Dietary constituent genistein inhibits the hyperexcitability of trigeminal nociceptive neurons associated with mechanical hyperalgesia following orofacial inflammation.
Abstract
Genistein, a dietary constituent, modulates voltage-dependent and ligand-gated ionic channels, suggesting that it could also attenuate inflammatory hyperalgesia. However, the mechanism underlying how genistein affects inflammation-induced hyperexcitability of nociceptive neurons in vivo remains to be determined. The present study therefore investigated whether administration of genistein could attenuate the inflammation-induced hyperexcitability of trigeminal spinal nucleus caudalis (SpVc) neurons associated with mechanical hyperalgesia in vivo.
