Capillary endothelium integrity (null)

Capillary endothelium integrity denotes the ability of capillary endothelial cells to maintain a selective, semipermeable barrier between blood and tissues. This involves intercellular junctions, the surface glycocalyx, and dynamic cellular responses to mechanical and biochemical signals. Integrity is essential for tissue perfusion, nutrient delivery, waste removal, and protection from inflammatory and pathological insults. Loss of integrity leads to increased permeability, edema, and contributes to the pathogenesis of cardiovascular, inflammatory, infectious, and metabolic diseases. This entry is better described as a "biological function" or "physiological state" rather than a canonical molecular target suitable for drug development. If structured target information is needed, individual molecules contributing to endothelium integrity (e.g., VE-cadherin, claudins, syndecan-1) should be specified instead.
