Endothelin in the pulmonary circulation with special reference to hypoxic pulmonary vasoconstriction

Recently endothelin receptor C (ETRC) was discovered, however, its functions and distribution still remain unclear. The effects mediated by ET-1 via ETRA are vasoconstriction, bronchoconstriction and secretion of aldosterone.

Endothelin and prostanoids cause vasoconstriction in placental arteries, while nitric oxide causes vasodilation. endothelin may be engaged in the pathogenesis of myocardial fibrosis (Kazzam 1997). A high incidence. of cold- and stress induced myocardial reversible hypoxic pulmonary vasoconstriction in the pig without and with dual endothelin receptor blockade, Acta Physiol., 206(3):178-94.

Endothelin vasoconstriction

(a) The time courses of 0.1nmol/l Ang II– and ET-1–induced vasoconstriction are shown as mean values±s.e.m. (n¼5 for Ang II and n¼8 for ET-1), with the thin lines depicting the s.e.m. 2011-01-26 · Background Reduced uteroplacental perfusion, the initiating event in preeclampsia, is associated with enhanced endothelin-1 (ET-1) production which feeds the vasoconstriction of uterine artery. Whether the treatments of preeclampsia were effective on ET-1 induced contraction and could reverse placental ischemia is the question addressed in this study. We investigated the effect of endothelin on the renal microvasculature, and update recent findings on endothelin in the regulation of renal hemodynamics.

vasoconstrictor and pressor substance known. Endothelin-1 is a 21-amino-acid endothelium- derived peptide causing uniquely sustained vasoconstriction.

Endothelin-1 (ET-1) is a 21 amino acid peptide that is produced by the vascular endothelium (click here for details). It is a very potent vasoconstrictor that binds One such vasoconstrictor was described initially by Hickey et al.1.

Vascular hindrance, a calculation of blood pressure divided by blood flow and viscosity, was raised by about 20%, suggesting marked vasoconstriction of

Although endothelin-3 caused significantly less forearm vasoconstriction than endothelin-1 at low doses, vasoconstriction was similar to the two isopeptides at the highest dose (60 pmol/min). Endothelin-3 caused transient forearm vasodilatation at this dose, whereas endothelin-1 showed only a nonsignificant trend toward causing early vasodilatation. Upregulation of endothelin ETB receptor-mediated vasoconstriction in rat coronary artery after organ culture Eskesen, K and Edvinsson, Lars LU () In European Journal of Pharmacology 539 (3). p.192-194 Recently endothelin receptor C (ETRC) was discovered, however, its functions and distribution still remain unclear. The effects mediated by ET-1 via ETRA are vasoconstriction, bronchoconstriction and secretion of aldosterone. The endothelin-1 vasoconstrictor pathway contributes to age-related elevations in resting peripheral vascular tone primarily through activation of the endothelin subtype A (ET (A)) receptor. However, the regulatory influence of ET (A)-mediated vasoconstriction during exercise in the elderly is unknown.
