In vivo depletion of CD8+ cells resulted in complete elimination of protective effects after immunization with TC-1 cells (MHC class I+) against the TC-1 tumour challenge. After immunization with TC-1/A9 or MK16 tumour cells (MHC class I-deficient) a remarkable dependence on the presence of NK1.1+ cells was observed, Cytotoxic activity induced by TC-1 cell immunization was abrogated in CD8+ cell-depleted mice and the mice showed similar percentage of IFNgamma-producing cells in CD8+, CD4+ and NK1.1+ subpopulations.. After MK16 or TC-1/A9 cell immunization, NK1.1+ displayed significant reduction of cytotoxicity. The highest proportion of IFNgamma-producing cells was concentrated into the NK1.1+ cells..
