Blood vessel wall integrity

Blood vessel wall integrity refers to the structural stability and function of the vessel wall, primarily maintained by interactions among endothelial cells, vascular smooth muscle cells, pericytes, platelets, and extracellular matrix proteins such as collagen and laminin. These cells and matrix proteins create a barrier that regulates blood passage, prevents leakage, and responds dynamically to injury, inflammation, and hemodynamic stress. Disruption of this integrity can result in hemorrhage, edema, or the development of atherosclerotic lesions, and many vascular diseases stem from failure of these protective mechanisms. Several signaling pathways and molecular interactions (e.g., integrins, Notch3, matrix proteins, and platelet-collagen interactions) are essential for the maintenance of blood vessel wall integrity.
