摘 要:Psychological stress increases the susceptibility to herpes simplex virus type 1(HSV-1)infection.There is no effective intervention due to the unknown pathogenesis mechanisms.In this study we explored the molecular mechanisms underlying stress-induced HSV-1 susceptibility and the antiviral effect of a natural compound rosmarinic acid(RA)in vivo and in vitro.Mice were administered RA(11.7,23.4 mg·kg^(−1)·d^(−1),i.g.)or acyclovir(ACV,206 mg·kg^(−1)·d^(−1),i.g.)for 23 days.The mice were subjected to restraint stress for 7 days followed by intranasal infection with HSV-1 on D7.At the end of RA or ACV treatment,mouse plasma samples and brain tissues were collected for analysis.We showed that both RA and ACV treatment significantly decreased stress-augmented mortality and alleviated eye swelling and neurological symptoms in HSV-1-infected mice.In SH-SY5Y cells and PC12 cells exposed to the stress hormone corticosterone(CORT)plus HSV-1,RA(100μM)significantly increased the cell viability,and inhibited CORT-induced elevation in the expression of viral proteins and genes.We demonstrated that CORT(50μM)triggered lipoxygenase 15(ALOX15)-mediated redox imbalance in the neuronal cells,increasing the level of 4-HNE-conjugated STING,which impaired STING translocation from the endoplasmic reticulum to Golgi;the abnormality of STING-mediated innate immunity led to HSV-1 susceptibility.We revealed that RA was an inhibitor of lipid peroxidation by directly targeting ALOX15,thus RA could rescue stress-weakened neuronal innate immune response,thereby reducing HSV-1 susceptibility in vivo and in vitro.This study illustrates the critical role of lipid peroxidation in stress-induced HSV-1 susceptibility and reveals the potential for developing RA as an effective intervention in anti-HSV-1 therapy.
