Abstract

Herpes Simplex Virus 1 (HSV-1) is a neurotropic human virus that belongs to the subfamily of . Establishment of its productive infection and progression of disease pathologies depend largely on successful release of virions from the virus-producing cells. HSV-1 is known to exploit many host factors for its release. Recent studies have shown that heparanase (HPSE) is one such host enzyme that is recruited for this purpose. It is an endoglycosidase that cleaves heparan sulfate (HS) from the surface of infected cells. HS is a virus attachment coreceptor that is commonly found on cell surfaces as HS proteoglycans e.g., syndecan-1 (SDC-1). The current model suggests that HSV-1 during the late stage of infection upregulates HPSE, which in turn enhances viral release by removing the virus-trapping HS moieties. In addition to its role in directly enabling viral release, HPSE accelerates the shedding of HS-containing ectodomains of SDC-1, which enhances HSV-1 release via a similar mechanism by upregulating CREB3 and COPII proteins. This review outlines the role of HPSE and SDC-1 as newly assigned host factors that facilitate HSV-1 release during a lytic infection cycle.

摘要

单纯疱疹病毒 1(HSV-1)是一种嗜神经的人类病毒,属于 亚科。其有性感染的建立和疾病病理的进展在很大程度上依赖于病毒从产病毒细胞中的有效释放。HSV-1 已知利用许多宿主因子来实现其释放。最近的研究表明,肝素酶(HPSE)就是这样一种被招募用于此目的的宿主酶。它是一种内切糖苷酶,可从受感染细胞的表面切割肝素硫酸(HS)。HS 是一种病毒附着核心受体,通常作为 HS 蛋白聚糖存在于细胞表面,例如, syndecan-1(SDC-1)。目前的模型表明,HSV-1 在感染的晚期上调 HPSE,反过来通过去除病毒捕获的 HS 部分来增强病毒释放。除了在直接促进病毒释放中的作用外,HPSE 还加速了 SDC-1 中含有 HS 的细胞外结构域的脱落,通过上调 CREB3 和 COPII 蛋白以类似的机制增强 HSV-1 的释放。这篇综述概述了 HPSE 和 SDC-1 作为新指定的宿主因子在裂解感染周期中促进 HSV-1 释放的作用。
