Involvement of CGRP receptor RAMP1 in cluster headache: A Swedish case-control study
Background: Increased levels of the potent vasodilator calcitonin gene-related peptide (CGRP) have been found in ipsilateral jugular vein blood during the active phase of cluster headache (CH) and this is hypothesized to cause distinctive vasodilation.The receptor activity-modifying protein 1 (RAMP1) is part of the CGRP receptor complex responsible
