It is a very potent vasoconstrictor that binds to smooth muscle endothelin receptors, of which there are two subtypes: ETA and ETB receptors. These receptors are

The ligand-receptor signaling pathway is a vertebrate innovation and may reflect the evolution of 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. ET-1 acts on its target tissues through two receptors, endothelin receptor A and B (ETA, ETB). The ETA and ETB receptors are members of the heptahelical G-protein-coupled receptor superfamily, range from 45 to 50 kDa in size (Levin 1995).

As potent ETA and ETB receptors are available, the endothelin system may represent an additional target for corneal antiangiogenic therapy. PMID: 16160501 1994-06-23 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. 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.

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.

The ETA and ETB receptors are members of the heptahelical G-protein-coupled receptor superfamily, range from 45 to 50 kDa in size (Levin 1995). In systemic and pulmonary vessels, ETA receptors are primarily located on the vascular smooth muscle cells Indeed, to prevent endothelin-induced re- ins have potent biological effects, eg, vasoconstriction, sponses, a combined ETA/ETB antagonist such as bosen- vasodilation, and potentiation of the effect of other tan is required, particularly at lower concentrations of vasoconstrictors and mitogenesis.1-4,6,2728 Endothelin endothelin (which are more likely to be achieved in also has been implicated endothelin-1 (ET) for the ET and ET receptors with of A B K i 4.7 nM and 95 nM in human SMC, respectively.

Endothelin-3 – produced in the lungs, gut, and brain. To produce physical effects, endothelins bind to two types of receptors : Endothelin receptor A (ETA or EDNRA) Endothelin receptor B (ETB or EDNRB) ET-1 reduces blood flow and constricts blood vessels in the kidneys through the activation of ETA receptors. Endothelin-1 (ET-1) has been linked to a number of conditions including pulmonary arterial hypertension (PAH).
