Exosomes: the ideal nanovectors for biodelivery

Area of Science:

• Nanomedicine and biomaterials science.
• Cell biology and extracellular vesicle research.

Background:

• Nanomedicine leverages nanoscale material properties, with exosomes being key nanovesicles.
• Exosomes, unlike larger microvesicles, possess suitable size for nanomedicine applications.
• Exosomes mediate intercellular communication, influencing target cells via various mechanisms.

Purpose of the Study:

• To critically review existing literature on the diagnostic and therapeutic potential of exosomes.
• To highlight the complex and often unknown roles of exosomes in both normal and pathological conditions.

Main Methods:

• Literature review and critical analysis of scientific data.
• Focus on exosome properties, interactions, and effects.

Main Results:

• Exosomes from normal cells generally have positive effects, while those from pathological cells can be detrimental.
• Exosomes may exert unintended effects even in normal physiological states, influenced by factors like gender and age.
• The full impact of exosomes remains largely uncharacterized, akin to an iceberg.

Conclusions:

• Exosomes hold significant promise for diagnostic and therapeutic applications in nanomedicine.
• Further research is crucial to fully understand exosome behavior and mitigate potential risks.
• Comprehensive understanding of exosome biology is essential for safe and effective nanomedical interventions.
