Primary in vitro sensitization of murine lymphocytes against isogeneic and allogeneic cells transformed by simian virus 40.
Primary in vitro sensitization of murine lymphocytes to isogeneic and allogeneic cells transformed by simian virus 40 (SV40) is described. The results of specificity studies utilizing cytotoxic effector lymphocytes obtained by in vitro immunization indicate that SV40 transformation results in the expression of tumor-specific antigens which are recognized by cytotoxic effector cells. Moreover, the studies demonstrate that expression of tumor-specific antigens on transformed cells is associated with a reduction in the functional expression of normal histocompatibility antigens.
