Furchgott and Zawadski, in 1980, first postulated that the endothelial layer of blood vessels produced a putative vasorelaxing factor, which, for several years, was termed endothelium‐derived relaxing factor (EDRF). Its role in vascular disease has been intensively investigated and further elucidated over the past two decades. NO regulates the degree of contraction of vascular smooth muscle cells mainly by stimulating soluble guanylyl cyclase (sGC) to produce cyclic guanosine monophosphate (cGMP), although cGMP-independent signaling [S-nitrosylation of target proteins, activation of sarco/endoplasmic reticulum calcium ATPase (SERCA) or production of cyclic inosine monophosphate (cIMP)] also can be involved.

As the first discovered gaseous signaling molecule, nitric oxide (NO) affects a number of cellular processes, including those involving vascular cells. Although estrogen is known to stimulate nitric oxide synthesis in vascular endothelium, the molecular mechanisms responsible for this effect remain to be elucidated. It helps modulate vascular tone, insulin secretion, airway tone, and peristalsis, and is involved in angiogenesis and neural development. Int J Impot Res. Vascular nitric oxide: Beyond eNOS.

Dynamic association of nitric oxide downstream signaling molecules with endothelial caveolin-1 in rat aorta. Additionally, the increased risk of death with diseases that have underlying endothelial dysfunction suggest that endothelial NOS-derived nitric oxide could be the main defence mechanism. When taken orally, however, much of the arginine never reaches the endothelium. Epub 2014 May 16. Journal of Pharmacological Sciences 129 (2015) 83e94. However, the effects of food-derived arginine on vascular function have not been systematically interrogated in studies; instead, clinical research has evaluated high doses of arginine in supplement form.
