Resveratrol, a type of natural polyphenol mainly extracted from the skin of grapes, has been reported to protect against inflammatory responses and exert anxiolytic effect. Yes-associated protein (YAP), a major downstream effector of the Hippo signaling pathway, plays a critical role in inflammation. The present study aimed to explore whether YAP pathway was involved in the anxiolytic effect of resveratrol in lipopolysaccharide (LPS)-treated C57BL/6J male mice. LPS treatment induced anxiety-like behavior and decreased sirtuin 1 while increased YAP expression in the hippocampus. Resveratrol attenuated LPS-induced anxiety-like behavior, which was blocked by EX-527 (a sirtuin 1 inhibitor). Mechanistically, the anxiolytic effects of resveratrol were accompanied by a marked decrease in YAP, interleukin-1β and ionized calcium binding adaptor molecule 1 (Iba-1) while a significant increase in autophagic protein expression in the hippocampus. Pharmacological study using XMU-MP-1, a YAP activator, showed that activating YAP could induce anxiety-like behavior and neuro-inflammation as well as decrease hippocampal autophagy. Moreover, activation of YAP by XMU-MP-1 treatment attenuated the ameliorative effects of resveratrol on LPS-induced anxiety-like behavior, while blockade of YAP activation with verteporfin, a YAP inhibitor, attenuated LPS-induced anxiety-like behavior and neuro-inflammation as well as hippocampal autophagy. Finally, rapamycin-mediated promotion of autophagy attenuated LPS-induced anxiety-like behavior and decreased interleukin-1β and Iba-1 expression in the hippocampus. Collectively, these results indicate that amelioration by resveratrol in LPS-induced anxiety-like behavior is through attenuating YAP-mediated neuro-inflammation and promoting hippocampal autophagy, and suggest that inhibition of YAP pathway could be a potential therapeutic target for anxiety-like behavior induced by neuro-inflammation. •Resveratrol ameliorates LPS-induced anxiety-like behavior by attenuating YAP signaling.•YAP-mediated neuro-inflammation contributes to LPS-induced anxiety-like behavior.•Rapamycin prevents neuro-inflammation and attenuates LPS-induced anxiety-like behavior.•Blocking YAP could be a therapeutic target for LPS-induced anxiety-like behavior.
