Herpesviruses are DNA viruses and the cause of diseases ranging from mild skin conditions to severe brain diseases. Mammalian antiviral host defense comprises an array of mechanisms, including restriction factors (RFs), which block specific steps in viral replication cycles. In recent years, knowledge of RFs that contribute to controlling herpesvirus infections has expanded significantly, along with a new understanding of viral evasion mechanisms and disease pathogenesis. By integrating findings from human genetics, murine models, and cellular studies, this review provides a current view of RF control of herpesvirus infections. We also explore the regulation of RF expression, discuss the roles of RFs in diseases, and point towards their growing potential as candidate therapeutic targets.
Keywords: herpesvirus; innate immunity; restriction factors; virus–host interactions.
