Anti-inflammatory activity of retinoids has been demonstrated earlier, but their mechanism is
poorly understood. In this study, we examined the effects of retinoids on lipopolysaccharide
(LPS)-induced prostaglandin (PG) E2 production, an indicator of cyclooxygenase (COX)
activity, and COX-2 protein expression in mouse peritoneal macrophages, and tumor
necrosis factor (TNF)-α release in rat peripheral blood mononuclear cell (PBMC) to elucidate
their possible mechanism for anti-inflammation. All-trans retinoic acid (t-RA) and all-trans …
