Calcitonin gene-related peptide CGRP is a 37-amino-acid neuropeptide belonging to the calcitonin gene peptide superfamily. CGRP is a potent vasodilator with potential therapeutic usefulness for treating vascular-related disease. This peptide is primarily located on C- and Aδ-fibers, which have extensive perivascular presence and a dual sensory-efferent function. Although CGRP has two major isoforms α-CGRP and β-CGRP, the α-CGRP is the isoform related to vascular actions. Release of CGRP from afferent perivascular nerve terminals has been shown to result in vasodilatation, an effect mediated by at least one receptor the CGRP receptor. This receptor is an atypical G-protein coupled receptor GPCR composed of three functional proteins: i the calcitonin receptor-like receptor CRLR; a seven-transmembrane protein, ii the activity-modifying protein type 1 RAMP1, and iii a receptor component protein RCP. Although under physiological conditions, CGRP seems not to play an important role in vascular tone regulation, this peptide has been strongly related as a key player in migraine and other vascular-related disorders e.g., hypertension and preeclampsia. The present review aims at providing an overview on the role of sensory fibers and CGRP release on the modulation of vascular tone.
