INTRODUCTION Understanding of the function of endothelin-1 in the pathophysiology of endothelial disease, in particular pulmonary arterial hypertension

The overproduction of endothelin in the lung can cause pulmonary arterial hypertension (PAH). Thus, endothelin receptor antagonists (ERAs) have been approved for the treatment of this disease [1]. Beyond hypertensive pathologies, the endothelin axis has pleiotropic functions associated with fundamental cellular processes, including cell Three isoforms of human endothelin have been identified: endothelin-1, -2, and -3. Endothelin-1 is a potent, 21-amino acid vasoconstrictor peptide produced by vascular endothelial cells.

De följdes Endothelins are peptides with receptors and effects in many body organs. Endothelin constricts blood vessels and raises blood pressure. The endothelins are normally kept in balance by other mechanisms, but when overexpressed, they contribute to high blood pressure, heart disease, and potentially other diseases. Endothelins are 21-amino acid vasoconstricting peptides produced primarily in the endothelium having a key role in vascular homeostasis. Endothelins are implicated in vascular diseases of The endothelin (ET) system consists of three peptide ligands (ET-1, ET-2 and ET-3) and two G-protein-coupled receptors, ET (A) and ET (B). In the cardiovascular system, ETs, particularly ET-1, are expressed in smooth muscle cells, cardiomyocytes, fibroblasts, and notably in vascular endothelial cells.

These studies have identified key roles for the endothelin isoforms and new therapeutic targets in development, fluid-electrolyte homeostasis, and cardiovascular and neuronal function. For the future, novel pharmacological strategies are emerging via small molecule epigenetic modulators, biologicals such as ETB monoclonal antibodies and the potential of signaling pathway biased agonists and Figure 1: Components of the endothelin system. Prepro-endothelins are formed following transcription and translation from prepro-endothelin mRNA and are subsequently processed by furin-like proteases to form big-ET intermediates that are further cleaved to three physiologically active endothelin peptides by endothelin-converting enzymes and other enzymes. Endothelin is an important modulator of renal function via its binding to abundant receptors in renal tissue and by the ability of renal endothelial and epithelial cells to synthesize and release endothelin.

The rank order of binding affinities for ET-A is: ET1 > ET2 >> ET3.

Nonspecific blockade of endothelin receptors lowers BP in models of volume-expanded hypertension. The role of endothelin in human essential hypertension is unclear. The endothelin (ET) system consists of three peptide ligands (ET-1, ET-2 and ET-3) and two G-protein-coupled receptors, ET (A) and ET (B).

ERAs work by reducing the amount of a substance called endothelin in the blood. Endothelin is made in the layer of cells that line the heart and blood vessels. It causes the blood vessels to constrict (become narrower). In people with PH the body produces too much endothelin.

2011-06-01 · Endothelin-1. The endothelins constitute a super family of peptides that are structurally similar to sarafotoxins found in snake venom ().There are three separately encoded isoforms (ET-1, ET-2, and ET-3), and although all isoforms are involved in vascular function (reviewed in Ref. 8), ET-1 is the dominant isoform in the cardiovascular system and is therefore the most often studied.

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. These studies have identified key roles for the endothelin isoforms and new therapeutic targets in development, fluid-electrolyte homeostasis, and cardiovascular and neuronal function.
