Summary
An integral component of an immune response to foreign pathogens is the production of antibodies by B cells. However, if antibodies react to self-antigens (human molecules rather than bacteria or viruses) they may also cause autoimmune diseases such as lupus. This research project is investigating the mechanisms that control antibody generation by B cells, and how these are dysregulated in autoimmune diseases, such as lupus.
Understanding The Role Of Host Arih2 In Defence Against Viral Infection And Disease Pathogenesis

Summary
A set of proteins, called E3 ligases, modulate many aspects of immunity. Arih 2 is a novel E3 ligase that limits immune cell activation to maintain the immune system in a quiescent state. The details of how Arih2 functions and its role in immunity to chronic overwhelming infection are the focus of this study. The insights gained from these studies have important implications for our understanding of how immune responses can be promoted during infection or halted in autoimmunity.

Summary
The immune system is essential for protecting us against invasion from without by viruses and bacteria and invasion from within by cancer cells. Among the white blood cells making up this system are those responsible for producing antibodies. To ensure that all possible infections and tumours can be recognised, the body needs to manufacture a very large number of these cells on a continuous basis.

Among the white blood cells making up this system are those responsible for producing antibodies. To ensure that all possible infections and tumours can be recognised, the body needs to manufacture a very large number of these cells on a continuous basis. The aim of this project is to work out the mechanism responsible for controlling their production and function using a novel experimental system. By pinpointing the different stages involved in antibody production in the normal host we should be in a better position to make longer lasting vaccines in the future and to understand what goes wrong with these white cells in disease. In particular, the results should shed light on the chronic form of leukaemia called myeloma and some of the autoimmune disorders like the rheumatic diseases which occur when the antibodies being produced attack our own tissues.Read moreRead less
Synovial Macrophages And T-cells Are Therapeutic Targets In Osteoarthritis

Summary
Osteoarthritis (OA) is the most widespread musculoskeletal disease in Australia and there are currently no therapies that halt disease progression. Specific inflammatory events play a pivotal role in initiating and driving OA progression. In this study we will define the specific inflammatory cells involved in OA, how and why they change with time, and which can be targeted to stop disease onset and development. This will provide the platform for initiating human clinical trials.
Defining The Role Of Kidney CD103+Dendritic Cells For Treatment Of Chronic Kidney Disease

Summary
Chronic kidney disease (CKD) is a major cause of death and morbidity. Current treatments for CKD are not effective and new therapeutic approaches are needed. Dendritic cells (DCs) are key immune cells and play a central role in kidney disease. We recently found that a major DC subset called CD103+ DCs harmed the kidney in an animal model of human CKD. This study is to determine how CD103+ DCs cause kidney damage, and how to target CD103+ DCs for development of new therapies for human CKD.
