Abstract

Following in vitro stimulation of murine sarcoma virus Moloney isolate (M-MuSV)-immune spleen cells with syngeneic antigenically related Moloney leukemia cells, highly efficient cytotoxic T-lymphocytes (CTL's) were generated. The cytotoxic effect was directed only against H-2-compatible target cells bearing M-MuSV tumor-associated antigens (TAA). However, in a cold target competition assay a weak but detectable capacity to block CTL activity was also obtained when allogeneic Moloney leukemia cells were added. Moreover, when M-MuSV-immune spleen cells from mice inoculated with virus 14 days previously were stimulated by allogeneic Moloney leukemia cells, a strong cytotoxic effect toward syngeneic and allogeneic tumor cells bearing M-MuSV TAA was elicited.
