Funded Activity Summary

Control and effective treatment of autoimmune diseases remain major challenges to our health system. Diseases such as multiple sclerosis, systemic lupus erythematosus, diabetes and pernicious anaemia are serious conditions that are essentially incurable. Current treatment is only effective in providing temporary relief as it is not directed against the underlying disease process. This project will manipulate the immune system in such a way that early disease processes in autoimmunity will be blocked with the ultimate goal to cure the disease. Using an experimental model of pernicious anaemia in mice, where the basic pathology is immune-mediated gastritis, the disease will be treated by presenting the disease causing autoantigen via modified, or immature, antigen presenting cells to the immune system. In other experimental models which form the background to this project we have shown that this approach leads to down-regulation of the immune response by generating cells which specifically suppress the immune system. In our studies of autoimmune gastritis we will obtain modified antigen presenting cells from the skin, the blood, the spleen and thymus and use these cells to define optimal conditions for presenting the auto-antigen molecules to achieve the ultimate goal, which is antigen specific suppression of autoimmune gastritis. Our hypothesis is that immature antigen presenting cells are unable to present antigen to induce an effective immune response, but instead induce a response that results in antigen specific suppression. We intend to use this antigen specific suppression to prevent the establishment of autoimmune gastritis as well as treatment of established disease. This is a unique and potentially valuable strategy to treat autoimmune gastritis and offers the potential to apply this approach to other autoimmune conditions
