Calcitonin gene-related peptide
Calcitonin gene-related peptide or CGRP is a neurosensory peptide that has a key role in pain and is a key sensory neurotransmitter involved in immune function, and is mainly expressed in the central and peripheral sensory nerves. CGRP is part of the calcitonin gene family. CGRP triggers migraines in people who experience migraines but not in others.
Known isoforms of CGRP are αCGRP (alpha CGRP) and βCGRP (beta CGRP).
Purpose[edit | edit source]
The nervous system and immune system release CGRP when transient receptor potential vanilloid 1 (TRPV1) is activated. CGRP regulates inflammation in the skin, has a key role in neurogenic inflammation and has protective effects on the heart.

antagonist A chemical that reduces or helps block the activity of another chemical in the body. For example, most antihistamines are H1 antagonists because they block the H1 histamine receptor, which helps relieve allergy symptoms. The opposite of an agonist.
