Deep dives
Understanding PACAP in Migraine Pathophysiology
PACAP, or Pituitary adenylate cyclase-activating polypeptide, plays a crucial role in migraine pathophysiology, particularly within the trigeminal vascular system, where it is activated during migraine attacks. This neuropeptide is involved in several biological processes such as vasodilation and pain transmission. Clinical experiments have demonstrated that PACAP can induce migraine attacks in individuals with a migraine history, indicating its significant impact on migraine mechanisms. The activation of PACAP receptors distinguishes it from CGRP, showcasing its unique role in migraine-related vasodilation and inflammation.
