These three isopeptides mediate their biological functions by ET α and ET β receptor subtypes [ 169, 170 ]. The ET α is located on vascular smooth muscle cells and ET β on vascular endothelial cells.

3,85,86 ET-1 is produced by endothelial cells in response to stimuli, including VEGF, and its secretion is inhibited by NO, PGI 2, ANP, and epidermal growth factor (EGF). 85,87,88 ET-1 mediates its effects through ET A R and ET B R, both of which are G-protein–coupled receptors. Endothelin-1 (ET-1), a potent vasoconstrictor secreted by vascular endothelial cells, has been implicated in the pathophysiology of numerous cardiovascular diseases, yet the direct impact of ET-1 on vascular function remains unclear. Therefore, in seven young (23 ± 1 yr) healthy subjects, we investi … The endothelin (ET) system consists of three peptide ligands (ET-1, ET-2 and ET-3) and two G-protein-coupled receptors, ET (A) and ET (B).

The protein encoded by this gene is proteolytically processed to release a secreted peptide termed endothelin 1. Endothelin 1 is one of three isoforms of human endothelin. Endothelins are peptides with receptors and effects in many body organs. Endothelin constricts blood vessels and raises blood pressure. The endothelins are normally kept in balance by other mechanisms, but when overexpressed, they contribute to high blood pressure, heart disease, and potentially other diseases. Endothelins are 21-amino acid vasoconstricting peptides produced primarily in the endothelium having a key role in vascular homeostasis. Endothelins are implicated in vascular diseases of Endothelin-1 (ET-1) is the most potent endogenous vasoconstrictor and is strongly implicated in the pathogenesis of hypertension and endothelial dysfunction.

Endothelin-1 Impairs Alveolar Epithelial Function via Endothelial ET B Receptor Alejandro P. Comellas 1, Arturo Briva2, Laura A. Dada 1, Maria L. Butti , Humberto E. Trejo , Cecilia Yshii , Zaher 2006-03-27 · Background As prolonged hyperoxia induces extensive lung tissue damage, we set out to investigate the involvement of endothelin-1 (ET-1) receptors in these adverse changes. Methods Experiments were performed on four groups of mice: control animals kept in room air and a group of mice exposed to hyperoxia for 60 h were not subjected to ET-1 receptor blockade, whereas the dual ETA/ETB-receptor In summary, ET-1 induces an EMV phenotype that adversely affects endothelial cell function. ET-1-generated EMVs may contribute to the atherogenic effect of ET-1.
