Calcitonin Gene-Related Peptide

Member of the calcitonin family

α and β forms

37 amino acids

derived from cell bodies of spinal cord motor neurons — helps with regeneration

derived from dorsal root ganglia — linked to transmission of pain

derived from trigeminal ganglion — involved in migraine

involved in cardiovascular homeostasis

CGRP in Migraine

Meningeal nociceptors from the trigeminal ganglion release CGRP

CGRP binds to CGRP receptors on meningeal vessels

potent neurogenic vasodilator

Triptans block CGRP

acutely

Botox prevents release of CGRP by cleavage of SNAP-25 protein

monoclonal antibodies block CGRP after monthly infusion

anti-CGRP antibodies

Aimovig® : erenumab-aooe

Ajovy® : fremanezumab-vfrm

Emgality® : galcanezumab-gnlm
