Insights
Extracellular vesicles (EVs) are key players in cardiovascular disease (CVD) and atherosclerosis. Understanding their role in lymphatic function may reveal new biomarkers for preventing cardiovascular events.
Area of Science:
- Cardiovascular research
- Biomarker discovery
- Atherosclerosis pathogenesis
Background:
- Cardiovascular disease (CVD) remains a leading cause of mortality, with many events occurring in individuals lacking traditional risk factors.
- Atherosclerosis, the primary cause of CVD, necessitates novel biomarkers for effective prevention strategies.
- Extracellular vesicles (EVs) and lymphatic vessel function are emerging as critical areas of investigation in CVD research.
Purpose of the Study:
- To explore the potential role of extracellular vesicles (EVs) in the interplay between lymphatic function and atherosclerosis.
- To summarize recent findings on the characterization of EVs in the context of lymphatic networks and their implications for atherosclerosis.
- To highlight the need for further research into EV fate within the lymphatic system for cholesterol mobilization and CVD prevention.
Main Methods:
- Literature review of recent studies on extracellular vesicles (EVs).
- Analysis of EV interactions with vascular cells (endothelium, smooth muscle cells, monocytes).
- Investigation of the current understanding of EV behavior within the lymphatic network.
Main Results:
- Extracellular vesicles (EVs) are released by cells and carry complex biological cargo, influencing chronic inflammatory conditions.
- While EV interactions with vascular cells are studied, their fate and function within the lymphatic network remain largely unknown.
- The lymphatic system is crucial for cholesterol mobilization from artery walls, suggesting a potential link with EV activity.
Conclusions:
- Extracellular vesicles (EVs) may represent a critical link between lymphatic function and the development of atherosclerosis.
- Further research into EV characterization and lymphatic transport is essential for identifying new biomarkers and therapeutic targets for CVD.
- Understanding EV dynamics in the lymphatic system could offer novel insights into preventing cardiovascular events in asymptomatic individuals.
Abstract:
Despite significant efforts made to treat cardiovascular disease (CVD), more than half of cardiovascular events still occur in asymptomatic subjects devoid of traditional risk factors. These observations underscore the need for the identification of new biomarkers for the prevention of atherosclerosis, the main underlying cause of CVD. Extracellular vesicles (EVs) and lymphatic vessel function are emerging targets in this context. EVs are small vesicles released by cells upon activation or death that are present in several biological tissues and fluids, including blood and lymph. They interact with surrounding cells to transfer their cargo, and the complexity of their biological content makes these EVs potential key players in several chronic inflammatory settings. Many studies focused on the interaction of EVs with the most well-known players of atherosclerosis such as the vascular endothelium, smooth muscle cells and monocytes. However, the fate of EVs within the lymphatic network, a crucial route in the mobilization of cholesterol out the artery wall, is not known. In this review, we aim to bring forward evidence that EVs could be at the interplay between lymphatic function and atherosclerosis by summarizing the recent findings on the characterization of EVs in this setting.
