RNA-Seq of U2OS cells with and without IFNα2 pretreatment


ABSTRACT: RNA viruses are among the most prevalent pathogens and represent a major burden on society. While RNA viruses have been studied extensively, little is known about the processes that occur during the first several hours of infection due to 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 represents a powerful tool to study virus replication and virus-host interactions that may be broadly applicable to RNA viruses.
