摘要

Neurotropic viruses invade neural tissues, resulting in severe diseases such as poliomyelitis, rabies, herpesviral encephalitis, and viral meningitis. Given this neurotropism, we investigated whether the infection of the host by these viruses is under circadian control. In this study, we found that the expression of most neurotropic virus receptors exhibits rhythmicity across cells, cerebral organoids, and animal models, with host cell susceptibility modulated by the circadian clock. We identified E2F8 as a clock-controlled gene that mediates the indirect regulation of the circadian clock on neurotropic viruses. Notably, E2F8 regulated the expression of core clock components by binding directly to the promoters of REV-ERBα and PER2, suggesting its role as a potential modulator of circadian rhythms. Additionally, we revealed a seldom-recognized viral strategy to accelerate viral replication in the host: rabies virus disrupts the host circadian clock system primarily through its glycoprotein hijacking the E3 ubiquitin ligase HUWE1 to inhibit proteasomal degradation of REV-ERBα. These findings increase our understanding of the interactions between circadian systems and neurotropic viral dynamics and highlight the potential of chronotherapy for improved antiviral treatments.
