Bee Venom and Melittin Reduce Proinflammatory Mediators in Lipopolysaccharide-Stimulated BV2 MicrogliaInternational Immunopharmacology, 2007, In Press
Abstract: Bee venom (BV), well known as a traditional Oriental medicine, has been shown to exhibit anti-arthritic and anti-carcinogenic effects. However, the molecular mechanisms responsible for the anti-inflammatory activity of BV have not been elucidated in microglia. In the present study, we investigated the anti-inflammatory effect of BV and its major component, melittin (MEL), on lipopolysaccharide (LPS)-stimulated BV2 microglia. Our results indicate that BV and MEL suppress LPS-induced nitric oxide (NO) and inducible NO synthase (iNOS) expression in a dose-dependent manner, without causing cytotoxicity in BV2 microglia…
These results demonstrate that BV and MEL possess a potent suppressive effect on proinflammatory responses of BV2 microglia and suggest that these compounds may offer substantial therapeutic potential for treatment of neurodegenerative diseases that are accompanied by microglial activation.
