Cover Story: Extracellular vesicles (EVs) are small membrane-enclosed structures that play a crucial role in facilitating intracellular communication via the transport of proteins, lipids, DNA, rRNA, and miRNAs. EVs have been exploited by a wide range of viruses in order to egress from the host cell and eventually evade the host immune response. Due to the cross-talk between pathways involved in EV biogenesis and the replication of a number of viruses, EVs can incorporate viral fragments, proteins, RNA or entire virions within themselves. Thus, the host immune system often remains unaware of the trafficking of these viral components. Owing to this intricate relationship between Evs and viruses, numerous studies have identified various EV-mediated viral infections and interrogated how Evs can alter the overall spread and longevity of viruses.
