Summary
The ideal way to protect against pandemic bird flu is to vaccinate all Australians as soon as possible after a dangerous strain starts to spread. Current manufacturing technology, which begins by making an infectious virus in chicken eggs, is unable to quickly deliver a mass vaccine to the entire Australian population. The existing process is slow, meaning that it will take several months before enough vaccine is available even to protect personnel working in essential services.

Current manufacturing technology, which begins by making an infectious virus in chicken eggs, is unable to quickly deliver a mass vaccine to the entire Australian population. The existing process is slow, meaning that it will take several months before enough vaccine is available even to protect personnel working in essential services. The product from chicken eggs is rendered safe after manufacture by breaking the virus structure. This make then break strategy reduces vaccine effectiveness meaning that even fewer individuals can be effectively protected per vaccine batch. Recent scientific progress has demonstrated that it is possible to make a non-infectious empty virus shell (a so-called virus-like particle) inside cells. This new product is able to provide full protection against a lethal influenza challenge, when administered nasally. However, these particles are very difficult to purify from contaminants that are packaged into the particles during manufacture in cells. These contaminants can cause an adverse reaction when the product is given to humans, meaning that although the product is effective it remains difficult to mass produce. A manufacturing problem remains. To overcome this manufacturing problem we will seek to assemble vaccine particles in vitro, building the particle from purified protein. Existing technology for manufacturing pure pharmaceutical protein is well-established and safe, and allows mass manufacture of contaminant-free product. This new make don't break manufacturing strategy is similar to that chosen by Merck to deliver a safe and effective vaccine, for cervical cancer, to mass market. Our key aim is to adapt this efficient manufacturing strategy to the manufacture of influenza vaccine. If successful, we will be able to immunize the Australian population using existing national biomanufacturing capability, within weeks of new strain identification, and without the requirement for high-level containment during manufacture.Read moreRead less
Chimeric Virus-like Particles (VLPs) Displaying H1, H3 And H5 Haemagglutinins - Construction And Immunogenicity

Summary
Virus-like particles (VLPs) provoke strong immune responses in the body. We have developed a novel VLP system that allows the production of VLPs containing foreign vaccine antigens of much larger size than previously possible, and have shown that these VLPs provoke strong immune responses in mice without the use of adjuvants. The capacity of these VLPs is large enough to accommodate the most important vaccine antigen of influenza, the haemagglutinin (HA) molecule.

We have developed a novel VLP system that allows the production of VLPs containing foreign vaccine antigens of much larger size than previously possible, and have shown that these VLPs provoke strong immune responses in mice without the use of adjuvants. The capacity of these VLPs is large enough to accommodate the most important vaccine antigen of influenza, the haemagglutinin (HA) molecule. We will test whether VLPs can be produced containing each of the three most important HA types _ H1 and H3 that are currently circulating in man, and H5 (avian) that is considered a pandemic threat. VLPs will be tested for their ability to induce neutralizing antibody and cellular immune responses in mice, and for their ability to protect ferrets from influenza infection. If successful, the HA-VLP system would provide a method for the rapid production of new influenza vaccines using large-scale fermentation technology as for hepatitis B and many other vaccines, rather than eggs or cell culture as used for current influenza vaccines.Read moreRead less

In the existing models, mesothelioma cells that have been grown in the laboratory are transplanted into animals by injecting the cells under the skin. Different cell lines with different properties are used in different experimental protocols. This application will fund the establishment of a central resource to maintain and distribute these cell lines. In addition, we describe a new transgenic mouse model in which mesotheliomas are rapidly induced in the peritoneal cavity after exposure to asbestos, recreating the natural tumour development much more accurately. These mice have been engineered to express the cancer causing protein of a monkey virus (SV40 large T antigen) in their mesothelial cells because it has been suggested that the virus has a role in the development of mesothelioma. This application also seeks funding to use the MexTAg mice to test the usefulness of different therapies for the prevention or treatment of mesothelioma. These animals give us the ability to investigate the disease in a more realistic environment than previous models. In parallel collaborative studies with other groups investigating different aspects of the biology of this cancer, we plan to analyze the earliest changes in the development of the disease and search for early markers using proteomics and gene expression studies. We anticipate that this model will generate information more directly relevant to understanding the human disease and will provide essential experimental data for clinical trials.Read moreRead less

This project will develop a culturally appropriate and evidenced based intervention to break the cycle of ongoing grief, mental illness, alcohol and other drugs and violence. The project will proceed in a number of interrelated phases including extensive community consultations and a baseline survey. The project will then implement and evaluate an intervention program that provides a community and individual program that adopts evidence-based approaches and modifies them to be acceptable within Aboriginal communities. These interventions aim to break the cycle of violence and mental health problems by teaching adaptive skills to reduce violent behaviours and by providing mental health interventions that reduce disorders that contribute to violence.Read moreRead less

Obesity is a rapidly escalating, worldwide epidemic. Many countries recognise the need to prevent obesity but there is insufficient evidence about what interventions work.

Many countries recognise the need to prevent obesity but there is insufficient evidence about what interventions work. The Pacific Obesity Prevention in Communities (OPIC) Project will provide data on the effectiveness of a range of interventions to prevent obesity among young people in Fiji, Tonga, New Zealand and Australia. Prevention research is particularly required in countries such as Fiji and Tonga because their prevalence of obesity is extremely high. The interventions used in this project will be culturally appropriate and include at least 1000 young people in each intervention group. The outcomes of this project will be applicable to both low- and high-income countries. This project will lead to a greater understanding of the socio-cultural, policy, and economic contexts and provide crucial evidence for public health action to prevent obesity.Read moreRead less

Genomic And Proteomic Profiling Of Dendritic Cell Heterogeneity

Funding Amount
$1,971,250.00
Summary
Dendritic cells (DC) present antigens to T cells and regulate immunity and tolerance. DC are heterogeneous, comprising seven functionally distinct subsets. We will use genomics and proteomics to identify the plasma membrane and endosomal proteins that underpin this functional heterogeneity. Such proteins are potential targets for improved protocols of vaccination and prevention of autoimmunity. This project will thus provide further opportunities for high-quality research and commercialisation.
Phosphoproteomics: Metabolic And Exercise Signalling Markers For Sedentary And Trained Individuals

Funding Amount
$1,222,500.00
Summary
It is widely recognized that diet and exercise have a major influence on the health and fitness. Sedentary lifestyles predispose people to obesity and the early development of age onset diseases. In the past decade we have gained considerable insight into the regulatory links between exercise and metabolism particularly involving the AMPK signalling pathway. This project is concerned with the phosphoproteome of trained and untrained skeletal muscle, fat and erythrocytes as a marker of fitness.
