Extracellular Vesicles in Skin: Biological Function and Therapeutic Potential

Area of Science:

• Dermatology
• Cell Biology
• Nanomedicine

Background:

• Extracellular vesicles (EVs) are vital for tissue homeostasis, mediating cell-to-cell communication through bioactive molecule delivery.
• Research into EV functions in skin physiology and disease has significantly expanded over the last decade.

Purpose of the Study:

• To review the biogenesis, composition, and cellular uptake of EVs.
• To critically evaluate the therapeutic effects and mechanisms of EVs from various sources in skin diseases.
• To discuss challenges and future directions for EV-based therapeutics in dermatology.

Main Methods:

• Literature review of EV research in cutaneous applications.
• Analysis of EV biogenesis, cargo, and uptake mechanisms.
• Synthesis of findings on therapeutic applications in skin wound healing, hair growth, aging, inflammatory diseases, and cancers.

Main Results:

• EVs orchestrate essential biological processes including proliferation, angiogenesis, and immune responses.
• EVs from mammalian, plant, and bacterial sources show therapeutic promise for diverse skin conditions.
• Understanding EV mechanisms is crucial for their effective application in treating skin diseases.

Conclusions:

• EVs represent a promising therapeutic avenue for various skin diseases.
• Further research is needed to overcome clinical translation challenges for EV-based dermatology treatments.
• Future directions focus on optimizing EV production, characterization, and delivery for clinical use.
