Endothelin-1 has been shown to be associated with greater myocardial ischemia and reperfusion injury in which oxidative stress plays a key role. The efficacy of bosentan, a mixed ETA-ETB Endothelins (ETs) are a family of novel regulatory peptides and various lines of evidence suggest an important role for ETs in regulating pulmonary function. Two receptors for endothelin, ETA and ETB, have been found in the human lung, and according to recent studies a non-ETA receptor seems to mediate the contraction of large sized human bronchi.

In human vasculature, ETA receptors predominate on the smooth muscle cells, and a low density of ETB receptors (<15%) is also present on these cells. In vitro studies show a discrete participation of ETB The endothelins comprise three structurally similar 21-amino acid peptides.

2014-08-28 2019-07-01 Endothelin ETB receptor heterodimerization: beyond the ETA receptor Erika I. Boesen1 The idea that endothelin ETA and ETB receptors may form homodimers and heterodimers has gained increasing interest in recent years. The existence of such interactions between endothelin receptors has the potential to explain some puzzling results from dysfunction is currently not known, but studies suggest a potential role of endothelin in mediating the insufficiency. Accordingly, the role of endothelin was assessed using the nonpeptidyl, dual ETA/ETB endothelin antagonist L-754,142 in a model of renal insufficiency in the anesthetized dog induced by 2017-05-01 1992-11-01 E.M.

We therefore investigated the function of ET B receptors in vivo in human forearm resistance and hand capacitance vessels using endothelin-1 Abstract Background Primary open angle glaucoma is a heterogeneous group of optic neuropathies that results in optic nerve degeneration and a loss of retinal ganglion cells (RGCs) ultimately causing blindness if allowed to progress. Elevation of intraocular pressure (IOP) is the most attributable risk factor for developing glaucoma and lowering of IOP is currently the only available therapy 2013-02-25 Endothelin-1 (ET-1) is synthesized, stored and released in the human heart.
