Vagal Transient Receptor Potential Ankyrin 1 Mediates Stress-exacerbated Visceral Mechanonociception After Antral Cold Exposure.
Abstract
Abdominal pain can be evoked or exacerbated after gastrointestinal cold stimulation in some patients with diarrhea-predominant irritable bowel syndrome (IBS-D), indicating a low temperature-induced sensitization of visceral perception. We investigated the role of vagal transient receptor potential ankyrin 1 (TRPA1, a cold-sensing ion channel) in cold-aggravated visceral mechanonociception in a stress-induced IBS animal model.
