Despite recent advances in therapeutic options, chronic viral infections, including infection with hepatitis C virus and hepatitis B virus, continue to be a significant cause of morbidity and mortality in Australia and affecting hundreds of millions of people worldwide. This R&D program aims to develop a cheaper drug formulation that is easier to deliver and more stable for transport to remote areas.
The immune system must be tightly regulated to make sure that it makes the right response to effectively fight off infection whilst avoiding inappropriate responses that cause damage such as in autoimmunity, inflammation or allergy. This project studies patients who have genetic defects that affect their immune systems and make them susceptible to infection and/or harmful immune responses. This will reveal some of the critical signals that maintain immune control.

Summary
Antibody producing cells and memory B cells are crucial to successful vaccination and provide protection against infections. Development of both is controlled by factors that regulate gene activity, but the same factors are also involved in the development of blood cancers. Using new research tools and assays we will uncover the roles of the Id and E protein family of factors implicated in these processes, which may help in the design of new vaccination strategies and the treatment of blood canc ....Antibody producing cells and memory B cells are crucial to successful vaccination and provide protection against infections.

The immune system usually rapidly responds to eradicate infectious pathogens. However patients with mutations in the gene PI3KCD, which is important for delivering messages within immune cells, are unable to control infections with some bacteria and viruses. We will study the effects of these mutations on B cells, the immune cells produce antibodies that bind to and remove pathogens from our body. This will explain some of the clinical features of this disease and reveal potential new treatments
The cell types of the blood, such as red and white blood cells, are produced in the bone marrow from a rare stem cell. The stem cell uses a handful of important master-regulatory genes that act in a hierarchy to promote the blood cell differentiation process. This research aims to understand how these master-regulators function in isolation and together in producing the white blood cells that are required for our immune response to microbes, vaccination and to prevent cancer.

Summary
During the onset of cancer, the orientation of cells is lost. My research project aims to determine the cellular and molecular basis by which proteins responsible for the orientation of cells are involved in leukaemia. Additionally, my work will investigate whether or not all proteins are equally distributed during cell division in B cell development, and will provide a platform for further investigation into how protein distribution might orchestrate fate decisions during development and leukae ....During the onset of cancer, the orientation of cells is lost.

The lymphocyte plays a vital role in our immune defence. When lymphocytes encounter a foreign invader, such as a virus, they make a series of decisions that influence the strength, type, and longevity of the immunity created. This program aims to understand how lymphocytes make decisions at the molecular level that affect cell and whole of system level behaviour. We aim to improve vaccines and understand diseases such as allergy, lupus, arthritis and leukaemia to develop novel therapies.

Summary
Hospitalisation and death rates from influenza are high in the Indigenous population. There is an urgent need for one-shot universal vaccine that protects against seasonal and pandemic strains. T cells recognising conserved viral regions can elicit such protection. As T cells are restricted by proteins called HLAs, variable between different ethnicities, we will define T cell regions and their HLA restrictions in the Indigenous population to propose strategies for universal T cell-based protecti ....Hospitalisation and death rates from influenza are high in the Indigenous population.

Understanding Immunity To Influenza Viruses In The Indigenous Population

Summary
Hospitalization rates and mortality from influenza are greatly increased in the Indigenous Australian population. As current vaccines are highly strain-specific, there is an urgent need for a one-shot universal vaccine that protects this vulnerable group against seasonal and pandemic influenza. Immunity provided by T cells is long-lasting, cross-protective and can prevent severe disease. Our findings will inform the design of effective T cell-based influenza vaccines for Indigenous populations.

Summary
Knowledge of how virus-infected cells are detected by the bodyÍs immune system is fundamental to our understanding of virus infections and attempts to improve vaccines. We know that many proteins are displayed during virus infection but until now, the precise details of this display have only been worked out for very few proteins, studied one at a time. In this project we will apply cutting-edge technology to gain the first holistic view of how a virus-infected cell looks to the immune system.
