Summary
In response to viruses, the immune system produces interferons. Interferons fight infections but can also contribute to autoimmune diseases, where the body mistakenly attacks itself. Production of interferons is regulated by DUBA. Thus DUBA is an attractive target for therapies against viruses or autoimmune diseases. To achieve this, it is important to understand not only the mechanism of action of DUBA, but also what other roles DUBA may play in the immune system. We can study these in mice.
Dengue Virus NS1 Protein As A Mediator Of Pathology

Summary
Dengue virus is an increasing problem in the tropical world, with estimated infection of more than 300 million people annually. Severe dengue disease can cause life-threatening bleeding and shock. Our project investigates the basis for the pathology of the disease. We have found that a viral protein termed NS1 binds to a receptor on immune cells and leads to production of inflammatory proteins which can promote vessel leakage. We will investigate drugs blocking this, in a disease model.
Defining The Role Of The Novel Gene MUL1 In Antiviral Innate Immunity

Summary
Uncontrolled immune responses can clinically manifest in chronic inflammatory disorders. Viral infections carry a significant global health burden, causing acute and chronic inflammation. This study will characterize a novel regulator of anti-viral immune responses. Understanding the regulation of infection models may provide the means of manipulating immune responses to control infections and provide better health outcomes.

Summary
The innate immune system acts rapidly to limit infection of invading pathogens. The interaction and recognition of pathogens such as viruses by the innate immune system, is of importance to understand why particular pathogens induce disease.
Inflammasome Sensors And Immune Protection Against Tumorigenesis

Summary
Intestinal cancer is a leading cause of death in Australia and worldwide. Defects in the immune system can lead to the development of intestinal cancer. In this project, we will investigate the critical role of an immune sensor in inhibiting the development of intestinal cancer. This project will provide new insights into the interplay between the immune system and cancer biology and will potentially inform the development of new immunotherapies.
Cells recycle old components using a system called the proteasome. Some people are born without parts of the proteasome, and they suffer from a disease associated with inflammation. We have identified the molecular trigger for this inflammation. Our findings are also relevant for patients being treated with proteasome inhibitors. In some of these diseases, such as lupus, inflammation can be a side-effect of proteasome inhibitor therapy, and we can now reduce this and make the treatments safer.
NOD-like Receptors And Severe Malaria: Do Inflammasomes Mediate Immunopathogenesis?

Funding Amount

Summary
Our immune system is very effective in preventing disease. But sometimes our immune cells overreact and actually make us sick. Recently, a new component of the immune system, the inflammasome, was discovered. Overreaction of the inflammasome can result in fever, inflammation, and even death. This project will investigate whether inflammasome overreaction exacerbates diseases as diverse as malaria and cancer, and whether drugs that inhibit the inflammasome can help cure these and other diseases.
The Role Of DNA Sensing In The Pathogenesis Of Colorectal Cancer

Summary
Colorectal (bowel) cancer is a leading cause of death in Australia and worldwide. The ability of the body to detect DNA from damaged or dying cells in the gut is an important part of the healing process. This response also provides protection against colorectal cancer. In this project, we investigate how a DNA sensor prevents the development of intestinal tumours. This project will lead to new ways to fight cancer in humans.
Amyotrophic Lateral Sclerosis (ALS) is a progressively fatal neurodegenerative disease characterized by aggregates of a protein called TDP-43. ALS also features the presence of several inflammatory cytokines in the central nervous system. In this project, we will study how TDP-43 abnormally mislocalizes within cells, releasing mitochondrial DNA and triggering a novel pathway of inflammation. We propose that targeting this pathway could lead to new treatments for ALS.

Australia leads the world in the adoption of speech recognition technology but sadly lags in the development of the fundamental advances in the area. This research will help propel Australia to the forefront of new innovations in speech recognition technology and contributions to fundamental science. Our project will provide an excellent training ground for graduate students and researchers, with the real possibility of significant commercial benefit to the nation. The deployment of our system in the community will greatly enhance the defence and police forces ability for surveillance and security, and will provide new assistive aids to improve the quality of life and safety for the elderly and disabled.Read moreRead less
