Molecular classification
Epithelial Cell, Cellular Barrier, Signaling Cell
01

Overview

Endothelial cells are specialized squamous epithelial cells that form a single-cell-thick layer lining the interior surface of all blood vessels and lymphatic vessels. They serve as a critical interface between circulating blood/lymph and surrounding tissues, regulating vascular tone, hemostasis, angiogenesis, and immune responses. Dysfunction or damage to endothelial cells is implicated in various diseases, making them an important therapeutic target.

Mechanism of action

Varies depending on the drug. Examples include: Nitric oxide donors promote vasodilation; VEGF inhibitors block angiogenesis; ACE inhibitors affect blood pressure; Monoclonal antibodies block cell adhesion molecules, preventing endothelial cell activation.
