Resveratrol counteracts lipopolysaccharide-mediated microglial inflammation by modulating a SOCS-1 dependent signaling pathway

Abstract

Brain damage or exposure to inflammatory agents provokes the activation of microglia and secretion of pro-inflammatory and neurotoxic mediators responsible for neuronal loss. Several lines of evidence show that resveratrol, a natural non-flavonoid polyphenol, may exert a neuroprotective action in neurodegenerative diseases. Suppressor of cytokine signaling (SOCS) proteins are a family of eight members expressed by immune cells and the central nervous system (CNS) cells, that regulate immune processes within the CNS, including microglia activation. We demonstrate that resveratrol had anti-inflammatory effects in murine N13 microglial cells stimulated with lipopolysaccharide (LPS), through up-regulating SOCS-1 expression. Interestingly, in SOCS-1-silenced cells resveratrol failed to play a protective role after LPS treatment. Our data demonstrate that resveratrol can impair microglia activation by activating a SOCS-1 mediated signaling pathway
