Genetic and biochemical mechanisms dysregulating CD4 T cell tolerance in organ-specific autoimmunity

Funded Activity 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 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.
