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.

Summary
The defence of the body to disease is a very complex process involving multiple interactions between subsets of white cells, in particular lymphocytes. This immune system, however, does not act in isolation but is subject to constant regulation by a variety of other cells and soluble factors. Particularly important in this regard is the impact of glucocorticoids which are normally associated with stress conditions. These steroids have been proposed to act at several levels in the immune system, ....The defence of the body to disease is a very complex process involving multiple interactions between subsets of white cells, in particular lymphocytes. This immune system, however, does not act in isolation but is subject to constant regulation by a variety of other cells and soluble factors. Particularly important in this regard is the impact of glucocorticoids which are normally associated with stress conditions. These steroids have been proposed to act at several levels in the immune system, usually causing suppression but they can also modify in a positive sense. Defining the targets of glucocorticoids and their precise functional impact will thus have very important implications for not only understanding the regulation of the immune response but also in the clinic. This project will make use of mice which have had the receptor for glucocorticoids genetically deleted. Focussing on T cells (the most important cells of the immune system) these mice will be examined in detail for alterations in the development of T lymphocytes and their function in defending the body against virus and tumours and their involvement in self destruction (autoimmune) diseases including multiple sclerosis.Read moreRead less

Summary
People who undergo kidney transplantation require potent anti-rejection medications. Dosing is difficult. Two people given the same drug dose can have markedly different blood drug concentrations. If drug concentrations too low, there is an increased risk of rejection. If too high, there is an increased risk of drug side effects, infections and cancer. This study aims to find out why different people need different doses and to improve dosing methods, thereby improving patient outcomes.
