Microglia activation has been implicated in neurodegenerative disease. Sevoflurane is fluorinated methyl isopropyl ether with anti-inflammatory activity. In this study, we evaluated the potential effects of sevoflurane on lipopolysaccharides (LPS)-induced microglia activation. We treated primary microglia cells with sevoflurane prior to LPS treatment and tested the microglia migration, the productions of pro-inflammatory cytokines including tumor necrosis factor-α, interleukin-6 and interleukin-8. We also explored the effects of sevoflurane on NF-κB and p38 MAPK activation. Finally, we examined the effect of sevoflurane on cytokines production in rat brain. Sevoflurane significantly reduced LPS-induced microglial migration. Sevoflurane significantly decreased the production of pro-inflammatory cytokines both in vitro and in vivo. Sevoflurane attenuated activations of NF-κB and MAPK signaling pathways. Sevoflurane treatment decreased microglia activation by suppressing NF-kB and MAPK signaling pathways.
