Abstract: Disclosed are isolated or purified T cell receptors (TCRs) having antigenic specificity for human p53R175H or human p53Y220C. 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: The present disclosure provides methods for identifying novel neoantigen-reactive T cell receptors (TCRs) by co-culturing a reporter T cell comprising a TCR expression cassette and an antigen presenting cell expressing a target neoantigen sequence and a matched human lymphocyte antigen (HLA) sequence. The present disclosure also provides novel neoantigen-reactive TCRs and the use thereof.

Abstract: Disclosed are methods of selectively expanding a number of T cells. The methods may comprise: modifying human T cells to express a TCR, wherein the TCR comprises a murine constant region; producing a population of cells comprising a number of human T cells expressing the TCR and a number of human T cells not expressing the TCR; and culturing the population of cells in the presence of (i) irradiated feeder cells, (ii) one or more cytokines, and (iii) an antibody, or an antigen-binding portion thereof, wherein the antibody has antigenic specificity for the murine constant region of the TCR, so as to selectively expand the number of T cells expressing the TCR over the number of T cells not expressing the TCR. Also disclosed are related populations of cells, pharmaceutical compositions, and methods of treating or preventing cancer.
