Cell-Mediated Immunity to Antigens Associated with Endogenous Murine C-Type Leukemia Viruses

Abstract

Splenic lymphocytes from (BALB/c times A/J) F 1 mice are cytotoxic for BALB/c fibroblasts infected with an endogenous C-type leukemia virus, but are not cytotoxic for uninfected BALB/c fibroblasts. These results indicate that mice do not exhibit cell-mediated immune tolerance to antigens associated with endogenous C-type viruses.
