title: Mast cells in gastrointestinal disorders.
abstract: Mast cells are constitutively found in the gastrointestinal (GI) tract. The three major physiological functions of GI mast cells comprise of - as far as we know - regulation of GI functions, namely epithelial and endothelial functions, crosstalk with the enteric nervous system, and contribution to the host defense against bacterial, viral and parasitic agents. A number of chronic GI diseases, including inflammatory bowel disease (Crohn's disease, ulcerative colitis), celiac disease, irritable bowel syndrome, and food allergies, are thought to be associated with mast cell hyperplasia and humoral activity. Clinical conditions characterized by a decrease in mast cell functionality are not known so far. In the present review, we summarize current evidence which show that human mast cells play a central role at the GI barrier, both in health and disease.
