Together with ET-1, ETA, and ETB receptor expression on endothelial cells of ingrown new blood vessels, this points to an involvement of ET-1 and its receptors in corneal angiogenesis. As potent ETA and ETB receptors are available, the endothelin system may represent an additional target for corneal antiangiogenic therapy. PMID: 16160501

ORIGINAL ARTICLE Distortion of KB estimates of endothelin-1 ETA and ETB receptor antagonists in pulmonary arteries: Possible role of an endothelin-1 clearance mechanism James A. Angus1 | Richard J. A. Hughes1 | Christine E. Wright1 Endothelin-1 may therefore have an autocrine or paracrine role in the control of ADH release. Endothelin-1 stimulates atrial natriuretic peptide (ANP) production in vitro and in vivo (Haynes and Webb, 1993a). ANP inhibits generation of endothelin-1 and also attenuates its effects. 1995-12-20 · Those tissues in which endothelin-1 force is mediated primar- ily by endothelin ETA receptors, such as the rat aorta, are clearly susceptible to inhibition by endothelin ETA-selective and -non-selective (endothelin ETA/ N.J.

Endothelin functions through activation of two G protein-coupled receptors, endothelin A and endothelin B receptor (ETA and ETB, respectively). These two subtypes of endothelin receptor are distinguished in the laboratory by the order of their affinity for the three endothelin peptides: the ETA receptor is selective for ET-1, whereas the ETB 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. (NC-IUPHAR), endothelin receptor classified under two types and named as ETA and ETB endothelin receptor [25].

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. 2014-08-28 2019-07-01 Endothelin ETB receptor heterodimerization: beyond the ETA receptor Erika I.

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.

Endothelin receptors, consisting of two subtypes, ETA and ETB, are expressed in various tissues and widely regulate cardiovascular systems. The two receptors show distinct biological characteristics and are involved in different downstream pathways.
