摘要

野生型单纯疱疹病毒(HSV)株在细胞培养中很少介导细胞-细胞融合，很少诱导大的多核细胞。在这项研究中，我们建立了一个系统来量化野生型HSV菌株诱导的罕见细胞-细胞融合。建立的系统明确了HSV-1包膜糖蛋白B及其在141位天冬酰胺上的n -糖基化是细胞-细胞有效融合所必需的。本研究提供了野生型HSV-1诱导的细胞-细胞融合与体内病毒发病机制之间的联系。

Establishment of a system to quantify wild-type herpes simplex virus–induced cell–cell fusion reveals a role of N-glycosylation of HSV-1 envelope glycoprotein B in cell–cell fusion

Wild-type herpes simplex virus (HSV) strains infrequently mediate cell–cell fusion in cell cultures and barely induce large multinucleated cells. In this study, we established a system to quantify infrequent cell–cell fusion induced by wild-type HSV strains. The established system clarified that the HSV-1 envelope glycoprotein B and its N-glycosylation at asparagine at position 141 were required for efficient cell–cell fusion. This study provides a link between cell–cell fusion induced by wild-type HSV-1 and viral pathogenesis in vivo.
