摘　　要：Depression is a serious public-health issue.Recent reports have suggested higher susceptibility to viral infections in depressive patients.However,how depression affects antiviral innate immune signaling remains unknown.Here,we revealed a reduction in expression of Abelson helper integration site 1(AHI1)in the peripheral blood mononuclear cells(PBMCs)and macrophages from the patients with major depressive disorder(MDD),which leads to attenuated antiviral immune response.We found that depression-related arginine vasopressin(AVP)induces reduction of AHI1 in macrophages.Further studies demonstrated that AHI1 is a critical stabilizer of basal type-I-interferon(IFN-I)signaling.Mechanistically,AHI1 recruits OTUD1 to deubiquitinate and stabilize Tyk2,while AHI1 reduction downregulates Tyk2 and IFN-I signaling activity in macrophages from both MDD patients and depression model mice.Interestingly,we identified a clinical analgesic meptazinol that effectively stimulates AHI1 expression,thus enhancing IFN-I antiviral defense in depression model mice.Our study promotes the understanding of the signaling mechanisms of depression-mediated antiviral immune dysfunction,and reveals meptazinol as an enhancer of antiviral innate immunity in depressive patients.
