a subcutaneous inoculation of the mixture of ctll-d4 and rl male 1 cells resulted in the complete inhibition of tumour growth , even at the effector to tumour cell ratio of 1:1 , whereas non-cytolytic d4f , which was self-ia antigen ( s ) -reactive , composed entirely of lyt-1+23- t cells and derived originally from ctll-d4 but completely lost its cytotoxic activity during culture with the irradiated syngeneic feeder cells alone , had no inhibitory effect at all .
