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 ....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 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
The immune system plays an important role in protecting the host from viral and bacterial infections, and inhibits cancer onset and progression. Unfortunately the immune system can sometimes lose specificity and attack the host resulting in autoimmune diseases such as diabetes.

This research team has played a vital role in characterising the specific activities of immune cells and the associated factors.

While current influenza vaccines blunt winter epidemics, they must be updated frequently to keep up with virus mutation and they do not protect against pandemics caused by new flu viruses (such as bird flu). This program will define how flu virus interacts with the immune system to generate immunity mediated particularly by “killer” T cells. We will use this knowledge to develop and evaluate vaccines that induce long-lasting T-cell immunity that can protect against both seasonal and pandemic flu ....While current influenza vaccines blunt winter epidemics, they must be updated frequently to keep up with virus mutation and they do not protect against pandemics caused by new flu viruses (such as bird flu).

Members of this team are at the forefront of research into the molecular control of nerve cell production and function in the developing and adult brain. They were responsible, often through collaboration, for many of the major discoveries demonstrating that stem cells in the brain of adult animals can generate new nerve cells; this revolutionised our concept of the brain and opened-up the possibility of therapeutic repair of neural damage through stimulation of a patient?s own stem cells.

They were responsible, often through collaboration, for many of the major discoveries demonstrating that stem cells in the brain of adult animals can generate new nerve cells; this revolutionised our concept of the brain and opened-up the possibility of therapeutic repair of neural damage through stimulation of a patient?s own stem cells. Discovering the molecular mechanisms controlling this process is the goal of the present program. In order to achieve this aim we have formed a team on the basis of considerable past success, as well as future requirements. The team members have the complementary skills to assess all aspects of the problem, including crucial functional and clinical expertise. By combining resources we will position ourselves at the very forefront of the international competition to discover and to evaluate clinically the molecular mechanisms underlying neural repair and regeneration. This is of enormous significance in determining how we best treat stroke, injury and other neurodegenerative diseases in the next 10 years, and will lead to the development of new therapeutics of immense value. The team will use innovative approaches such as cell-sorting to obtain pure populations of stem cells and their progeny in order to identify new therapeutic targets; these will then be validated in animal models of neurological disease. Since team members have previously been involved in progressing molecular discovery to clinical trials, we are also in a good position to exploit these discoveries in partnership with the biopharmaceutical industry.Read moreRead less
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.

Disorders of sexual development (DSDs) are surprisingly common, and often result in infertility, genital abnormalities, gender mis-assignment and long-term psychological trauma. In this Program we will pool our expertise in human molecular genetics, mouse developmental biology and protein chemistry to identify genes important for sex determination and development of the gonads, and discover how they contribute to DSD, in order to improve clinical care to patients with DSD.
