How does nitric oxide cause vasodilation
WebFeb 1, 2005 · Acetylcholine (ACh) can effect vasodilation by several mechanisms, including activation of endothelial nitric oxide (NO) synthase and prostaglandin (PG) production. In human skin, exogenous ACh increases both skin blood flow (SkBF) and bioavailable NO levels, but the relative increase is much greater in SkBF than NO. This led us to speculate … WebMar 10, 2024 · As a vasodilator, nitric oxide signals the blood vessels to relax, allowing them to expand. This effect allows blood, nutrients, and oxygen to flow freely to every part of …

WebAbstract. Vasodilation is the archetypal function of the endothelial cell and the discovery of paracrine-dependent vasorelaxation by endothelium-derived production of the gaseous mediator nitric oxide (NO) was revolutionary. NO mediates its regulatory vasorelaxing effects through guanilyl cyclase activation. Also, thiol S-nitrosation by NO is ... WebIn the case of vasodilation the Nitric Oxide is originally produced in the neighbouring endothelial cells before diffusing into the smooth muscle cells where it actiavtes sGC and cGMP production. PKG can also have other effects in cells, for example by activating a number of transcription factors which can lead to changes in gene expression ...
