INTRODUCTION/BACKGROUND: Extracellular vesicles (EVs) are non-replicating lipid-bilayered bodies that are naturally released by a cell that aid in various biological functions including cell-to-cell communication. They resemble the cells that they originate from, mimicking their composition and contents. The shared Endosomal Sorting Complex Required for Transport (ESCRT) mechanism between virions and EVs allows EVs to aid in the dispersion and infection of viruses.
SCOPE/OBJECTIVES: The aim of this review is to encapsulate important studies that highlight the potential use of EVs in diagnosis and therapeutics against viral diseases. It also discusses their benefits and limitations compared to currently available anti-virals, for their use in the medical sector.
SUMMARY OF KEY FINDINGS: Virus-infected host cells release extracellular vesicles that are markedly different from EVs secreted by a healthy host cell. Increase in certain biomarker levels in EVs prove to be highly beneficial in diagnostics. Depending on the cell source, EVs also exhibit the natural ability to defend against viral diseases. This innate ability to defend against viral infections, can thus be exploited to produce potent anti-viral responses in infected hosts.
CONCLUSION/IMPLICATIONS: By navigating the challenges associated with EVs, they can be utilised to prepare alternatives to anti-viral drugs currently available in the market that show low specificity and high toxicity, thus helping mitigate and manage viral diseases.
