Exosomes in Corneal Homeostasis and Wound Healing

Area of Science:

• Ophthalmology
• Cell Biology
• Regenerative Medicine

Background:

• The cornea, a transparent avascular tissue, is crucial for vision and defense but vulnerable to environmental stress, leading to disease.
• Extracellular vesicles (EVs), including exosomes, are key mediators of cell-to-cell communication.
• Dysfunctional exosomes released by stressed corneal cells contribute to corneal disease pathogenesis.

Purpose of the Study:

• To review the current understanding of exosome biology in corneal disease and wound healing.
• To explore the therapeutic potential of EVs and exosomes in treating corneal conditions.
• To investigate the role of EVs and exosomes as diagnostic biomarkers in ocular and systemic diseases.

Main Methods:

• Literature search using PubMed and Google Scholar.
• Keywords included "exosomes," "extracellular vesicles," and "cornea."
• Focused review on studies examining EV roles in corneal wound healing and therapy.

Main Results:

• EVs and exosomes are integral to maintaining corneal homeostasis.
• These vesicles show significant potential as therapeutics for corneal wound healing and disease treatment.
• Exosomes in tear fluid may serve as diagnostic biomarkers for various diseases.

Conclusions:

• Corneal exosome biology is an emerging field with substantial potential.
• Continued research will enhance understanding of exosome function in the human cornea.
• This knowledge may facilitate the development of novel regenerative therapies for corneal conditions.
