Abstract: Disclosed is an isolated or purified T cell receptor (TCR), wherein the TCR has antigenic specificity for a mutated human RAS amino acid sequence with a substitution of glycine at position 13 with aspartic acid. The TCRs may recognize G13D RAS presented by an HLA-DQ heterodimer. Related polypeptides and proteins, as well as related nucleic acids, recombinant expression vectors, host cells, populations of cells, and pharmaceutical compositions are also provided. Also disclosed are methods of detecting the presence of cancer in a mammal and methods of treating or preventing cancer in a mammal.

Abstract: Disclosed is an isolated or purified T cell receptor (TCR), wherein the TCR has antigenic specificity for a mutated human RAS amino acid sequence with a substitution of glycine at position 12 with valine. The TCRs may recognize G12V RAS presented by an HLA-DR heterodimer. Related polypeptides and proteins, as well as related nucleic acids, recombinant expression vectors, host cells, populations of cells, and pharmaceutical compositions are also provided. Also disclosed are methods of detecting the presence of cancer in a mammal and methods of treating or preventing cancer in a mammal.

Abstract: Disclosed are methods of obtaining a cell population enriched for T cells with a phenotype, the method comprising: (a) obtaining a bulk population of T cells from a tumor sample of a patient; (b) specifically selecting T cells with a phenotype comprising markers CD3+, CD39?, and CD69? from the bulk population; and (c) separating the cells selected in (b) from cells which lack the phenotype to obtain a cell population enriched for T cells with the phenotype. Related methods of treating or preventing cancer, methods of selecting a therapy for a cancer patient, and methods for predicting the clinical response to immunotherapy in a cancer patient are also disclosed. Isolated or purified cell population obtained according to the methods and related pharmaceutical compositions are also disclosed.

Abstract: Provided are methods of preparing an enriched population of T cells having antigenic specificity for a target antigen. The method may comprise isolating T cells from a blood sample of a patient; selecting the isolated T cells which have a gene expression profile; and separating the selected T cells from the unselected cells. The separated selected T cells provide an enriched population of T cells having antigenic specificity for the target antigen. Methods of isolating a TCR, preparing a population of cells that express a TCR, isolated TCRs, isolated populations of cells, pharmaceutical compositions, and methods of treating or preventing a condition in a mammal are also provided.
