WebFeb 1, 2007 · Although the acronym EDHF is universally used to describe the NO- and prostacyclin-independent relaxation, the actual mechanism that underlies the response might not necessarily involve a diffusible ‘factor’ as such. Alternatively, it might reflect the synergistic action of both contact-mediated and diffusible mechanisms [5]. WebEndothelium-derived relaxing factor (EDRF) is an unstable chemical substance released from vascular endothelial cells, which line the inner surface of blood vessels. EDRF …

Opening of IKCa and SKCa in endothelial cells underlies the classic EDHF pathway and promotes NO production. Smooth muscle BKCa provides a negative feedback mechanism opposing vasoconstriction and is an effector of NO and EDHF.

WebThis function is achieved by the release of nitric oxide (NO), prostacyclin (PGI2), and the endothelium-derived hyperpolarizing factor (EDHF) [ 1 ]. Of these autacoids, NO predominates in large conducting arteries, whereas the importance of EDHF increases as the size of the arteries decreases [ 2 – 4 ]. darpa neurotechnologyWebThese data suggest that NO protects against the development of hypertension during early-stage diabetes in mice, even in the absence of eNOS.
