We evaluated endosomal signaling of protease-activated receptor-2 (PAR<sub>2</sub>), which has been proposed to mediate pain in patients with irritable bowel syndrome (IBS).
Electroacupuncture Relieves Visceral Hypersensitivity by Inactivating Protease-Activated Receptor 2 in a Rat Model of Postinfectious Irritable Bowel Syndrome.
This study examined whether mediators from biopsies of human irritable bowel syndrome (IBS) colons alter intrinsic excitability of colonic nociceptive dorsal root ganglion (DRG) neurons by a protease activated receptor 2 (PAR2)-mediated mechanism.
