ABSTRACT
Resveratrol, a natural polyphenolic antioxidant found in red wine and grapes, has been reported to exert a variety of important pharmacological effects, including anti-inflammatory, cardioprotective, and cancer chemopreventive properties. In the present study, we investigated the effect of resveratrol on the production of nitric oxide (NO) and prostaglandin (PG) E2 by lipopolysaccharide (LPS)-activated C6 microglia. Exposure of cultured rat C6 astroglioma cells to LPS increased their release of NO and PGE2 and their inducible expression of NO synthase and cyclooxygenase-2, all of which were significantly inhibited by resveratrol pretreatment. Further studies revealed that resveratrol suppressed LPS-induced nuclear translocation and activation of nuclear factor kappaB (NF-kappaB). These results demonstrate a potent suppressive effect of resveratrol on pro-inflammatory responses of microglia by modulation of NF-kappaB activity, suggesting a therapeutic potential for this compound in neurodegenerative diseases accompanied by microglial activation.
