WebThe vasodilatory peptides calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP-38), as well as the neurotransmitter nitric oxide (NO), are all potent vasodilators implicated in migraine pathophysiology ( Brain et al., 1985; Moncada et al., 1991; Messlinger et al., 2012; Kaiser and Russo, 2013; … WebCGRP has been implicated in the pathophysiology of migraine: infusion of CGRP can trigger a migraine attack, CGRP concentrations are raised in the external jugular venous blood during migraine attacks, and triptans block the release of CGRP. , On the basis of this and other evidence, CGRP antagonists were identified as candidate acute migraine …
The effects of CGRP in vascular tissue - ScienceDirect
WebThe effects of CGRP, SP, and neurokinin A (NKA) have been examined on isolated cerebral arteries in vitro. Different CGRP analogues induced a strong relaxation with no difference in I max (85–96%) or pD 2 values (8.65–9.12). NKA induced a stronger relaxation than SP (I max 33% and 13%, respectively). WebFeb 3, 2010 · Under some pathophysiological conditions, CGRP also mediates the antihypertensive effect of rutaecarpine [19,20,21,22]. In vitro, rutaecarpine (10 or 30 μM) inhibits vasoconstriction in presensitized guinea pig thoracic aorta challenged with antigen, which are significantly attenuated by CGRP 8-37 . german numbers up to 100
