Edhf vasodilation
WebSep 21, 2024 · Interestingly, EDHF vasodilation is reduced in complicated pregnancy, such as PE , with consequent increases in PVR, a hallmark of hypertension [29,30,31,32,33]. Therefore, on the basis of our results, we speculate that aspirin may benefit pregnancy with hypertension through lowering peripheral vascular tone by activating EDHF. WebSupporting: 1, Mentioning: 81 - A role for myoendothelial gap junctions (MEGJs) has been proposed in the action of the vasodilator endothelium-derived hyperpolarizing factor (EDHF). EDHF activity varies in disease and during ageing, but little is known of the role of EDHF during development when, in many organ systems, gap junctions are up-regulated. The …
