Exosomes: mediators regulating the phenotypic transition of vascular smooth muscle cells in atherosclerosis

Area of Science:

• Biomedical Science
• Molecular Biology
• Cardiovascular Research

Background:

• Cardiovascular disease (CVD) is a primary global mortality cause, with atherosclerosis (AS) being a major contributor.
• Vascular smooth muscle cell (VSMC) phenotypic transition is a critical process in AS development.
• Exosomes mediate intercellular communication via nucleic acids and proteins, implicating them in AS pathogenesis.

Purpose of the Study:

• To review the role of exosomes in VSMC phenotypic transition within the context of AS.
• To analyze the current understanding of exosome function in AS from various viewpoints.
• To identify research gaps and future directions for AS clinical research and treatment.

Main Methods:

• Literature review focusing on exosome function in atherosclerosis.
• Analysis of studies examining VSMC phenotypic transition.
• Synthesis of current research on exosome-mediated intercellular communication in AS.

Main Results:

• Exosomes significantly influence VSMC phenotypic transition, impacting AS progression.
• Evidence highlights diverse mechanisms by which exosomes affect AS.
• The field currently has limitations requiring further investigation.

Conclusions:

• Exosomes are key players in AS pathogenesis through modulation of VSMC phenotype.
• Further research into exosome-VSMC interactions can yield novel therapeutic strategies for AS.
• Understanding exosome biology offers promising avenues for cardiovascular disease treatment.
