My research group works on the immunopathogenesis of type 1 diabetes. We use pancreatic beta cells and T cells purified from genetically-modified mice to investigate the role of perforin, death receptors and inflammatory cytokines in beta cell death and diabetes. Our team also identified the primary role of autoimmune recognition of proinsulin in type 1 diabetes and we are developing antigen-specific therapies to prevent diabetes. I also lead a Melbourne-wide clinical islet transplant program that began treating diabetic patients by infusion of isolated islet cells in 2006. It is hoped that a detailed knowledge of how beta cells are destroyed in our research studies will indicate the most effective forms of immunoprotection and could eventually allow beta cell replacement as a treatment for type 1 diabetic patients without systemic immunosuppression.
