| In order to identify mechanisms responsible for the anti-tumor effects of Toxoplasma lysate antigen (TLA), we used an in vitro 51Cr release assay to study the functional properties of plastic-adherent cells during induction of splenic cytotoxic activity by TLA. Cytotoxic activity of non-adherent cells was measured in all experiments after a 6 days incubation. Induction of cytotoxic non-adherent cells by TLA required the presence of plastic-adherent spleen cells. In contrast, rhIL-2 alone was able to induce transformation of cytotoxic non-adherent cells from non-adherent spleen cells. Contact between adherent and non-adherent spleen cells was necessary for successful induction of cytotoxic non-adherent cells by TLA. Treatment of spleen cells with... |
