Unraveling Mechanisms Of Liver Transplant Tolerance

Summary
Liver transplants are unique amongst solid organs as they are spontaneously accepted across different individuals and induce acceptance of other organs from the same donor co-transplanted at the same time. Using a new mouse liver transplantation model, this proposal will elucidate how the liver tissue performs this function and identify new markers associated with tolerance in the blood of mice. This knowledge will be used to identify liver transplant patients with reduced rejection risk.

Tragically patients whom suffer from diabetes mellitus develop major secondary complications such as renal failure, even with today's tight glucose control. Insulin injections minimise diabetic complications but restricts lifestyle and an alternative, pancreatic islet cell transplantation, is limited by donor shortage.

Insulin injections minimise diabetic complications but restricts lifestyle and an alternative, pancreatic islet cell transplantation, is limited by donor shortage. With genetic technology, pig donor tissue is a feasible donor source. This project will use an inbred pig colony to assess long term pig fetal and neonatal islet cell function in combination with a kidney graft in the absence of an immune response. Using this specifically inbred pig colony we will carefully catalogue the type, number and distribution of endogenous retroviruses within pig genes. Using new and novel techniques we will develop a new strategy by which we can block and overcome this major concern of xenotransplantation. Ultimately a unique Australian resource will be developed which may provide unlimited islets for safe, large-scale transplantation of diabetics before they develop debilitating secondary complications from their diabetes and provide an alternative to the only current method of curing endstage renal failure with a combined pancreas and kidney transplant.Read moreRead less
