1 Human neutrophils, plated on fibronectin-coated polystyrene wells, were found to exhibit a prolonged production of superoxide anion (O2-) in response to tumour necrosis factor-alpha (TNF). Superoxides tumor necrosis factor Homo sapiens
2 Human neutrophils, plated on fibronectin-coated polystyrene wells, were found to exhibit a prolonged production of superoxide anion (O2-) in response to tumour necrosis factor-alpha (TNF). Superoxides tumor necrosis factor Homo sapiens
3 The TNF-triggered O2- production was significantly reduced by 10 microM prostaglandin E2 (PGE2), which was ineffective at lower doses. Superoxides tumor necrosis factor Homo sapiens
4 When PGE2 and RO 20-1724 were added together to TNF-triggered neutrophils they caused a marked synergistic inhibition of O2- production. Superoxides tumor necrosis factor Homo sapiens
5 Moreover, the membrane-permeable analogue of cAMP, dibutyryl cAMP, was found to inhibit the TNF-induced O2- production in a dose-dependent manner. Superoxides tumor necrosis factor Homo sapiens
