Summary
In this study, we will determine the roles of the antigen presenting cells, namely denderitic cells, in the induction of T-regulatory cell (T-reg) developemnt in the thymus. T-reg cells play important roles in controlling the development of autoimmunity. This study will help to understand the possible causes of autoimmune diseases and to develop new treatments for these diseases.

Summary
T cells are the sentinels of our immune system continually scanning our tissue for abnormalities and eliminating threats in many forms. They are our second and last line of defence against microorganisms and cancer. Unfortunately, T cells can also cause harm through accidental crossreactvity or overzealous function. My work is directed at understanding how T cells work and how they can be controlled using drugs and gene therapy. If we can ‘tune’ the power of this master immune lineage we can unl

Summary
Immuno-modulators utilize the patient’s own immune system to eliminate or slow the growth of cancerous cells. We have identified a novel immuno-modulator which could be a significant player in immune-modulation therapy for the treatment of cancer. We will use the development grant to develop a product which has significant potential to be the next generation treatment for cancer.
I am an immunologist, working to understand the function of NKT cells, and how these cells can be manipulated as a means of immune therapy for a range of immunologically related diseases.

Summary
Type III hypersensitivity underlies a number of common autoimmune diseases, including rheumatoid arthritis and lupus erythematosus. These diseases are caused by the deposition of immune complexes (IC) and the accumulation of neutrophils within small blood vessels. We will use real time imaging to dissect in space and time the recruitment of neutrophils and IC deposition during type III hypersensitivity reactions in order to better understand the pathogenesis of these conditions.

Summary
Autoimmune diseases constitute a significant medical problem in the developed world and are increasing in incidence. Many control mechanisms exist in the body, but in people with genetic suceptibility to autoimmune disease, the mechanisms fail and the body's immune sytem attacks normal tissues or organs. We have developed a new approach to using the cells which train the immune system to re-educate the cells that would otherwise attack normal healthy tissues in autoimmune-prone individuals.

Many control mechanisms exist in the body, but in people with genetic suceptibility to autoimmune disease, the mechanisms fail and the body's immune sytem attacks normal tissues or organs. We have developed a new approach to using the cells which train the immune system to re-educate the cells that would otherwise attack normal healthy tissues in autoimmune-prone individuals. These cells (dendritic cells) are genetically modified to express the molecular targets of the autoimmune response. This in turn switches off the response to these targets. In this project we will explore how these cells can be used to turn off cells of the immune system and if cells of the immune system in turn control the dendritic cell's ability to do this.Read moreRead less

Summary
The immune response is the body's defense system. It's malfunction leads to many diseases such as immune deficiency, asthma and cancer. Thus, it is important to find genes controlling immunity. Significantly, mammals have amazing similarities with flies, in terms of genes controlling immunity. We have found a new regulator of fly immunity and will define how this gene functions in the immune system. This project will identify potential points of intervention for treating immune system disorders.
Connections between nerve cells in the brain often occur onto enlarged protrusions called dendritic spines. This proposal will investigate the properties of dendritic spines, and relate differences in spine properties to synaptic plasticity. This information can be used to better understand and treat neurological disorders associated with spine malfunction, as occur in some forms of mental retardation, and may help with understanding the memory loss that occurs during ageing and dementia.
