Calcitonin gene-related peptide-containing pathways in the rat forebrain

The mechanism of calcitonin gene-related peptide-containing nerve innervation.

Calcitonin gene-related peptide (CGRP) is a major neurotransmitter and CGRP-containing primary sensory neurons play an important role in nociception and potent vasodilation. CGRP-containing nerves in mesenteric arteries are decreased in pathological animal models (hypertension, diabetes, and atherosclerosis). In apolipoprotein E–knockout mice, which have atherosclerosis and peripheral sen...

Comparison between Brain Natriuretic Peptide and Calcitonin Gene Related Peptide in Children with Dilated Cardiomyopathy

Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction. This study was performed to determine the level of Calcitonin Gene Related Peptide (CGRP) and Brain Natriuretic Peptide (BNP) in children with dilated cardiomyopathy and controls and comparison of these two biomarkers in patients. Materials and Methods: This case-control study was...

Calcitonin gene-related peptide in noradrenergic transmission in rat hypothalamus.

In the present study, we examined the regulatory mechanisms of calcitonin gene-related peptide on norepinephrine release in rat hypothalamus. Calcitonin gene-related peptide inhibited the stimulation-evoked norepinephrine release from hypothalamic slices of Sprague-Dawley rats in a dose-dependent manner, although the peptide did not affect basal release of norepinephrine. The blockade of the al...

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...
