Human tumor antigens recognized by T cells.

The ability of tumor-reactive T cells to mediate in vivo tumor regression has been demonstrated in murine tumor models and by the clinical responses to adoptive immunotherapy with tumor-infiltrating lymphocytes isolated from human melanomas. Investigations carried out in the past several years have resulted in the isolation of a number of the genes encoding antigens recognized by melanoma-reactive T cells. The ability of these products to serve as tumor regression antigens has now begun to be evaluated in clinical vaccine trials.
