Swedish University dissertations (essays) about ENDOTHELIN. exerts its effect through two receptors; the endothelin type A (ETA) and type B (ETB) receptor.

Endothelin-1 (ET-1) is a potent mitogen and modulator of vascular tone. It is synthesized and released from endothelial cells and acts upon two receptor subtypes designated as ETA and ETB.

Endothelin-1 (ET-1) has been linked to a number of conditions including pulmonary arterial hypertension (PAH). ET-1 acts via 2 receptors, ETA and ETB. The ET-1 receptor blockers bosentan and sitaxsentan have been shown to be beneficial in patients with PAH. Bosentan blocks both ETA and ETB receptors. 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.

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-1 (ET-1) has been linked to a number of conditions including pulmonary arterial hypertension (PAH). ET-1 acts via 2 receptors, ETA and ETB. The ET-1 receptor blockers bosentan and sitaxsentan have been shown to be beneficial in patients with PAH. Bosentan blocks both ETA and ETB receptors. Our previous work showed the presence of endothelin-1 (ET-1) receptors, ET A and ET B, in human vascular endothelial cells (hVECs). 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).

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. On release, ET-1 has the potential to activate specific receptors in a paracrine manner to modify heart function directly. Two binding sites corresponding to endothelin ETA and ETB receptors are localized to human heart.

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.

The existence of such interactions between endothelin receptors has the potential to explain some puzzling results from receptor binding and functional studies. The functional importance of endothelin ET A and ET B receptors in selected arterial and venous smooth muscle preparations was characterized. Endothelin-1 induced force in the saphenous and jugular veins is normally mediated by endothelin ET B -like receptors.

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.

The endothelins comprise three structurally similar 21-amino acid peptides. Endothelin-1 and -2 activate two G-protein coupled receptors, ETA and ETB, with equal affinity, whereas endothelin-3 has a lower affinity for the ETA subtype. Genes encoding the peptides are present only among vertebrates. The ligand-receptor signaling pathway is a vertebrate innovation and may reflect the evolution of

Endothelin-1 has been shown to be associated with greater myocardial ischemia and reperfusion injury in which oxidative stress plays a key role. The efficacy of bosentan, a mixed ETA-ETB Endothelins (ETs) are a family of novel regulatory peptides and various lines of evidence suggest an important role for ETs in regulating pulmonary function. Two receptors for endothelin, ETA and ETB, have been found in the human lung, and according to recent studies a non-ETA receptor seems to mediate the contraction of large sized human bronchi. E.M. Motta, J.G. Chichorro, P. D’Orléans-Juste, G.A. Rae, Roles of endothelin [31] H. Yamamoto, T. Kawamata, K. Omote, A.

Our previous work showed the presence of endothelin-1 (ET-1) receptors, ET A and ET B, in human vascular endothelial cells (hVECs). 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). 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). 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].
