Summary
Pain and discomfort from the gut are common and unpleasant. We understand how gut sensory nerve cells work, at the cellular, molecular and genetic level. However, movement of the gut wall and contents are the major cause of activation of sensory neurons. We know little about which particular patterns of movement cause pain. This is crucial information for accurately diagnosing human gut disorders, for monitoring effectiveness of treatments and for identifying potential new drug targets.
The Physiological And Pathological Role Of The Bile Acid Receptor TGR5 And Its Potential Targeting For The Treatment Of Intestinal Motility Disorders And Visceral Pain.

Summary
Defects in the secretion of bile into the intestine cause digestive diseases, and abnormal circulating levels of bile acids induce profound itch and abnormal pain sensation. This project examines whether a cell-surface receptor (TGR5) produced by intestinal and sensory neurons mediates actions of bile acids on intestinal functions and pain. The project aims to define mechanisms of digestive and sensory disorders and identify new therapies for constipation, diarrhoea, and pain.
BRAIN IMAGING OF CARDIOVASCULAR CONTROL DURING MUSCLE PAIN

Summary
One in every five people in Australia suffers chronic pain and a third of these have severe pain associated with severe disability. The incapacitating effects of long-lasting pain are not just psychological, but affect many systems, including the cardiovascular system. We are interested in why pain causes blood pressure to increase in some people but not in others: patients with post-surgical chronic pain have nearly twice the prevalence of clinical hypertension than patients without pain.
