Summary
Autoimmune diseases affect 1 in 20 Australians and are incurable. To find effective therapies, we need to understand the genes that cause disease in humans. We have sequenced the entire genome of patients with an autoimmune disease and found several patients carrry two mutations in genes important for activation of B cells and shown these mutations cause disease. We plan to understand how these genes prevent autoimmunity, and to identify the best treatment for patients with these mutations.
Molecular Signatures Of Public Clonotypes In Human Systemic Autoimmunity

Summary
New platform technology has been developed to study autoantibody clones in lupus and Sjogren's syndrome. This approach has furthered our understanding of these disorders by the discovery of unique sets of clones that are common to all patients. The unique "molecular signatures" of these clones can be translated to a next-generation diagnostic that detects them in patients at extremely low levels missed by conventional tests.
Rogue B Cell Clones In Patients With Autoimmune Disease

Summary
Our immune system protects us from disease by producing antibodies. However, 5% of Australians suffer from an autoimmune disease where they produce “auto” antibodies, which attack their own organs. This research will study the cells (termed B cells) responsible for making autoantibodies to determine how they differ from B cells that defend against disease. The goal is to develop therapies that eliminate autoantibody producing B cells from patients while preserving the immune system.
Exploring The Contribution Of Interferon-lambda To Autoimmune Disease

Summary
We have found that a novel protein, normally made in response to viral infections, is found in the blood of Lupus patients. This project will determine the cells that make this protein, what in Lupus blood makes these cells produce it and whether it plays a role in the severity of Lupus disease.
How Does Disruption Of Serinc1 Expression Affect Lymphocyte Function And The Development Of Autoimmunity?

Summary
Autoimmune diseases affect up to 8% of the population. We have recently discovered a novel gene mutation in mice that results in increased levels of anti-nuclear antibodies, a hallmark of various autoimmune diseases in humans. The mutated gene, Serinc1, has not been previously implicated in autoimmune disease, but it is important for synthesis of key molecules in immune cells. This research proposal aims to determine how disruption of Serinc1 contributes to the development of autoimmune disease.
