Endothelial NOS (eNOS), also known as nitric oxide synthase 3 (NOS3) or constitutive NOS (cNOS), is an enzyme that in humans is encoded by the NOS3 gene located in the 7q35-7q36 region of chromosome 7. [5]
Nitric oxide is mediated in mammals by the calcium-calmodulin controlled isoenzymes eNOS (endothelial NOS) and nNOS (neuronal NOS). [2] The inducible isoform, iNOS, involved in immune response, binds calmodulin at physiologically relevant concentrations, and produces NO as an immune defense mechanism, as NO is a free radical with an unpaired ...
Neuronal NOS (NOS1), Endothelial NOS (NOS3), and Inducible NOS macrophage NOS are distinct isoforms. [7] Both the neuronal and the macrophage forms are unusual among oxidative enzymes in requiring several electron donors: flavin adenine dinucleotide (FAD), flavin mononucleotide (FMN), NADPH , and tetrahydrobiopterin .
Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. [1] It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis , among others. [ 2 ]
Nitric oxide, an endothelium-derived relaxing factor (EDRF), is biosynthesized endogenously from L-arginine, oxygen, and NADPH by various nitric oxide synthase (NOS) enzymes. [29] Reduction of inorganic nitrate may also make nitric oxide. [30] One of the main enzymatic targets of nitric oxide is guanylyl cyclase. [31]
The Endothelium-derived relaxing factor (EDRF) is a strong vasodilator produced by cardiac endothelial cells in response to stress signals such as high levels of ADP accumulation or hypoxia. [1] Robert F. Furchgott is widely recognised for this discovery, even going so far as to be a co-recipient of the 1998 Nobel Prize in Medicine with his ...

The endothelium maintains vascular homeostasis through the release of active vasodilators.Although nitric oxide (NO) is recognized as the primary factor at level of arteries, increased evidence for the role of another endothelium-derived vasodilator known as endothelium-derived hyperpolarizing factor (EDHF) has accumulated in the last years.
