This project introduces a new biomarker in systemic lupus erythematosus termed an apotope. The aims are to study the diagnostic potential of an apotope of Ro60, a key target in lupus, together with its ability to initiate the disease and cause organ damage. The interaction of the Ro60 apotope with a novel protective factor called beta2-glycoprotein I will also be studied. These discoveries are likely to lead to new diagnostic tests and preventions for lupus and neonatal lupus.
Investigation Of The Role Of Specific Mucous Associated Bacteria In Children And Young Adults With Crohns Disease

Summary
The role of bacteria in Crohn's disease is well accepted however to date no conclusive agents have been identified. Recent animal studies have implicated mucus-associated bacteria. We have recently shown that such bacteria, the Helicobacteriaceae, are present in humans and children with Crohn's disease. The aim of this project is to determine in children and young adults the role of these bacteria in IBD thus providing information that could be used to design improved therapies for IBD.
Pathogenesis Of A New Mouse Model Of Ankylosing Spondylitis

Funding Amount
$682,820.00
Summary
Ankylosing spondylitis and Crohn's disease are autoimmune inflammatory diseases which cause long-term pain and deformity of joints, spine and bowel. Using a new mouse model of both diseases, we will study cells and processes involved in the initiation of disease, in order to discover new targets for prevention and treatment. The work will have importance for design of new therapies for human inflammatory spine and bowel diseases.
Intra- And Intercellular Spreading In Shigella Pathogenesis

Funding Amount

Summary
Each year Shigella flexneri bacteria cause over 167 million episodes of dysentery and over 1 million deaths worldwide, under conditions of poor sanitation, in both developed and developing countries. No vaccines are available, and resistance to antibiotics is common. This project will study the a key part of the machinery that allows bacteria use to cause disease, and also to identify drugs that block the machinery which can in future be used to treat infection by these bacteria.
Understanding Determinant Selection In Autoimmune Diseases

Funding Amount
$686,656.00
Summary
Understanding what the immune system perceives during infection or in autoimmunity is key to the development of improved vaccines and therapies for a variety of human diseases. This proposal builds on leading research into the definition of targets of immunity in autoimmune diseases using cutting edge proteomic technologies. The proposal focuses on type 1 diabetes, multiple sclerosis, lupus and rheumatoid arthritis and will delineate candidate therapeutic molecules.
The Role Of MHC Class I Expression On Pancreatic Ductal Lineage Cells In The Pathogenesis Of Type I Diabetes (TID).

Summary
MHC molecules act as traffic lights to the immune system telling it whether to stop or go, so that only when there is an infection does the immune system receive the signal to destroy target cells. However, the immune system in Type 1 Diabetes patients receives signals to destroy the insulin-producing cells when there is no apparent infection. We aim to determine where the faulty traffic signal occurs and so be in a better position to design intervention strategies to prevent Type 1 Diabetes.
