the suppressor function of the autoreactive Treg cells. Such Treg cells may be modified, for example, to have PD-L1/PD-1 knocked out, to display CCR6 and/or scFv targeting MOG to route to the site of inflammation, to express a suitable MHC-CAR and/or anti-CD19-CAR. Alternatively, the Treg cells may be modified, for example, to have PD-L1/PD-1 knocked out, to display CXCR5 to route to germinal centers and/or ectopic lymph nodes, to express a suitable MHC-CAR and/or anti-CD19-CAR. These types of Treg cells may interact with pathogenic cells at the site of inflammation, block pathogenic interactions, and/or calm inflammatory environment. They can be used at an early disease stage (to inhibit pathogenicity) or after cytotoxic therapy (to prevent return to an inflammatory environment). 
     Relapsing-remitting MS (mid-stage) naturally regulates itself, and treatments which augment these natural regulatory mechanisms will help control the disease process. In successful disease treatment, there is a shift from Th1 cells to Th2 and Th3 cells, and the appearance of other regulatory cells. At this stage, therapeutic targets will include both pathogenic B and pathogenic T cells. Treg cells for treating such mid-stage disease may express a suitable MHC-CAR as described herein, and an additional CAR targeting B cells (e.g., an anti-CD19 CAR) or targeting T cells such as CD8+ cells. The Treg cells may further display CXCR5 or free of CXCR5 targeting. Treg cells expressing anti-CD19 CAR may be used to eliminate B cells in the germinal center. 
     When MS changes from relapsing remitting to the chronic progressive form (late-stage), T cells enter a state of chronic activation and degenerative processes occur. Aggressive treatment against cytotoxic CD8+ cells requires a CAR augmentation that is sufficiently cytotoxic. At this point, a treatment may shift from one primarily driven by Treg cells to one driven by MHC-CAR CD8+ T cells and even MHC-CAR CS-1 cells. The ultimate goal remains the same: to suppress pathology through cytotoxicity enhanced by bystander effect. Genetically engineered T cells for use at this disease stage may express a suitable MHC-CAR, and an additional CAR targeting pathologic T cells involved in the late stage of the disease, for example, CD5+ cells. In some examples, the additional CAR may target CS-1 (also known as SLAMF7), which is a glycoprotein expressed on CD8+ T cells. CS1 is a promising antigen that can be used to target and kill CD8+ T cells and plasma cells. CS1-CAR T cells secrete more IFN-gamma as well as IL-2, expressing higher levels of activation marker CD69, higher capacity for degranulation, and display enhanced cytotoxicity. Anti-CS1 CAR will target CD8+ T-cells. The genetically modified T cells may further display a molecule for bone-marrow targeting of plasma cells, such as CXCR4, and their targeting to inflamed tissues, with CXCR3.

     EXAMPLES 
     The instant examples focuses on the development of a cellular immunotherapy utilizing chimeric receptors to selectively redirect therapeutic T cells against myelin basic protein (MBP)-specific T lymphocytes implicated in MS [16]. The results of this program can support the further development of redirected therapeutic T cells able to counteract pathologic, self-specific T lymphocytes, and specifically validate humanized MBP-DR2-chimeric receptors as a therapeutic target in MS [29]. 
     Example 1: Construction of Modified T-Cells Specific to Myelin Basic Protein 
     A construct for an antigen-specific T-cell receptor (TCR) that targets a MBP-loaded major histocompatibility complex-chimeric antigen receptor (MHC-CAR) is designed for reintroduction into cells with TCR knockouts for assays. Design of the TCR constructs is based on an antigen-specific TCR with a published structure and TCR expression constructs validated in human cell lines [17, 46, 51, 52], Green fluorescent protein (eGFP) or luciferase is genetically encoded for labeling [28]. Exemplary lentiviral expression vectors comprising the TCR construct and reporting gene are provided in  FIG. 1 . 
     Several cell lines are selected for testing TCR expression and activity, including Jurkat E6-1 (a control strain that expresses TCR), Jurkat J.RT3-T3.5 (a strain that lacks TCRb), SupT1 (a strain with damaged TCRa), and primary human T cells (which contain a diverse population of TCR clonotypes). 
     Jurkat E6-1 cells are an established human T lymphocyte cell line from peripheral blood. It is used as a control cell line expressing TCR [15, 18]. 
     Jurkat RT3-T3.5 lacks TCRβ due to a mutation that precludes expression of the TCR β-chain. It also fails to express surface CD3 or produce the T-cell receptor α,β heterodimer. It is therefore used for validating T-cell receptor gene transfer [1, 6, 21, 49]. 
     SupT1 is a human lymphoblast line expressing multiple lineage markers and is used because it encodes a non-functional receptor and fails to express TCRα [49]. 
     PMBC-derived primary human T cells contain a diverse repertoire of TCR clonotypes. 
     Lentiviral vectors containing the antigen-specific TCR as illustrated in  FIG. 1  are used to transduce cancer cell lines lacking at least one TCR chain, and are subsequently assessed for expression using fluorescence-activated cell sorting (FACs). In cancer cell lines containing the antigen-specific TCR, luciferase is added to the cell line following successful stable expression to enable its use in mouse studies. 
     TCR constructs for mRNA, multicistronic mRNA, and lentiviral transduction proceed straightforwardly, via a screen based on the genetically encoded eGFP and labeling with anti-TCR or anti-CD3 antibody [3, 19]. 
     Example 2: Construction of MHC-Based Chimeric Receptors (MHC-CAR) and T-Cells Expressing Such 
     
         
         
           
             (i) Design MHC-CAR Constructs 
           
         
       
    
     Receptors for adoptive cell therapy that genetically link the MBP 84-102 epitope to human leukocyte antigen HLADR2 are generated and, either incorporate or lack chimeric intracellular signaling domains [29]. The antigen-major histocompatibility complex (Ag-MHC) domain serves as receptor, binding the TCR of MBP-specific target cells. The Ag-MHC-CAR has been validated in preclinical mouse models with CD3-ζ (i.e. a first-generation signaling domain), which may optionally be in combination with additional co-stimulatory signaling domains (i.e. second- or third-generation signaling domains) for efficacy in humans, following the methodology provided in [9, 25]. A schematic illustration of the various designs of MHC-CAR is provided in  FIG. 2 . 
     MHC-CARs are designed based on the structure of HLA-DR, and combined with a variety of internal cytoplasmic costimulatory domains. The MHC-CAR has two subunits: (i) an α-chain that contains the leader sequence, DRA*1010 domain, and a cytoplasmic domain; and (ii) a β-chain that contains a leader sequence (from HLA-DRB1*1501), a peptide (DENPVVHFFKNIVTRPP (SEQ ID NO: 15) from myelin basic protein), a domain (from HLA-DRB1*1501), and a cytoplasmic signal domain, for example, CD3z [29].  FIG. 3 . The DNA used to create mRNA contains either single chains (shown as one embodiment in  FIG. 4 ) or are multicistronic and separated by orthogonal 2A sequences as illustrated in  FIG. 5 . Genetically encoded eBFP or RQR8 are introduced into the cells for cell-labeling or to provide a mechanism for depletion [4, 5, 37, 40].  FIGS. 3 and 5 . 
     As illustrated in  FIG. 6 , the designed MHC-CAR has a number of sites for tagging. Site 1 is an HLA-DR antibody binding site for cases where native HLA-DR is either not expressed due to CIITA editing [26, 38]. Sites 2 and 3 are potential insertion sites for polyhistidine-tag motifs [24]. Sites 4 and 5 represent RQR and RQR8, respectively [37]. Multiple sclerosis is shown to affect blood brain barrier permeability, so in order to enhance the safety of therapeutic MHC-CAR, genetically encoded RQR would allow for rapid depletion of MHC-CAR T cells upon administration of rituximab, a chimeric monoclonal antibody treatment used offlabel in the treatment of severe MS [42]. 
     (ii) Construction of T Cell Lines Expressing MHC-CAR 
     A number of cell lines discussed below are selected for testing the MHC-CAR construct. Assays are then continued in human T cells in order to establish clinically translatable protocols. 
     K56 cells lack Class I and Class II MHC, allowing for tagless verification of HLA-DR expression using antibodies (HLA-DR is a component of the MHC-CAR) [45]. Expression assays will allow assessment of the MHC-CAR expression relative to RQR8 expression using flow cytometry, and the same lentiviral construct is then used in PMBC-derived T cells [23]. 
     KM-H2 is a human Hodgkin&#39;s lymphoma line that can be used as an HLA-DR positive control line [34, 44]. Jurkat E6-1, as noted above, conditionally express HLA-DR upon delivery of CIITA and can be used to evaluate CIITA TALEN if CIITA knockout is used [33]. 
     In addition, primary human T cells can be used. PMBC-derived primary human T cells are purified and enriched from Whole blood, and then activated. Transduction follows enrichment. The cells are incubated with recombinant human interleukin-2 (and/or IL-7 and/or IL-15) [7, 12, 43]. Based on preclinical studies and the anticipated therapeutic course, the desired cell type is CD5+ T cells with the molecular and functional features of stem cell memory TSCM, central memory TCM, and naive cells TN [11, 22, 32, 35]. Antibody staining allows for cell immunotyping [27]. 
     Initial constructs, including a permutation of signaling domains (CD3z, 41BB, CD28) are expressed using mRNA, multicistronic mRNA, and lentiviral strategies in K562 cells. The cell line&#39;s lack of MHC Class I and II allow the tagless verification of MHC-CAR expression using the HLA-DR antibodies, following a successfully employed strategy [29]. Quantification of the expression efficiency in more clinically relevant cell lines, including therapeutic T cells, depends on construct, and will be measured using genetically encoded fluorescent reporters (BFP) or antibody staining of the RQR site, a polyhistidine-(HIS)-tag, or the MHCCAR (with an HLA-DR antibody if CIITA is inactivated using TALEN). Labeling sites are indicated in  FIG. 6 . To test rates of MHC-CAR delivery as a potential therapeutic vector, BFP is removed from constructs while RQR is retained to provide for depletion control. Expression rates of the clinically relevant construct are measured using antibody staining post-editing. 
     The transcription activator-like effector technology (TALEN) can also be used for preparing T cells expressing MHC-CAR. Human T cell lines are activated, transfected with TALEN, and either transfected or transduced with MHC-CAR. They are then stained and analyzed by flow cytometry to assess TALEN gene inactivation and MHC-CAR expression. Upon verification of construct expression in desired cell lines, TALEN transduction (TCRa and CD52 or CIITA as discussed below) into human T cell lines is performed. TALEN is introduced into activated human T cell lines, and the MHC-CAR is subsequently introduced into the same T cell lines for evaluation. The modification of the human T cells can be performed in this order to prevent incidental fratricidal killing of MEW modified cells due to the native TCR [10]. The activity of TALEN-edited MHC-CAR T-cells is to be confirmed. 
     (iii) Modification of MHC-CAR-Expressing T Cells Via Transcription Activator-Like Effectors (TALENs) 
     Human T cells are selected to confirm inactivation of TCRa, and CD52 or CIITA genes by TALEN, followed by evaluation in combination with MHC-CAR, using TALENs. Transcription activator-like effectors (TALENs) bind DNA in a sequence-specific manner. The DNA binding domain contains a highly conserved 33-34 amino acid sequence with a divergent 2 amino acid RVD (repeat variable dipeptide motif) conferring specific nucleotide recognition [23, 31]. 
     Mutation of either α or β chain of the TCR is sufficient for disruption of surface TCR expression [15, 36]. TALEN is used to inhibit expression of two genes in the therapeutic cell without introducing a proliferative advantage through undesired translocations [39][ 47 ]. TCR expression is inhibited through a TRAC-targeted TALEN to prevent graft versus host disease (GvHD) and allow for the creation of an allogeneic therapy [15, 39, 47]. 
     CD52 deletion can be made for alemtuzumab compatibility. Alemtuzumab is a humanized anti-CD52 IgG-1 monoclonal antibody that targets and depletes circulating T and B lymphocytes [41]. Alemtuzumab can be used as rescue therapy or as first line drug in severe-onset MS [50], and will be co-administered in the human patient population. TALEN knockout will make MHC-CAR compatible with concurrent treatment in patients [14, 39], Further. CIITA deletion can be made for characterization of HLA-DR in MHC-CAR CIITA is a protein coding gene essential for the transcriptional activity of HLA Class II promoter [26]. Knockout would allow for the direct measurement of HLA-DR using antibodies for characterization of MHC-CAR expression [38, 53]. The inhibition of CD52 expression allows for concurrent treatment with Lemtrada R (alemtuzumab), an FDA-approved treatment for multiple sclerosis [42]. Alemtuzumab is also used as a lympho-depleting/lympho-suppressive agent that aids in the engraftment of CAR T therapies [39]. A CAR T-cell therapy modified with TRAC- and CD52-targeted TALENs is currently being tested in clinical trials [38, 40, 43]. 
     TALEN to inactivate MHC Class II transactivator (CIITA) in place of CD52, as inactivation of CIITA is expected to inhibit HLA-DR expression [26][38], thus allowing for the direct identification of MHC-CAR-containing cells by HLA-DR antibody staining. Validated TALENs (TRAC: TTGTCCCACAGATATCCagaaccctgaccctgCCGTGTACCAGCTGAGA (SEQ ID NO: 376), CD52:TTCCTCCTACTCACCATcagcctcctgttatGGTACAGGTAAGAGCAA (SEQ ID NO: 371), CIITA: TTCCCTCCCAGGCAGCTCacagtgtgccaccaTGGAGTTGGGGCCCCTA (SEQ ID NO: 366)) are obtained from Cellectis or designed to target previously validated sites [38, 43]. 
     Human T cells are activated and electroporated with mRNA encoding variants of 3 different TALEN: TCR-alpha constant chain, CD52, and CIITA. Cells are surface stained with anti-CD3 or anti-TCR (TCR-alpha constant chain), anti-CD52 (CD52), or anti-HLA-DR (CIITA), and then analyzed by flow cytometry. 
     In the TALEN expression assays, the ability of previously validated TALENs to inactive target genes are re-validated [39]. Translocation studies and off-target studies are reperformed, and several whole-genome sequences confirm results. GUIDE-seq can be used as an alternative to whole genome sequencing to confirm on- and off-target editing [8]. 
     One of more of the following endogenous genes are to be edited to reduce interaction with other cells: TCR (through TCR alpha or beta chain; to reduce targeting to undesired cells), CIITA (regulates expression of MHC Class II genes; target cells for taster deletion), B7-1(CD80) and/or B7-2(CD86) knockout, and b2m (regulates expression of MHC Class I genes) with NKG2D ligands or UL18. 
     Further, one or more of the following genes can be edited to modify the function of an interacting PD-L1+/−CTLA4-Ig overexpression; PD-L1/2 overexpression+/−PD-1 knockout; FasL overexpression+/−Fas knockout; Galectin 9 overexpression+/−TIM3 knockout; and/or PVT/CD155 overexpression+/−TIGIT knockout. Defects in PD-1, Fas, TIm3, TIGIT predispose patients to autoimmunity. Some drugs can restore function (for example: Tim3, glatiramer acetate and IFN-beta). If autologous cells from a patient suffering autoimmune disease are utilized they may require patient specific correction of defective genes that influence CM and Treg function. Their personal mutation set may also determine whether CTL or Treg cells will be the most therapeutically relevant, and whether some cellular modification will be effective, if either autologous or allogeneic cells are used. 
     Further, the following edits may modify the location and/or function of the cells (for example, to make it more like a follicular regulatory cell): 
     MHC-CAR-(FOX3P)-(CS1 or CD19 CAR)/(CS-1 knockout required for CS-1 CAR) 
     MHC-CAR-(FOX3P)-(CCR7 or CXCR5) 
     Moreover, the following edits can enable combination therapies for autoimmune diseases (e.g., MS specific therapeutics)
         RQR tag: engineered T cells can be removed with rituximab (kill switch). A tag for the newly approved anti-CD20 antibody Ocrevus could be generated.   Rapamycin switch: CARs only in/active when patient is treated with rapamycin (tacrolimus)   CD52 knockout: allows pretreatment with Lemtrada (alemtuzumab) to decrease number of immune cells present   VLA-4 knockout: can treat with tysabri to move pathogenic immune cells to periphery but engineered cells are forced to stay there (may not be ideal for patients with established MS as cells that are stuck in the brain spinal cord; however, simultaneous mRNA expression of VLA-4 can provide temporary access to those locations)   IL-6 antibody (Toclizumab) secretion from engineered T cell: helpful when the engineered T cell must access the brain and spinal cord, but this drug cannot access the locations due to the BBB       

     Example 3: Investigation of MHC-CAR Activities 
     (i) Preparation of Primary T Cells Expressing MHC-CAR 
     Primary T cells can be prepared as follows. T cells are isolated from peripheral blood mononuclear cells (EasySep Human T Cell Enrichment Kit, Stemcell Technologies) and activated (Dynabeads Human T-Activator CD3/CD28, Life Technologies) with (X-Vivo 15 medium, Lonza; 20 mg/ml. Il-2, Miltenyi; 5% human AB serum, Seralab). A suitable MHC-CAR construct containing a MBP antigenic peptide is introduced into the primary T cells using a conventional method. Surface expression of the MHC-CAR construct is verified by FACS and antibody staining. 
     (ii) MHC-CAR Activity Tests In Vitro 
     Upon verification of construct trafficking and expression (with mRNA, multicistronic mRNA, Lentivirus), activity tests are conducted in vitro. All tests are conducted at different effector:target (E:F) cell concentrations. The in vitro tests provide an initial evaluation of MHC-CAR signaling domains and T cell subsets. 
     (iii) Signaling Domain Assessment by IL-2 Production 24 hours post electroporation, human T cells transiently engineered with MHC-CAR are stimulated with plate-bound HLA-DR antibody, to determine whether MHC-CAR (containing various signaling domains) is functional. Il-2 production is measured 24 hours later using a StemCell IL-2 ELISA kit. This test provides a quick assay as to whether variants should be reengineered or abandoned [29]. 
     (iv) Interaction MHC-CAR Cells and Pathogenic TCR Cells Through Proliferation Assay 
     Target cell lines transiently expressing TCR are magnetically sorted for TCR expression 24 hours after electroporation and irradiated, in order to test whether engagement of the MHC-CAR with antigen-specific TCR stimulates proliferation of MHC-CAR containing T cells. Alternatively, target cell lines that stably express TCR are irradiated. The irradiated cells displaying (+/−antigen-specific) TCR are incubated with CFSE-labeled MHCCAR cells and proliferation is measured after culture at different T:E ratios [30]. 
     (v) Degranulation Assay 
     CAR T-cells are labeled through epitopes on RQR (which are not being expressed on the target cells used) or eBFP instead of T cell markers. The assay is performed for cell lines with transient or stable expression (the example of transient expression is described). 24 hours post-electroporation, MHC-CAR human T-cells with either RQR8 or BFP are co-cultured with target (antigen-specific TCR SupT1 or Jurkat) or control (+/−TCR Jurkat or TCR-SupT1) cells for 6 hours. Transiently expressed (and later stably expressing) target cells are electroporated with antigen-specific TCR and sorted with CD3 magnetic beads post-electroporation. The RQR+ or BFP+ MHC-CAR T-cells (as identified with anti-rituximab antibody, QBEnd10 antibody) are analyzed by flow cytometry to detect the expression of the degranulation marker CD107a on their surface [2]. 
     (vi) Cytokine Secretion Assay 
     The assay is performed for cell lines with transient or stable expression (transient expression is described). The human T cells transiently expressing the MHC-CARs are assessed for cytokine secretion following co-culture with target cells 24 hours post electroporation. Human T cells transiently expressing the MHC-CARs are co-cultured with target (antigen-specific TCR containing Jurkat or SupT1 cells) or control (+/−non-antigen-specific Jurkat or SupT1) cells for 24 hours. The antigen-specific TCR is then killed by irradiation before the assay. The supernatants are harvested and analyzed using the TH1/TH2 cytokine cytometric bead array kit to quantify the cytokines produced by T cells [13]. In MHC-CAR T-cells produce IFN and other cytokines in co-culture with antigen-specific TCR expressing target cells but not in co-culture with control cells. 
     (vii) IFNγ Release Assay 
     Various levels of MHC-CAR expressing cells are incubated with irradiated TCR T-cells 24 hours after transfection. Co-cultures are maintained for 24 hours. After incubation and centrifugation, supernatants are tested with IFNγ detection by ELISA. 
     (viii) Cytotoxicity Assay 
     TCR T-cells are incubated with therapeutic MHC-CAR as well as control cells. Target and control cells are labeled with fluorescent intracellular dyes (CFSE or Cell Trace Violet) before co-culturing with MHC-CAR T-cells. The co-cultures are incubated for 4 hours. After this incubation period, cells are labeled with a fixable viability dye and analyzed by flow cytometry. Viability of each cell population (target or negative control) is determined and the percentage of specific cell lysis is calculated. Cytotoxicity assays are carried out 48 hours after transduction. 
     (ix) Inhibition Assay 
     PBMCs are co-cultured with irradiated or mitomycin-treated engineered cells expressing the MHC-CAR construct. As control, PBMCs are co-cultured with irradiated or mitomycin-treated engineered T cells that do not express the MHC-CAR construct. 7 days later, cell proliferation from a human patient donor A is measured by XTT colorimetric assay or by CFSE dilution (FACS analysis). Although cell proliferation would be observed in control, no or limited cell proliferation is expected when engineered T cells express secreted FP. The results from this experiment aim to show that alloreactive T cells proliferation is inhibited when the MHC-CAR expressing T cells express FP. 
     (x) Proliferation 
     To test whether engagement of the MHC-CAR with antigen-specific TCR stimulates proliferation of MHC-CAR containing T cells, target cell lines transiently expressing TCR are magnetically sorted for TCR expression 24 hours after electroporation and irradiated. Alternatively, target cell lines that stably express TCR are irradiated. The irradiated cells displaying (+/−antigen-specific) TCR are incubated with CFSE-labeled MHC-CAR cells and proliferation is measured after culture at different T:E ratios. 
     (xi) In Vivo Tests 
     MHC-CAR (with mouse and human MHC) in mouse T cells has previously shown therapeutic efficacy in experimental allergic encephalomyelitis, the mouse model for multiple sclerosis [25, 29], Here we test whether MHC-CAR in human cells can target human TCR in human T cell lines, using an in vivo mouse model analogous to that in prior CAR preclinical studies [39]. The in vivo tests allow further evaluation of MHC-CAR signaling domains and T cell subsets. 
     The in vivo activity of MHC-CAR T-cells can be verified in a mouse xenograft model as illustrated in  FIG. 7 . 
     Immunodefficient NOG mice are intravenously injected with antigen-specific TCR-luciferase expressing T-cells as an MS xenograft mouse model. Mice then receive intravenous doses of MHC-CAR T-cells tested at different doses, either 2 or 7 days post-injection with tumor cell line. Intravenous injection with T-cells that are not transduced with the CAR lentiviral vector serve as control. Bioluminescent signals are determined at the day of T-cell injection (DO), at D7, 14, 21, 28 and 40 after ‘T’-cell injection in order to follow the expansion of TCR-luciferase expressing cells in different animals [39]. 
     CAR T-cells with similar background modifications (TALEN to inactivate native TCR and minimize graft vs host, TALEN to inactivate CD52 and allow simultaneous treatment with alemtuzumab, and RQR8 to allow depletion) to the ones shown here have been previously validated in mouse models and are now used in a UCART19 clinical trial [39]. 
     (xii) Kill-Switch Verification 
     Transduced T cells are exposed to 25% baby-rabbit complement (AbD Serotec) for 4 hours with or without inclusion of pharmaceutical complements (rituximab, tysabri, or alemtuzumab) to examine complement-dependent cytotoxicity (CDC)-mediated sensitivity. Miltenyi CD34 magnetic bead-selected-transduced RQR8 T-cells are compared against a similarly treated population of Q8-transduced T cells to demonstrate specificity of CDC-mediated deletion. Further examination of CDC assay parameters was achieved through time-course/dose-titration assays using RQR8-transduced T cells incubated with pharmaceutical complement at 12.5, 25, 50, and 100 mg/mL and time-point assessments ranging between 1 to 120 minutes. 
     Example 4: Regulatory T Cells (Treg) Expressing MHC-CAR 
     Therapies that antigen specifically target pathologic T lymphocytes responsible for multiple sclerosis and other autoimmune diseases are expected to have improved therapeutic indices compared with antigen-nonspecific therapies. This example provides an exemplary cellular immunotherapy that uses chimeric antigen receptors to selectively redirect therapeutic T cells against myelin basic protein-specific T lymphocytes implicated in MS 
     Treg Cell Sorting, Transduction, and Expansion 
     CD4+ T cells are isolated from PMBC via RosetteSep (STEMCELL Technologies) and enriched for CD25+ cells (Miltenyi Biotec) prior to sorting into live CD4+CD45RO−CD45RA+CD25+ Tregs and CD4+CD45RO−CD45RA+CD25− control T cells by FACS. Sorted T cells are stimulated with artificial APCs (aAPCs) loaded with aCD3 niAbs in 1,000 U/ml or 100 U/ml of IL-2, for Tregs or non-reg control T, respectively. One day later, cells are transduced with lentivirus. At day 7, ΔNGFR+ cells were purified with magnetic selection (Miltenyi Biotec), then re-stimulated with aAPCs as above and expanded for 6 to 7 days. 
     Flow Cytometry: 
     For phenotypic analysis, cells were stained with fixable viability dye (FVD) (65-0865-14 and 65-0866-14, eBioscience) and for surface markers before fix/perm with FOXP3/Transcription Factor Staining Buffer Set (eBioscience), followed by staining for intracellular proteins. For analysis of cytokine production, cells were stimulated with 10 ng ml PMA and 500 ng/ml ionomycin, in the presence of brefeldin A (10 μg/ml) (all Sigma-Aldrich) for 4 hours. Samples were analyzed by flow cytometry. 
     Microscopy: 
     PBMCs are labeled with PKH26 or PKH67 (Sigma-Aldrich, PKH26GL-1KT and PKH67GL-1KT), and Tregs are labeled with cell proliferation dye (CPD) eFluor450 (eBiosciences, 65-0842-85) and then suspended in a 3D gel of 1.5% rat tail collagen type I (Ibidi) composed of 1×DMEM and 10% FCS per the manufacturer&#39;s general 3D gel protocol. The cell suspension is pipetted into μ-Slide Chemotaxis3D and allowed to polymerize for 30 minutes in a humidified incubator at 35° C. and 5% CO2 (Tokai Hit) on a Leica TCS SP8 confocal microscope. The outer chambers are filled with 1×DMEM and images recorded using a ×10/0.30 objective every 2 minutes for 3 hours. eFluor450, and PKH26 were excited at 405 nm, 488 nm, and 561 nm, and the fluorescence emission is collected at 415-470 nm, 495-525 nm, and 570-650 nm, respectively. The number of interactions between CAR-Tregs and either target or control cells is quantified every 20 minutes. Cells that do not move were excluded from the analysis. The total numbers of each labeled cell type per field of view can be counted using the analyze particles function in ImageJ (imagej.nih.gov/ij/). 
     Treg-Specific Demethylated Region (TSDR) Analysis 
     Treg stable expression of stable Foxp3 is associated with selective demethylation of TSDR within the Foxp3 locus. In order to test for stable expression, DNA from frozen T cell pellets is was isolated with the DNeasy Blood and Tissue Kit (QIAGEN) and bisulfite converted with the EZ Direct Kit (Zymo Research). PCR of BisDNA was performed with the Human FOXP3 Kit (Epigen DX) and prepared for pyrosequencing using PyroMark buffers (QIAGEN), then assayed on a Biotage PyroMark Q96 MD pyrosequencer (QIAGEN). Results were calculated with Pyro Q-CpG software (Biotage). 
     Cytokine Production 
     To measure cytokine production, T cell lines are stimulated with K562 cells (1 K562:2 T cells) for 48 hours. Supernatants are collected and cytokine concentration was determined by the Human Th1/Th2/Th17 Cytokine Kit (BD Biosciences) and analyzed. 
     Suppression of MHC CAR-Specific Proliferation 
     To test whether Treg specific for target were also capable of suppressing CD4+ T cell proliferation, MHC CAR-specific CD4+ T clones are isolated. An Epstein Barr Virus-tranformed B lymphablastoid cell line was transduced with MHC-CAR using lentivirus. EBV cell lines were were grown overnight, irradiated at 150 Gy, and cocultured with CPD-labeled MHC CAR-specific CD4+ T clones in the absence or presence of CAR-expressing Tregs or conventional T cells. Proliferation is determined after 4 days, and percentage of suppression of MHC CAR-specific clones calculated using percentage of proliferation as follows: (100−[(% proliferated MHC CAR+test)/(% proliferated MHC CAR alone)]×100). 
     Upon verification of construct trafficking and expression (with mRNA, multicisttronic mRNA, and/or lentivirus), activity tests will begin in vitro. All tests are conducted at different effector:target (E:F) cell concentrations. The in vitro tests are expected to provide an initial evaluation of MHC-CAR signaling domains and T cell subsets. 
     Transient or Lentiviral Expression of Chemokine and Adhesion Receptors in T Cells 
     Receptors are expressed in human T cells after electroporation of mono/polycistronic mRNA or lentiviral transduction. Expression of the receptor is analyzed using flow cytometry. In summary: 5×10 6  T cells preactivated several days (3-5) with anti CD3/CD28 coated beads and IL2 were re-suspended in cytoporation buffer T, and electroporated with 45 μg of mRNA. Twenty-four hours after electroporation, human T cells engineered using polycistronic mRNAs encoding the multi-chain CARs were labeled with a fixable viability dye eFluor-780 and a PE-conjugated goat anti mouse IgG F(ab′)2 fragment specific, and analyzed by flow cytometry. Alternately the receptors were vectorized in lentivirus, expressed, and analyzed similarly. 
     In Vitro Chemotaxis Assay 
     Transduced T cells were used in chemotaxis assays as previously described [Bürkle et al.,  Blood,  110(9):3316-3325, 2007; Wu and Hwang,  Journal of immunology,  168(10):5096, 2002.; Singh et al., Journal of immunology, 180(1): 214-221, 2008.; Ryu et al., Molecules and  Cells,  39.12:898-908, 2016.]. Cells (˜20,000 cells in medium, one million cells, 5×10 6 /mL) were placed on top of the 5-μm pore size filters in duplicate, whereas medium with and without chemokines were placed into the lower chamber. After 30 min, 1 h, 3 h, 5 hr, 24 hr at 37° C., migrated cells that had fallen to the bottom of the plate were: 
     A. photographed using a 4× objective. Three random views from each of two wells were counted using Image Pro Plus (Media Cybernetics, Silver Spring, Md.). Three independent experiments were performed with similar results. 
     B. 400 μL of the cell suspension was added to 100 μL of a solution containing 4×10−7 M FITC-labeled phalloidin, 0.5 mg/mL 1-alpha-lysophosphatidylcholine (both from Sigma, St Louis, Mo.), and 7% formaldehyde in phosphate-buffered saline (PBS). The fixed cells were analyzed by flow cytometry on a FACSCalibur, and all time points are plotted relative to the mean relative fluorescence of the sample before addition of the chemokine. 
     C. the cells in the lower chamber were counted using Countess II FL (Thermo Fisher Scientific. USA) or the O.D. value at 450 nm was measured using a Versamax microplate reader (Molecular Devices). 
     Example 5: Expression of MHC-Based Chimeric Receptors (MHC-CAR) Ins HEK293 Cells 
     Constructs encoding MHC-CARs were constructed as discussed in Example 2 and assessed for expression in HEK293 cells. Briefly, Construct 1 includes an EF1alpha short promoter, CD19 CAR (4G7-CAR), CCR6, and GFP (provided by SEQ ID NO: 426); and Construct 2 includes a EF1alpha short promoter, RQR8, MHC-CAR1 part B MHC-CAR1 part A, and GFP (provided by SEQ ID NO: 409). 
     Constructs 1, 2, or media control (non-transfected) was transfected into HEK293 cells and cultured. The cells were assessed for expression by microscopy based on GFP expression. Populations of GF-positive cells were observed in the groups that were transfected with Construct 1 or Construct 2. The cells were also assessed for expression of the components encoded by the constructs by flow cytometry. Tables 8 and 9. 
     Construct 1 Expression 
     For detection of CCR6, cells were incubated with an anti-CCR6 monoclonal antibody conjugated to APC (17-1969-42, eBioscience); and for detection of CD19, cells were incubated with a biotinylated CD19 (Acro CD9-H8259, Acro Biosystems) followed by a streptavidin-PE (405203, BioLegend®).

     Example 6: Expression of CD3 
     Expression of CD3 was assessed to determine the efficacy of CRISPR methods targeting the T cell receptor alpha constant (TRAC) gene. Briefly, sgRNAs targeting the TRAC gene were generated by amplifying the target site using forward primer 5′-AGCGCTCTCGTACAGAGTTGG-3′ (SEQ ID NO: 385)) and reverse primer (5′-AAAAAAAGCACCGACTCGGTGCC-3′ (SEQ ID NO: 386). 
     The unmodified sgRNA is provided by the nucleic acid sequence:

     Primary human stimulated CD3+ T-cells were transfected with an mRNA encoding Cas9 (Cas9 only) or both an snRNA encoding Cas9 and sgRNAs targeting the TRAC gene. After 7 days post-transfection, expression of CD3 was assessed by flow cytometry. The cells were incubated with a 1:100 dilution of an anti-CD3-APC antibody (clone OKT3; BioLegend® cat. no. 317318). As shown in  FIG. 11 , transfection of an mRNA encoding Cas9 and sgRNAs targeting the TRAC gene resulted in a substantial reduction in CD3 expression. 
     Example 7: Kill Switch Verification 
     Efficacy of the RQR8 kill switch encoded in example Construct 2 was assessed using a cell viability assay. Briefly, HEK cells were transfected with media only, Construct 1 (SEQ ID NO: X), Construct 2 (which encodes the rituximab-mediated RQR8 kill switch, SEQ ID NO: X), or both Construct 1 and Construct 2. The transfected HEK293 cells were harvested, counted, and resuspended at 1×10{circumflex over ( )}6 cells/mL. 300 uL of the cellular suspension was transferred into each of 4 wells of a 48-well tissue culture plate. 100 uL of complete medium and 4 uL of Rituximab were added to the second well, and 100 uL of freshly prepared baby rabbit complement and 4 uL of Rituximab were added to the fourth well. The plates were incubated for 2, 4, or 24 hours. The assay was terminated by the adding 1 uL of chilled Annexin buffer (150 mMNaCl, 10 mM/HEPES, 10 mM CaCl), and then the sample was transferred into a pre-prepared flow cytometry tube containing 3 ml, of Annexin V buffer. 
     Samples were harvested by centrifugation and any residual buffer was blotted with paper towels. The samples were then stained with 1 uL of Annexin V APC, vortexed, and placed in subdued lighting for 15 minutes. The samples were then washed with Annexin V buffer and supplemented with 5 uL of propridium iodide/mL buffer and placed on ice pending flow cytometry performed immediately following final suspension. 
     The percentage of GFP-positive cells was quantified to quantify the killing induced by the RQR8 kill switch. As shown in  FIG. 12 , incubation with complement alone resulted in some cell death, however this reduction in viability was observed in all of the groups of cells. Cell death was observed in cells that expressed Construct 2 or both Constructs 1 and 2 the presence of the combination of rituximab and complement, indicating specific RQR8-mediated cell death.
