Newly developed serine protease inhibitors decrease visceral hypersensitivity in a post‐inflammatory rat model for irritable bowel syndrome

Abstract

Increased expression of serine proteases and activity together with increased expression of downstream molecules at the colonic and DRG level and in CGRP-positive sensory nerve fibres imply a role for serine proteases in post-inflammatory visceral hypersensitivity. Our results support further investigation of serine protease inhibitors as an interesting treatment strategy for IBS-related visceral pain.
