    Abstract:
    The effect of macrophages on the induction of the cell-mediated cytotoxicity against a leukemia in a syngeneic system was investigated. The addition of exogenous peritoneal cells from normal C57BL/6 MIce enhanced the in vitro secondary cell-mediated cytotoxic response of both spleen and lymph node cells as responding cells against syngeneic FBL-3 leukemia. Peritoneal phagocytic macrophages seemed to be responsible for the enhancement. No inhibitory effect was demonstrated by the addition of peritoneal macrophages at a concentration as high as 20%, whereas the primary cytotoxic allograft response was significantly suppressed. In the present studies, there was no absolute restriction of macrophage-T cell interaction by an H-2 barrier. Supernatants of peritoneal macrophage cultures also enhanced this cell-mediated cytotoxic response. There was no difference between the effects of syngeneic or allogeneic peritoneal macrophage culture supernatants.
