Insights
Cardiac cells communicate using extracellular vesicles, which transfer information like RNA and proteins between cells. These vesicles show promise as potential cardiac therapeutics and biomarkers.
Area of Science:
- Cardiovascular Biology
- Cellular Communication
- Biotechnology
Background:
- The heart relies on intricate cell-cell communication for proper function.
- Intercellular signaling involves direct contact, matrix interactions, and soluble factors.
- Extracellular vesicles (EVs) are increasingly recognized as key mediators of cell communication.
Purpose of the Study:
- To review the role of extracellular vesicles in cardiac communication.
- To explore the potential of EVs as therapeutic agents and biomarkers in cardiology.
Main Methods:
- Literature review of studies on cardiac cell communication and extracellular vesicles.
- Analysis of vesicle content (proteins, RNA, DNA) and their functional implications.
- Discussion of therapeutic and diagnostic applications of cardiac EVs.
Main Results:
- Extracellular vesicles, including apoptotic bodies, microvesicles, and exosomes, facilitate horizontal information transfer between cardiac cells.
- These vesicles carry diverse molecular cargo, influencing myocardial contractility, perfusion, and immune responses.
- EVs represent a novel mechanism for intercellular communication in the heart.
Conclusions:
- Extracellular vesicles play a critical role in maintaining cardiac homeostasis and function.
- Cardiac-derived EVs hold significant potential for developing innovative therapeutic strategies and diagnostic biomarkers.
- Further research into EV biology is crucial for advancing cardiovascular medicine.
Abstract:
The heart is an organ with a complex mixture of well-organized interactions of different cell types that facilitate proper myocardial contractility, sufficient perfusion, balanced myocardial extracellular stiffness, and controlled functioning of the immune system. Several cell types, including cardiomyocytes, endothelial cells, smooth muscle cells, fibroblasts, immune cells, and cardiac-derived stem cells, need a well-controlled communication system to use the complex orchestra of signalling molecules. The intercellular communication includes direct cell-cell contact, cell-matrix interaction, long-range signals, and electrical and extracellular chemical molecules. In addition to the extracellular molecules that cells can use to influence their environment, more and more attention is focused on the release of extracellular membrane vesicles by cells. These vesicles were always thought to be cell debris derivatives, but it appeared that these vesicles are used for horizontal transfer of information between cells, containing proteins, peptides, several classes of RNA molecules, and sometimes DNA. The main populations of released vesicles are classified on their (intra)cellular origin and include apoptotic bodies, microvesicles, and exosomes. Here, we provide an overview on the role of vesicles in cardiac communication and their use as potential therapeutics and biomarkers.
