title: Studies on the release of interleukin-1 (IL-1), tumor necrosis factor (TNF) and lysozyme from human non-adherent mononuclear cells (nMNC) in vitro after treatment with cisplatin and other biological response modifiers.
abstract: The supernatants collected from cisplatin, lipopolysaccharide (LPS), muramyl dipeptide (MDP) or recombinant interferon gamma (rIFN-gamma) treated non-adherent mononuclear cells (with NK cell activity) enhanced thymocyte proliferation by a submitogenic concentration of concanavalin A as compared to untreated nMNC. Supernatants collected from cisplatin or rIFN-gamma treated nMNC also demonstrated enhanced cytotoxicity against actinomycin-D treated L929 cells, suggesting that cisplatin or rIFN-gamma treated nMNC release tumor necrosis factor (TNF) into the culture supernatant. On the other hand, supernatant collected from untreated nMNC showed little TNF activity. Treatment of nMNC with cisplatin, LPS, MDP or rIFN-gamma resulted in enhanced release of lysozyme into the culture medium as compared to untreated nMNC.
