Definitions related to nesiritide:
-
A recombinant version of the cardiac neurohormone, human B-type natriuretic peptide (hBNP) produced by the ventricular myocardium. Nesiritide binds to natriuretic peptide receptors on vascular smooth muscle and endothelial cells, through which it triggers guanylate cyclase dependent signal transduction resulting in increase of intracellular concentrations of cGMP. This leads to smooth muscle cell relaxation causing arterial and venous dilatation.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(natriuretic peptide, brain) A PEPTIDE that is secreted by the BRAIN and the HEART ATRIA, stored mainly in cardiac ventricular MYOCARDIUM. It can cause NATRIURESIS; DIURESIS; VASODILATION; and inhibits secretion of RENIN and ALDOSTERONE. It improves heart function. It contains 32 AMINO ACIDS.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
