人类疱疹病毒分为三个亚家族,是双链DNA病毒,在世界大多数人口中建立终身潜伏感染,可导致严重疾病,特别是在免疫功能低下的人中。没有治愈方法,目前的预防和治疗选择有限。因此,了解这些病毒的生物学特性对于找到阻止它们的新方法至关重要。衣壳在疱疹病毒生物学中起着核心作用。它们是复杂的载体,可以保护加压的双链DNA基因组,同时确保它们在进出宿主细胞的过程中运送到指定的细胞目的地。此外,衣壳在复制周期的多个关键步骤中的重要性使它们的组装成为一个有吸引力的治疗靶点。最近对人类疱疹病毒三个亚家族衣壳进行的冷冻电子显微镜重建不仅显示了保守的特征,而且还显示了显着的结构差异。此外,衣壳组装研究表明,病毒衣壳蛋白同源物具有亚家族特有的作用。在这篇综述中,我们比较了不同人类疱疹病毒亚家族的衣壳结构、组装机制和衣壳蛋白功能,强调了差异。
Human herpesviruses, classified into three subfamilies, are double-stranded DNA viruses that establish lifelong latent infections within most of the world’s population and can cause severe disease, especially in immunocompromised people. There is no cure, and current preventative and therapeutic options are limited. Therefore, understanding the biology of these viruses is essential for finding new ways to stop them. Capsids play a central role in herpesvirus biology. They are sophisticated vehicles that shelter the pressurized double-stranded-DNA genomes while ensuring their delivery to defined cellular destinations on the way in and out of the host cell. Moreover, the importance of capsids for multiple key steps in the replication cycle makes their assembly an attractive therapeutic target. Recent cryo-electron microscopy reconstructions of capsids from all three subfamilies of human herpesviruses revealed not only conserved features but also remarkable structural differences. Furthermore, capsid assembly studies have suggested subfamily-specific roles of viral capsid protein homologs. In this review, we compare capsid structures, assembly mechanisms, and capsid protein functions across human herpesvirus subfamilies, highlighting the differences.
