App. No. 63/234090 filed August 17, 2021 entitled “ANTI-EGFR CHIMERIC ANTIGEN RECEPTORS”; and U.S. Prov. App. No. 63/122839 filed December 8, 2020 entitled “CODON-OPTIMIZED EGFR806CAR THERAPEUTIC SEQUENCE,” which are each expressly incorporated by reference herein in its entirety. REFERENCE TO SEQUENCE LISTING [0002] The present application is being filed along with a Sequence Listing in electronic format.

FIELD OF THE INVENTION [0003] Aspects of the present disclosure generally relate to anti-EGFR chimeric antigen receptors (CAR), and T cells containing such CARs. Some embodiments pertain to the enhanced expression of anti-EGFR CARs, processes for expressing anti-EGFR CARs, and methods of using the enhanced expression to target cancers such as glioblastoma, liquid tumors, or solid tumors. BACKGROUND OF THE INVENTION [0004] Many therapies have been utilized for the treatment of cancer. Today, popular therapies include surgery, chemotherapy, radiation therapy, hormone therapy, targeted drug therapy, and cellular therapy. The cellular therapy for patients suffering from cancer or disease is the injection of cellular material, such as living cells, into a patient in need. This can include the infusion of polyclonal or antigen specific T-cells, activated killer cells, natural killer cells, dendritic cells, or macrophages. Recent advancements have been made in the development of chimeric antigen receptor (CAR) bearing T-cells, a promising therapeutic route for cancer immunotherapy and viral therapy. [0005] CAR T-cell therapy is an immunotherapy, wherein T-cells are isolated in a laboratory and genetically manipulated to express a synthetic receptor, which recognizes a particular antigen or protein displayed on a cell, such as a cancer cell, and then the cells are reinfused into a patient. Clinical trials have shown promising evidence of anti-tumor activity; however, CAR T-cell therapy still suffers from the insufficient activation of cells, short half- lives, and inefficient targeting to cancer tissue. Accordingly, additional approaches to CAR T cell therapy are direly needed.

By manipulating the nucleic acid template, peptide, polypeptide, and protein mutations such as substitutions, deletions, truncations, additions, duplications, or fusions of more than one peptide, polypeptide, or protein can be performed. These fusions of more than one peptide, polypeptide, or protein can be joined in the same molecule adjacently, or with extra amino acids in between, e.g. linkers, repeats, epitopes, or tags, or any other sequence that is, is about, is at least, is at least about, is not more than, or is not more than about, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 150, 200, or 300 bases long, or any length in a range defined by any two of the aforementioned lengths. The term “downstream” on a polypeptide as used herein has its plain and ordinary meaning as understood in light of the specification and refers to a sequence being after the C-terminus of a previous sequence. The term “upstream” on a polypeptide as used herein has its plain and ordinary meaning as understood in light of the specification and refers to a sequence being before the N-terminus of a subsequent sequence. Proteins may contain amino acids other than the 20 gene encoded amino acids. Proteins include those modified by natural processes (e.g. processing and other post-translational modifications) and by chemical modification techniques. The same type of modification may be present in the same or varying degree at several sites in a given protein and a protein may contain many modifications. Modifications may occur in the peptide backbone, the amino acid side-chains, and the amino or carboxyl termini. Examples of modifications include acetylation; acylation; ADP-ribosylation; amidation; covalent attachment of flavin, a heme moiety, a nucleotide or nucleotide derivative, a lipid or lipid derivative, a carbohydrate, or phosphotidylinositol; cross-linking; cyclization; disulfide bond formation; demethylation, formation of covalent cross-links; glycosylation; hydroxylation; iodination; methylation; myristoylation; oxidation; proteoytic processing; phosphorylation; S-nitrosation; racemization; lipid attachment; sulfation, gamma- carboxylation of glutamic acid residues; or hydroxylation. [0068] As used herein, the term “codon optimized” has its usual meaning as understood by those skilled in the art and refers to the optimization of a sequence for gene expression or protein production using molecular biology methods. For example, modifying a less-common codon with a more common codon may affect the half-life of the mRNA or alter its structure by introducing a secondary structure that interferes with translation of the message. In some embodiments, codon can be optimized using computer software and algorithms that predict the optimal sequences for expression efficiency. Nucleic acids can also be optimized for expression based on the cell type it will be incorporated in. Suitable host cells can include, as non-limiting examples, prokaryotic cells such as E. coli, P. aeruginosa, B. subtilus, or V. natriegens, or eukaryotic cells such as S. cerevisiae, plant cells, insect cells, nematode cells, amphibian cells, fish cells, or mammalian cells, including human cells, such as but not limited to T cells. AU or a portion of a gene can be optimized. In some embodiments, the desired modulation of expression is achieved by optimizing essentially the entire gene. In other embodiments, the desired modulation will be achieved by optimizing part but not all of the gene. [0069] As used herein, the term “promoter” has its usual meaning as understood by those skilled in the art and refers to a sequence of DNA to which proteins bind that regulates transcription of a polynucleotide. Examples of a promoter include, but are not limited to, EF1a, HTLV1, EF1a/HTLV (SEQ ID NO: 2), CMV, CAG, PGK, TRE, U6, UAS, T7, Sp6, lac, araBad, trp, or Ptac. Typically,a promoter is located in he 5' region of a polynucleotide to be transcribed. More typically, promoters are defined as the region upstream of the first exon. A promoter can be any length. For example, short promoters, such as the EF1a core promoter, are between 100-300 base pairs in length, while long promoters, such as EF1a/HTLV, are between 400-1000 base pairs in length. In some embodiments, the promoter is naturally occurring. In other embodiments, the promoter is chemically synthesized according to techniques in common use. See, for example, Beaucage et al. (1981) Tet. Lett. 22:1859 and U.S. Pat. No.4,668,777. A promoter can either regulate constitutive transcription, in which the gene product is continuously expressed, or inducible transcription, in which the expression of a gene product is influenced by certain conditions such as light, temperature, chemical concentration, protein concentration, conditions in an organism, cell, or organelle, etc. Promoters can be eukaryotic or prokaryotic, and modified to enhance the rate of expression or total copy number of its corresponding gene product. The promoter may also include at least one control element such as an upstream element. Such elements include UARs and optionally, other DNA sequences that affect transcription of a polynucleotide such as a synthetic upstream element. The term “promoter control element” as used herein describes elements that influence the activity of the promoter. Promoter control elements include transcriptional regulatory sequence determinants such as, but not limited to, enhancers, scaffold/matrix attachment regions, TATA boxes, transcription start locus control regions, UARs, URRs, other transcription factor binding sites and inverted repeats. [0070] As used herein, the term “regulatory sequence” has its usual meaning as understood by those skilled in the art and refers to any nucleotide sequence that influences transcription or translation initiation and rate, or stability and/or mobility of a transcript or polypeptide product. Regulatory sequences include, but are not limited to, promoters, promoter control elements, protein binding sequences, 5' and 3' UTRs, transcriptional start sites, termination sequences, polyadenylation sequences, introns, certain sequences within amino acid coding sequences such as secretory signals, protease cleavage sites, etc. [0071] As used herein, the term “operably linked” has its usual meaning as understood by those skilled in the art and denotes a physical or functional linkage between two or more elements, e.g., polypeptide sequences or polynucleotide sequences, which permits them to operate in their intended fashion. For example, an operably linkage between a polynucleotide of interest and a regulatory sequence (for example, a promoter) is functional link that allows for expression of the polynucleotide of interest. In this sense, the term “operably linked” refers to the positioning of a regulatory region and a coding sequence to be transcribed so that the regulatory region is effective for regulating transcription or translation of the coding sequence of interest. In some embodiments disclosed herein, the term “operably linked” denotes a configuration in which a regulatory sequence is placed at an appropriate position relative to a sequence that encodes a polypeptide or functional RNA such that the control sequence directs or regulates the expression or cellular localization of the mRNA encoding the polypeptide, the polypeptide, and/or the functional RNA. Thus, a promoter is in operable linkage with a nucleic acid sequence if it can mediate transcription of the nucleic acid sequence. Operably linked elements may be contiguous or non-contiguous. In addition, in the context of a polypeptide, “operably linked” refers to a physical linkage (e.g., directly or indirectly linked) between amino acid sequences (e.g., different segments, regions, or domains) to provide for a described activity of the polypeptide. In the present disclosure, various segments, regions, or domains of the chimeric polypeptides of the disclosure may be operably linked to retain proper folding, processing, targeting, expression, binding, and other functional properties of the chimeric polypeptides in the cell. Unless stated otherwise, various regions, domains, and segments of the chimeric polypeptides of the disclosure are operably linked to each other. Operably linked regions, domains, and segments of the chimeric polypeptides of the disclosure may be contiguous or non-contiguous (e.g., linked to one another through a linker). DNA operably linked to a promoter is under transcriptional initiation regulation of the promoter or in functional combination therewith. [0072] As used herein, the terms “self-cleavage peptide” or “self-cleaving peptide” have their usual meaning as understood by those skilled in the art and refer to a peptide sequence that undergoes cleavage of a peptide bond between two constituent amino acids, resulting in separation of the two proteins that flank the sequence. The cleavage is believed to be a result of a ribosomal “skipping” of the peptide bond formation between the C-terminal proline and glycine in the 2A peptide sequence. Polycistronic mRNA regulating elements were discovered with the investigation of viruses. The internal ribosome entry site (IRES) element was reported by two independent labs in 1988 studying poliovirus and encephalomyocarditis virus. [0073] The term “internal ribosome entry site (IRES)” as used herein has its plain and ordinary meaning as understood in light of the specification and refers to the element that recruits the 40S subunit to promote translation of downstream mRNA. Similarly, the 2A family of self-cleaving peptides - P2A (SEQ ID NO: 3), E2A, F2A and T2A (SEQ ID NO: 4) were discovered in porcine teschovirus-1, equine rhinitis A, foot-and-mouth disease, and thosea asigna viruses, respectively. Both 2A and IRES elements allow multiple peptides to arise from a single strand of mRNA. [0074] As used herein, the terms “selection marker” or “selectable marker” have their usual meaning as understood by those skilled in the art and refer to a gene which encodes a polypeptide that provides a phenotype to the cell containing the gene such that the phenotype allows either positive or negative, selection or screening of cells containing the selection marker gene. The selection marker gene may be used to distinguish between transformed and non-transformed cells or may be used to identify cells having undergone recombination or other kinds of genetic modifications. In some embodiments, the selection marker is co- expressed with the codon-optimized sequence corresponding to EGFR806CAR construct (SEQ ID NO: 1). Under this condition, the presence of a marker allows for the selection of cells containing the codon-optimized sequence. Non-limiting examples of selection markers include DHFRdm (SEQ ID NO: 5), DHFR, HER2T, MDR1, MRP1, O6-MGMT, cytidine deaminase, glutathione transferase Yc, or aldehyde dehydrogenase. [0075] As used herein, the term “intracellular signaling domain” has its usual meaning as understood by those skilled in the art and refers to a portion of a protein facing the cellular interior which, when activated, positively or negatively regulates one or more signaling pathways in the host cell. Non-limiting examples of signaling pathways include proliferation, cytokine release, survival, cytotoxicity, phagocytosis, and metabolism. In some embodiments, the signaling domain includes a primary signaling domain. In some embodiments, the signaling domain includes a primary signaling domain and a secondary signaling domain. In some embodiments, the protein with said intracellular signaling domain is a transmembrane receptor, such as but not limited to EFGR, the EGFR variant EGFR806CAR construct, or the codon optimized EGFR variant EGFR806CAR construct. Non-limiting examples of an intracellular signaling domain include 41BB, CD3ζ, OX40, CD27, or CD28. In some embodiments, the sequence contains two intracellular signaling domains, such as but not limited to 41BB and CD3ζ (SEQ ID NO: 7). [0076] As used herein, the term “transmembrane domain” has its usual meaning as understood by those skilled in the art and refers to a portion of a protein that, when included, gets incorporated into the membrane region of a cell or organelle. In some embodiments, the membrane is the plasma membrane of a cell. Thus, a “transmembrane” protein is a protein containing the transmembrane domain. Most transmembrane domains form alpha helices. The transmembrane domain of a protein will span the entirety of the membrane. Proteins may contain multiple transmembrane domains, each of which will independently span the membrane. Other domains of a protein are referred to as either “extracellular” or “intracellular”, depending on their location relative to the cytoplasm and cell exterior. Non- limiting examples of transmembrane domains include CD28tm (SEQ ID NO: 8), &'^Įtm, CD4tm, &'^ζtm, or the T cell receptor (TCR)-associated ζ chain. [0077] As used herein, the terms “hinge” or “spacer” are used equivalently and have their usual meaning as understood by those skilled in the art and refer to a domain whose length, position and structure provide flexibility to the protein. In certain cases, the spacing of the antigen-recognition domain can be modified to reduce activation-induced cell death. The hinge region is found in IgG, IgA, and IgD immunoglobulin classes, such as but not limited to IgG4 (SEQ ID NO: 9). Cells, T cells, and CAR-T cells [0078] The terms “individual”, “subject”, or “patient” as used herein have their usual meaning as understood by those skilled in the art and thus includes a human or a non- human mammal. The term “mammal” is used in its usual biological sense. Thus, it specifically includes, but is not limited to, primates, including simians (chimpanzees, apes, monkeys) and humans, cattle, horses, sheep, goats, swine, rabbits, dogs, cats, rodents, rats, mice, guinea or pigs. [0079] The term “cell” as used herein has its plain and ordinary meaning as understood in light of the specification and can refer to any cell type. In some embodiments, said cells are mammalian cells. In some embodiments, said cells are human cells. [0080] The term “immune cell” as used herein has its plain and ordinary meaning as understood in light of the specification and refers to any cell that participates in either the adaptive or innate immune response. Immune cells develop from stem cells in the bone marrow and become different types of white blood cells. Non-limiting examples of immune cells include memory cells, precursor T cells, precursor B cells, hematopoietic stem cells, myeloid progenitors, lymphoid progenitors, T cells, T helper cells, thymocytes, regulatory T cells, effector T cells, cytotoxic T lymphocytes, gamma/delta T cells, B cells, plasma cell, natural killer cells, antigen presenting cells, dendritic cells, macrophages, histiocytes, astrocytes, myeloid cells, monocytes, and granulocytes such as basophils, eosinophils, neutrophils, or mast cells. [0081] The term “T cell” is used in its usual biological sense. Thus, a T cell is lymphocyte that participates in the adaptive immune system and contains a T-cell receptor on the cell surface. Non-limiting examples of a T cell include a CD4+ T cell, a CD8+ T cell, a CD8+ cytotoxic T cell, a naïve CD8+ T cell, a CD8+ memory T cell, a central memory CD8+ T cell, a regulatory CD8+ T cell, an IPS derived CD8+ T cell, an effector memory CD8+ T cell, a bulk CD8+ T cell, a CD4+ T helper cell, a naïve CD4+ T cell, a CD4+ memory T cell, a central memory CD4+ T cell, a regulatory CD4+ T cell, an IPS derived CD4+ T cell, an effector memory CD4+ T cell, or a bulk CD4+ T cell. [0082] The term “B cell” is used in its usual biological sense. Thus, a B cell is a lymphocyte that participates in the adaptive immune system and secretes antibodies. B cells can produce many types of antibodies and surface markers, such as but not limited to CD19, CD20, CDld, CD5, CD19, CD20, CD21, CD22, CD23/Fc epsilon RII, CD24, CD25/IL-2 R alphaCD27/TNFRSF7, CD32, CD34, CD35, CD38, CD40 (TNFRSF5), CD44, CD45, CD45.1, CD45.2, CD54 (ICAM-1), CD69, CD72, CD79, CD80, CD84/SLAMF5, LFA-1, CALLA, BCMA, B-cell receptor (BCR), IgMs, IgD, B220/CD45R, Clq R1/CD93, CD84/SLAMF5, BAFF R TNFRSF13C, B220/CD45R, B7-1/CD80, B7-2/CD86, TNFSF7,TNFRSF5, ENPP-1, HVEM/TNFRSF14, BLIMP1/PRDM1, CXCR4, DEP- 1/CD148, or EMMPRIN/ CD147. [0083] The term "antibody," as used herein, refers to an immunoglobulin molecule which is able to specifically bind to a specific epitope on an antigen. Antibodies can be intact immunoglobulins derived from natural sources or from recombinant sources and can be immunoreactive portions of intact immunoglobulins. The antibodies useful in the present invention may exist in a variety of forms including, for example, polyclonal antibodies, monoclonal antibodies, humanized monoclonal antibodies, intracellular antibodies ("intrabodies"), Fv, Fab and F(ab)2, as well as single chain antibodies (scFv), camelid antibodies or humanized antibodies (Harlow et al., 1999, Using Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, NY; Harlow et al., 1989, Antibodies: A Laboratory Manual, Cold Spring Harbor, New York; Houston et al., 1988, Proc. Natl. Acad. Sci. USA 85:5879-5883; Bird et al., 1988, Science 242:423-426). [0084] The term “antigen” as used herein has its plain and ordinary meaning as understood in light of the specification and refers to a compound, composition, or substance that can stimulate the production of antibodies or a T-cell response in an animal, including compositions that are injected or absorbed into an animal. An antigen reacts with the products of specific humoral or cellular immunity, including those induced by heterologous immunogens. The term “antigen” includes all related antigenic epitopes. Non-limiting examplesof antigensincludeEGFR,EGFRvIII,HER2,MSLN,PSMA,CEA,GD2,IL13Rα2 , GPC3, CAIX, L1-CAM, CA125, CD133, FAP, CTAG1B, MUC1, or FR-α [0085] The term “T-cell receptor” (or “TCR”) as used herein has its plain and ordinary meaning as understood in light of the specification and refers to a transmembrane protein found on the surface of T cells that is capable of recognizing an antigen. TCRs are described using the International Immunogenetics (IMGT) TCR nomenclature, and links to the IMGT public database of TCR sequences. Native T-cell receptors consist of two polypeptide chains, most commonly either alpha and beta chains, or gamma and delta chains. Broadly, each chain comprises variable, joining and constant regions. Each variable region comprises three CDRs (Complementarity Determining Regions) embedded in a framework sequence, one being the hypervariable region named CDR3. The joining regions of the TCR are similarly defined by the unique IMGT TRAJ and TRBJ nomenclature, and the constant regions by the IMGT TRAC and TRBC nomenclature. The unique sequences defined by the IMGT nomenclature are widely known and accessible to those working in the TCR field. For example, they can be found in the IMGT public database. The "T cell Receptor Factsbook", (2001) LeFranc and LeFranc, Academic Press, ISBN 0-12-441352-8 also discloses sequences defined by the IMGT nomenclature, but because of its publication date and consequent time- lag, the information therein sometimes needs to be confirmed by reference to the IMGT database. [0086] The terms “chimeric antigen receptors” (or “CAR”) T cells have their plain and ordinary meaning as understood in light of the specification and refer to T cells that have been genetically engineered to produce an artificial T-cell receptor for use in immunotherapy. Non-limiting examples of an artificial T-cell receptor include EGFR806CAR construct, or codon-optimized EGFR806CAR construct. A chimeric antigen receptor recognizes cell- surface tumor-associated antigen independent of human leukocyte antigen and employs one or more signaling molecules to activate genetically modified T cells for killing, proliferation, and cytokine production (Jena et al., 2010). The term “chimeric antigen receptors (CARs),” as used herein, may refer to artificial T-cell receptors, chimeric T-cell receptors, or chimeric immunoreceptors, for example, and encompass engineered receptors that graft an artificial specificity onto a particular immune effector cell. Adoptive transfer of T cells expressing CAR has shown promise in multiple clinical trials. It is now possible to use a modular approach to manufacture clinical grade genetically modified T cells. In specific embodiments, CARs direct specificity of the cell to a tumor associated antigen, for example. Non-limiting examples of tumor associated antigens include EGFR, EGFRvIII, HER2, MSLN, PSMA, CEA, GD2, IL12Rα2,GPC3,CAIX,L1-CAM, CA125, CD133, FAP, CTAG1B, MUC1, or FR-α .In some embodiments, CARs comprise an intracellular activation domain, a transmembrane domain, and an extracellular domain comprising a tumor associated antigen binding region. In certain cases, CARs comprise domains for additional co-stimulatory signaling, such as CD3-zeta, FcR, CD27, CD28, CD137, DAP10, and/or OX40. In some cases, molecules can be co-expressed with the CAR, including co-stimulatory molecules, reporter genes for imaging (e.g., for positron emission tomography), gene products that conditionally ablate the T cells upon addition of a pro-drug, homing receptors, chemokines, chemokine receptors, cytokines, and cytokine receptors. [0087] CAR T cells can also express a truncated version of the epidermal growth factor receptor (EGFRt) on the T cell surface (SEQ ID NO: 6). It has been shown that targeting EGFRt with the IgG1 monoclonal antibody cetuximab eliminates CD19 CAR T cells both early and late after adoptive transfer in mice, resulting in complete and permanent recovery of normal functional B cells, without tumor relapse. EGFRt can be incorporated into many clinical applications to regulate the survival of gene-engineered cells. See, for example, Paszkiewicz et al. (2016) J Clin Invest 126(11): 4262-4272. Cancer and consequent targeting by CAR-T therapy [0088] Further disclosed herein is a method of administering the novel polynucleotides and/or cells expressing the polynucleotides as a therapy against cancer.

Actual dosage levels of active ingredients in an active composition of the presently disclosed subject matter can be varied so as to administer an amount of the active composition or compound that is effective to achieve the desired response for a particular subject and/or application. The selected dosage level will depend upon a variety of factors including, but not limited to, the activity of the composition, formulation, route of administration, combination with other drugs or treatments, severity of the condition being treated, and the physical condition and prior medical history of the subject being treated. In some embodiments, a minimal dose is administered, and dose is escalated in the absence of dose-limiting toxicity to a minimally effective amount. Determination and adjustment of an effective dose, as well as evaluation of when and how to make such adjustments, are contemplated herein. [0092] As used herein, the term “pharmaceutically acceptable” has its usual meaning as understood by those skilled in the art and refers to carriers, diluents, excipients, and/or stabilizers that are nontoxic to the cell or mammal being exposed thereto at the dosages and concentrations employed or that have an acceptable level of toxicity.

[0109] As disclosed herein, the inventors discovered that integrating a human codon-optimized EGFR806CAR construct sequence into T cells dramatically enhanced expression and conferred a therapeutic benefit for cancer therapies. Specific examples of these findings are described in the examples below. EXAMPLES Example —Design of a human codon optimized EGFR806CAR construct and insertion into T cells [0110] As disclosed herein, the inventors designed three novel sequences of EGFR806CAR construct to test for expression in T cells and effectiveness in cancer therapy. These constructs included the EGFR806CAR construct controlled by a short EF1a promoter (253 nucleotides) (FIG. 1A), also known herein as the “HIV7.2 construct”; as well as the EGFR806CAR construct controlled by a long EF1a and HTLV promoter (544 nucleotides) (FIG.1B), also known herein as the “HIV7.3 construct”. The third construct was controlled by the long EF1a and HTLV promoter, and the entire open reading frame was codon optimized for expression in humans (FIG. 1C) (SEQ ID NO: 10), also known herein as the “coHIV7.2 construct”. Codon optimization was done using the GeneArt online Algorithm. [0111] The open reading frames contained a leader sequenced, the EGFR806CAR construct, the hinge region of IgG4, the transmembrane domain CD28tm, the signaling domains 41BB and CD3ζ, the self-cleaving peptides P2A and T2A, the drug selection marker DHFRdm, and the surface marker EGFRt. This entire region was codon optimized for expression in humans in SEQ ID NO: 10. [0112] As disclosed herein, the inventors inserted the three constructs into human primary T cells (FIG. 2). The inventors stimulated polyclonal expansion of primary human T cells with CD3:CD28 beads. After 24 hours, lentiviral particles containing one of the three sequences were mixed with protamine sulfate and added to the primary T cells composed of CD4 and CD8 cells at 1:1 ratio. “Mock cells”, to which only protamine sulfate was added, is referenced hereafter as the negative control. At a total of three days after stimulation, the inventors began methotrexate (MTX) selection. At a total of seven days after stimulation, inventors began fluorescence-activated cell sorting (FACS) flow cytometry analysis. At a total of twelve days after stimulation, the inventors continued FACS analysis, then performed rapid expansion and froze cells for future in vivo studies. At a total of 26 days after stimulation, the inventors performed post-expansion assays, including FACS analysis, western blot analysis, cytokine release, chromium release, and ddPCR. Example 2—Human codon optimized EGFR806CAR construct had enhanced expression in T cells [0113] As disclosed herein, the inventors established the expression of EGFR806CAR construct from all three sequence variants and a mock control in human primary T cells. Six days post transduction and four days post methotrexate (MTX) selection, the primary human T cells were stained with anti-EGFR-Biotin and Streptavidin-APC (FIG. 3). Surprisingly, the inventors found that the long promoter enhanced expression, and that the human codon optimized variant further dramatically enhanced expression in T cells. Eleven days post transduction, this trend of significantly enhanced expression of the truncated EGFR (EGFRt) continued (FIG. 4A). Also tested was CAR expression through staining with either EGFRvIII-his and anti-his-APC (FIG.4B), or Protein L-Biotin and Streptavidin-BV405 (FIG. 4C). Both EGFRvIII (CAR antigen) and Protein L bind to 806CAR. Similar to EGFRt expression, CAR expression was shown to be significantly higher in T cells containing the human codon optimized sequence. Even 7 days post rapid expansion, the human codon optimized sequence showed significantly higher EGFRt and CAR expression (FIG. 5A, FIG. 5B). [0114] Also disclosed herein, the inventors tested expression and protein processing of the CARs in parallel to flow cytometry using western blot analysis (FIG. 6A). Protein lysate were collected, and the western blot ran using standard methods. The western blot was visualized using an anti-CD3 zeta antibody. The molecular weight of the CAR is about 50kD and the endogenous zeta is about 15kD. The positive control is H9 cells expressing 806CAR (>99% pure by flow). The results of the western blot were the same as those shown by flow cytometry; expression was enhanced slightly by introducing a long promoter, and significantly enhanced by introducing a long promoter and codon optimized open reading frame. [0115] As a control, the inventors also assessed whether the high expression from the human codon optimized EGFR806CAR construct was caused by a high gene copy number in the cells. They tested this using droplet digital (dd) PCR under standard methods (FIG. 9). ddPCR was conducted using WPRE primers that target the lenti-viral backbone region integrated together with the gene of interest (806CAR-DHFRdm-EGFRt) in the genome. As shown in the drawing, the average copy number per cell was surprisingly lower in the human codon optimized EGFR806CAR construct compared with the long and short promoter sequences. This demonstrated that the effect shown is from high gene expression, rather than the genetic copy number. [0116] In additional experiments, human T cells from donors were transduced with constructs depicted in FIG.1A, FIG.1B, and FIG.1C, and selected with methotrexate. At day 14, the cells were stained with an 806CAR antigen, EGFRvIII-His, followed by secondary staining using anti-His-PE. The level of staining was measured using FACS analysis (FIG. 5C). FIG.5D depicts a bar graph of median fluorescence intensity (MFI) quantification of the PE dye in CD8+ cells. Selected cells were also stained for the EGFRt marker using Erbitux- biotin, and a secondary reagent, streptavidin-PE. The level of staining was measured using FACS analysis (FIG. 5E). FIG. 5F depicts a bar graph MFI quantification of the PE dye in CD8+ cells. Cell surface expression of 806CAR was significantly increased in cells containing the long-promoter-codon optimized construct (coHIV7.3) compared to cells containing the long promoter construct (HIV7.3) or short promoter construct (HIV7.2). [0117] Expression and protein processing of the CARs in parallel to flow cytometry using western blot analysis (FIG. 6B). The density of each CAR molecule band on the western blot was quantified and normalized by the endogenous CD3 zeta signal, which was plotted as the bar graph (FIG.6C). Gene copy number for the constructs in the cells was tested this using droplet digital (dd) PCR under standard methods (FIG.6D, FIG.6E). FIG 6E depicts normalized CD3 zeta intensity from FIG.6C and normalized again by the average copy number per cell. Cells containing the long promoter construct (HIV7.3) and human codon optimized construct (coHIV7.3) had a similar copy number, and this copy number was about half of that for cells containing the short promoter construct (HIV7.2). In view of the FACS analysis and Western blot analysis, the human codon optimized construct (coHIV7.3) had the expression efficiency of the three constructs. Constructs with the long promoter (EF1a(L)) had higher transcription activity than the construct with the short promoter (EF1a(S)). In addition, codon optimization improved gene expression. Example 3—Human codon optimized EGFR806CAR construct increased cytokine release [0118] As disclosed herein, the inventors analyzed whether the enhanced expression from the human codon optimized EGFR806CAR construct led to enhanced cytokine release. This was tested using a cytokine release assay (BioPlex) (FIG.7A, FIG. 7B, FIG. 7C). The K562 parental line and K562/OKT3 were used as the negative and positive controls, respectively. K563 is an antigen-presenting cell, and OKT3 is an anti-TCR antibody that is expressed on K562 as a positive control. K562/EGFRvIII line is a target line of 806CAR T cells. As depicted in the drawings, IL2, TNF-a, and IFN-g all showed enhanced release with the human codon optimized EGFR806CAR construct. This consistently demonstrated that higher EGFR806CAR expression correlates with greater cytokine release. [0119] In additional experiments, human T cells from donors were transduced with constructs depicted in FIG. 1A, FIG. 1B, and FIG. 1C, and selected with methotrexate. The transduced effector cells were challenged with target cells expressing CAR targets in a cytokine release assay for IL2, TNFs and IFNg. K562 parental line and K562/OKT3 were negative and positive controls respectively. K562/EGFRvIII line was an 806CAR T cell target line. As shown in FIG. 7D, cells containing the coHIV7.3 construct had the highest cytokine release upon Ag+ tumor stimulation. Example 4—Human codon optimized EGFR806CAR construct functioned optimally in real tumor lines [0120] As disclosed herein, the inventors analyzed whether the enhanced expression from the human codon optimized EGFR806CAR construct correlated with cytotoxicity (FIG. 8A). Cytotoxicity was assessed using a chromium release assay under standard conditions. As in the cytokine assay, the K562 parental line and K562/OKT3 were used as negative and positive controls, respectively. K562/EGFRvIII line is an engineered target line of 806CAR T cells expressing exogenous EGFRvIII. The effector to target cell ratio ranged from 30:1 to 1:1. All three CAR T cells showed high cytotoxicity using K562 cells expressing EGFRvIII and differential cytotoxicity using Be2 and U87 tumor lines. The data disclosed herein provide evidence of the benefit of using codon optimized EGFR806CAR construct T cells for addressing low antigen expressing cells, which are usually real tumor lines, and not an artificial tumor line such as K562/EGFRvIII. [0121] In additional experiments, human T cells from donors were transduced with constructs depicted in FIG. 1A, FIG. 1B, and FIG. 1C, and selected with methotrexate. The transduced effector cells were challenged with target cells expressing CAR targets in a cytotoxicity assay (chromium release assay). As shown in FIG. 8B, all 806CAR T cells showed effective killing of target Ag+ tumor cells. Cells containing coHIV7.2 had the highest cytolytic activity to the natural tumor lines, Be2 and U87 compared to cells containing HIV7.3 or HIV7.2. [0122] In additional experiments, human T cells from donors were transduced with constructs depicted in FIG. 1A, FIG. 1B, and FIG. 1C, and selected with methotrexate. The transduced effector cells were challenged twice with different target tumor cells expressing mCherry marker at E:T ratio of 2:1 at 0 hr and 96 hr. The mCherry signal was collected by Incucyte. K562 cell line was a negative control, K562/OKTs was a positive control, K562/EGFRVIII and Be2 were CAR specific target lines. As shown in FIG. 8C, cells containing the coHIV7.3 construct significantly suppressed the growth of K562/EGFRVIII and Be2 cells after each tumor challenge. Cells containing the HIV7.3 construct or the HIV7.2 construct could not suppress the K562/EGFRVIII tumor cell growth after the second challenge. Cells containing the HIV7.3 construct or the HIV7.3 construct did not inhibit Be2 (a low tumor antigen cell line) tumor cell growth. Example 5—Human codon optimized EGFR806CAR construct conferred significant therapeutic benefits in vivo [0123] As disclosed herein, the performance of T cells containing the human codon optimized EGFR806CAR construct were tested in vivo. Sequences containing the short promoter construct, or the long promoter and the human codon optimized construct were transduced into T cells before being studied in an intracranial NSG mouse model (FIG. 10A). T cells were used at a low dose (non-curative) to be able to detect the difference between the testing groups. Each testing group contained 5 mice. U87 glioma cells (806CAR target) expressing GFP:ffluc (GFP and firefly luciferase fusion protein) were injected intracranially (i.c.). A week later, T cells were i.c. injected. Bioluminescence images were taken at least once a week and the signal quantification is shown. As depicted in the drawings, mice with the human codon optimized EGFR806CAR construct had significantly lower bioluminescence after T cell injection, indicating a reduction in tumor formation (FIG. 10B). Similarly, these mice had a higher survival rate from tumor related death over-time compared with the negative control and mice given EGFR806CAR construct with a short promoter (FIG. 10C). Collectively, this data indicated that the human codon optimized EGFR806CAR construct with long promoter (SEQ ID NO: 10) has higher expression, enhanced cytokine release, greater performance in real tumor cells, and greater performance in vivo. [0124] In additional experiments, human T cells from donors were transduced with constructs depicted in FIG. 1A, FIG. 1B, and FIG. 1C, and selected with methotrexate. Transduced cells were studied in the intracranial NSG mouse model. T cells were used at a low dose (non-curative) to be able to detect the difference between the testing groups. Each testing group contained 5 mice. U87 glioma cells (806CAR target) expressing GFP:ffluc (GFP and firefly luciferase fusion protein) were injected intracranially (i.c.). A week later, T cells were i.c. injected. Bioluminescence images were taken at least once a week and the signal quantified (FIG.10D). A Kaplan Meier analysis was performed (FIG.10E). All mice injected with cells containing the coHIV7.3 construct survived through 90 days without symptoms. The rest of the mice were euthanized for tumor related symptoms.
