Exosomes and COVID-19: challenges and opportunities

Area of Science:

• Biomedical Sciences
• Molecular Biology
• Virology

Background:

• Coronavirus disease 2019 (COVID-19) presents a global health crisis, necessitating understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection mechanisms.
• Exosomes, as extracellular vesicles, are implicated in disease pathogenesis and intercellular communication, suggesting a potential role in COVID-19.

Purpose of the Study:

• To review the biogenesis and contents of exosomes.
• To elucidate the function of exosomes in viral infections, particularly SARS-CoV-2.
• To explore the therapeutic potential of exosomes in managing COVID-19.

Main Methods:

• Literature review focusing on exosome biology and their role in viral pathogenesis.
• Analysis of current research on exosome involvement in SARS-CoV-2 infection.
• Evaluation of exosomes as therapeutic agents or drug delivery vehicles for COVID-19.

Main Results:

• Exosomes are involved in the pathogenesis of various diseases, including viral infections.
• Exosomes may facilitate the transfer of SARS-CoV-2 components, contributing to infection spread.
• Exosomes show promise as diagnostic biomarkers and therapeutic strategies for COVID-19.

Conclusions:

• Understanding exosome function in COVID-19 is crucial for developing effective treatments.
• Exosomes represent a potential therapeutic avenue for COVID-19, either directly or as drug carriers.
• Further research into exosome-host interactions in SARS-CoV-2 infection is warranted.
