由严重急性呼吸综合征冠状病毒2型(SARS-CoV-2)引起的2019年冠状病毒病大流行正在持续,对全球公共卫生和社会稳定构成严重威胁。迫切需要了解这种病毒的性质和感染机制。由于其高传染性和致病性以及缺乏有效的治疗方法,活的SARS-CoV-2必须在生物安全3级实验室处理,这阻碍了对SARS-CoV-2的研究以及疫苗和治疗方法的开发。缺乏毒力病毒某些基因序列的假型病毒更安全,可在生物安全二级实验室进行研究,为研究SARS-CoV-2提供了有用的病毒学工具。在这篇综述中,我们将讨论基于不同包装系统的SARS-CoV-2假病毒的构建、目前的应用、局限性和进一步的探索。
The ongoing coronavirus disease 2019 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has posed a serious threat to global public health and social stability. There is an urgent need for understanding the nature and infection mechanism of the virus. Owing to its high infectivity and pathogenicity and lack of effective treatments, live SARS-CoV-2 has to be handled in biosafety level 3 laboratories, which has impeded research into SARS-CoV-2 and the development of vaccines and therapeutics. Pseudotyped viruses that lack certain gene sequences of the virulent virus are safer and can be investigated in biosafety level 2 laboratories, providing a useful virological tool for the study of SARS-CoV-2. In this review, we will discuss the construction of SARS-CoV-2 pseudoviruses based on different packaging systems, current applications, limitations, and further explorations.
