Summary
The aim of my research is to improve transplant outcomes by developing novel, clinically realistic, therapeutic options for patients with end-organ failure and for a specific cohort of patients with type 1 diabetes. The goal is to advance transplantation by developing a strong interactive research environment where initiatives are quickly interchanged between the laboratory and the clinic. These include novel trials in islet transplantation and use of genomics to improve transplant outcomes.
Improving Outcomes Of Transplantation By Targeting Retrieval, Care And Complications

Summary
Our aim is to find out what the problems related to organ transplantation are in order to suggest ways of intervening to help reduce these problems for patients and the health care system. We will work closely with the team at one of Australia's leading transplant centres at Westmead Hospital to try and find safe and economic ways to tackle issues of organ shortage, those that come up during the organ donation and in the wider care of patients improve the practice.

Summary
Solid organ transplantation is the most effective therapy for treating organ failure and some cancer. However, a common complication that occurs is graft rejection. The current aim is to develop procedures that reduce the risk of graft rejection without the use of immunosuppressive drugs, which can be toxic and make recipients more susceptible to infection. We are investigating the ability of a cell that is part of the immune system to down-regulate over-reactive immune responses and therefore r ....Solid organ transplantation is the most effective therapy for treating organ failure and some cancer.

Bridging The Gap In Kidney Transplantation Using Pigs As Donors

Summary
Chronic kidney failure results in patients suffering significant morbidity and mortality ultimately requiring life-supporting dialysis. Kidney transplantation and lifelong immunosuppression are the only treatment, but (i) is limited by the shortage of human donors and (ii) carries risks associated with these anti-rejection drugs. This project aims to solve both problems by using humanized pigs as donors combined with a novel approach to inducing acceptance of the transplanted kidneys.
Immunobiology Of Carbohydrate Antigens In Xenotransplantation

Summary
Xenotransplantation, the transplanting of organs from other species, is now seen as a viable solution to the problem of lack of supply of suitable human donors. The recent production of genetically engineered pigs represented a critical step towards clinical xenotransplantation. However, other sugars still remain that cause rejection. This project examines the consequences of these sugars.

Summary
Advances in surgical and immunosuppressive techniques has led to organ transplantation as the method of choice for the treatment of many diseases. However, the number of suitable donors is dwindling, due to many factors, but largely as a result of the reduction in deaths from car accidents. Xenotransplantation, the transplanting of organs from species other than humans, is now seen as a viable solution to the world wide problem of lack of supply of suitable human donors.

However, the number of suitable donors is dwindling, due to many factors, but largely as a result of the reduction in deaths from car accidents. Xenotransplantation, the transplanting of organs from species other than humans, is now seen as a viable solution to the world wide problem of lack of supply of suitable human donors. The pig is the most suitable for a variety of reasons. However, the problem is that all humans contain natural antibodies to the pig which would lead to rejection within a few minutes as the antibodies bind to the transplant and reverse its rapid destruction (so called hyperacute rejection). Recent studies from our laboratory have indicated that most, if not all, of the antibodies react with the sugar - galactose present on many molecules on the surface of transplanted pig tissues. Our studies have indicated very large amounts of this material present in pig blood vessels - guaranteeing the early rejection of transplanted organs such as kidney, heart and liver. The production of knockout pigs which do not express the galactose sugar is an important pre-requisite for successful xenotransplantation. Recently knockout pigs which lack an enzyme that makes this sugar have been produced, but not all the sugar was destroyed. We have recently described a second novel enzyme that also makes this sugar. We will examine a role of this enzyme in xenotransplantation. These studies will be the prelude to the production of pigs which could be used for human transplantation.Read moreRead less
Detection Of Cardiac Allograft Rejection By Peripheral Blood Gene Expression: A Novel Concept Of Personalized Approach To Transplantation.

Summary
Heart biopsy is required to detect rejection after heart transplantation. The cost of each biopsy is around $7,000 and at least 10 heart biopsies needed in the first post-transplant year alone. The biopsy is difficult for the patients and significant cost for the Australian healthcare system. Thus, it would be beneficial to identify rejection using a simple blood test. Such tool would help to reduce or eliminate the need for expensive heart biopsy and would reduce the cost by about 10 times.

The Role Of Th17 And Tregs In The Development Of Tolerance And Rejection In A Murine Model Of Renal Allograft Rejection

Summary
In clinical transplantation, rejection remains the greatest problem in determining both short and long-term patient outcomes. Tolerance, the ability of the body to accept a transplant without immunosuppressive drugs, remains an as yet unattained goal. The aim of this project is to examine the mechanisms by which the initial immune response (innate immunity) affects the development of tolerance or rejection in a mouse model of kidney transplantation.
