I. Establishment of a human T-cell hybridoma that produces macrophage-activating factors for cytotoxicity. PG - 469-79 AB - Human T cell hybridoma, H3-E9-6, that produces macrophage activating factors for cytotoxicity (MAF-C) was prepared by somatic fusion of phytohemagglutinin-activated peripheral blood lymphocytes with emetine/actinomycin D-treated cloned human acute lymphocytic leukemia cells (CEM 11). The activities of the following were assayed: (1) macrophage-activating factor for cytotoxicity of monocytes (MAF-C 1 day), (2) macrophage-activating factor for cytotoxicity of monocyte-derived macrophages (MAF-C 6 day), (3) macrophage-activating factor for cytotoxicity of murine macrophages (MAF-Cm), (4) macrophage-activating factor for glucose consumption (MAF-G), (5) macrophage-activating factor for O2- formation (MAF-O). The culture supernatant of H3-E9-6 showed MAF-C 1 day-MAF-C 6 day, MAF-Cm, and MAF-G activities. The MAF-Cm activity was considerably enhanced by the addition of murine recombinant interferon gamma (rIFN-gamma). The MAF-C 1 day activity in the H3-E9-6 sup was not decreased by heat treatment (56 C, 30 min), by pH 2 treatment or by the addition of monoclonal anti-human IFN-gamma antibody or polymyxin B. These data suggest that MAF-C in H3-E9-6 sup is distinct from human IFN-gamma or lipopolysaccharide (LPS).
