Nitric Oxide: Orchestrator of Endothelium-Dependent Responses.
Félétou M, Köhler R, Vanhoutte P.M.. Nitric Oxide: Orchestrator of Endothelium-Dependent Responses.. Ann. Med.. 2012, Vol. 44(7), p. 694-2012.
Abstract The present review first summarizes the complex chain of events, in endothelial and vascular smooth muscle cells, that leads to endothelium-dependent relaxations (vasodilatations) due to the generation of nitric oxide (NO) by endothelial nitric oxide synthase (eNOS) and how therapeutic interventions may improve the bioavailability of NO and thus prevent/cure endothelial dysfunction. Then, the role of other endothelium-derived mediators (endothelium-derived hyperpolarizing (EDHF) and contracting (EDCF) factors, endothelin-1) and signals (myoendothelial coupling) is summarized also, with special emphasis on their interaction(s) with the NO pathway, which make the latter not only a major mediator but also a key regulator of endothelium-dependent responses.
