Treatment of inflammatory bowel disease with neural stem cells expressing choline acetyltransferase.

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder, with increasing incidence and prevalence in the last one-half century. IBD patients suffer from autonomic vagal neuropathy and nerve dysfunction, with deficiency of acetylcholine in inflamed mucosa. Recent studies showed that death of enteric neuron in local tissue was induced during the process of IBD, which also played a crucial role in the pathogenesis of disease. Stem cells have been demonstrated a new biological treatment for IBD, therefore, we proposal that neural stem cells expressing choline acetyltransferase may enhance enteric neural cell regeneration, restore acetylcholine production in intestinal mucosa, and thus inhibit immune responses of IBD.
