NKT cells are a type of lymphocyte with the ability to prevent a broad range of diseases including cancer, autoimmunity, infection and graft rejection. Sometimes, NKT cells also cause diseases, including allergy and atherosclerosis. Therefore, the ability to modulate these cells an important health objective. This project will investigate how NKT cells become activated by studying their surface receptors and what these receptors interact with.

Summary
In addition to the lymphocytes, which are specialised white cells that can learn to defeat the infections that the body has been previously exposed, the body has a number of other defences. These non-learning systems have been honed by evolution and usually form an effective first-line of defence. This proposal deals with three: complement, and two highly specialised types of white blood cell, the Natural Killer cells and the NKT cells. The project will study mice especially bred to carry differ ....In addition to the lymphocytes, which are specialised white cells that can learn to defeat the infections that the body has been previously exposed, the body has a number of other defences. These non-learning systems have been honed by evolution and usually form an effective first-line of defence. This proposal deals with three: complement, and two highly specialised types of white blood cell, the Natural Killer cells and the NKT cells. The project will study mice especially bred to carry different versions of the genes which control these defences. Particular attention will be paid to their involvement in the autoimmune diseases, type 1 diabetes and lupus.Read moreRead less
Allogeneic stem cell transplantation (SCT) remains the most effect curative treatment for patients with a number of malignant conditions, especially leukemia. The ability to cure leukemia by this procedure relates to a process known as Graft-versus-Leukaemia effects (GVL) which ocurrs when the newly transplanted stem cells (which includes the immune system) recognises the leukemia as foreign and mounts an immune attack against it. These studies will focus on the effect of a cellular pathway invi ....Allogeneic stem cell transplantation (SCT) remains the most effect curative treatment for patients with a number of malignant conditions, especially leukemia. The ability to cure leukemia by this procedure relates to a process known as Graft-versus-Leukaemia effects (GVL) which ocurrs when the newly transplanted stem cells (which includes the immune system) recognises the leukemia as foreign and mounts an immune attack against it. These studies will focus on the effect of a cellular pathway invilving NKT cells that preliminary data suggests is critical to the development of GVL. Methods to augment this activation pathway will be studied in preclinical models that may then be studied in clinical trials with the aim of improving the outcome of patients transplanted for leukemias.Read moreRead less
