CGRP induces vasodilation. It dilates a variety of vessels including the coronary, cerebral and systemic vasculature. Its abundance in the CNS also points toward a neurotransmitter or neuromodulator role. It also elevates platelet cAMP (By similarity). Detected in nerve cells of cerebrum, hippocampus and pons/midbrain in newborns, and only in nerve cells of pons/midbrain in adult. Belongs to the calcitonin family.
