Summary
Immune responses protect us against pathogens such as viruses and bacteria. However inappropriate immune responses can result in autoimmune conditions such as systemic lupus erythmatosus, multiple sclerosis, type I diabetes, asthma as well as immunodeficiencies. The aim of our proposal is to gain a thorough understanding of how all the cells of the immune system function and interact with each other, and what goes wrong when inflammatory diseases develop.

However inappropriate immune responses can result in autoimmune conditions such as systemic lupus erythmatosus, multiple sclerosis, type I diabetes, asthma as well as immunodeficiencies. The aim of our proposal is to gain a thorough understanding of how all the cells of the immune system function and interact with each other, and what goes wrong when inflammatory diseases develop. We plan to do this using state-of-of-the-art technologies, including genetically modified mice, gene microarrays, monoclonal antibodies, and flow cytometry. We have brought together Australia's leading immunologists with complimentary expertise and research interests in specific areas of immunology including cytokines, cell migration, inflammatory diseases, autoimmunity and cell-cell interactions. One aspect of the application is to understand the genetic and molecular basis of immunological diseases. However we also wish to move on from an understanding to treatment of immunological diseases through the development of novel therapeutics. We will form collaborations with biotech and pharmaceutical companies (including our own spin off companies) to advance important new therapeutics for autoimmune and allergic diseases. These conditions represent a significant health burden to Australia.Read moreRead less
The Role Of Self Reactive T Cells In The Normal TCR Repertoire

Summary
The immune system is highly regulated and sophisticated in order to distinguish foreign invaders from our own body. Once control is lost in this system, mistakes can happen, and autoimmunity, attack of ones self may result. Surprisingly potentially dangerous ‘fighter’ T cells can be readily found in healthy individuals whom are free from autoimmunity. The aim of this project is to understand how we can survive with these potentially harmful T cells around and what may activate them.

Summary
Autoimmune diseases affect 5-6% of the population and include diseases such as multiple sclerosis. Our studies focus on examining a gene therapy approach together with bone marrow transplantation to treating autoimmune diseases. Using a model for multiple sclerosis we are finding promising results

Summary
Type III hypersensitivity underlies a number of common autoimmune diseases, including rheumatoid arthritis and lupus erythematosus. These diseases are caused by the deposition of immune complexes (IC) and the accumulation of neutrophils within small blood vessels. We will use real time imaging to dissect in space and time the recruitment of neutrophils and IC deposition during type III hypersensitivity reactions in order to better understand the pathogenesis of these conditions.
My research is directed to the prevention of diabetes, across the spectrum from type 1 to type 2 diabetes. It is based on understanding immune-inflammatory mechanisms that contribute to dysfunction and death of pancreatic insulin-secreting beta cells and tissue resistance to the action of insulin. I study these mechanisms in rodent models and in humans in the context of relevant environmental factors and genes, with the aim of manipulating them for therapeutic benefit.
Understanding The Critical Mechanisms That Govern Regulatory T Cell Life And Death Decisions

Summary
Autoimmune diseases impose an increasingly large health burden. Treg cells prevents the immune system from attacking “self” offering the promise of using these cells to restore immune balance in autoimmune diseases. However, there are currently no protocols that reliably modify Treg cell numbers. This study will elucidate the mechanisms that govern Treg cell survival and death, revealing potential molecular targets to manipulate the quality and quantity of Treg cell for therapeutic benefit.
A new approach to reversing and preventing immune-mediated diseases. Chronic inflammatory diseases affect up to 20 per cent of Australians. These diseases reduce wellbeing and life potential and shorten lifespan. This project addresses the urgent need for effective therapies and focuses on developing strategies for disease cure and prevention.

The principal goal of the CRN is to positively impact the life of people with T1D in Australia through the support and promotion of clinical research. A further electoral commitment of $35m over 5 years will enable further progress towards finding a cure for T1D, including delivering better and faster access to new therapies and treatments that can help prevent and manage the disease.

Real-time imaging of the initiation of adaptive immunity in vivo. Understanding the first few hours of an immune response is fundamental to understanding how the human immune system functions. The immune system mounts our responses to infectious diseases, but can also cause autoimmune disease, allergy, and organ graft rejection. We will study how naive antigen-specific T cells first contact antigen in lymph nodes using 2-photon intravital microscopy. The research has the potential to change the ....Real-time imaging of the initiation of adaptive immunity in vivo.

The research has the potential to change the way we think about the clonal selection of lymphocytes, the fundamental theory underlying our understanding of the immune system.Read moreRead less
