第二种人类 Pegivirus (HPgV-2) 是 2015 年在丙型肝炎病毒 (HCV) 感染患者血浆中发现的一种病毒,属于黄病毒科 Pegivirus。 HPgV-2已被证明在流行病学上与HCV相关且结构相似,但与HCV疾病无关且非致病性,但其自然史和组织向性仍不清楚。 HPgV-2 是一种独特的 RNA 病毒,具有 HCV 和第一种人类 Pegivirus(HPgV-1 或 GBV-C)的特征。此外,与大多数RNA病毒(如HCV、HPgV-1和人类免疫缺陷病毒(HIV))不同,HPgV-2表现出低得多的基因组多样性,具有93.5%至97.5%的高全局序列同一性,并且宿主内变异显着低于HCV。 HPgV-2 基因组保守的机制尚不清楚,但可能包括有效的先天免疫反应、低免疫选择压力以及可能的病毒 RNA 依赖性 RNA 聚合酶 (RdRP) 的独特特征。在这篇综述中,我们总结了 HPgV-2 的患病率、致病性和遗传多样性,并讨论了其基因组序列一致性的可能原因,这应该阐明 RNA 病毒保真度对减毒病毒疫苗的影响。
The second human pegivirus (HPgV-2) is a virus discovered in the plasma of a hepatitis C virus (HCV)-infected patient in 2015 belonging to the pegiviruses of the family Flaviviridae. HPgV-2 has been proved to be epidemiologically associated with and structurally similar to HCV but unrelated to HCV disease and non-pathogenic, but its natural history and tissue tropism remain unclear. HPgV-2 is a unique RNA virus sharing the features of HCV and the first human pegivirus (HPgV-1 or GBV-C). Moreover, distinct from most RNA viruses such as HCV, HPgV-1 and human immunodeficiency virus (HIV), HPgV-2 exhibits much lower genomic diversity, with a high global sequence identity ranging from 93.5 to 97.5% and significantly lower intra-host variation than HCV. The mechanisms underlying the conservation of the HPgV-2 genome are not clear but may include efficient innate immune responses, low immune selection pressure and, possibly, the unique features of the viral RNA-dependent RNA polymerase (RdRP). In this review, we summarize the prevalence, pathogenicity and genetic diversity of HPgV-2 and discuss the possible reasons for the uniformity of its genome sequence, which should elucidate the implications of RNA virus fidelity for attenuated viral vaccines.
