title: Xenogenic response of human peripheral blood lymphocytes against murine cells in vitro.
abstract: Human peripheral blood lymphocytes (HPBL) were sensitized to mitomycin-treated murine spleen cells and mitomycin-treated mastocytoma P-815. A DNA proliferative response occurred to both cell types. The sensitized HPBL lysed chromium-51-labelled mastocytoma P-815 cells in a cell-mediated cytotoxicity assay (CMC). Evidence is presented that this human-murine xenogeneic system involves T cell response with specificity in CMC mainly toward H-2 antigens. DBA/2 splenocytes were superior to mastocytoma cells as sensitizers in the xenogeneic DNA proliferative assay.
