endothelialmem
Endothelialmem is a term used to refer to the plasma membrane of endothelial cells, which line the interior surface of blood vessels. This membrane forms a dynamic barrier between circulating blood and underlying tissues and participates in selective solute flux, signal transduction, and intercellular communication. The endothelial membrane consists of a phospholipid bilayer rich in cholesterol and an outer leaflet enriched with glycolipids. It contains an array of membrane proteins such as receptors (VEGFR, ICAM-1, VCAM-1, thrombomodulin), transporters (GLUT1, aquaporin-1), ion channels, and components of cell junctions such as VE-cadherin. The surface is coated by the glycocalyx, a carbohydrate-rich layer that modulates permeability and interaction with blood components.
Functions include regulation of vascular permeability, mechanotransduction in response to shear stress, leukocyte recruitment during inflammation,
Clinical relevance: Endothelialmem dysfunction contributes to edema, atherosclerosis, hypertension, sepsis, and diabetic microvascular complications. Changes in
Research and therapeutics: studies examine lipid composition, protein interactions, and glycocalyx integrity; endothelial-targeted therapies (e.g., anti-angiogenic
