Summary
Bone marrow transplantation remains a mainstay of curative therapy for haematological malignancies. This curative effect is mediated by the transplanted donor immune system which rejects the recipient malignancy. However, the procedure is limited by its serious side effect, known as graft-versus-host disease. This application seeks to better understand these two processes at both an immunological and clinical level with the aim of separating the two so that more patients may be cured of leukaemi ....Bone marrow transplantation remains a mainstay of curative therapy for haematological malignancies.

Summary
This project is aiming to develop an “off-the-shelf” killer T cell therapy for transplant patients and patients with virus-associated malignancies. This therapy is based on a novel technology developed by our group which allows rapid expansion of killer T cells directed against multiple viruses.

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.

An investigation into the basis of the T-cell mediated adaptive immune response. Understanding the adaptive immune response to human pathogens is critically important to develop strategies to combat infection. This project will provide a better understanding of how T cells combat viral infection, and will lead to fundamental advances in our understanding of viral immunity and the development of novel immunotherapeutic strategies.

Summary
The purpose of this work is to identify how a select population of cells (T regulatory cells) function to prevent or dampen down the sometimes-harmful effects of the immune system. Understanding how these cells function may have broad implications for general immune regulation.

Multiphoton microscopy of living animals as a tool for immunology and cell biology studies. The multiphoton microscope will enable us to watch the growth, migration and interactions of cells in a living animal in response to changes in the cells' environment will give us better understanding of how we work as living machines, and what can go wrong with that process to make us unwell.
CD39 Protects Against Renal Ischaemic-reperfusion Injury

Summary
In many medical settings, such as heart attacks, strokes, transplantation, heart surgery, shock and infection, the blood supply to an organ may be compromised resulting in damage. The cessation of blood flow depletes the organ of oxygen and generates a number of toxic changes. Re-establishing blood flow to the organ is essential to prevent further damage, however the reestablishment of blood flow itself can be harmful to the organ. The return of blood flow, oxygen and energy can actually promote ....In many medical settings, such as heart attacks, strokes, transplantation, heart surgery, shock and infection, the blood supply to an organ may be compromised resulting in damage. The cessation of blood flow depletes the organ of oxygen and generates a number of toxic changes. Re-establishing blood flow to the organ is essential to prevent further damage, however the reestablishment of blood flow itself can be harmful to the organ. The return of blood flow, oxygen and energy can actually promote more widespread injury - a process known as ischaemia-reperfusion injury (IRI). A greater understanding of IRI should aid in the development of drugs that minimise its impact. The overall aim of this work is to examine the role of a molecule - CD39 - in IRI. This molecule is ideally situated to minimise injury - it is located on cells that line blood vessels and, as such, is able to directly neutralise toxins released in response to this injury. We, therefore, believe that it will be protective in this setting. We have developed animals that express this molecule and have preliminary results to suggest that these animals are protected in experimental models of IRI as well as in several other models including heart transplantation surgery; processes that share many features with IRI. Moreover, mice deplete of this molecule are prone to more severe IRI. We aim to investigate this by using animals both lacking and expressing CD39. Blood flow to the kidneys will be interrupted for 30 minutes and kidney function assessed at 24 and 48 hours. We will then delve into the potential mechanisms underpinning IRI by determining whether the kidney itself or the blood cells afford protection, which has direct clinical implications.Read moreRead less
