title: Modification of murine T-cell cytotoxicity by preimmunization with M locus and H-2 incompatibilities.
abstract: The effect of preimmunization of CBA/H mice with M locus and H-2 incompatible lymphocytes was examined on the in vitro generation of cytotoxic cells to both types of targets. Preimmunization with M locus did not help to generate cytotoxic cells to M-locus targets; however, the anti-H-2 cytotoxicity of M-locus-preimmunized lymphocytes was suppressed between the 6th and 19th day after preimmunization. In contrast, preimmunization with H-2 incompatibility produced an amplified lytic anti-H-2 response. The possible mechanisms are discussed.
