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.
Investigating the actions of anti-inflammatory pathways in chronic lung disease. There is an urgent need to develop better drugs for Chronic Obstructive Pulmonary Disease (COPD) as patients become resistant to currently used anti-inflammatory drugs with disease progression. This research will uncover fundamental biology into an important class of anti-inflammatory receptor termed ALX/FPR2. This receptor normally coordinates the clearance of infection and injured tissue and subsequently switches ....Investigating the actions of anti-inflammatory pathways in chronic lung disease. There is an urgent need to develop better drugs for Chronic Obstructive Pulmonary Disease (COPD) as patients become resistant to currently used anti-inflammatory drugs with disease progression. This research will uncover fundamental biology into an important class of anti-inflammatory receptor termed ALX/FPR2. This receptor normally coordinates the clearance of infection and injured tissue and subsequently switches off inflammation. Essential knowledge into why this receptor pathway fails to switch off inflammation will be determined. Furthermore, the development of targeting strategies to this receptor represents an innovative approach to blocking damaging and chronic airway inflammation.Read moreRead less
Elucidating the post-transcriptional regulation of mast cell proteases. Mast cells (MCs) are immune cells that protect against pathogens but may induce deleterious inflammation. MC function is mediated by specific proteases that are pre-formed and stored in granules. 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-tr ....Elucidating the post-transcriptional regulation of mast cell proteases. Mast cells (MCs) are immune cells that protect against pathogens but may induce deleterious inflammation. MC function is mediated by specific proteases that are pre-formed and stored in granules. 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
Building child health through maternal wellbeing. Chronic diseases partly originate in the health & social circumstances of previous generations, during pregnancy, and in conditions during infancy and childhood. This project will draw from three community studies the researcher established to investigate how aspects of women's health affect their children's health and identify new opportunities for disease prevention.

Summary
How innate lymphoid cells regulate mammalian lung development. This project aims to determine the ability of a subset of lung resident immune cells to promote normal lung development through the regulation of stem cells. The lung is constantly exposed to countless environmental challenges including microbes. Mammals’ local immune systems protect the lung from these challenges. This is particularly important in early-life when the lung is still developing. However, impaired lung development affec ....How innate lymphoid cells regulate mammalian lung development. This project aims to determine the ability of a subset of lung resident immune cells to promote normal lung development through the regulation of stem cells. The lung is constantly exposed to countless environmental challenges including microbes. Mammals’ local immune systems protect the lung from these challenges. This is particularly important in early-life when the lung is still developing. However, impaired lung development affects humans and livestock, costing >$3 billion p.a. The intended outcome is to identify basic biological processes involved in normal mammalian lung development, which may lead to strategies to prevent chronic lung diseases in humans and animals.Read moreRead less
Mechanism of action of an anti-inflammatory compound which targets alternatively activated macrophages. The project will study the mechanism by which a novel anti-inflammatory compound, developed by our commercial partner, suppresses the activity of a population of cells known as alternatively activated macrophages. These cells play a key role in driving allergic inflammation, including the inflammation associated with asthma.
Development of microbial bioproducts for the suppression of inflammation. Asthma and inflammatory diseases are serious health problems that result from excessive inflammation. Exposure to bacteria may reduce inflammation. This project will identify the bacterial components that reduce inflammation and develop them into new anti-inflammatory therapies for asthma.
Molecular Mechanisms of NOD signalling. Alterations in NOD1 and NOD2 (nucleotide-binding oligomerization domain containing 1 and 2) signalling have been implicated in various human inflammatory diseases. Therefore, a clear understanding of the molecular signalling pathways is important to gain further insights into potential drug targets for the treatment of these diseases. Using novel experimental approaches, this project aims to identify new members of the NOD signalling pathway. It will test ....Molecular Mechanisms of NOD signalling.

Therefore, a clear understanding of the molecular signalling pathways is important to gain further insights into potential drug targets for the treatment of these diseases. Using novel experimental approaches, this project aims to identify new members of the NOD signalling pathway. It will test the effect of pharmacological inhibition of established molecules such as RIPK2 or IAPs in NOD dependent models for human diseases. Outcomes of this study will be of the utmost interest for the treatment of NOD driven diseases such as Crohn's disease, Blau syndrome or asthma.Read moreRead less
A new approach to reversing and preventing immune-mediated diseases. Chronic inflammatory diseases affect up to 20 per cent of Australians. These diseases reduce wellbeing and life potential and shorten lifespan. This project addresses the urgent need for effective therapies and focuses on developing strategies for disease cure and prevention.
Elucidating the roles of steroid receptors in mitochondria. This project aims to elucidate the roles of newly discovered steroid receptors in the functions of mitochondria. The project will characterise their impact on cellular respiration, oxidative stress, and the induction of inflammation. By defining these processes in the healthy state and in response to common environmental challenges of infection and smoke exposure, the project will characterise the fundamental biology of entirely new pro ....Elucidating the roles of steroid receptors in mitochondria. This project aims to elucidate the roles of newly discovered steroid receptors in the functions of mitochondria. The project will characterise their impact on cellular respiration, oxidative stress, and the induction of inflammation. By defining these processes in the healthy state and in response to common environmental challenges of infection and smoke exposure, the project will characterise the fundamental biology of entirely new processes of how normal body hormones and administered steroids may function. This may eventually lead to new and more effective ways to control inflammation that will have significant benefits to mammalian health and improve health care and agriculture outcomes.Read moreRead less
