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.
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 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 way we think about the clonal selection of lymphocytes, the fundamental theory underlying our understanding of the immune system.Read moreRead less

Summary
Multi-photon imaging for infection, immunity, and self recognition. This proposal will address a gap in our imaging capabilities, allowing us to visualise the movement of immune cells and infectious agents such as bacteria and viruses within living tissues. This will immensely improve our capacity to understand interactions between the immune system, invading organisms and the rest of our body. The intravital imaging system will provide novel insights into how the immune system works, which will ....Multi-photon imaging for infection, immunity, and self recognition. This proposal will address a gap in our imaging capabilities, allowing us to visualise the movement of immune cells and infectious agents such as bacteria and viruses within living tissues. This will immensely improve our capacity to understand interactions between the immune system, invading organisms and the rest of our body. The intravital imaging system will provide novel insights into how the immune system works, which will benefit the design of vaccines, the treatment of cancer, and our understanding of allergy. This state-of-the-art facility will also provide vital training in an emerging technology that will have application in many areas of biology.

This project aims to undertake discovery research to investigate the molecular mechanisms underpinning the role of lipids in T cell immunity: an emerging area of immense biological significance. The anticipated goal is to generate new knowledge in the areas of the life sciences, by using a multidisciplinary approach that includes structural biology, mass spectrometry, biophysics, and cellular immunology, to gain fundamental insight into molecular determinants that govern lipid mediated immunity. Expected outcomes and benefits of this project include building international and interdisciplinary collaborations to enhance national research capacity, and provide marked advancement of core knowledge in the biological sciences.Read moreRead less

Summary
An advanced flow cytometry facility for the Peter Doherty Institute. The establishment of a flow cytometry facility in the new Peter Doherty Institute for Infection and Immunity will enhance capacity to investigate immunity to a broad range of very serious diseases. This project will support researchers studying viral and bacterial infection as well as cancer and autoimmunity.

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
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
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.
