What is the Origin of Endothelial Function?

The term combines endothelium, the specialized cell layer, and function, referring to its physiological role. Recognition of the endothelium as a metabolically active organ, rather than a passive lining, emerged in the late 20th century with the discovery of endothelium-derived relaxing factor, later identified as nitric oxide.

What is the Mechanism of Endothelial Function?

Healthy endothelial function is primarily mediated by the regulated production and release of vasoactive substances, most notably nitric oxide (NO), a potent vasodilator. Nitric oxide promotes vascular smooth muscle relaxation, inhibits platelet aggregation, and suppresses inflammatory responses. Hormones, including estrogen and testosterone, exert direct protective effects on the endothelium, supporting its capacity to produce NO and maintain optimal vascular tone and integrity throughout the circulatory system.

Endothelial Function

Meaning

The physiological performance of the endothelium, which is the single layer of cells lining the interior surface of blood vessels, including arteries, veins, and capillaries. Optimal endothelial function is essential for maintaining vascular homeostasis, regulating blood flow, and preventing the formation of atherosclerotic plaques. Dysfunction in this layer is an early and significant indicator of cardiovascular risk.
