Extracellular vesicles (EVs) are increasingly acknowledged as important mediators of intercellular communication, closely related to the occurrence and development of a variety of diseases. Numerous studies have demonstrated that EVs play a multifaceted role in the infection process of viral diseases, elucidating their ability to both facilitate viral spread and inhibit infection progression. These versatile entities not only enhance infection rates and widen the scope of viral infection through the transmission of entire viruses or viral genomes, but also trigger antiviral responses and prompt cytokine secretion near the infection site, thereby fortifying the host's defense mechanisms and safeguarding neighboring cells against infection. This complicated crosstalk between EVs and viral infections prompts a deeper exploration into their roles in potential clinical applications. In this review, we aim to encapsulate the recent advances in understanding the intricate interplay between viruses and EVs, shedding light on the mechanisms underlying this vesicle-to-virion crosstalk. Furthermore, we underscore the significance of harnessing this knowledge for diagnostic and therapeutic functions in combating viral diseases., Competing Interests: All authors declared that there are no conflicts of interest., (© The Author(s) 2024.)
