Migraine and temporomandibular disorders (TMD) are prevalent, debilitating orofacial pain conditions involving peripheral and central sensitization of the trigeminal system. The pro-inflammatory neuropeptide calcitonin gene-related peptide (CGRP), which is synthesized and secreted from trigeminal ganglion neurons, is implicated in the underlying pathology of migraine and TMD. Secreted CGRP modulates the excitability state of neurons and glial cells that express CGRP receptors. Recent studies from our lab in preclinical models of migraine and TMD have provided evidence that dietary supplementation with a proanthocyanin-enriched grape seed extract (GSE) inhibits trigeminal pain signaling. The effect of GSE was blocked by an antagonist of …
