These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-transcriptionally regulate the production and storage of these proteins. The project aims to identify the RNA binding proteins, microRNAs and other novel factors that also regulate them. This is expected to elucidate the post-transcriptional mechanisms of regulation of MC proteases.Read moreRead less

Summary
Mesial temporal lobe epilepsy, the most common form of drug-resistant epilepsy in adults, is a progressive neurodegenerative condition for which there is currently no effective disease modifying treatment. This proposal will explore whether co-morbid stress accelerates disease progression in MTLE, and whether targeting stress pathways by medical and environmental manipulations can mitigate against this.

Summary
The liver is important for both digestion and immunity. Given these opposing functions, the liver must exert control points that prevent the immune system from recognising food products. We have now identified a new molecular target that controls the development of immune cells in the liver.
Regulation of lung immune-epithelial networks sensing environmental change. This study aims to uncover how lung epithelial cells engage with immune cells and determine their cellular and molecular wiring to ensure homeostatic maintenance and essential repair processes of lung tissues. Maintenance of lung epithelial-immune networks is essential to maintain normal lung tissue structure and function, and to induce immune responses to protect against microbial challenges or inhaled potentially toxic ....Regulation of lung immune-epithelial networks sensing environmental change. This study aims to uncover how lung epithelial cells engage with immune cells and determine their cellular and molecular wiring to ensure homeostatic maintenance and essential repair processes of lung tissues. Maintenance of lung epithelial-immune networks is essential to maintain normal lung tissue structure and function, and to induce immune responses to protect against microbial challenges or inhaled potentially toxic substances. Understanding this molecular program of epithelial-immune cell-mediated sensing/repair will be essential to understand how tissue-repair processes can be driven in the lung, an organ critical for respiration and thus life.Read moreRead less

This project aims to describe and identify the effects of Australian natural disasters – such as the Black Saturday bushfires and the Brisbane floods – on important microeconomic outcomes, including health, education and employment. Natural disasters have profound economic and social effects on individuals and communities. This project intends to bring evidence on how disasters affect individuals and how the effects can be lessened. The project expects to inform policy-makers on these critical issues by analysing field, survey and administrative data on individuals before and after past disasters.Read moreRead less
Revealing the evolutionary and ecological dynamics of avian influenza virus. This project aims to understand how avian influenza virus (AIV) emerges, evolves and spreads in wild birds. AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well a ....Revealing the evolutionary and ecological dynamics of avian influenza virus. This project aims to understand how avian influenza virus (AIV) emerges, evolves and spreads in wild birds. AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well as the risk for future viral emergence. Using sampling sites in Australia and Antarctica, it plans to investigate AIV diversity, the evolutionary dynamics of AIV in wild birds and poultry, and the role played by environmental transmission in AIV ecology.Read moreRead less
The macrophage nucleus - its form and function during migration in vivo. As cells migrate through tissues, they encounter complex, 3-dimensional environments that provide cues to guide them and present obstacles in their path. This project focuses on macrophages, a large immune cell capable of both amoeboid and mesenchymal modes of migration. The nucleus is the largest organelle and its bulk and stiffness must be managed as migrating cells travel through constrictions.

As cells migrate through tissues, they encounter complex, 3-dimensional environments that provide cues to guide them and present obstacles in their path. This project focuses on macrophages, a large immune cell capable of both amoeboid and mesenchymal modes of migration. The nucleus is the largest organelle and its bulk and stiffness must be managed as migrating cells travel through constrictions. The project uses specialised high-end microscopy and genetic methods to examine how the nucleus of migrating zebrafish macrophages deforms, repositions and is restructured during migration in living tissues, and how this influences macrophage locomotion. The goal is to provide fundamental insights into the cell biology of macrophage migration.Read moreRead less
Nuclear plasticity during neutrophil migration and function. This project aims to discover how nuclear shape affects neutrophil function. Cell migration needs overall cellular plasticity and plasticity of internal structures such as the nucleus. The neutrophil, one of the most peripatetic cell types, has a specialised lobulated nucleus, thought to facilitate its mobility and function. Using zebrafish reporter lines that concurrently display the nucleus and cytoplasm, this project will display th ....Nuclear plasticity during neutrophil migration and function. This project aims to discover how nuclear shape affects neutrophil function. Cell migration needs overall cellular plasticity and plasticity of internal structures such as the nucleus. The neutrophil, one of the most peripatetic cell types, has a specialised lobulated nucleus, thought to facilitate its mobility and function. Using zebrafish reporter lines that concurrently display the nucleus and cytoplasm, this project will display the dynamic plasticity of neutrophil nuclei during neutrophil migration and function in vivo. This project seeks to use the spatiotemporal resolution of a lattice light sheet microscope to examine this further, and explore its effect on neutrophil function. The project seeks to establish morphological and mechanical principles applying not just to neutrophils, but to all migratory cell types.Read moreRead less

This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infection pressure settings, as a chemo-preventative for these disease agents. Tropical regions spanning northern Australia and Southern Asia are highly conducive to a plethora of canine vector-borne and parasitic pathogens that cause significant morbidity and mortality in dogs. Many of these agents also pose a risk to public health. The outcomes will be directly translated to best-practice guidelines for the advancement of companion animal (and indirectly human) health and welfare.Read moreRead less
