Abstract:
:We have investigated the role of arachidonic acid metabolites in the regulation of interleukin-1 production by murine peritoneal macrophages. Indomethacin a potent inhibitor of prostaglandin synthesis caused a dose-dependent augmentation of lipopolysaccharide induced interleukin production (up to 7-fold at 5 microM). In contrast, lipoxygenase inhibitors, nordihydroguarietic acid and nafazatrom had no effect at doses that did not significantly decrease prostaglandin synthesis. Added to lipopolysaccharide stimulated cultures, PGE2 was also augmented by indomethacin but unlike lipopolysaccharide treated cultures was suppressed by nordihydroguarietic acid. These data suggest that arachidonate metabolites may be potent autoregulators of macrophage interleukin-1 production.
