The sphincter of Oddi is a valve-like structure, which regulates the flow of bile and pancreatic juice into the gut. The sphincter of Oddi is under complex control involving nerves and hormones. We know that abnormal sphincter of Oddi function (sphincter of Oddi dysfunction) is associated with a number of human diseases including acute pancreatitis. We are able to recognise abnormal sphincter activity, but we do not know what causes it.

The sphincter of Oddi is under complex control involving nerves and hormones. We know that abnormal sphincter of Oddi function (sphincter of Oddi dysfunction) is associated with a number of human diseases including acute pancreatitis. We are able to recognise abnormal sphincter activity, but we do not know what causes it. One possible reason may be that the nerves going to the sphincter along the bile duct (which carries bile from the liver and gallbladder) may be damaged due to the passage of gallstones or during surgery on the bile ducts or gallbladder. We know that the main bile duct is able to sense pressure changes within and communicate this information (via nerves) to the sphincter which inturn alters its activity to relieve the pressure. Where these nerves are located and the chemical messages they use, are unknown. The aim of this project is to gain some of this information. This knowledge may allow us to design different surgical procedures or develop drugs to prevent or manage the abnormal sphincter of Oddi.Read moreRead less

Summary
Biliary Atresia (BA) and Cystic Fibrosis Liver Disease (CFLD) are important causes of childhood cirrhosis. Diagnosis is difficult, treatments problematic, and outcomes suboptimal. In BA, bile duct obstruction in infants rapidly progresses to liver failure. It is the most common indication for liver transplantation in children. CFLD causes significant morbidity/mortality in about 20% of CF children. This proposal investigates the mechanisms of liver fibrosis (scarring) and the role of fibrosis in ....Biliary Atresia (BA) and Cystic Fibrosis Liver Disease (CFLD) are important causes of childhood cirrhosis. Diagnosis is difficult, treatments problematic, and outcomes suboptimal. In BA, bile duct obstruction in infants rapidly progresses to liver failure. It is the most common indication for liver transplantation in children. CFLD causes significant morbidity/mortality in about 20% of CF children. This proposal investigates the mechanisms of liver fibrosis (scarring) and the role of fibrosis in both diagnosis and predicting clinical outcome.Read moreRead less
