     BACKGROUND OF THE INVENTION 
     Some cancers may have very limited treatment options, particularly when the cancer becomes metastatic and unresectable. Despite advances in treatments such as, for example, surgery, chemotherapy, and radiation therapy, the prognosis for many cancers, such as, for example, pancreatic, colorectal, lung, endometrial, ovarian, and prostate cancers, may be poor. Accordingly, there exists an unmet need for additional treatments for cancer.

     DETAILED DESCRIPTION OF THE INVENTION 
     Tumor Protein P53 (also referred to as “TP53” or “p53”) acts as a tumor suppressor by, for example, regulating cell division. The p53 protein is located in the nucleus of the cell, where it binds directly to DNA. When DNA becomes damaged, the p53 protein is involved in determining whether the DNA will be repaired or the damaged cell will undergo apoptosis. If the DNA can be repaired, p53 activates other genes to fix the damage. If the DNA cannot be repaired, the p53 protein prevents the cell from dividing and signals it to undergo apoptosis. By stopping cells with mutated or damaged DNA from dividing, p53 helps prevent the development of tumors. Wild-type (WT) (normal) full-length p53 comprises the amino acid sequence of SEQ ID NO: 1. 
     Mutations in the p53 protein may reduce or eliminate the p53 protein&#39;s tumor suppressor function. Alternatively or additionally, a p53 mutation may be a gain-of-function mutation by interfering with WT p53 in a dominant negative fashion. Mutated p53 protein may be expressed in any of a variety of human cancers such as, for example, cholangiocarcinoma, melanoma, colon cancer, rectal cancer, ovarian cancer, endometrial cancer, non-small cell lung cancer (NSCLC), glioblastoma, uterine cervical cancer, head and neck cancer, breast cancer, pancreatic cancer, or bladder cancer. 
     An embodiment of the invention provides an isolated or purified T cell receptor (TCR) having antigenic specificity for mutated human p53 (hereinafter, “mutated p53”). Hereinafter, references to a “TCR” also refer to functional portions and functional variants of the TCR, unless specified otherwise. Mutations of p53 are defined herein by reference to the amino acid sequence of full-length, WT p53 (SEQ ID NO: 1). Thus, mutations of p53 are described herein by reference to the amino acid residue present at a particular position, followed by the position number, followed by the amino acid with which that residue has been replaced in the particular mutation under discussion. For example, when the positions are as defined by SEQ ID NO: 1, the term “R175” refers to the arginine present at position 175 of SEQ ID NO: 1, “R175H” indicates that the arginine present at position 175 of SEQ ID NO: 1 is replaced by histidine, while “G245S” indicates that the glycine present at position 245 of SEQ ID NO: 1 has been replaced with serine. P53 has nine known splice variants. The p53 mutations described herein are conserved over all nine p53 splice variants. An alignment of the nine p53 splice variants is shown in  FIG. 35 . Accordingly, T cells isolated by the inventive methods may have antigenic specificity for any mutated p53 amino acid sequence described herein encoded by any of the nine p53 splice variants. When the positions are as defined by SEQ ID NO: 1, then the actual positions of the amino acid sequence of a particular splice variant of p53 are defined relative to the corresponding positions of SEQ ID NO: 1, and the positions as defined by SEQ ID NO: 1 may be different than the actual positions in a particular splice variant. Thus, for example, mutations refer to a replacement of an amino acid residue in the amino acid sequence of a particular splice variant of p53 corresponding to the indicated position of the 393-amino acid sequence of SEQ ID NO: 1 with the understanding that the actual positions in the splice variant may be different. 
     In an embodiment of the invention, the TCR has antigenic specificity for human p53 with a mutation at position 175, 220, 245, 248, 249, 273, or 282 of SEQ ID NO: 1. The TCR may have antigenic specificity for human p53 with a mutation at position 175, 220, 245, or 248 of SEQ ID NO: 1. The p53 mutation may be any missense mutation. Accordingly, the mutation at position 175, 220, 245, 248, 249, 273, or 282 of SEQ ID NO: 1 may be a substitution of the native (WT) amino acid residue present at position 175, 220, 245, 248, 249, 273, or 282 of SEQ ID NO: 1 with any amino acid residue other than the native (WT) amino acid residue present at the particular position under discussion. In an embodiment of the invention, the TCR has antigenic specificity for human p53 with one of the following human p53 mutations: R175H, Y220C, G245D, G245S, R248L, R248Q, R248W, R249S, R273H, R273C, R273L, or R282W. The TCR may have antigenic specificity for human p53 with one of the following human p53 mutations: R175H, Y220C, G245S, R248Q, or R248W. For example, the inventive TCR may have antigenic specificity for a mutated p53 amino acid sequence selected from the group consisting of SEQ ID NOs: 2-13. 
     In an embodiment of the invention, the inventive TCRs may be able to recognize mutated p53 in an HLA (human leukocyte antigen)-molecule-dependent manner. “HLA-molecule-dependent manner,” as used herein, means that the TCR elicits an immune response upon binding to mutated p53 within the context of an HLA molecule, which HLA molecule is expressed by the patient from which the TCR was isolated. The inventive TCRs may be able to recognize mutated p53 that is presented by the applicable HLA molecule and may bind to the HLA molecule in addition to mutated p53. 
     The TCRs of the invention provide many advantages, including when expressed by cells used for adoptive cell transfer. Mutated p53 is expressed by cancer cells and is not expressed by normal, noncancerous cells. Without being bound to a particular theory or mechanism, it is believed that the inventive TCRs advantageously target the destruction of cancer cells while minimizing or eliminating the destruction of normal, non-cancerous cells, thereby reducing, for example, by minimizing or eliminating, toxicity. Moreover, the inventive TCRs may, advantageously, successfully treat or prevent mutated p53-positive cancers that do not respond to other types of treatment such as, for example, chemotherapy, surgery, or radiation. Additionally, the inventive TCRs may provide highly avid recognition of mutated p53, which may provide the ability to recognize unmanipulated tumor cells (e.g., tumor cells that have not been treated with interferon (IFN)-γ, transfected with a vector encoding one or both of mutated p53 and the applicable HLA molecule, pulsed with a p53 peptide with the p53 mutation, or a combination thereof). Roughly half of all tumors harbor a mutation in p53, about half of which will be a missense mutation and about 30% of the missense mutations occur at the following “hotspot” residues: R175H, Y220C, G245D, G245S, R248L, R248Q, R248W, R249S, R273C, R273L, R273H and R282W. Moreover, the same “hotspot” mutations in p53 (e.g., R175H, Y220C, G245D, G245S, R248L, R248Q, R248W, R249S, R273H, R273C, R273L, or R282W) occur frequently (cumulatively about 30% of the p53 missense mutations) in tumors of unrelated people. Accordingly, the inventive TCRs may increase the number of patients who may be eligible for treatment with immunotherapy. 
     The phrase “antigenic specificity,” as used herein, means that the TCR can specifically bind to and immunologically recognize mutated p53 with high avidity. For example, a TCR may be considered to have “antigenic specificity” for mutated p53 if about 1×10 4  to about 1×10 5  T cells expressing the TCR secrete at least about 200 pg/mL or more (e.g., 200 pg/mL or more, 300 pg/mL or more, 400 pg/mL or more, 500 pg/mL or more, 600 pg/mL or more, 700 pg/mL or more, 1000 pg/mL or more, 5,000 pg/mL or more, 7,000 pg/mL or more, 10,000 pg/mL or more, 20,000 pg/mL or more, or a range defined by any two of the foregoing values) of IFN-γ upon co-culture with (a) antigen-negative, applicable HLA molecule positive target cells pulsed with a low concentration of mutated p53 peptide (e.g., about 0.05 ng/mL to about 5 ng/mL, 0.05 ng/mL, 0.1 ng/mL, 0.5 ng/mL, 1 ng/mL, 5 ng/mL, or a range defined by any two of the foregoing values) or (b) antigen-negative, applicable HLA molecule positive target cells into which a nucleotide sequence encoding mutated p53 has been introduced such that the target cell expresses mutated p53. Cells expressing the inventive TCRs may also secrete IFN-γ upon co-culture with antigen-negative, applicable HLA molecule positive target cells pulsed with higher concentrations of mutated p53 peptide. 
     Alternatively or additionally, a TCR may be considered to have “antigenic specificity” for mutated p53 if T cells expressing the TCR secrete at least twice as much IFN-γ upon co-culture with (a) antigen-negative, applicable HLA molecule positive target cells pulsed with a low concentration of mutated p53 peptide or (b) antigen-negative, applicable HLA molecule positive target cells into which a nucleotide sequence encoding mutated p53 has been introduced such that the target cell expresses mutated p53 as compared to the amount of IFN-γ expressed by a negative control. The negative control may be, for example, (i) T cells expressing the TCR, co-cultured with (a) antigen-negative, applicable HLA molecule positive target cells pulsed with the same concentration of an irrelevant peptide (e.g., some other peptide with a different sequence from the mutated p53 peptide) or (b) antigen-negative, applicable HLA molecule positive target cells into which a nucleotide sequence encoding an irrelevant peptide has been introduced such that the target cell expresses the irrelevant peptide, or (ii) untransduced T cells (e.g., derived from PBMC, which do not express the TCR) co-cultured with (a) antigen-negative, applicable HLA molecule positive target cells pulsed with the same concentration of mutated p53 peptide or (b) antigen-negative, applicable HLA molecule positive target cells into which a nucleotide sequence encoding mutated p53 has been introduced such that the target cell expresses mutated p53. IFN-γ secretion may be measured by methods known in the art such as, for example, enzyme-linked immunosorbent assay (ELISA). 
     Alternatively or additionally, a TCR may be considered to have “antigenic specificity” for mutated p53 if at least twice as many of the numbers of T cells expressing the TCR secrete IFN-γ upon co-culture with (a) antigen-negative, applicable HLA molecule positive target cells pulsed with a low concentration of mutated p53 peptide or (b) antigen-negative, applicable HLA molecule positive target cells into which a nucleotide sequence encoding mutated p53 has been introduced such that the target cell expresses mutated p53 as compared to the numbers of negative control T cells that secrete IFN-γ. The concentration of peptide and the negative control may be as described herein with respect to other aspects of the invention. The numbers of cells secreting IFN-γ may be measured by methods known in the art such as, for example, enzyme-linked immunospot (ELISOT) assay. 
     Alternatively or additionally, a TCR may be considered to have “antigenic specificity” for mutated p53 if at least twice as many spots are detected by ELISPOT for the T cells expressing the TCR upon co-culture with (a) antigen-negative, applicable HLA molecule positive target cells pulsed with a low concentration of mutated p53 peptide or (b) antigen-negative, applicable HLA molecule positive target cells into which a nucleotide sequence encoding mutated p53 has been introduced such that the target cell expresses mutated p53 as compared to the number of spots detected by ELISPOT for negative control T cells co-cultured with the same target cells. The concentration of peptide and the negative control may be as described herein with respect to other aspects of the invention. 
     Alternatively or additionally, a TCR may be considered to have “antigenic specificity” for mutated p53 if greater than about 50 spots are detected by ELISPOT for the T cells expressing the TCR upon co-culture with (a) antigen-negative, applicable HLA molecule positive target cells pulsed with a low concentration of mutated p53 peptide or (b) antigen-negative, applicable HLA molecule positive target cells into which a nucleotide sequence encoding mutated p53 has been introduced such that the target cell expresses mutated p53. The concentration of peptide may be as described herein with respect to other aspects of the invention. 
     Alternatively or additionally, a TCR may be considered to have “antigenic specificity” for mutated p53 if T cells expressing the TCR upregulate expression of one or both of 4-1BB and OX40 as measured by, for example, flow cytometry after stimulation with target cells expressing mutated p53. 
     The invention provides a TCR comprising two polypeptides (i.e., polypeptide chains), such as an alpha (a) chain of a TCR, a beta (P) chain of a TCR, a gamma (γ) chain of a TCR, a delta (5) chain of a TCR, or a combination thereof. The polypeptides of the inventive TCR can comprise any amino acid sequence, provided that the TCR has antigenic specificity for mutated p53.

Each one of the foregoing 47 collections of amino acid sequences in this paragraph sets forth the two variable regions of each of 47 different TCRs having antigenic specificity for mutated human p53. The two amino acid sequences in each collection correspond to the variable region of the α chain and the variable region of the β chain of a TCR, respectively. 
     The inventive TCRs may further comprise a constant region. The constant region may be derived from any suitable species such as, e.g., human or mouse. In an embodiment of the invention, the TCRs further comprise a murine constant region. As used herein, the term “murine” or “human,” when referring to a TCR or any component of a TCR described herein (e.g., complementarity determining region (CDR), variable region, constant region, alpha chain, and/or beta chain), means a TCR (or component thereof) which is derived from a mouse or a human, respectively, i.e., a TCR (or component thereof) that originated from or was, at one time, expressed by a mouse T cell or a human T cell, respectively. In an embodiment of the invention, the TCR may comprise a murine α chain constant region and a murine β chain constant region. The murine α chain constant region may be modified or unmodified. A modified murine α chain constant region may be, e.g., cysteine-substituted, LVL-modified, or both cysteine-substituted and LVL-modified, as described, for example, in US 2017/0145070. The murine β chain constant region may be modified or unmodified. A modified murine β chain constant region may be, e.g., cysteine-substituted, as described, for example, in US 2017/0145070. In an embodiment of the invention, the TCR comprises a cysteine-substituted, LVL-modified murine α chain constant region comprising the amino acid sequence of SEQ ID NO: 23 or 24. In an embodiment of the invention, the TCR comprises a cysteine-substituted murine β chain constant region comprising the amino acid sequence of SEQ ID NO: 25. 
     In an embodiment of the invention, the inventive TCR can comprise an α chain of a TCR and a β chain of a TCR. The α chain of the TCR may comprise a variable region of an α chain and a constant region of an α chain. An α chain of this type can be paired with any 1 chain of a TCR. The β chain may comprise a variable region of a β chain and a constant region of a ρβ chain. In an embodiment of the invention, the TCR comprises the amino acid sequences of: (1) both of SEQ ID NOs: 35-36; (2) both of SEQ ID NOs: 45-46; (3) both of SEQ ID NOs: 55-56; (4) both of SEQ ID NOs: 65-66; (5) both of SEQ ID NOs: 75-76; (6) both of SEQ ID NOs: 85-86; (7) both of SEQ ID NOs: 95-96; (8) both of SEQ ID NOs: 105-106; (9) both of SEQ ID NOs: 115-116; (10) both of SEQ ID NOs: 125-126; (11) both of SEQ ID NOs: 135-136; (12) both of SEQ ID NOs: 145-146; (13) both of SEQ ID NOs: 155-156; (14) both of SEQ ID NOs: 165-166; (15) both of SEQ ID NOs: 175-176; (16) both of SEQ ID NOs: 185-186; (17) both of SEQ ID NOs: 195-196; (18) both of SEQ ID NOs: 205-206; (19) both of SEQ ID NOs: 215-216; (20) both of SEQ ID NOs: 225-226; (21) both of SEQ ID NOs: 235-236; (22) both of SEQ ID NOs: 245-246; (23) both of SEQ ID NOs: 255-256; (24) both of SEQ ID NOs: 265-266; (25) both of SEQ ID NOs: 275-276; (26) both of SEQ ID NOs: 285-286; (27) both of SEQ ID NOs: 295-296; (28) both of SEQ ID NOs: 305-306; (29) both of SEQ ID NOs: 315-316; (30) both of SEQ ID NOs: 325-326; (31) both of SEQ ID NOs: 335-336; (32) both of SEQ ID NOs: 345-346; (33) both of SEQ ID NOs: 355-356; (34) both of SEQ ID NOs: 365-366; (35) both of SEQ ID NOs: 375-376; (36) both of SEQ ID NOs: 385-386; (37) both of SEQ ID NOs: 395-396; (38) both of SEQ ID NOs: 405-406; (39) both of SEQ ID NOs: 415-416; (40) both of SEQ ID NOs: 425-426; (41) both of SEQ ID NOs: 435-436; (42) both of SEQ ID NOs: 445-446; (43) both of SEQ ID NOs: 455-456; (44) both of SEQ ID NOs: 465-466; (45) both of SEQ ID NOs: 475-476; (46) both of SEQ ID NOs: 485-486; or (47) both of SEQ ID NOs: 495-496. Each one of the foregoing 47 collections of amino acid sequences in this paragraph sets forth the α chain and β chain of each of 47 different TCRs having antigenic specificity for mutated human p53. The two amino acid sequences in each collection correspond to the α chain and the β chain of a TCR, respectively. 
     Included in the scope of the invention are functional variants of the inventive TCRs described herein. The term “functional variant,” as used herein, refers to a TCR, polypeptide, or protein having substantial or significant sequence identity or similarity to a parent TCR, polypeptide, or protein, which functional variant retains the biological activity of the TCR, polypeptide, or protein of which it is a variant. Functional variants encompass, for example, those variants of the TCR, polypeptide, or protein described herein (the parent TCR, polypeptide, or protein) that retain the ability to specifically bind to mutated p53 for which the parent TCR has antigenic specificity or to which the parent polypeptide or protein specifically binds, to a similar extent, the same extent, or to a higher extent, as the parent TCR, polypeptide, or protein. In reference to the parent TCR, polypeptide, or protein, the functional variant can, for instance, be at least about 30%, at least about 50%, at least about 75%, at least about 80%, at least about 90%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99% or more identical in amino acid sequence to the parent TCR, polypeptide, or protein, respectively. 
     The functional variant can, for example, comprise the amino acid sequence of the parent TCR, polypeptide, or protein with at least one conservative amino acid substitution. Conservative amino acid substitutions are known in the art, and include amino acid substitutions in which one amino acid having certain physical and/or chemical properties is exchanged for another amino acid that has the same chemical or physical properties. For instance, the conservative amino acid substitution can be an acidic amino acid substituted for another acidic amino acid (e.g., Asp or Glu), an amino acid with a nonpolar side chain substituted for another amino acid with a nonpolar side chain (e.g., Ala, Gly, Val, Ile, Leu, Met, Phe, Pro, Trp, Val, etc.), a basic amino acid substituted for another basic amino acid (Lys, Arg, etc.), an amino acid with a polar side chain substituted for another amino acid with a polar side chain (Asn, Cys, Gin, Ser, Thr, Tyr, etc.), etc. 
     Alternatively or additionally, the functional variants can comprise the amino acid sequence of the parent TCR, polypeptide, or protein with at least one non-conservative amino acid substitution. In this case, it is preferable for the non-conservative amino acid substitution to not interfere with or inhibit the biological activity of the functional variant. Preferably, the non-conservative amino acid substitution enhances the biological activity of the functional variant, such that the biological activity of the functional variant is increased as compared to the parent TCR, polypeptide, or protein. 
     The TCR, polypeptide, or protein can consist essentially of the specified amino acid sequence or sequences described herein, such that other components of the TCR, polypeptide, or protein, e.g., other amino acids, do not materially change the biological activity of the TCR, polypeptide, or protein. 
     Also provided by the invention is a polypeptide comprising a functional portion of any of the TCRs described herein. The term “polypeptide,” as used herein, includes oligopeptides and refers to a single chain of amino acids connected by one or more peptide bonds. 
     With respect to the inventive polypeptides, the functional portion can be any portion comprising contiguous amino acids of the TCR of which it is a part, provided that the functional portion specifically binds to mutated p53. The term “functional portion,” when used in reference to a TCR, refers to any part or fragment of the TCR of the invention, which part or fragment retains the biological activity of the TCR of which it is a part (the parent TCR). Functional portions encompass, for example, those parts of a TCR that retain the ability to specifically bind to mutated p53 (e.g., in an applicable HLA molecule-dependent manner), or detect, treat, or prevent cancer, to a similar extent, the same extent, or to a higher extent, as the parent TCR. In reference to the parent TCR, the functional portion can comprise, for instance, about 10%, about 25%, about 30%, about 50%, about 68%, about 80%, about 90%, about 95%, or more, of the parent TCR. 
     The functional portion can comprise additional amino acids at the amino or carboxy terminus of the portion, or at both termini, which additional amino acids are not found in the amino acid sequence of the parent TCR. Desirably, the additional amino acids do not interfere with the biological function of the functional portion, e.g., specifically binding to mutated p53; and/or having the ability to detect cancer, treat or prevent cancer, etc. More desirably, the additional amino acids enhance the biological activity, as compared to the biological activity of the parent TCR. 
     The polypeptide can comprise a functional portion of either or both of the α and β chains of the TCRs of the invention, such as a functional portion comprising one of more of CDR1, CDR2, and CDR3 of the variable region(s) of the α chain and/or β chain of a TCR of the invention. In an embodiment of the invention, the polypeptide can comprise a functional portion comprising the amino acid sequences of: (1) all of SEQ ID NOs: 27-32; (2) all of SEQ ID NOs: 37-42; (3) all of SEQ ID NOs: 47-52; (4) all of SEQ ID NOs: 57-62; (5) all of SEQ ID NOs: 67-72; (6) all of SEQ ID NOs: 77-82; (7) all of SEQ ID NOs: 87-92; (8) all of SEQ ID NOs: 97-102; (9) all of SEQ ID NOs: 107-112; (10) all of SEQ ID NOs: 117-122; (11) all of SEQ ID NOs: 127-132; (12) all of SEQ ID NOs: 137-142; (13) all of SEQ ID NOs: 147-152; (14) all of SEQ ID NOs: 157-162; (15) all of SEQ ID NOs: 167-172; (16) all of SEQ ID NOs: 177-182; (17) all of SEQ ID NOs: 187-192; (18) all of SEQ ID NOs: 197-202; (19) all of SEQ ID NOs: 207-212; (20) all of SEQ ID NOs: 217-222; (21) all of SEQ ID NOs: 227-232; (22) all of SEQ ID NOs: 237-242; (23) all of SEQ ID NOs: 247-252; (24) all of SEQ ID NOs: 257-262; (25) all of SEQ ID NOs: 267-272; (26) all of SEQ ID NOs: 277-282; (27) all of SEQ ID NOs: 287-292; (28) all of SEQ ID NOs: 297-302; (29) all of SEQ ID NOs: 307-312; (30) all of SEQ ID NOs: 317-322; (31) all of SEQ ID NOs: 327-332; (32) all of SEQ ID NOs: 337-342; (33) all of SEQ ID NOs: 347-352; (34) all of SEQ ID NOs: 357-362; (35) all of SEQ ID NOs: 367-372; (36) all of SEQ ID NOs: 377-382; (37) all of SEQ ID NOs: 387-392; (38) all of SEQ ID NOs: 397-402; (39) all of SEQ ID NOs: 407-412; (40) all of SEQ ID NOs: 417-422; (41) all of SEQ ID NOs: 427-432; (42) all of SEQ ID NOs: 437-442; (43) all of SEQ ID NOs: 447-452; (44) all of SEQ ID NOs: 457-462; (45) all of SEQ ID NOs: 467-472; (46) all of SEQ ID NOs: 477-482; or (47) all of SEQ ID NOs: 487-492.

(Gaithersburg, Md.), and Multiple Peptide Systems (San Diego, Calif.). In this respect, the inventive TCRs, polypeptides, and proteins can be synthetic, recombinant, isolated, and/or purified. 
     An embodiment of the invention provides a nucleic acid comprising a nucleotide sequence encoding any of the TCRs, polypeptides, or proteins described herein. “Nucleic acid,” as used herein, includes “polynucleotide,” “oligonucleotide,” and “nucleic acid molecule,” and generally means a polymer of DNA or RNA, which can be single-stranded or double-stranded, which can contain natural, non-natural or altered nucleotides, and which can contain a natural, non-natural or altered internucleotide linkage, such as a phosphoroamidate linkage or a phosphorothioate linkage, instead of the phosphodiester found between the nucleotides of an unmodified oligonucleotide. In an embodiment, the nucleic acid comprises complementary DNA (cDNA). It is generally preferred that the nucleic acid does not comprise any insertions, deletions, inversions, and/or substitutions. However, it may be suitable in some instances, as discussed herein, for the nucleic acid to comprise one or more insertions, deletions, inversions, and/or substitutions. 
     Preferably, the nucleic acids of the invention are recombinant. As used herein, the term “recombinant” refers to (i) molecules that are constructed outside living cells by joining natural or synthetic nucleic acid segments to nucleic acid molecules that can replicate in a living cell, or (ii) molecules that result from the replication of those described in (i) above. For purposes herein, the replication can be in vitro replication or in vivo replication. 
     The nucleic acids can be constructed based on chemical synthesis and/or enzymatic ligation reactions using procedures known in the art. See, for example, Green and Sambrook et al., supra. For example, a nucleic acid can be chemically synthesized using naturally occurring nucleotides or variously modified nucleotides designed to increase the biological stability of the molecules or to increase the physical stability of the duplex formed upon hybridization (e.g., phosphorothioate derivatives and acridine substituted nucleotides). Examples of modified nucleotides that can be used to generate the nucleic acids include, but are not limited to, 5-fluorouracil, 5-bromouracil, 5-chlorouracil, 5-iodouracil, hypoxanthine, xanthine, 4-acetylcytosine, 5-(carboxyhydroxymethyl) uracil, 5-carboxymethylaminomethyl-2-thiouridine, 5-carboxymethylaminomethyluracil, dihydrouracil, beta-D-galactosylqueosine, inosine, N 6 -isopentenyladenine, I-methylguanine, 1-methylinosine, 2,2-dimethylguanine, 2-methyladenine, 2-methylguanine, 3-methylcytosine, 5-methylcytosine, N 6 -substituted adenine, 7-methylguanine, 5-methylaminomethyluracil, 5-methoxyaminomethyl-2-thiouracil, beta-D-mannosylqueosine, 5′-methoxycarboxymethyluracil, 5-methoxyuracil, 2-methylthio-N 6 -isopentenyladenine, uracil-5-oxyacetic acid (v), wybutoxosine, pseudouracil, queosine, 2-thiocytosine, 5-methyl-2-thiouracil, 2-thiouracil, 4-thiouracil, 5-methyluracil, uracil-5-oxyacetic acid methylester, 3-(3-amino-3-N-2-carboxypropyl) uracil, and 2,6-diaminopurine. Alternatively, one or more of the nucleic acids of the invention can be purchased from companies, such as Macromolecular Resources (Fort Collins, Colo.) and Synthegen (Houston, Tex.). 
     In an embodiment of the invention, the nucleic acid comprises a codon-optimized nucleotide sequence encoding any of the TCRs, polypeptides, or proteins described herein. Without being bound to any particular theory or mechanism, it is believed that codon optimization of the nucleotide sequence increases the translation efficiency of the mRNA transcripts. Codon optimization of the nucleotide sequence may involve substituting a native codon for another codon that encodes the same amino acid, but can be translated by tRNA that is more readily available within a cell, thus increasing translation efficiency. Optimization of the nucleotide sequence may also reduce secondary mRNA structures that would interfere with translation, thus increasing translation efficiency. 
     The invention also provides a nucleic acid comprising a nucleotide sequence which is complementary to the nucleotide sequence of any of the nucleic acids described herein or a nucleotide sequence which hybridizes under stringent conditions to the nucleotide sequence of any of the nucleic acids described herein. 
     The nucleotide sequence which hybridizes under stringent conditions preferably hybridizes under high stringency conditions. By “high stringency conditions” is meant that the nucleotide sequence specifically hybridizes to a target sequence (the nucleotide sequence of any of the nucleic acids described herein) in an amount that is detectably stronger than non-specific hybridization. High stringency conditions include conditions which would distinguish a polynucleotide with an exact complementary sequence, or one containing only a few scattered mismatches from a random sequence that happened to have a few small regions (e.g., 3-10 bases) that matched the nucleotide sequence. Such small regions of complementarity are more easily melted than a full-length complement of 14-17 or more bases, and high stringency hybridization makes them easily distinguishable. Relatively high stringency conditions would include, for example, low salt and/or high temperature conditions, such as provided by about 0.02-0.1 M NaCl or the equivalent, at temperatures of about 50-70° C. Such high stringency conditions tolerate little, if any, mismatch between the nucleotide sequence and the template or target strand, and are particularly suitable for detecting expression of any of the inventive TCRs. It is generally appreciated that conditions can be rendered more stringent by the addition of increasing amounts of formamide. 
     The invention also provides a nucleic acid comprising a nucleotide sequence that is at least about 70% or more, e.g., about 80%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, or about 99% identical to any of the nucleic acids described herein. In this regard, the nucleic acid may consist essentially of any of the nucleotide sequences described herein. 
     The nucleic acids of the invention can be incorporated into a recombinant expression vector. In this regard, the invention provides a recombinant expression vector comprising any of the nucleic acids of the invention. In an embodiment of the invention, the recombinant expression vector comprises a nucleotide sequence encoding the α chain, the β chain, and linker peptide. 
     For purposes herein, the term “recombinant expression vector” means a genetically-modified oligonucleotide or polynucleotide construct that permits the expression of an mRNA, protein, polypeptide, or peptide by a host cell, when the construct comprises a nucleotide sequence encoding the mRNA, protein, polypeptide, or peptide, and the vector is contacted with the cell under conditions sufficient to have the mRNA, protein, polypeptide, or peptide expressed within the cell. The vectors of the invention are not naturally-occurring as a whole. However, parts of the vectors can be naturally-occurring. The inventive recombinant expression vectors can comprise any type of nucleotide, including, but not limited to DNA and RNA, which can be single-stranded or double-stranded, synthesized or obtained in part from natural sources, and which can contain natural, non-natural or altered nucleotides. The recombinant expression vectors can comprise naturally-occurring, non-naturally-occurring internucleotide linkages, or both types of linkages. Preferably, the non-naturally occurring or altered nucleotides or internucleotide linkages do not hinder the transcription or replication of the vector. 
     The recombinant expression vector of the invention can be any suitable recombinant expression vector, and can be used to transform or transfect any suitable host cell. Suitable vectors include those designed for propagation and expansion or for expression or both, such as plasmids and viruses. The vector can be selected from the group consisting of the transposon/transposases series, pUC series (Fermentas Life Sciences), the pBluescript series (Stratagene, LaJolla, Calif.), the pET series (Novagen, Madison, Wis.), the pGEX series (Pharmacia Biotech, Uppsala, Sweden), and the pEX series (Clontech, Palo Alto, Calif.). Bacteriophage vectors, such as λGT10, λGT11, λZapII (Stratagene), λEMBL4, and λNM1149, also can be used. Examples of plant expression vectors include pBI01, pBI101.2, pBI101.3, pBI121 and pBIN19 (Clontech). Examples of animal expression vectors include pEUK-Cl, pMAM and pMAMneo (Clontech). Preferably, the recombinant expression vector is a transposon vector or a viral vector, e.g., a retroviral vector. 
     The recombinant expression vectors of the invention can be prepared using standard recombinant DNA techniques described in, for example, Green and Sambrook et al., supra. Constructs of expression vectors, which are circular or linear, can be prepared to contain a replication system functional in a prokaryotic or eukaryotic host cell. Replication systems can be derived, e.g., from ColE1, 2μ plasmid, λ, SV40, bovine papillomavirus, and the like. 
     Desirably, the recombinant expression vector comprises regulatory sequences, such as transcription and translation initiation and termination codons, which are specific to the type of host cell (e.g., bacterium, fungus, plant, or animal) into which the vector is to be introduced, as appropriate and taking into consideration whether the vector is DNA- or RNA-based. 
     The recombinant expression vector can include one or more marker genes, which allow for selection of transformed or transfected host cells. Marker genes include biocide resistance, e.g., resistance to antibiotics, heavy metals, etc., complementation in an auxotrophic host cell to provide prototrophy, and the like. Suitable marker genes for the inventive expression vectors include, for instance, neomycin/G418 resistance genes, hygromycin resistance genes, histidinol resistance genes, tetracycline resistance genes, and ampicillin resistance genes. 
     The recombinant expression vector can comprise a native or nonnative promoter operably linked to the nucleotide sequence encoding the TCR, polypeptide, or protein, or to the nucleotide sequence which is complementary to or which hybridizes to the nucleotide sequence encoding the TCR, polypeptide, or protein. The selection of promoters, e.g., strong, weak, inducible, tissue-specific and developmental-specific, is within the ordinary skill of the artisan. Similarly, the combining of a nucleotide sequence with a promoter is also within the skill of the artisan. The promoter can be a non-viral promoter, e.g., a human elongation factor-1α promoter, or a viral promoter, e.g., a cytomegalovirus (CMV) promoter, an SV40 promoter, an RSV promoter, and a promoter found in the long-terminal repeat of the murine stem cell virus. 
     The inventive recombinant expression vectors can be designed for either transient expression, for stable expression, or for both. Also, the recombinant expression vectors can be made for constitutive expression or for inducible expression. 
     Further, the recombinant expression vectors can be made to include a suicide gene. As used herein, the term “suicide gene” refers to a gene that causes the cell expressing the suicide gene to die. The suicide gene can be a gene that confers sensitivity to an agent, e.g., a drug, upon the cell in which the gene is expressed, and causes the cell to die when the cell is contacted with or exposed to the agent. Suicide genes are known in the art and include, for example, the Herpes Simplex Virus (HSV) thymidine kinase (TK) gene, cytosine daminase, purine nucleoside phosphorylase, and nitroreductase. 
     Another embodiment of the invention further provides a host cell comprising any of the recombinant expression vectors described herein. As used herein, the term “host cell” refers to any type of cell that can contain the inventive recombinant expression vector. The host cell can be a eukaryotic cell, e.g., plant, animal, fungi, or algae, or can be a prokaryotic cell, e.g., bacteria or protozoa. The host cell can be a cultured cell or a primary cell, i.e., isolated directly from an organism, e.g., a human. The host cell can be an adherent cell or a suspended cell, i.e., a cell that grows in suspension. Suitable host cells are known in the art and include, for instance, DH5a  E. coli  cells, Chinese hamster ovarian cells, monkey VERO cells, COS cells, HEK293 cells, and the like. For purposes of amplifying or replicating the recombinant expression vector, the host cell is preferably a prokaryotic cell, e.g., a DH5a cell. For purposes of producing a recombinant TCR, polypeptide, or protein, the host cell is preferably a mammalian cell. Most preferably, the host cell is a human cell. While the host cell can be of any cell type, can originate from any type of tissue, and can be of any developmental stage, the host cell preferably is a peripheral blood lymphocyte (PBL) or a peripheral blood mononuclear cell (PBMC). More preferably, the host cell is a T cell. 
     For purposes herein, the T cell can be any T cell, such as a cultured T cell, e.g., a primary T cell, or a T cell from a cultured T cell line, e.g., Jurkat, SupT1, etc., or a T cell obtained from a mammal. If obtained from a mammal, the T cell can be obtained from numerous sources, including but not limited to blood, bone marrow, lymph node, the thymus, or other tissues or fluids. T cells can also be enriched for or purified. Preferably, the T cell is a human T cell. The T cell can be any type of T cell and can be of any developmental stage, including but not limited to, CD4 + /CD8 +  double positive T cells, CD4 +  helper T cells, e.g., Th 1  and Th 2  cells, CD4 +  T cells, CD8 +  T cells (e.g., cytotoxic T cells), tumor infiltrating lymphocytes (TILs), memory T cells (e.g., central memory T cells and effector memory T cells), naïve T cells, and the like. 
     Also provided by the invention is a population of cells comprising at least one host cell described herein. The population of cells can be a heterogeneous population comprising the host cell comprising any of the recombinant expression vectors described, in addition to at least one other cell, e.g., a host cell (e.g., a T cell), which does not comprise any of the recombinant expression vectors, or a cell other than a T cell, e.g., a B cell, a macrophage, a neutrophil, an erythrocyte, a hepatocyte, an endothelial cell, an epithelial cells, a muscle cell, a brain cell, etc. Alternatively, the population of cells can be a substantially homogeneous population, in which the population comprises mainly of host cells (e.g., consisting essentially of) comprising the recombinant expression vector. The population also can be a clonal population of cells, in which all cells of the population are clones of a single host cell comprising a recombinant expression vector, such that all cells of the population comprise the recombinant expression vector. In one embodiment of the invention, the population of cells is a clonal population comprising host cells comprising a recombinant expression vector as described herein. 
     In an embodiment of the invention, the numbers of cells in the population may be rapidly expanded. Expansion of the numbers of T cells can be accomplished by any of a number of methods as are known in the art as described in, for example, U.S. Pat. Nos. 8,034,334; 8,383,099; U.S. Patent Application Publication No. 2012/0244133; Dudley et al.,  J. Immunother.,  26:332-42 (2003); and Riddell et al.,  J. Immunol. Methods,  128:189-201 (1990). In an embodiment, expansion of the numbers of T cells is carried out by culturing the T cells with OKT3 antibody, IL-2, and feeder PBMC (e.g., irradiated allogeneic PBMC). 
     The inventive TCRs, polypeptides, proteins, nucleic acids, recombinant expression vectors, and host cells (including populations thereof), can be isolated and/or purified. The term “isolated” as used herein means having been removed from its natural environment. The term “purified” as used herein means having been increased in purity, wherein “purity” is a relative term, and not to be necessarily construed as absolute purity. For example, the purity can be at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, or can be about 100%. 
     The inventive TCRs, polypeptides, proteins, nucleic acids, recombinant expression vectors, and host cells (including populations thereof), all of which are collectively referred to as “inventive TCR materials” hereinafter, can be formulated into a composition, such as a pharmaceutical composition. In this regard, the invention provides a pharmaceutical composition comprising any of the TCRs, polypeptides, proteins, nucleic acids, expression vectors, and host cells (including populations thereof), described herein, and a pharmaceutically acceptable carrier. The inventive pharmaceutical compositions containing any of the inventive TCR materials can comprise more than one inventive TCR material, e.g., a polypeptide and a nucleic acid, or two or more different TCRs. Alternatively, the pharmaceutical composition can comprise an inventive TCR material in combination with another pharmaceutically active agent(s) or drug(s), such as a chemotherapeutic agents, e.g., asparaginase, busulfan, carboplatin, cisplatin, daunorubicin, doxorubicin, fluorouracil, gemcitabine, hydroxyurea, methotrexate, paclitaxel, rituximab, vinblastine, vincristine, etc. 
     Preferably, the carrier is a pharmaceutically acceptable carrier. With respect to pharmaceutical compositions, the carrier can be any of those conventionally used for the particular inventive TCR material under consideration. Methods for preparing administrable compositions are known or apparent to those skilled in the art and are described in more detail in, for example,  Remington: The Science and Practice of Pharmacy,  22 nd  Ed., Pharmaceutical Press (2012). It is preferred that the pharmaceutically acceptable carrier be one which has no detrimental side effects or toxicity under the conditions of use. 
     The choice of carrier will be determined in part by the particular inventive TCR material, as well as by the particular method used to administer the inventive TCR material. Accordingly, there are a variety of suitable formulations of the pharmaceutical composition of the invention. Suitable formulations may include any of those for parenteral, subcutaneous, intravenous, intramuscular, intraarterial, intrathecal, intratumoral, or interperitoneal administration. More than one route can be used to administer the inventive TCR materials, and in certain instances, a particular route can provide a more immediate and more effective response than another route. 
     Preferably, the inventive TCR material is administered by injection, e.g., intravenously. When the inventive TCR material is a host cell expressing the inventive TCR, the pharmaceutically acceptable carrier for the cells for injection may include any isotonic carrier such as, for example, normal saline (about 0.90% w/v of NaCl in water, about 300 mOsm/L NaCl in water, or about 9.0 g NaCl per liter of water), NORMOSOL® electrolyte solution (Abbott, Chicago, Ill.), PLASMA-LYTE A (Baxter, Deerfield, Ill.), about 5% dextrose in water, or Ringer&#39;s lactate. In an embodiment, the pharmaceutically acceptable carrier is supplemented with human serum albumen. 
     For purposes of the invention, the amount or dose (e.g., numbers of cells when the inventive TCR material is one or more cells) of the inventive TCR material administered should be sufficient to effect, e.g., a therapeutic or prophylactic response, in the subject or animal over a reasonable time frame. For example, the dose of the inventive TCR material should be sufficient to bind to a cancer antigen (e.g., mutated p53), or detect, treat or prevent cancer in a period of from about 2 hours or longer, e.g., 12 to 24 or more hours, from the time of administration. In certain embodiments, the time period could be even longer. The dose will be determined by the efficacy of the particular inventive TCR material and the condition of the animal (e.g., human), as well as the body weight of the animal (e.g., human) to be treated. 
     Many assays for determining an administered dose are known in the art. For purposes of the invention, an assay, which comprises comparing the extent to which target cells are lysed or IFN-γ is secreted by T cells expressing the inventive TCR, polypeptide, or protein upon administration of a given dose of such T cells to a mammal among a set of mammals of which each is given a different dose of the T cells, could be used to determine a starting dose to be administered to a mammal. The extent to which target cells are lysed or IFN-γ is secreted upon administration of a certain dose can be assayed by methods known in the art. 
     The dose of the inventive TCR material also will be determined by the existence, nature and extent of any adverse side effects that might accompany the administration of a particular inventive TCR material. Typically, the attending physician will decide the dosage of the inventive TCR material with which to treat each individual patient, taking into consideration a variety of factors, such as age, body weight, general health, diet, sex, inventive TCR material to be administered, route of administration, and the severity of the cancer being treated. In an embodiment in which the inventive TCR material is a population of cells, the number of cells administered per infusion may vary, e.g., from about 1×10 6  to about 1×10 12  cells or more. In certain embodiments, fewer than 1×10 6  cells may be administered. 
     One of ordinary skill in the art will readily appreciate that the inventive TCR materials of the invention can be modified in any number of ways, such that the therapeutic or prophylactic efficacy of the inventive TCR materials is increased through the modification. For instance, the inventive TCR materials can be conjugated either directly or indirectly through a bridge to a chemotherapeutic agent. The practice of conjugating compounds to a chemotherapeutic agent is known in the art. One of ordinary skill in the art recognizes that sites on the inventive TCR materials, which are not necessary for the function of the inventive TCR materials, are ideal sites for attaching a bridge and/or a chemotherapeutic agent, provided that the bridge and/or chemotherapeutic agent, once attached to the inventive TCR materials, do(es) not interfere with the function of the inventive TCR materials, i.e., the ability to bind to mutated p53 or to detect, treat, or prevent cancer. 
     It is contemplated that the inventive pharmaceutical compositions, TCRs, polypeptides, proteins, nucleic acids, recombinant expression vectors, host cells, or populations of cells can be used in methods of treating or preventing cancer. Without being bound to a particular theory, the inventive TCRs are believed to bind specifically to mutated p53, such that the TCR (or related inventive polypeptide or protein), when expressed by a cell, is able to mediate an immune response against a target cell expressing mutated p53. In this regard, an embodiment of the invention provides a method of treating or preventing cancer in a mammal, comprising administering to the mammal any of the pharmaceutical compositions, TCRs, polypeptides, or proteins described herein, any nucleic acid or recombinant expression vector comprising a nucleotide sequence encoding any of the TCRs, polypeptides, proteins described herein, or any host cell or population of cells comprising a recombinant vector which encodes any of the TCRs, polypeptides, or proteins described herein, in an amount effective to treat or prevent cancer in the mammal. 
     An embodiment of the invention provides any of the pharmaceutical compositions, TCRs, polypeptides, or proteins described herein, any nucleic acid or recombinant expression vector comprising a nucleotide sequence encoding any of the TCRs, polypeptides, proteins described herein, or any host cell or population of cells comprising a recombinant vector which encodes any of the TCRs, polypeptides, or proteins described herein, for use in the treatment or prevention of cancer in a mammal. 
     The terms “treat,” and “prevent” as well as words stemming therefrom, as used herein, do not necessarily imply 100% or complete treatment or prevention. Rather, there are varying degrees of treatment or prevention of which one of ordinary skill in the art recognizes as having a potential benefit or therapeutic effect. In this respect, the inventive methods can provide any amount of any level of treatment or prevention of cancer in a mammal. Furthermore, the treatment or prevention provided by the inventive method can include treatment or prevention of one or more conditions or symptoms of the cancer being treated or prevented. For example, treatment or prevention can include promoting the regression of a tumor. Also, for purposes herein, “prevention” can encompass delaying the onset of the cancer, or a symptom or condition thereof. Alternatively or additionally, “prevention” may encompass preventing or delaying the recurrence of cancer, or a symptom or condition thereof. 
     Also provided by an embodiment of the invention is a method of detecting the presence of cancer in a mammal. The method comprises (i) contacting a sample comprising one or more cells from the mammal with any of the inventive TCRs, polypeptides, proteins, nucleic acids, recombinant expression vectors, host cells, populations of cells, or pharmaceutical compositions described herein, thereby forming a complex, and detecting the complex, wherein detection of the complex is indicative of the presence of cancer in the mammal. 
     With respect to the inventive method of detecting cancer in a mammal, the sample of cells can be a sample comprising whole cells, lysates thereof, or a fraction of the whole cell lysates, e.g., a nuclear or cytoplasmic fraction, a whole protein fraction, or a nucleic acid fraction. 
     For purposes of the inventive detecting method, the contacting can take place in vitro or in vivo with respect to the mammal. Preferably, the contacting is in vitro. 
     Also, detection of the complex can occur through any number of ways known in the art. For instance, the inventive TCRs, polypeptides, proteins, nucleic acids, recombinant expression vectors, host cells, or populations of cells, described herein, can be labeled with a detectable label such as, for instance, a radioisotope, a fluorophore (e.g., fluorescein isothiocyanate (FITC), phycoerythrin (PE)), an enzyme (e.g., alkaline phosphatase, horseradish peroxidase), and element particles (e.g., gold particles). 
     For purposes of the inventive methods, wherein host cells or populations of cells are administered, the cells can be cells that are allogeneic or autologous to the mammal. Preferably, the cells are autologous to the mammal. 
     With respect to the inventive methods, the cancer can be any cancer, including any of acute lymphocytic cancer, acute myeloid leukemia, alveolar rhabdomyosarcoma, bone cancer, brain cancer, breast cancer, cancer of the anus, anal canal, or anorectum, cancer of the eye, cancer of the intrahepatic bile duct, cancer of the joints, cancer of the neck, gallbladder, or pleura, cancer of the nose, nasal cavity, or middle ear, cancer of the oral cavity, cancer of the vagina, cancer of the vulva, chronic lymphocytic leukemia, chronic myeloid cancer, colon cancer, colocrectal cancer, endometrial cancer, esophageal cancer, uterine cervical cancer, gastrointestinal carcinoid tumor, glioma, Hodgkin lymphoma, hypopharynx cancer, kidney cancer, larynx cancer, liver cancer, lung cancer, malignant mesothelioma, melanoma, multiple myeloma, nasopharynx cancer, non-Hodgkin lymphoma, cancer of the oropharynx, ovarian cancer, cancer of the penis, pancreatic cancer, peritoneum, omentum, and mesentery cancer, pharynx cancer, prostate cancer, rectal cancer, renal cancer, skin cancer, small intestine cancer, soft tissue cancer, stomach cancer, testicular cancer, thyroid cancer, cancer of the uterus, ureter cancer, and urinary bladder cancer. In a preferred embodiment, the cancer is a cancer which expresses mutated p53. The cancer may express p53 with a mutation at any one or more of positions 175, 220, 245, 248, 249, 273, and 282 of SEQ ID NO: 1. The cancer may express p53 with any one or more of the following human p53 mutations: R175H, Y220C, G245D, G245S, R248L, R248Q, R248W, R249S, R273H, R273C, R273L, and R282W. Preferably, the cancer is an epithelial cancer or cholangiocarcinoma, melanoma, colon cancer, rectal cancer, ovarian cancer, endometrial cancer, non-small cell lung cancer (NSCLC), glioblastoma, uterine cervical cancer, head and neck cancer, breast cancer, pancreatic cancer, or bladder cancer. 
     The mammal referred to in the inventive methods can be any mammal. As used herein, the term “mammal” refers to any mammal, including, but not limited to, mammals of the order Rodentia, such as mice and hamsters, and mammals of the order Logomorpha, such as rabbits. It is preferred that the mammals are from the order Carnivora, including Felines (cats) and Canines (dogs). It is more preferred that the mammals are from the order Artiodactyla, including Bovines (cows) and Swines (pigs) or of the order Perssodactyla, including Equines (horses). It is most preferred that the mammals are of the order Primates, Ceboids, or Simoids (monkeys) or of the order Anthropoids (humans and apes). An especially preferred mammal is the human. 
     The following examples further illustrate the invention but, of course, should not be construed as in any way limiting its scope.

     Example 1 
     This example demonstrates the isolation and specific reactivity of four anti-mutated p53 TCRs from patient 4127. 
     Experiments were carried out as described for  FIGS. 1-7, 36, and 37A-37C  for Patient 4127. The mutated p53 reactive T cells for this patient were identified by the method described in U.S. Patent Application Number 2017/0224800 (“Tran method”). The methods for isolating the individual TCRs are set forth below. 
     Autologous PBL were transduced with one of the TCRs shown in  FIG. 1  and were tested 2 weeks later. Autologous DC cells were plated at 3×10 4  cells/well and pulsed overnight with either WT p53-G245 peptide (wt) or mutated p53-G245S peptide (mut) at decreasing peptide concentrations. 3×10 4  transduced T cells were added per well and co-cultured overnight at 37° C. Supernatants were harvested for IFN-γ ELISA. The IFN-γ ELISA results are shown in  FIG. 1 . 4-1BB expression was measured by FACS gate: lymphocytes\PI(neg)CD3 + \CD3 + mTCR + \CD8(neg)CD4 + . The FACS results are shown in  FIG. 2 . 
     Autologous PBL were transduced with one of the TCRs shown in  FIG. 3  and co-cultured as described for the experiment of  FIG. 2  except that the DCs were pulsed with DMSO (peptide vehicle) or one of the 15-mer p53-G245S peptides with overlapping 14 amino acids shown in Table A. 4-1BB expression was carried out as described for  FIG. 2 . The results are shown in  FIG. 3 .

     Cos7 cells (2.5×10 4  per well) were plated on wells of flat-bottom 96 well plates. After 20 hours, cells were co-transfected with individual HLA alleles. After 20 hours, cells were pulsed with p53G245S-15-mer peptide for 3 hours at 37° C. at 10 μg/mL. After washing, T cells (10 5 ) were added to wells and co-cultured overnight (for 20 hours) at 37° C. IFN-γ secretion was measured by ELISA; prediction by NetMHCIIpan: cbs.dtu.dk/services/NetMHCIIpan/. 4-1BB expression was measured by FACS. FACS gate: lymphocytes→live (PI negative)→CD3+ (T cells)→CD4+ (4127-TIL) or CD4+mTCR+ (TCR transduced T cells). The results are shown in  FIGS. 4-5  and Table B.

     DRB3*02 is expressed by 1367 of 3719 (37%) of DRB_typed patients in the NCI HLA database and 5 of 9 (56%) endometrial and ovarian cancer patients at NCI-SB (National Cancer Institute Surgery Branch). The reported frequency of the DRB3*02 allele is very high according to the allelefrequencies.net website. For example, this website reports that the frequency of the DRB3*02 allele is 0.3447 of the USA NMDP Middle Eastern or North Coast of Africa population. 
     TIL from patient 4127 were co-cultured with allogeneic (DRB3*01:01:01 or DRB3*02:02:01) antigen presenting cells (APCs) which were (1) electroporated with tandem minigenes (TMG) composed of irrelevant, WT p53, or mutated p53 sequence or (2) pulsed with peptide vehicle (DMSO) or purified (&gt;95% by high-performance liquid chromatography (HPLC)) 25-amino acid peptides composed of WT p53-G245 sequence or mutated p53-G245S sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 6 . 
     T cells expressing the 4127-TCR1 specific to p53-G245S were co-cultured with allogeneic APCs as described for the experiment of  FIG. 6 . The results are shown in  FIG. 7 . 
     Autologous APCs were pulsed with decreasing concentrations of 25-amino acid peptides corresponding to the WT p53-G245 or mutated p53-G245S sequence. T cells transduced with the 4127-O37-TCR from patient 4127 were co-cultured overnight at 37° C. with peptide-pulsed APCs. Expression of 4-1BB was assayed by flow cytometry after gating lymphocytes→single cells→live→CD3+mTCR+. The results are shown in  FIG. 36 . 
     Cos7 cells (2.5×10 4  per well) were plated on wells of flat-bottom 96 well plates. The following day, cells were co-transfected with individual HLA alleles from patient 4127. The next day, the 25-amino acid p53-G245S peptide was pulsed on transfected Cos7 cells. Excess peptide was washed away. T cells were transduced with one of the TCRs from Patient 4127. The transduced T cells were added (2×10 4  cells/well) to the co-culture with the Cos7 cells. Co-cultures were incubated overnight at 37° C. Secretion of IFN-γ was evaluated by ELISA. Expression of 4-1BB was assayed by flow cytometry after gating lymphocytes→single cells→live→CD3+mTCR+. The results are shown in  FIGS. 37A-37C .

     TMG1 versus 4196-Rx1 TIL: Cos7 cells were transfected with plasmids for TMG1 and HLA allele. Cells were co-cultured with 4196 Rx1 TIL infusion bag for 20 hours (h). The results are shown in  FIG. 8A . 
     P53-R175H minimal peptide versus 4196-Rx1 TIL: Day 4 autologous DCs were pulsed with either candidate minimal epitope (HMTEVVRHC (SEQ ID NO: 530) or (SQHMTEVVRH (SEQ ID NO: 531)) for 2 h. Cells were washed and co-cultured with 4196 Rx1 TIL infusion bag for 20 h. The results are shown in  FIG. 8B . 
     A*02:01-restricted TP53 tetramer can be used to isolate TP53-reactive cells from the TIL infusion bag: Isolation of TP53-reactive cells using 4-1BB+ sort following co-culture with TP53 peptide was technically limited. To isolate TP53-reactive cells, an A*02:01-TP53 tetramer was generated. An irrelevant tetramer (A*02:01-gp100) was generated as a control. A FACS analysis was carried out gated on live, CD3+, CD8+ cells. For the A*02:01-TP53 tetramer, 14.9% p53 tetramer+ cells were detected. For the A*02:01-gp100 tetramer, 0.7% p53 tetramer+ cells were detected. 
     Isolation and characterization of TP53-reactive cells: The strategy for the isolation and characterization of TP53-reactive cells was as follows: (1) sort for tetramer-positive cells using FACS as described above. (2) Carry out single cell PCR. (3) Carry out Vβ seep sequencing. 
     Several candidate clones were identified for the TP53 TCR using single cell PCR, as shown in Table D. TCR-1a and TCR-1b were alternative candidate clones.

     Plasmids encoding candidate TCRs were cloned with MSGV1 vectors. Retroviral transduction was used to introduce TCR into donor lymphocytes. 
     HPLC grade minimal epitope was pulsed on day 4 on A*02:01 DCs for 2 h. DCs were co-cultured with TCR-transduced cells for 20 h. The results are shown in  FIGS. 9A-9D . Three different A*02:01 restricted TP53 receptors were identified. 
     T2 cells were thawed and rested for 24 hours, then pulsed with decreasing concentrations of HPLC minimal epitope for 2 h. Cells were then washed and co-cultured with TP53 TCR-transduced cells for 17 h. The results are shown in  FIGS. 10A-10B . 
     The following parental tumor cell lines were transduced with HLA-A*02:01: Colon line—LS123 (ATCC CCL-255) with R175H but unknown HLA-A2 status. Leukemia line: CCRF-CEM (ATCC CRM-CCL-119, leukemia) with R175H but unknown HLA-A2 status. Breast line: AU-565 (ATCC CRL-2351, breast adenocarcinoma) with R175H but unknown HLA-A2 status. Melanoma cell line: MEL624; endogenous expression of HLA-A2 and wt R175. 
     Target transduced tumor cells were harvested and plated on the morning of co-culture (1×10 5  cells/well). R175H minimal epitope was pulsed onto target cells (HPLC, 5 μg/mL) for 2 h. Cells were washed twice and co-cultured with 2×10 4  TP53 TCR-transduced cells for 20 h (patient 4196). IFN-γ ELISPOT was used for the readout of response. The results are shown in  FIG. 11 . Additional experimental data regarding target cell HLA-A2 and TP53 expression and the reactivity of the TCRs of this Example is provided in Example 15.

     Example 3 
     This example demonstrates the isolation of eleven anti-mutated p53 TCRs from patient 4238. 
     Experiments were carried out as described for  FIGS. 12-15  for Patient 4238. 
     TIL fragments (F1-F24, n=24) from patient 4238 were co-cultured with autologous APCs electroporated with TMG composed of the irrelevant or mutated p53 sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 12 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 14 . 
     TIL fragments (F1-F24, n=24) from patient 4238 were co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptide composed of the mutated p53-R248Q sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 13 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 15 . 
     TIL fragments F10, F11 and F17 were sources of TCRs after sorting CD8+41BB+ T cells. 
     The sequence of TCR 4238-F10-TCR1, which was isolated from Patient 4238, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 207), the second underlined region is the CDR2alpha (SEQ ID NO: 208), the third underlined region is the CDR3alpha (SEQ ID NO: 209), the fourth underlined region is the CDR1beta (SEQ ID NO: 210), the fifth underlined region is the CDR2beta (SEQ ID NO: 211), and the sixth underlined region is the CDR3beta (SEQ ID NO: 212). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 213) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 214) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 215) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 216) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     Example 4 
     This example demonstrates the isolation of two anti-mutated p53 TCRs from patient 4253. 
     An experiment was carried out as described for  FIG. 16  for Patient 4253. 
     TIL fragments (F1-F24; n=24) from patient 4253 were co-cultured with autologous APCs (1) pulsed with peptide vehicle (DMSO), (2) pulsed with purified (&gt;95% by HPLC) 25-amino acid peptides composed of mutated p53-R248W sequence, (3) electroporated with an irrelevant TMG or (4) electroporated with p53-mut-TMG containing the mutated p53-R248W sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated by ELISPOT. The results are shown in  FIG. 16 . F15 was selected for sorting for TCRs because it was reactive to both p53-mut-TMG and p53-R248W long peptide. 
     The sequence of TCR 4253-TIL-TCR1, which was isolated from Patient 4253, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 187), the second underlined region is the CDR2alpha (SEQ ID NO: 188), the third underlined region is the CDR3alpha (SEQ ID NO: 189), the fourth underlined region is the CDR1beta (SEQ ID NO: 190), the fifth underlined region is the CDR2beta (SEQ ID NO: 191), and the sixth underlined region is the CDR3beta (SEQ ID NO: 192). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 193) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 194) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 195) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 196) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     Example 5 
     This example demonstrates the identification of anti-mutated p53 T cells in Patient 4273 by co-culturing autologous APCs induced to express mutated p53 within autologous T cells (“p53 hotspot mutation universal screening”). This example also demonstrates the isolation of two anti-mutated p53 TCRs from patient 4273. 
     Experiments were carried out as described for  FIGS. 17-20 and 56-60  for Patient 4273. 
     TIL fragments (F1-F24, n=24) from patient 4273 were co-cultured with autologous APCs electroporated with TMG composed of irrelevant, WT p53 or mutated p53 sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 17 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 18 . 
     TIL fragments (F1-F24, n=24) from patient 4273 were co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of WT p53-R248 sequence or mutated p53-R248W sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 19 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 20 . 
     For patient 4273, F15 was the most reactive fragment and the responses by F15 to the LP and TMG were comparable and primarily by CD4 T cells. So 4273-F15 was co-cultured with APCs pulsed with the R248W LP, and the following day CD4+41BB+ T cells were sorted as single cells into to the wells of a 96 well PCR plate at one cell per well. The PCR plate has an RT-PCR solution in each well, which amplifies the TCR alpha and beta CDR3 regions in the same solution. The wells of the plate are then split into two 96 well PCR plates and a second PCR round is performed to amplify either the CDR3 alpha or the CDR3 beta as separate reactions. The PCR products from each well (total of 192 PCR products mapped to each well—alpha or beta) are sequenced by Sanger sequencing. The nucleotide sequence is inputted into IMGT/V-QUEST (imgt.org/IMGT_vquest/vquest?livret=0&amp;Option=humanTcR), IgBlast (ncbi.nlm.nih.gov/igblast/igblast.cgi?CMD=Web&amp;SEARCH_TYPE=TCR&amp;LINK_LOC=igtab) and translated by Expasy (web.expasy.org/translate/). The variable family is determined and fused to the CDR3 and junction (J or DJ) from the translated sequence. The variable sequence is fused to the murine constant sequence and the reconstructed TCRalpha and TCRbeta are linked by furin-felxible-P2A (RAKR-SGSG-ATNFSLLKQAGDVEENPGP) (SEQ ID NO: 26). Then the sequence is synthesized into DNA de novo and cloned into an expression vector (gamma-retrovirus or SLEEPING BEAUTY (SB) transposon (University of Minnesota, Minneapolis, Minn.)). T cells are then made to express the TCR using the standard viral transduction or non-viral transposition protocols and T cells expressing murinized TCRs (as detected by mouse TCR beta constant chain) are tested against the putative peptide. 
     Autologous APCs were transfected with TMG encoding irrelevant mutations, WT p53 sequences or mutated p53 sequences including p53-R248W. Media alone and PMA and Ionomycin were negative and positive controls, respectively. TIL from patient 4273 (fragment cultures 8 and 15) were co-cultured overnight at 37° C. with TMG transfected APCs. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 56 . 
     Autologous APCs were pulsed with 25 amino acid peptides corresponding to the WT or mutated p53-R248W neoepitope for 2 hours at 37° C. TIL from patient 4273 (fragment culture 15) with specificity to p53-R248W were co-cultured overnight at 37° C. with peptide-pulsed APCs. DMSO was peptide vehicle. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 57 . 
     Autologous APCs were pulsed with 15 amino acid peptides from the p53-R248W neoepitope overlapping 14 amino acids. TIL from patient 4273 (fragment culture 15) with specificity to p53-R248W were co-cultured overnight at 37° C. with peptide-pulsed APCs. DMSO was peptide vehicle, media alone (T cells only) and PMA and ionomycin were controls. The 25 amino acid peptides (wt p53-R248 and mutated p53-R248W) were additional controls for the 15 amino acid peptides. Expression of 4-1 BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative) 4 CD3+ (T cells)→CD4+CD8−. The results are shown in  FIG. 58 . 
     Cos7 cells (2.5×10 4  per well) were plated on wells of flat-bottom 96 well plates. The following day, cells were co-transfected with individual HLA alleles from patient 4273 and either wild type or mutated TP53 TMG with or without the p53-R248W neoantigen, respectively. The following day, TIL with specificity to p53-R248W from Patient 4273 (fragment culture 15) were co-cultured with transfected Cos7 cells overnight at 37° C. Secretion of IFN-γ was evaluated by ELISA. The results are shown in  FIG. 59 . 
     T cells expressing mock (no TCR) or 4273-TCR1a2 were co-cultured with autologous APCs which were pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25 amino acid peptides composed of wild type p53-R248 sequence or mutated p53-R248W sequences. Media alone and PMA and lonomycin were negative and positive controls, respectively. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated by ELISPOT. The results are shown in  FIG. 60 .

     The statistics for the TCRs of Patient 4273 are set forth in Table 19 below. In Table 19, 96 total wells sorted with 41BB+ T cells after co-culture with mutated p53 protein (TMG or peptide). 77 wells had productive pairs (meaning had (1) a sequence and (2) no stop codons in the sequence) for a pairing frequency of 80.2%. 43 of those pairs were the CDR3A/CDR3B combination to make 4273-TP53-R248W-TCR1a1 (55.8% of the productive pairs). 30 of those pairs were the CDR3A/CDR3B combination to make 4273-TP53-R248W-TCR1a2 (39% of the productive pairs). Overall, the CDR3A and CDR3B for 4273-TP53-R248W-TCR1a1 were found 50 and 83 times, respectively, out of 96 wells. Overall, the CDR3A and CDR3B for 4273-TP53-R248W-TCR1a2 were found 33 and 83 times, respectively, out of 96 wells.

     Example 6 
     This example demonstrates the identification of anti-mutated p53 T cells in Patient 4149. This example also demonstrates the isolation and specific reactivity of one anti-mutated p53 TCR from patient 4149. 
     Experiments were carried out as described for  FIGS. 21-24  for Patient 4149. The TCR was found using the Tran method. The TCR was then used to validate the “p53 hotspot mutation universal screening” method. 
     A TCR (4149-TCRa2b1 or 4149-TCRa2b2) was transposed into autologous PBL from patient 4149 and co-cultured with autologous APCs which were (1) electroporated with TMG composed of irrelevant, WT p53, or mutated p53 sequence or (2) pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of WT p53-Y220 sequence or mutated p53-Y220C sequence. Combination of PMA and ionomycin was positive control. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 21 . Expression of 4-1 BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells)→CD4+ mTCR+ (TCR transposed T cells). The results are shown in  FIG. 22 .

     Cos7 cells (2.5×10 4  per well) were plated on wells of flat-bottom 96 well plates. After 20 hours, cells were co-transfected with individual HLA alleles with or without TMGs. After 20 hours, autologous DC cells were transfected with TMG in parallel. All HLA Class-II alleles were co-transfected into one set of wells with or without TMG. Cells not transfected with TMG were pulsed with p53-Y220C 15-mer peptide for 2-3 hours at 37° C. at 10 μg/mL. After washing, 4149-TCRa2b2-transposed T cells (10 5 ) at day+14 of second REP were added to wells and co-cultured overnight at 37° C. IFN-γ secretion was measured by ELISA. The results are shown in  FIG. 24 .

     DRB3*02 expression was detected in 1367 of 3719 (37%) of DRB_typed patients in the NCI HLA database and in 5 of 9 (56%) endometrial and ovarian cancer patients at NCI-SB. The reported frequency of the DRB3*02 allele is very high, as described in Example 1. 
     The sequence of TCR 4149TCRa2b2, which was isolated from Patient 4149, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 57), the second underlined region is the CDR2alpha (SEQ ID NO: 58), the third underlined region is the CDR3alpha (SEQ ID NO: 59), the fourth underlined region is the CDR1beta (SEQ ID NO: 60), the fifth underlined region is the CDR2beta (SEQ ID NO: 61), and the sixth underlined region is the CDR3beta (SEQ ID NO: 62). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 63) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 64) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 65) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 66) includes the sequence starting immediately after the linker and ending with the carboxyl terminus. 
     Cancer reactive T cells were identified using the screening method set forth below. The p53 reactive cells for this patient were identified by the Transcreening method as described in U.S. Application No. 2017/0224800. 
     TCR name: 4149TCRa2b2
 
Recognition of p53 mutation: Y220C
 
Screening method: Used to validate the p53 “hotspot” mutation universal screening
 
Co-culture to identify TCR: Co-culture 4149-F11 TIL fragment with p53-Y220C long peptide, sorted CD4+41BB+ T cells
 
Method to identify TCR: Frequency pairing. CD4+41BB+ sorted T cells were expanded in REP (rapid expansion protocol) and the resulting T cell culture was subjected to TCRAD (alpha) and TCRB (beta) deep sequencing by Adaptive Biotechnologies. The top two TCR alphas were paired with the top two TCR betas in a matrix of 4 total TCRs. The second TCR alpha and second TCR beta was the reactive TCR hence TCRa2b2 nomenclature.

     Example 7 
     This example demonstrates the identification of anti-mutated p53 T cells in Patient 4213 by co-culturing autologous APCs induced to express mutated p53 within autologous T cells (“p53 hotspot mutation universal screening”). This example also demonstrates the isolation of twelve anti-mutated p53 TCRs from patient 4213. 
     Experiments were carried out as described for  FIGS. 25-26  for Patient 4213. 
     TIL fragments (F2 and F24) from patient 4213 were co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of the mutated p53-R248Q sequence. Co-cultures were performed overnight at 37° C. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 25 . CD8+4-1BB+ T cells were sorted into wells of 96 wells plates. TCRs were identified using single-cell RT-PCR. 
     CD4+ T cells came from patient 4213&#39;s peripheral blood lymphocytes. The CD4+ T cell culture was co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of the mutated p53-R248Q sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated by ELISPOT. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative) 4 CD3+ (T cells). The results are shown in  FIG. 26 . CD4+41BB+ T cells were sorted into wells of 96 wells plates. TCRs were identified using single-cell RT-PCR. 
     The sequence of 4213-F2-TCR1, which was isolated from Patient 4213, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 317), the second underlined region is the CDR2alpha (SEQ ID NO: 318), the third underlined region is the CDR3alpha (SEQ ID NO: 319), the fourth underlined region is the CDR1beta (SEQ ID NO: 320), the fifth underlined region is the CDR2beta (SEQ ID NO: 321), and the sixth underlined region is the CDR3beta (SEQ ID NO: 322). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 323) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 324) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 325) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 326) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     Example 8 
     This example demonstrates the identification of anti-mutated p53 T cells in Patient 4268 by co-culturing autologous APCs induced to express mutated p53 within autologous T cells (“p53 hotspot mutation universal screening”). This example also demonstrates the isolation of five anti-mutated p53 TCRs from patient 4268. 
     Experiments were carried out as described for  FIGS. 27-30  for Patient 4268. 
     TIL fragments (F1-F24, n=24) from patient 4268 were co-cultured with autologous APCs electroporated with TMG composed of irrelevant, WT p53, or mutated p53 sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 27 . 
     TIL fragments (F1-F24, n=24) from patient 4268 were co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of WT p53-R248 sequence or mutated p53-R248Q sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 28 . 
     TIL fragments (F1-F24, n=24) from patient 4268 were co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of wt p53-R248 sequence or mutated p53-R248Q sequence. Co-cultures were performed overnight at 37° C. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 29 . TIL fragments F18 and F19 were sources of TCRs after sorting CD4+41BB+ T cells.

     Example 9 
     This example demonstrates the identification of anti-mutated p53 T cells in Patient 4266 by co-culturing autologous APCs induced to express mutated p53 within autologous T cells (“p53 hotspot mutation universal screening”). This example also demonstrates the isolation of four anti-mutated p53 TCRs from patient 4266. 
     Experiments were carried out as described for  FIGS. 31-34 and 53-55  for Patient 4266. 
     TIL fragments (F1-F24, n=24) from patient 4266 were co-cultured with autologous APCs electroporated with TMG composed of irrelevant, WT p53, or mutated p53 sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 31 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 32 . 
     TIL fragments (F1-F24, n=24) from patient 4266 were co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of WT p53-R248 sequence or mutated p53-R248W sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 33 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 34 . 
     Cos7 cells (2.5×10 4  per well) were plated on wells of flat-bottom 96 well plates. The following day, cells were co-transfected with individual HLA alleles from patient 4266. The next day cells were pulsed with no peptide, DMSO, wild type p53-R248 peptide SSCMGGMNRR (SEQ ID NO: 590) or mutated p53-R248W peptide SSCMGGMNWR (SEQ ID NO: 591) for 2 hours at 37° C. at 1 μg/mL. TIL cultures from patient 4266 (10 5 ) were added to wells and co-cultured overnight at 37° C. Expression of 4-1 BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells) 4 CD4−CD8+. The results are shown in  FIG. 53 . 
     T cells expressing mock (no TCR), 4266-TCR1, 4266-TCR2, 4266-TCR3 or 4266-TCR4 with putative specificity to p53-R248W identified from 4266-TIL were co-cultured with autologous APCs which were pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25 amino acid peptides composed of WT p53-R248 sequence or mutated p53-R248W sequences. Media alone and PMA and lonomycin were negative and positive controls, respectively. Co-cultures were performed overnight at 37° C. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+(T cells)→CD4−CD8+. The results are shown in  FIG. 54 . 
     A tumor cell (TC) line was established from a xenografted tumor fragment resected from Patient 4266 then serially passaged through immunocompromised mice (TC #4266). The TC #4266 was co-cultured with T cells (10 5 ) expressing mock (no TCR) or p53-R248W-specific TCRs (4266-TCR2, 4266-TCR3 or 4266-TCR4) overnight at 37° C. The TC #4266 cells were either incubated with nothing, W6/32 pan-HLA Class-1 specific blocking antibody, IVA12 pan-HLA Class-II specific blocking antibody or mutated p53-R248W peptide SSCMGGMNWR (SEQ ID NO: 591) for 2 hours at 37° C. The antibodies were kept in the co-culture at 5 μg/mL final concentration. The peptide was incubated at 1 g/mL and excess peptide was washed after incubation. Media alone (no TC) and PMA and lonomycin were negative and positive controls, respectively. Expression of 4-1 BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells)→CD4−CD8+. The results are shown in  FIG. 55 . 
     The sequence of 4266-TCR1, which was isolated from Patient 4266, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 97), the second underlined region is the CDR2alpha (SEQ ID NO: 98), the third underlined region is the CDR3alpha (SEQ ID NO: 99), the fourth underlined region is the CDR1beta (SEQ ID NO: 100), the fifth underlined region is the CDR2beta (SEQ ID NO: 101), and the sixth underlined region is the CDR3beta (SEQ ID NO: 102). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 103) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 104) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 105) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 106) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     The sequence of 4266-TCR4, which was isolated from Patient 4266, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 127), the second underlined region is the CDR2alpha (SEQ ID NO: 128), the third underlined region is the CDR3alpha (SEQ ID NO: 129), the fourth underlined region is the CDR1beta (SEQ ID NO: 130), the fifth underlined region is the CDR2beta (SEQ ID NO: 131), and the sixth underlined region is the CDR3beta (SEQ ID NO: 132). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 133) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 134) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 135) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 136) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     Example 12 
     This example demonstrates the isolation and specific reactivity of a TCR from patient 4141. 
     Autologous APCs were transfected with TMG encoding irrelevant mutations, WT p53 sequence, or mutated p53 sequence including R175H. Media alone and PMA and ionomycin were negative and positive controls, respectively. The following day, TIL from patient 4141 (fragment culture 12) were co-cultured overnight at 37° C. with TMG-transfected APCs. Secretion of IFN-γ was evaluated by ELISPOT. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+(T cells)→CD4−CD8+. The results are shown in  FIG. 38 . 
     Cos7 cells (2.5×10 4  per well) were plated on wells of flat-bottom 96 well plates. The following day, cells were co-transfected with individual HLA alleles from patient 4141 and either no extra gene, WT TP53 TMG, or mutated TP53 TMG containing the p53-R175H sequence. TIL with specificity to p53-R175H from Patient 4141 (fragment culture 12) were co-cultured the following day with transfected Cos7 cells and were incubated overnight at 37° C. Secretion of IFN-γ was evaluated by ELISPOT. The results are shown in  FIG. 39 . 
     T cells expressing mock (no TCR) or 4141-TCR1a2 were co-cultured with T2 tumor cells (expressing HLA-A*02:01). T2 cells were pulsed for 2 hours at 37° C. with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) peptides composed of WT p53-R175 peptide HMTEVVRRC (SEQ ID NO: 532) or mutated p53-R175H peptide HMTEVVRHC (SEQ ID NO: 530). Media alone and PMA and lonomycin were negative and positive controls, respectively. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated by ELISA. The results are shown in  FIG. 40 . 
     T cells expressing 4141-TCR1a2 were co-cultured overnight at 37° C. with Saos2 cells (p53-NULL and HLA-A*02:01+), which were either unmanipulated or made to overexpress full length p53-R175H protein. Inhibitors of secretion (monensin and brefeldin A) were added to co-cultures to trap cytokines within T cells. After 6 hours of co-culture, cells were fixed and permeabilized then stained for IL-2, CD107a, IFN-γ and tumor necrosis factor-alpha (TNFα). Flow cytometry was used to analyze co-cultures based on a lymphocyte gate. The results are shown in  FIG. 41 . 
     The sequence of TCR 4141-TCR1a2, which was isolated from Patient 4141, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 467), the second underlined region is the CDR2alpha (SEQ ID NO: 468), the third underlined region is the CDR3alpha (SEQ ID NO: 469), the fourth underlined region is the CDR1beta (SEQ ID NO: 470), the fifth underlined region is the CDR2beta (SEQ ID NO: 471), and the sixth underlined region is the CDR3beta (SEQ ID NO: 472). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 473) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 474) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 475) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 476) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     A tumor cell (TC) line was established from a xenografted tumor fragment resected from Patient 4259 and then serially passaged through immunocompromised mice (TC #4259). TC #4259 was co-cultured with T cells (10 5 ) expressing mock (no TCR) or p53-Y220C-specific TCR (4259-F6-TCR) overnight at 37° C. The TC #4259 cells were either incubated with nothing, W6/32 pan-HLA Class-1 specific blocking antibody, IVA12 pan-HLA Class-II specific blocking antibody or mutated p53-Y220C peptide RNTFRHSVVVPCE (SEQ ID NO: 534) for 2 hours at 37° C. The antibodies were kept in the co-culture at 5 μg/mL final concentration. The peptide was incubated at 10 μg/mL and excess peptide was washed after incubation. Media alone (no TC) and PMA and Ionomycin were negative and positive controls, respectively. Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 46 . 
     The sequence of TCR 4259-F6-TCR, which was isolated from Patient 4259, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 477), the second underlined region is the CDR2alpha (SEQ ID NO: 478), the third underlined region is the CDR3alpha (SEQ ID NO: 479), the fourth underlined region is the CDR1beta (SEQ ID NO: 480), the fifth underlined region is the CDR2beta (SEQ ID NO: 481), and the sixth underlined region is the CDR3beta (SEQ ID NO: 482). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 483) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 484) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 485) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 486) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     This example demonstrates the isolation and specific reactivity of a TCR from patient 4285. 
     TIL fragments (F1-F22 and F24, n=23) from patient 4285 were co-cultured with autologous APCs electroporated with TMG composed of irrelevant, WT p53, or mutated p53 sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 47 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 49 . 
     TIL fragments (F1-F22 and F24, n=23) from patient 4285 were co-cultured with autologous APCs pulsed with peptide vehicle (DMSO) or purified (&gt;95% by HPLC) 25-amino acid peptides composed of WT p53-R175 sequence or mutated p53-R175H sequence. Co-cultures were performed overnight at 37° C. Secretion of IFN-γ was evaluated using ELISPOT assay. The results are shown in  FIG. 48 . Expression of 4-1BB was evaluated by flow cytometry after gating for lymphocytes→living cells (PI negative)→CD3+ (T cells). The results are shown in  FIG. 50 . TIL fragment F6 was the source of 4285-TCR 1 after sorting CD4+41BB+ T cells. 
     Autologous APCs were pulsed with 15-amino acid peptides from the p53-R175H sequence (amino acid substitution underlined in Table 45) overlapping 14 amino acids. TIL from patient 4285 (fragment cultures 10, 6 and 9) with specificity to p53-R175H were co-cultured overnight at 37° C. with peptide-pulsed APCs. DMSO was peptide vehicle. Secretion of IFN-7 was evaluated using ELISPOT assay. The results are shown in Table 47.

     Cos7 cells (2.5×10 4  per well) were plated on wells of flat-bottom 96 well plates. The following day, cells were co-transfected with individual HLA alleles from patient 4285. The next day cells were pulsed with DMSO or mutated p53-R175H peptide YKQSQHMTEVVRHCPHHERCSDSDG (SEQ ID NO: 2) for 2 hours at 37° C. at 10 μg/mL. Selected TIL fragment cultures with specificity to p53-R175H from Patient 4285 (4285-F6, 4285-F9 and 4285-F10) were co-cultured with transfected Cos7 cells overnight at 37° C. Expression of 4-1BB was assayed by flow cytometry after gating lymphocytes→live→CD3+ (T cells) 4 CD8−CD4+. The results are shown in  FIG. 51 . 
     Autologous APCs were pulsed with decreasing concentrations of 25- or 15-amino acid peptides corresponding to the WT or mutated p53-R175H sequence for 2 hours at 37° C. T cells transposed with 4285-TCR1 from patient 4285 were co-cultured overnight at 37° C. with peptide-pulsed APCs. Expression of 4-1BB was assayed by flow cytometry after gating lymphocytes→live→CD3+ (T cells)→CD8−CD4+. The results are shown in  FIG. 52 . 
     The sequence of 4285-TCR1, which was isolated from Patient 4285, is set forth below. Starting from the amino terminus, the first underlined region is the CDR1alpha (SEQ ID NO: 487), the second underlined region is the CDR2alpha (SEQ ID NO: 488), the third underlined region is the CDR3alpha (SEQ ID NO: 489), the fourth underlined region is the CDR1beta (SEQ ID NO: 490), the fifth underlined region is the CDR2beta (SEQ ID NO: 491), and the sixth underlined region is the CDR3beta (SEQ ID NO: 492). The bold region is the linker (SEQ ID NO: 26). Starting from the amino terminus, the first italicized region is the alpha chain constant region (SEQ ID NO: 23) and the second italicized region is the beta chain constant region (SEQ ID NO: 25). The alpha chain variable region (SEQ ID NO: 493) includes the sequence starting from the amino terminus and ending immediately prior to the start of the alpha chain constant region. The beta chain variable region (SEQ ID NO: 494) includes the sequence starting immediately after the linker and ending immediately prior to the start of the beta chain constant region. The full-length alpha chain (SEQ ID NO: 495) includes the sequence starting from the amino terminus and ending immediately prior to the start of the linker. The full-length beta chain (SEQ ID NO: 496) includes the sequence starting immediately after the linker and ending with the carboxyl terminus.

     The target cells of Table 49 were co-cultured with cells that were transduced with one of the TCRs of Example 2. Mock-transduced cells (no TCR) were used as control effector cells. IFN-γ secretion (pg/mL) (Table 50) and 4-1BB expression (% 4-1BB (of mTCRβ+)) (Table 51) were measured.

     The use of the terms “a” and “an” and “the” and “at least one” and similar referents in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The use of the term “at least one” followed by a list of one or more items (for example, “at least one of A and B”) is to be construed to mean one item selected from the listed items (A or B) or any combination of two or more of the listed items (A and B), unless otherwise indicated herein or clearly contradicted by context. The terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention. 
     Preferred embodiments of this invention are described herein, including the best mode known to the inventors for carrying out the invention. Variations of those preferred embodiments may become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventors expect skilled artisans to employ such variations as appropriate, and the inventors intend for the invention to be practiced otherwise than as specifically described herein. Accordingly, this invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.
