Scutellarin suppresses neuroinflammation via the inhibition of the AKT/NF-κB and p38/JNK pathway in LPS-induced BV-2 microglial cells.
In vitro and in vivo studies indicate that scutellarin (SCU) exerts anti-inflammatory effects in the central nervous system (CNS) and inhibits microglia activation. This study investigated the anti-neuroinflammation molecular mechanisms exerted by scutellarin in LPS-induced BV-2 cells. ⋯ Consistent with the inhibition of NF-κB, scutellarin inhibited the phosphorylation of p38, JNK, and AKT without affecting phosphorylation of ERK1/2 or PI3K in LPS-induced BV-2 cells. Overall, the present study suggests that scutellarin inhibits the production of pro-inflammatory mediators via inhibition of the IKK-dependent NF-κB and p38/JNK signaling pathway, which inhibits microglia activation and exerts anti-inflammation, indicating its potential therapeutic effect for neurodegenerative and cerebrovascular diseases.
