RNA病毒是最普遍的病原体之一,是社会的主要负担。虽然RNA病毒已被广泛研究,但由于缺乏敏感的检测方法,对感染最初几个小时内发生的过程知之甚少。在这里,我们开发了一种单分子成像分析,病毒感染实时成像(VIRIM),以研究活细胞中单个RNA病毒的翻译和复制。VIRIM揭示了细胞之间复制动力学的显著异质性,并揭示了单个病毒RNA的翻译和复制之间的广泛协调。此外,使用VIRIM,我们确定了传入病毒RNA的复制步骤作为成功感染的主要瓶颈,并确定了负责抑制早期病毒复制的宿主基因。病毒感染的单分子成像是研究病毒复制和病毒-宿主相互作用的有力工具,可能广泛适用于RNA病毒。研究+RNA病毒翻译和复制的单分子成像分析早期小RNA病毒感染发生在五个不同阶段病毒RNA翻译和复制的异质性传入vRNA的复制是宿主抗病毒活性的主要靶点Boersma等人。开发单分子成像分析(VIRIM),以研究+RNA病毒的翻译、复制和病毒-宿主相互作用。他们观察到单个病毒翻译和复制的异质性,确定传入病毒基因组的复制是成功感染的瓶颈,并确定介导这种抗病毒活性的宿主基因。
RNA viruses are among the most prevalent pathogens and are a major burden on society. Although RNA viruses have been studied extensively, little is known about the processes that occur during the first several hours of infection because of a lack of sensitive assays. Here we develop a single-molecule imaging assay, virus infection real-time imaging (VIRIM), to study translation and replication of individual RNA viruses in live cells. VIRIM uncovered a striking heterogeneity in replication dynamics between cells and revealed extensive coordination between translation and replication of single viral RNAs. Furthermore, using VIRIM, we identify the replication step of the incoming viral RNA as a major bottleneck of successful infection and identify host genes that are responsible for inhibition of early virus replication. Single-molecule imaging of virus infection is a powerful tool to study virus replication and virus-host interactions that may be broadly applicable to RNA viruses. Single-molecule imaging assay to study translation and replication of +RNA viruses Early picornavirus infection occurs in five distinct phases Heterogeneity in translation and replication of viral RNAs Replication of incoming vRNA represents major target for host antiviral activity Boersma et al. develop a single-molecule imaging assay (VIRIM) to study translation, replication, and virus-host interactions of +RNA viruses. They observe heterogeneity in translation and replication of single viruses, identify replication of the incoming viral genome as a bottleneck for successful infection, and identify host genes mediating this antiviral activity.
