Exosomes in Cardiovascular Disease: Emerging Roles, Therapeutic Potential and Translational Challenges

Area of Science:

• Cardiovascular Medicine
• Regenerative Medicine
• Biotechnology

Background:

• Cardiovascular diseases (CVDs) are a leading cause of death globally.
• Myocardial injury, adverse remodeling, and impaired cardiomyocyte regeneration are key challenges in CVDs.
• Exosomes are crucial intercellular communicators influencing cardiac health and disease.

Purpose of the Study:

• To explore the therapeutic and diagnostic potential of exosomes in cardiovascular regenerative medicine.
• To review the mechanisms by which exosomes mediate cardiac repair and regeneration.
• To identify current challenges and future directions for exosome-based cardiovascular therapies.

Main Methods:

• Review of preclinical and clinical studies on exosome therapy for CVDs.
• Analysis of exosome cargo (nucleic acids, proteins, lipids) and their roles in cardiac processes.
• Evaluation of challenges in exosome isolation, characterization, and clinical application.

Main Results:

• Exosomes, particularly from stem and immune cells, demonstrate regenerative capabilities in preclinical models.
• Exosomes modulate cytoprotection, angiogenesis, apoptosis, and immune responses critical for cardiac repair.
• Diagnostic applications of exosomes in CVD management are a nearer-term goal.

Conclusions:

• Exosomes offer a promising cell-free therapeutic strategy for cardiovascular diseases.
• Standardization of protocols, overcoming heterogeneity, and ensuring safety are crucial for clinical translation.
• Further research is needed to fully harness exosome potential in cardiovascular regenerative medicine.
