1 TNF-alpha sensitizes normal and fibrotic human lung fibroblasts to Fas-induced apoptosis. ammonium ferrous sulfate tumor necrosis factor Homo sapiens
2 Using normal and fibrotic human lung fibroblasts and the human lung fibroblast cell line, MRC-5, we examined the regulation of Fas-induced apoptosis by the proinflammatory cytokines TNF-alpha and IFN-gamma. ammonium ferrous sulfate tumor necrosis factor Homo sapiens
3 Herein, we show that the basal resistance of lung fibroblasts and myofibroblasts to Fas-induced apoptosis is overcome by sensitization with TNF-alpha. ammonium ferrous sulfate tumor necrosis factor Homo sapiens
4 Sensitization by TNF-alpha was observed in MRC-5 cells and in fibroblasts and myofibroblasts from normal and fibrotic human lung, suggesting that this represents a conserved mechanism to engage Fas-induced apoptosis. ammonium ferrous sulfate tumor necrosis factor Homo sapiens
