Vascular endothelium (specifically: vascular endothelial cell membrane) (None commonly used; sometimes abbreviated as EC for endothelial cell in scientific literature)

The vascular endothelium cell membrane is the plasma membrane of the endothelial cells that line the interior of the entire cardiovascular system, forming a dynamic interface between blood and tissue. It consists of a phospholipid bilayer embedded with various proteins, including receptors, enzymes, transporters, and adhesion molecules that collectively regulate vascular tone, permeability, hemostasis, immune cell trafficking, inflammation, and angiogenesis. The membrane features specialized structures such as tight junctions and a glycocalyx layer, which contribute to its barrier function and molecular selectivity. While the membrane itself is not a drug target, its associated proteins and pathways are of vast pharmacological and diagnostic importance.

Not applicable; instead, mechanisms involve modulation of membrane-embedded proteins to affect function (e.g., inhibition of angiogenesis via VEGF receptor antagonism, modulation of permeability via anti-inflammatory agents)
