Peripheral blood lymphocytes from a melanoma patient were stimulated with autologous melanoma cells in mixed lymphocyte tumor cultures (MLTC). After three restimulations, the lytic activity of the responder cells directed against the autologous melanoma cells was higher than that against K-562 and autologous Epstein-Barr virus-transformed B cell line (EBV-B… CONTINUE READING
