Intracellular pathways of calcitonin gene‐related peptide‐induced relaxation of human coronary arteries: A key role for Gβγ subunit instead of cAMP

Calcitonin gene-related peptide (CGRP) is a potent vasodilator. While its signalling is assumed to be mediated via increases in cAMP, this study focused on elucidating the actual intracellular signalling pathways involved in CGRP-induced relaxation of human isolated coronary arteries (HCA).
