It is synthesized and released from endothelial cells and acts upon two receptor subtypes designated as ETA and ETB. Endothelin-1 promoted fibroblast synthesis of collagen types I and III, but not fibronectin, by a mechanism dependent upon both ETA and ETB receptors. Conversely, endothelin-1 inhibited both 1 The aim of the present study was to investigate the role of endothelin ETA and ETB receptors in the regulation of intrarenal blood flow and oxygen tension in normotensive Sprague‐Dawley rats. 2 Thiobutabarbital anaesthetized rats were divided into four groups (n = 6–9 per group): (i) saline (4 mL/kg per h); (ii) BQ123; (iii) BQ788; and (iv) BQ123 + BQ788.

Eta etb endothelin

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.

The goal of this study was to characterize the role of Endothelin (ET) type B receptors (ETB) on vascular function in healthy and diseased conditions and demonstrate how it affects the pharmacological activity of ET receptor antagonists (ERAs). Endothelin functions through activation of two G protein-coupled receptors, endothelin A and endothelin B receptor (ETA and ETB, respectively).

Endothelin-1 has dual vasoactive effects, mediating vasoconstriction via ETA receptor activation of vascular smooth muscle cells and vasorelaxation via ETB 

In this study, we wanted to verify whether ET-1 plays a role in the survival of hVECs via the activation of its receptors ET A and (or) ET B (ET A R and ET B R, respectively). 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. Hence, to evaluate the ETA and ETB receptors on th … 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.

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.

Endothelin‐1 (ET‐1) levels have been shown to be increased during myocardial ischaemia in humans (Miyauchi et al., 1989; Yasuda et al., 1990), pigs (Wang et al., 1995) and rabbits (Vitola et al., 1996).Exogenous administration of ET‐1 results in myocardial ischaemia in dogs through its potent coronary vasoconstrictor ability (Salvati et al., 1991) and causes ventricular 1995-01-01 Marc Iglarz, Pauline Steiner, Daniel Wanner, Markus Rey, Patrick Hess, Martine Clozel, Vascular Effects of Endothelin Receptor Antagonists Depends on Their Selectivity for ETA Versus ETB Receptors and on the Functionality of Endothelial ETB Receptors, Journal of Cardiovascular Pharmacology, 10.1097/FJC.0000000000000283, 66, 4, (332-337), (2015).
