The effects of intestinal inflammation on the currents and channels of identified enteric neurons

Funded Activity Summary

Intestinal inflammation, in gastroenteritis, Crohn's disease, ileitis or colitis, has effects on the motility (movement) of the gastrointestinal and on secretion within it. The symptoms that are recognised are poor digestion, crampy pains and diarrhoea. The symptoms often continue after the inflammation has subsided. The major disease entity that can develop after inflammation is the irritable bowel syndrome (IBS). IBS is associated with persistent disorders of bowel motility. The symptoms are triggered by changes in the properties of enteric neurons, many of which become hyperexcitable. Enteric neurons are part of the nervous system within the gut wall. However, the neurons that have changed properties after inflammation have not been identified, and the mechanisms of change are not known. This work is designed to determine the molecular basis of the changes in neuron excitability that lead to hyperexcitability. Identification of the molecules whose properties are changed will permit those molecules to be targeted in the design of compounds to treat the abnormalities of intestinal physiology that follow inflammation.
