This established team of investigators will research into the molecular control of white blood cell formation and function, using a multidisciplinary, team approach to fundamental biological questions with a focus on potential clinical and commercial outcomes. The team will also attempt to identify new validated targets for therapeutic intervention by using both forward and reverse genetic approaches in mice coupled with complete phenotypic analyses of the blood cell system.
Type 1 diabetes (T1D) is a major chronic disease affecting over 100,000 Australians. Its treatment and complications impose a significant burden on affected individuals and their families and on the health system. T1D occurs when the immune system attacks insulin-producing cells in the islet cells of the pancreas. The team has developed ways to identify at-risk people, defined immune and genetic causes of T1D and is undertaking prevention trials and Australia's first islet transplant program.

Summary
The early events in immunity require various molecular interactions. We will examine the structural and biophysical basis for some of these interactions, including those associated with transplant rejection and autoimmunity. We will explore the impact of variation in immune response genes on immune evasion and disease susceptibility. Our basic research will determine the mechanisms by which the immune system discriminates between different self and micro-organism associated determinants.

We will examine the structural and biophysical basis for some of these interactions, including those associated with transplant rejection and autoimmunity. We will explore the impact of variation in immune response genes on immune evasion and disease susceptibility. Our basic research will determine the mechanisms by which the immune system discriminates between different self and micro-organism associated determinants. We will address the structural and biochemical basis for operation of an immune molecule called tapasin and unravel the basis for how some viruses escape the function of this molecule, thus allowing their immune evasion. We will also explore the use of modified small proteins called peptides in a humanized model of gluten hypersensitivity resembling that of Celiac disease. The molecular basis of the natural human immune system's capacity to recognise and reject grafts will be examined. This complements work aimed at improving the prediction of clinical graft rejection in transplantation. Dendritic cells play a central role in immunity, responsible for capturing material, whether from micro-organisms or self tissues, and presenting it to cells of the immune system. Our program will study the development and immunological function of the different dendritic cell subtypes. We will determine the relative contribution of each to the maintenance of immune tolerance and to the induction of immunity to several pathogens, including herpes simplex virus and malaria. Novel dendritic cell surface molecules that we have discovered will be tested for their ability to enhance the effectiveness of vaccines. Overall, this program utilises a broad array of immunological techniques designed to dissect the development and function of various immune system cell types and determine the structure-function relationships between important cell surface molecules involved in immunity.Read moreRead less

Although significant improvements in the management of these cancers have occurred in the past 20 years further research is needed to better understand the molecular mechanisms of disease development and progression. Such research is critical to the better management and ultimate control of these diseases through better treatments and prevention. A multidisciplinary team of cancer researchers at the Garvan Institute of Medical Research, with a 10 year track record of discovery and application of their research into breast and prostate cancer, will employ state-of-the-art research tools to identify new molecules and molecular pathways involved in these diseases. This new information will facilitate the improved management of these cancers through improved assessment of disease progression at the time of diagnosis and the development of new drugs and strategies for treatment and prevention.Read moreRead less

This program aims to understand the molecular and cellular mechanisms controlling airway inflammation, focusing on the cross-talk between scavenger cells at airway surfaces and circulating cells of the immune system. These studies will combine sophisticated mouse models of airway inflammation in the laboratory with clinical investigation and analysis of human tissue. Understanding these processes will translate into better treatments for patients suffering from life-threatening allergy and asthma.Read moreRead less

Antibodies are made by B-cells and are essential for a functional immune system. B cells circulate in the body, searching for signs of infection.

Antibodies are made by B-cells and are essential for a functional immune system. B cells circulate in the body, searching for signs of infection. When they encounter an invader, they mature, with the help of other immune cells, into antibody-producing cells. A small proportion of the cells are set aside as _memory� cells that can rapidly become antibodyproducing cells should the same infection occur again in the future. This is the basis of vaccination. This program aims to understand how a B cell changes into an antibody-producing cell, by studying the genes that are known to be required for the cells to form, or to do their work. We will study animals whose immune systems are under- or over-active, to find out what part of the antibody-producing process is faulty. Using this information, we hope eventually to be able to study diseases of antibody producing cells in humans (as occur in allergy, asthma, rheumatoid arthritis and leukaemia), to be able to identify the precise cause of the problem, and to suggest a therapy. This information may also be used to improve the outcome of vaccination where an enhanced antibody response is desired.Read moreRead less
