Calcitonin Gene-Related Peptide (CGRP)
Calcitonin gene-related peptide (CGRP) is a 37 amino acid vasoactive neuropeptide that is widely distributed in central and peripheral nervous systems in mammals. CGRP was discovered in 1982 by molecular cloning of calcitonin (CT) gene. CGRP-specific mRNA appears to predominate in the hypothalamus while CT mRNA predominates in the thyroid. CGRP has an amphiphilic α-helical secondary structure i...
متن کاملDevelopment and potential of non-peptide antagonists for calcitonin-gene-related peptide (CGRP) receptors: evidence for CGRP receptor heterogeneity.
Calcitonin-gene-related peptide (CGRP) is a 37-amino-acid vasodilatory peptide, of which two isoforms, alpha CGRP and beta CGRP, have been described. The use of C-terminal fragments of CGRP peptide, such as human alpha CGRP-(8-37), has led to the pharmacological subdivision of CGRP receptors into CGRP-1 [high potency for binding of human alpha CGRP-(8-37)] and CGRP-2 (lower potency) receptors. ...
متن کاملCalcitonin gene-related peptide receptor antagonist human CGRP-(8-37).
From this study, we predicted that the human calcitonin gene-related peptide (hCGRP) fragment hCGRP-(8-37) would be a selective antagonist for CGRP receptors but an agonist for calcitonin (CT) receptors. In rat liver plasma membrane, where CGRP receptors predominate and CT appears to act through these receptors, hCGRP-(8-37) dose dependently displaced 125I-[Tyr0]rat CGRP binding. However, hCGRP...
متن کاملCalcitonin gene related peptide (CGRP)-provoked migraine-like attacks.
In this issue of Cephalalgia, Dr Jakob Moller Hansen and his colleagues report a series of very interesting experiments in which they successfully induced migraine-like attacks in patients with migraine with aura via infusion of calcitonin gene related peptide (CGRP). This work echoes similar experiments carried out by the Copenhagen group using the nitric oxide donor, glycerol trinitrate (GTN)...
متن کاملImmature osteoblastic MG63 cells possess two calcitonin gene-related peptide receptor subtypes that respond differently to [Cys(Acm)(2,7)] calcitonin gene-related peptide and CGRP(8-37).
Calcitonin gene-related peptide (CGRP) is clearly an anabolic factor in skeletal tissue, but the distribution of CGRP receptor (CGRPR) subtypes in osteoblastic cells is poorly understood. We previously demonstrated that the CGRPR expressed in osteoblastic MG63 cells does not match exactly the known characteristics of the classic subtype 1 receptor (CGRPR1). The aim of the present study was to f...
