Summary
Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens.

Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. However, many infants who wheeze with viral infections, especially in the first year of life, do not develop allergies in later life, raising the possibility that they did not have the same type of asthma as those whose symptoms persist. This project will study the effects of viral infections on lung function to determine whether particular types of virus can have detrimental effects of lung function lasting for years. We will also examine whether the age at which the infection occurs and the severity of the infection influence the long-term outcome. The project involves studying infants during the recovery phase of respiratory viral infections, older children years after documented infections and experimental animal models that have been infected under controlled conditions. By determining whether respiratory viral infections can have long-term effects on lung function that can mimic asthma, we will advance our understanding of how asthma develops. In addition, specific treatment and preventative strategies could then be developed to prevent these long-term abnormalities, instead of relying on asthma medication (especially inhaled corticosteroids) as is the current practice. Preventative strategies could include encouraging the development of specific vaccines.Read moreRead less
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development

Funding Amount
$520,520.00
Summary
Chikungunya virus (CHIKV) is a globally widespread mosquito-borne alphavirus capable of causing considerable human morbidity and mortality. With no CHIKV vaccine or antiviral available this proposal aims to develop a live attenuated CHIKV vaccine, rationally designed by investigating the host cell nucleolar trafficking of CHIKV capsid protein. This vaccine has the potential to provide cross-protection against additional arthritogenic alphaviruses endemic to Australia such as Ross River virus.
Arbovirus Activation And Modulation Of NLRP3 Inflammasome

Summary
This project aims to establish how mosquito borne viruses such as Ross River and dengue viruses interacts with the human host to cause disease, including how the virus evades the host’s immune response to persist and cause disease for prolonged periods. Knowing how differences in the virus and the host’s immune system interplay to cause asymptomatic to severely disabling disease will assist in devising new treatments and prevention programs to lessen the impact of these diseases in Australia.
Rhinovirus impairs physiological and immunological lung development and causes exacerbation of allergic airways disease. Rhinovirus (RV) infections account for around 90 per cent of asthma exacerbations, yet the mechanisms behind this are unknown. This project will use mouse models to study the effects of early life RV infection and allergic sensitisation on respiratory and immunological development, with the expectation that early life RV infection disrupts anitgen presenting cell function.
Determining how calcium regulates mitochondrial function in models of cardiomyopathy. Heart failure is the leading cause of death in Australia. This project will determine the mechanisms by which the failing heart is associated with disorganisation of the cell and poor energy supply so that interventions aimed at reducing the development of heart failure can be developed.

However, the scarcity of sophisticated statistical techniques to deal with the complicated problems inherent in genetic investigations of complex diseases is currently the critical factor limiting the success of human gene discovery programs. Statistical genetic methodology is currently one of the fastest developing areas of epidemiology. In information-intensive' areas such as genetic epidemiology, genomics, and proteomics, there is a high demand for data analysis and statistical skills. WA has some world class expertise in statistical science, both in academia and in industry. However, this expertise has not yet been applied in a system way to genetic data analysis. We propose to undertake advanced methodological research in statistical genetics and bioinformatics, to produce easy-to-use and accessible software tools and resources that allow methodological advances to be accessed by the Australian research community, and to apply our new methods and tools both to specific disease research and to the developing human genome epidemiology (HuGE) enterprise in WA. These new initiatives in methodological research will draw together a number of currently separate research strands and will provide new tools and resources that will allow applied Australian programs to improve the efficiency of their research into the causes of important. Methodological development in both bioinformatics and statistical genetics are recognized international areas of need.Read moreRead less
Detection and viability of waterborne pathogens using a gut-on-chip. This project aims to resolve a significant problem for water utilities. Microbial pathogens Cryptosporidium, norovirus and adenovirus are the main public health concern for drinking water in developed nations. Water monitoring is limited by the lack of fast, reliable detection methods and viability assays for these pathogens.

Mechanisms Underlying Growth, Lineage Commitment And Differentiation Of Liver Progenitor Cells

Funding Amount

Summary
Liver disease is a serious health problem. Viral hepatitis, obesity and alcohol can result in end-stage liver disease. Organ transplant is the only treatment available. A widening gap between organ donations and recipients mandates alternative treatments are developed. Cell transplantation and artificial liver devices are alternatives which can use liver progenitor cells. We will investigate how factors grow and convert them into liver cells for treating liver disease patients.
Domestic air quality: towards the setting of guidelines. Air quality standards have been developed to protect human health. Although people spend most of their time indoors there are no standards and only a few guidelines for indoor air pollution (IAP). The aim of this study is to investigate the levels of IAP that may worsen asthma in children. Childhood asthma will be used as a health indicator due to its high prevalence, cost to the healthcare system and implications for respiratory morbidity ....Domestic air quality: towards the setting of guidelines. Air quality standards have been developed to protect human health. Although people spend most of their time indoors there are no standards and only a few guidelines for indoor air pollution (IAP). The aim of this study is to investigate the levels of IAP that may worsen asthma in children. Childhood asthma will be used as a health indicator due to its high prevalence, cost to the healthcare system and implications for respiratory morbidity in adult life. We expect to identify levels of IAP that will represent a health risk as well as the factors that may contribute to increased IAP in homes.Read moreRead less

Summary
This program focuses on understanding the development of immune response to viruses and other infectious agents using a broad array of techniques to dissect the function of various immune cell types and to explore the relationship between structure and function of important cell surface molecules. These studies will improve our ability to design new generation vaccines for combating infectious diseases, controlling cancer, or limiting autoimmune diseases like diabetes.
