Summary
Multiple Sclerosis (MS) is the most common cause of paralysis in young people. EAE is an animal model of MS that recapitulates many features of the human disease. Recent data shows that EAE is mediated by IL-17 producing self-reactive T cells. NKT cells are a group of T cells, whose activation protects against EAE, in an as yet unidentified manner. These studies will provide critical information on the way in which NKT cells regulate immunity and will enhance development of therapies for MS.

Summary
This project will analyse mechanisms that regulate CD4 T cells and normally prevent the immune system from attacking parts of our own body. Unknown errors in the control of T cells result in autoimmune diseases such as Type 1 diabetes, multiple sclerosis, and thyroid disease, where T cells damage or destroy vital organs. In order to develop rational, specific methods for treating and preventing these diseases, it is necessary to identify and understand the genetic and biochemical mechanisms that ....This project will analyse mechanisms that regulate CD4 T cells and normally prevent the immune system from attacking parts of our own body. Unknown errors in the control of T cells result in autoimmune diseases such as Type 1 diabetes, multiple sclerosis, and thyroid disease, where T cells damage or destroy vital organs. In order to develop rational, specific methods for treating and preventing these diseases, it is necessary to identify and understand the genetic and biochemical mechanisms that normally control T cell cell responses to self components, and how inherited defects lead these mechanisms to break down. The project focuses on defining how CD4 T cell regulation breaks down in two well established examples of inherited susceptibility to autoimmune disease. The direct action of autoimmune susceptibility genes will be determined at the level of the specific T cells responsible for autoimmune attack and in terms of the biochemical pathways within T cells that are dysregulated. By identifying the mechanisms and biochemical pathways that are dysregulated in autoimmune disorders, the results of this project will reveal targets for understanding and diagnosing autoimmune diseases and for developing new drugs or or vaccines to prevent T cells damaging vital organs and cure these diseases.Read moreRead less
Investigating T Cell Tolerance And Organ-specific Auotimmunity Using Autoantigen Deficient Mice

Summary
The immune system normally protects against invasion by pathogens such as harmful viruses and bacteria. In autoimmune diseases the same mechanisms that are used to protect us are erroneously targeted to our own tissues. Our studies will employ technologies to genetically manipulate mice to further our knowledge of this class of disease and to uncover the normal mechanisms that allow the immune system to prevent autoimmune attack. In particular we will gain information on the way that a new class ....The immune system normally protects against invasion by pathogens such as harmful viruses and bacteria. In autoimmune diseases the same mechanisms that are used to protect us are erroneously targeted to our own tissues. Our studies will employ technologies to genetically manipulate mice to further our knowledge of this class of disease and to uncover the normal mechanisms that allow the immune system to prevent autoimmune attack. In particular we will gain information on the way that a new class of lymphocytes, known as regulatory lymphocytes, are able to protect against autoimmune disease. Such regulatory lymphocytes have been identified in humans and are attractive therapeutic agents to prevent a variety of immune-mediated diseases, including autoimmune diseases, allergy and transplantation rejection.Read moreRead less
