原发性水痘带状疱疹病毒 (VZV) 感染会导致水痘,这仍然是儿童中一个突出的公共卫生问题。目前的水痘疫苗采用减毒活 Oka 菌株 vOka,它保留了感染神经元、建立潜伏期和重新激活的能力,导致一些疫苗接种者出现疫苗相关带状疱疹。因此,有必要开发更安全的下一代水痘疫苗,以帮助减少疫苗犹豫。本文综述了亲皮肤和神经因子、VZV 开放阅读框 7 (ORF7) 的发现和鉴定,以及包含 ORF7 缺陷突变体 v7D 的皮肤和神经减毒活水痘疫苗的开发。这项工作可以为基于功能基因组学和反向遗传学的新型病毒疫苗的研究提供见解。
Primary varicella-zoster virus (VZV) infection causes varicella, which remains a prominent public health concern in children. Current varicella vaccines adopt the live-attenuated Oka strain, vOka, which retains the ability to infect neurons, establish latency and reactivate, leading to vaccine-associated zoster in some vaccinees. Therefore, it is necessary to develop a safer next-generation varicella vaccine to help reduce vaccine hesitancy. This paper reviews the discovery and identification of the skin- and neuro-tropic factor, the open reading frame 7 (ORF7) of VZV, as well as the development of a skin- and neuro-attenuated live varicella vaccine comprising an ORF7-deficient mutant, v7D. This work could provide insights into the research of novel virus vaccines based on functional genomics and reverse genetics.
