    Summary

    There is increasing evidence to suggest that intestinal inflammation affects the organization and function of the intestinal nervous system, which controls how our intestine works.  As a result, changes in nerve function may alter how the inestine works, worsen inflammation and aggravate the symptoms in IBD.  In our studies we are examining the nerve-intestinal lining responses to inflammation in animal models if IBD and in our children with IBD.  We will determine what nerve changes occur in assoications with intestinal inflammation, how these changes affectr the function of the intestinal lining cells and whether these changes persist.  We will also examine the potential benfit of probiotics (living non-harmful bacteria).

    We are also examining the effects of maternal dietary fat on intestinal lining cells (which protect the host from harmful dietary agents and infectious organisms) and on the intestinal immune response in young offspring.

    Current Projects
    • Determining the effect of intestinal inflammation on neuro-epithelial function in animal models of IBD.
    • Examining the role of maternal dietary lipid in modulating epithelial barrier function and intestinal immune response of the young offspring to chemically induced colitis
    • Epidemiology of paediatric IBD
