Extracellular vesicles (EVs) regulate endothelial cells (ECs), impacting tumor angiogenesis and vascular dysfunction in atherosclerosis. These vesicles carry various molecules, mediating cell-cell communication in disease.
Area of Science:
- Cell Biology
- Molecular Biology
- Pathophysiology
Background:
- Intercellular communication is vital for tissue homeostasis.
- Extracellular vesicles (EVs) mediate cell-cell communication by transferring molecular cargo.
- Endothelial cells (ECs) are key targets of EV-mediated regulation.
Purpose of the Study:
- To review the role of exosomes in regulating ECs within the tumor microenvironment.
- To discuss the involvement of exosomes in vascular dysfunction and atherosclerosis.
- To survey the molecular mechanisms and cargoes responsible for these regulatory effects.
Main Methods:
- Literature review and evidence synthesis.
- Analysis of exosomal cargoes and their functions.
- Investigation of molecular mechanisms in EC regulation.
Main Results:
- Cancer cell-derived EVs influence ECs, promoting tumor angiogenesis and cancer progression.
- Exosomes play a significant role in EC regulation within the tumor microenvironment.
- EVs contribute to vascular dysfunction and atherosclerosis development.
Conclusions:
- Exosomes are critical mediators of intercellular communication affecting ECs in cancer and vascular diseases.
- Understanding exosome function and cargo is crucial for therapeutic strategies.
- EVs represent key players in both physiological and pathological intercellular signaling.
