Abstract:
:The mechanism of tumour necrosis factor-mediated cytotoxicity was investigated by using various inhibitors of arachidonic acid metabolism. Phospholipase A2 inhibitors with different modes of action interfered with the cytotoxic action of TNF, whereas phospholipase C inhibitors did not. Neither cyclooxygenase nor lipoxygenase-blockers had a significant effect on TNF action. Experiments with scavengers of toxic oxygen radicals gave ambiguous results. The data obtained suggest the involvement of phospholipase A2 and arachidonic acid in the cytotoxic mechanism of TNF, but the exact role of these molecules is, however, still to be determined.
