Vascular endothelial cell (EC)

Vascular endothelial cells line the inner surface of blood vessels and play a critical role in maintaining vascular barrier integrity, regulating vascular permeability, inflammation, thrombosis, and angiogenesis[3][6][7]. "Vascular endothelial cell protection" refers to strategies and therapeutic interventions aimed at preventing endothelial cell injury, maintaining cell survival, and preserving endothelial function in the face of cardiovascular, metabolic, and inflammatory diseases[1][3][5]. Molecular targets involved in endothelial cell protection include enzymes (like eNOS), cell surface receptors (e.g., VEGF receptor), and mediators of cell survival, but the phrase itself is not a single drug target, receptor, gene, or protein[1][3][6]. Pharmacological approaches to vascular endothelial cell protection encompass drugs that support endothelial health by reducing oxidative stress, modulating inflammation, promoting endothelial survival, and preventing age-related endothelial dysfunction[1][5]. Endothelial dysfunction contributes to a wide spectrum of vascular diseases, and restoring or preserving endothelial health is an important therapeutic goal, not a druggable target per se[3][6].
