We use a mouse model of inflammatory bowel disease (IBD) to determine how sensations from the inflamed gut are processed in the spinal cord. Over 60,000 Australians suffer from IBD and debilitating pain is a major symptom. Surprisingly, we know very little about how pain signals originating in the normal or the diseased gut are organised and processed in the central nervous system. Obtaining such information is a necessary first step before we can develop therapies to relieve gut pain.

Summary
There has been substantial interest in the community for pain relief without opiates. This project demonstrates a new strategy to suppress pain at the source for prolonged periods, by suppressing activity in the sensory nerve endings that detect pain, not by acting in central pathways like opiates. To do this, we use a harmless virus to shut down a vital sodium channel for pain perception. These experiments use techniques that were recently developed in our lab and cant be performed elsewhere.
