Cardiac Telocyte-Derived Exosomes and Their Possible Implications in Cardiovascular Pathophysiology

Area of Science:

• Cardiology
• Cell Biology
• Regenerative Medicine

Background:

• Telocytes (TCs) are a distinct cardiac interstitial cell type.
• TCs form a 3D network via telopodes and regulate intercellular signaling.
• TCs interact with cardiomyocytes, stem cells, and immune cells, influencing cardiac homeostasis.

Purpose of the Study:

• To review current research on cardiac telocytes (TCs) and their extracellular vesicles (EVs).
• To explore the role of TCs and EVs in cardiac development, homeostasis, and disease.
• To discuss the therapeutic potential of TCs and TC-derived EVs in cardiac regeneration.

Main Methods:

• Review of existing scientific literature on cardiac telocytes and EVs.
• Analysis of TC morphology, immunophenotype, and signaling mechanisms.
• Examination of TC distribution in normal and diseased hearts.

Main Results:

• Cardiac TCs establish a complex signaling network with various cardiac cell types.
• TC-released EVs (exosomes, ectosomes) mediate paracrine communication.
• TCs are implicated in cardiovascular diseases and hold potential for regenerative therapies.

Conclusions:

• Cardiac TCs are crucial for cardiac stromal compartment integration and homeostasis.
• TC-derived EVs are key mediators of intercellular communication in the heart.
• TC transplantation and TC-derived exosomes represent promising avenues for cardiac regeneration and repair.
