Exosomes, and the potential for exosome-based interventions against COVID-19

Area of Science:

• Biomedical Science
• Virology
• Nanotechnology

Background:

• Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, has led to significant global morbidity and mortality.
• Current treatments for COVID-19 are limited, necessitating the development of novel therapeutic strategies.
• Exosomes, small extracellular vesicles, are implicated in viral infections and disease transmission.

Purpose of the Study:

• To discuss the significance and roles of exosomes in the context of COVID-19.
• To explore the potential of exosome-based therapies for treating COVID-19 and other viral diseases.
• To investigate the therapeutic potential of synthetic and mesenchymal stem cell-derived exosomes.

Main Methods:

• Review of existing literature on exosomes and their role in viral infections.
• Analysis of how SARS-CoV-2 impacts exosome formation, secretion, and release.
• Exploration of exosome engineering for therapeutic cargo delivery.

Main Results:

• SARS-CoV-2 can manipulate exosome pathways to facilitate viral transmission.
• Synthetic exosomes engineered with antiviral compounds and immunomodulatory cargo show therapeutic potential.
• Mesenchymal stem cell-derived exosomes can mitigate COVID-19's cytokine storm and promote lung repair.

Conclusions:

• Exosome-based therapies represent a promising strategy for combating COVID-19 and other viral infections.
• Targeting exosome pathways offers a novel approach to antiviral treatment.
• Further research into exosome engineering and application is warranted for improved patient outcomes.
