Mast cells trigger epithelial barrier dysfunction, bacterial translocation and postoperative ileus in a mouse model

Abstract

Mast cell activation during abdominal surgery causes epithelial barrier dysfunction and inflammation of the muscularis externa of the bowel. The impairment of the epithelial barrier likely contributes to the pathogenesis of POI. Our data further underscore that mast cells are bona fide cellular targets to ameliorate POI.
