Real-Time Dissection of the Exosome Pathway for Influenza Virus Infection

Scientists developed a dual-color exosome labeling strategy that simultaneously labels the external and internal structures of exosomes with quantum dots to enable in situ monitoring of the transport process of vExos in live cells using the single-particle tracking technique. Our finding revealed that vExos contains the complete influenza A virus genome and viral ribonucleoprotein complexes proteins but lacks viral envelope proteins.
