Epicardial Adipocytes in Cardiac Pathology and Healing

Area of Science:

• Cardiovascular Science
• Adipose Tissue Biology
• Regenerative Medicine

Background:

• Epicardial adipose tissue (EAT), located adjacent to the myocardium, has unique characteristics distinct from other fat depots.
• EAT's transcriptome and secretome differ significantly, influencing cardiac function and disease development.

Purpose of the Study:

• To comprehensively review the mechanisms by which epicardial adipose tissue (EAT) influences cardiac function and regeneration.
• To explore the dual role of EAT in both protecting the heart and contributing to cardiovascular diseases (CVD).

Main Methods:

• Literature review synthesizing current research on epicardial adipose tissue (EAT).
• Analysis of EAT's physiological functions, including thermogenesis and fatty acid oxidation.
• Examination of EAT's secretome and its impact on myocardial and coronary vessels.

Main Results:

• EAT exhibits protective functions via thermogenic activity and fatty acid oxidation.
• EAT releases pro-inflammatory mediators contributing to cardiovascular disease (CVD) progression.
• EAT-derived mesenchymal stromal cells show potential for cardiac regeneration.

Conclusions:

• Epicardial adipose tissue (EAT) has a complex, multifaceted role in cardiovascular health and disease.
• A thorough understanding of EAT is crucial for developing novel pharmacological and therapeutic strategies for cardiovascular disease (CVD) management and cardiac regeneration.
