Human vascular endothelial cells (HVEC)

Human vascular endothelial cells (ECs) form the continuous, one-cell-thick internal lining of all blood vessels, known as the endothelium. This cellular layer serves as a critical interface between the circulating blood and the vessel wall, functioning as a dynamic organ that regulates vascular tone, fluid homeostasis, and the recruitment of inflammatory cells (Gimbrone & García-Cardeña, 2016). Endothelial cells maintain vascular health by producing vasodilators like nitric oxide and preventing inappropriate coagulation; however, their dysfunction is a primary driver of cardiovascular diseases such as atherosclerosis and hypertension (Pober & Sessa, 2007). In oncology, these cells are the targets of anti-angiogenic therapies, which aim to disrupt the blood supply to tumors by inhibiting endothelial proliferation and migration (Ferrara & Adamis, 2016). While "Human vascular endothelial cells" refers to a cell type rather than a single molecular target, they express a multitude of clinically significant receptors and enzymes that are central to modern pharmacology. These cells also play a role in the blood-brain barrier and the regulation of immune responses through the expression of adhesion molecules (Pober & Sessa, 2007). Pharmacological intervention often focuses on restoring endothelial function or inhibiting pathological endothelial growth in conditions like wet macular degeneration (Ferrara & Adamis, 2016).

Drugs targeting the endothelium typically act by binding to specific surface receptors (e.g., VEGF receptors), inhibiting enzymes within the cells (e.g., Angiotensin-converting enzyme), or modulating the release of paracrine factors like nitric oxide to alter vascular permeability and tone (Ferrara & Adamis, 2016; Pober & Sessa, 2007).
