Abstract:
:A major barrier to the design of immunotherapeutics and vaccines for cancer is the idiosyncratic nature of many tumor antigens and the possibility that T cells may be tolerant of broadly distributed antigens. We have devised an experimental strategy that exploits species differences in protein sequences to circumvent tolerance of high-affinity T cells. HLA transgenic mice were used to obtain cytotoxic T lymphocytes specific for peptides from the human p53 tumor-suppressor molecule presented in association with HLA-A2.1. Although such p53-specific cytotoxic T cells did not recognize nontransformed human cells, they were able to lyse a wide variety of human tumor cells lines, thus confirming the existence of broadly distributed determinants that may serve as targets for immunotherapy.
