Picornavirus infection induces temporal release of multiple extracellular vesicle subsets that differ in molecular composition and infectious potential.

abstract：:Positive-strand RNA viruses replicate in host cells by forming large viral replication organelles, which harbor numerous membrane-bound viral replicase complexes (VRCs). In spite of its essential role in viral replication, the biogenesis of the VRCs is not fully understood. The authors identified critical roles of cel...
