1 Regulation of lipopolysaccharide-induced tumor necrosis factor alpha production by endogenous prostaglandin E2 in rat resident and thioglycollate-elicited macrophages. Thioglycolates tumor necrosis factor Rattus norvegicus
2 However, we have observed that a cyclooxygenase inhibitor had different effects on TNF alpha production by resident and thioglycollate-elicited rat peritoneal macrophages. Thioglycolates tumor necrosis factor Rattus norvegicus
3 The addition of free arachidonic acid to cultures of LPS-stimulated, thioglycollate-elicited macrophages elevated PGE2 production and suppressed TNF alpha production in a manner similar to that observed with LPS-stimulated resident macrophages. Thioglycolates tumor necrosis factor Rattus norvegicus
4 Instead, the inability of indomethacin to increase TNF alpha production by thioglycollate-elicited versus resident macrophages appears to result from an inability to release arachidonate efficiently and a lower initial level of cyclooxygenase, in thioglycollate-elicited macrophages. Thioglycolates tumor necrosis factor Rattus norvegicus
