Endothelial dysfunction

Résumé
In vascular diseases, endothelial dysfunction is a systemic pathological state of the endothelium. Along with acting as a semi-permeable membrane, the endothelium is responsible for maintaining vascular tone and regulating oxidative stress by releasing mediators, such as nitric oxide, prostacyclin and endothelin, and controlling local angiotensin-II activity. Research Atherosclerosis Endothelial dysfunction may be involved in the development of atherosclerosis and may predate vascular pathology. Endothelial dysfunction can also lead to increased adherence of monocytes and macrophages, as well as promoting infiltration of LDL in the vessel wall. Dyslipidemia and hypertension are well known to contribute to endothelial dysfunction, and lowering blood pressure and LDL has been shown to improve endothelial function, particularly when lowered with ACE inhibitors, calcium channel blockers, and statins. Nitric oxide Nitric oxide (NO) suppresses p
