Its ligand, endothelin, consists of a family of three potent vasoactive peptides: ET1, ET2, and ET3. 2017-03-01 · The endothelin system is a key target for intervention against glaucomatous neurodegeneration. The endothelin family of peptides and receptors, particularly endothelin-1 (ET-1) and endothelin B (ETB) receptor, has been shown to have neurodegenerative roles in glaucoma. 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 receptor binding and functional studies. There are at least four known endothelin receptors, ET A, ET B1, ET B2 and ET C, all of which are G protein-coupled receptors whose activation result in elevation of intracellular-free calcium, which constricts the smooth muscles of the blood vessels, raising blood pressure, or relaxes the smooth muscles of the blood vessels, lowering blood pressure, among other functions. 2006-06-01 · The endothelin receptors A and B (ETA, ETB) are members of the heptahelical G-protein-coupled receptor superfamily, range from 45 to 50 kDa in size (Levin, 1995) and are encoded by distinct genes located on chromosomes 4 and 13, respectively (Sakurai et al., 1992). Endothelin-1 (ET-1) is synthesized, stored and released in the human heart.

Endothelin mediates its effects via two distinct receptor subtypes ETA and ETB. The present study was designed to investigate the presence of these two receptors in the human trigeminal ganglion. METHODS: Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to show the presence of mRNA encoding ETA and ETB receptors in the human trigeminal ganglion. 2006-11-01 Endothelin (ET) receptors involved in ET-1-induced responses of the longitudinal muscle of the isolated guinea pig ileum were studied. ET-1 caused concentration-dependent contractions, while ET-3 and selective ETB-receptor agonists, IRL1620 and sarafotoxin 6c (S6c), showed little or no effect.

There are at least four type known, ETA, ETB1, ETB2 and ETC. ETA is a subtype for vasoconstriction. These receptors are found in the smooth muscle tissue of blood vessels, and binding of endothelin to ETA increases Two specific receptors for the endothelins have been isolated by in vitro expression of cloned human cDNA.

As potent ETA and ETB receptors are available, the endothelin system may represent an additional target for corneal antiangiogenic therapy.

Endothelin ETA and ETB receptor expression in the human

The ETA receptor antagonist, BQ123, competitively antagonized (pA2 6.93) the contraction of RTA produced by ET-1, but had no effect (at 10 microM) on the contractile effects of either ET-1, ET-3 or [Ala1,3,11,15]ET-1 in RJV. 4. These data suggest that both ETA and ETB receptors can mediate vascular smooth muscle contraction. BACKGROUND. Endothelin (ET)-1 has potent vascular effects. Two endothelin receptors have been cloned, namely, the ETA receptor, which preferentially binds ET-1, and the ETB receptor, which equally binds ET-1 and ET-3 and preferentially sarafotoxin S6c. We have investigated the endothelin receptor subtypes mediating contraction in isolated preparations of human saphenous vein. Endothelin-1 (EC50: 17.8 nM), endothelin-3 (EC50: 82.3 nM) and the endothelin ETB receptor-selective agonists, [Ala1,3,11,15]endothelin-1 (EC50: 63 nM) and sarafotoxin S6c (EC50: 0.75 nM) all produced concentration-dependent contractions of human saphenous vein ARTICLE Distribution of Endothelin Receptor Subtypes ET A and ET B in the Rat Kidney Martina Wendel, Lilla Knels, Wolfgang Kummer, and Thea Koch Department of Anesthesiology and Intensive Care Medicine, University Hospital, Dresden, Germany (MW,LK,TK), and Background and Purpose-Elevated levels of endothelin 1 (ET 1) have been reported in cerebral ischemia A role for ET may prove more important if the vascular receptors were changed We addressed whether there is any change in ET receptor expression in cerebral ischemia Methods-The right middle cerebral artery (MCA) was occluded in male Wistar rats for 2 hours with the intraluminal filament Adner M, Cardell L-O, Sjöberg T, Ottosson A, Edvinsson L.
