Abstract Cyclooxygenase-2 (COX-2) is a key inflammatory response molecule, and associated with many immune functions of monocytes/macrophages. Particularly, interferon gamma (IFNγ)-induced COX-2 expression appears in inflammatory conditions such as viral infection and autoimmune diseases. Recently, statins have been reported to show variable effects on COX-2 expression, and on their cell and species type dependences. Based on the above description, we compared the effect of simvastatin on IFNγ-induced COX2 expression in human monocytes versus murine macrophages. In a result, we found that simvastatin suppresses IFNγ-induced COX-2 expression in human THP-1 monocytes, but rather, potentiates IFNγ-induced COX-2 expression in murine RAW264.7 macrophages.
