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

Summary
Fluorescence microscopy with optical tweezers: imaging cellular responses. Life relies on the ability of our cells to receive and respond to signals with pinpoint accuracy, involving both chemical and mechanical signals. This equipment will allow scientists to expose cells to both types of signals and measure the response at an unprecedented level of accuracy for the first time.
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.
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.

A 3-photon imaging system for deep live imaging. This project aims to establish Australia’s first 3-photon microscope system with adaptive optics for deep intravital imaging. This advanced imaging system will enable researchers to investigate the biology of cells and tissue structures in a wide range of organs and engineered tissues, to a degree not possible with existing technology. This project will capitalise on advanced laser, microscope and adaptive optics technologies with the expected out ....A 3-photon imaging system for deep live imaging. This project aims to establish Australia’s first 3-photon microscope system with adaptive optics for deep intravital imaging. This advanced imaging system will enable researchers to investigate the biology of cells and tissue structures in a wide range of organs and engineered tissues, to a degree not possible with existing technology. This project will capitalise on advanced laser, microscope and adaptive optics technologies with the expected outcomes to include the generation of new knowledge of major biological systems, including the immune system and the nervous system. This will provide significant benefits to fundamental interdisciplinary research into immunology, infectious disease, neuroscience, mechanobiology and engineering.Read moreRead less
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
New guardians of the mucosa: Molecular characterisation of M cell biology. We aim to completely define the cellular and molecular biology of gut and lung M cells for the first time. We will elucidate how they develop, are regulated and function at a molecular level, and how M cells maintain normal gut and lung tissues and induce immune responses to protect against microbial challenges. In the future, the new insights will be essential pre-requisites for the development of mucosal-based intervent ....New guardians of the mucosa: Molecular characterisation of M cell biology. We aim to completely define the cellular and molecular biology of gut and lung M cells for the first time. We will elucidate how they develop, are regulated and function at a molecular level, and how M cells maintain normal gut and lung tissues and induce immune responses to protect against microbial challenges. In the future, the new insights will be essential pre-requisites for the development of mucosal-based interventions and vaccines that protect the gut and lung from infectious and inflammatory issues. The harnessing of effective immune responses to control such challenges, are of enormous fundamental and long-standing biological interest, and are amongst the most important areas of current scientific research.Read moreRead less
Lifespan-dependent molecular shaping of the T cell receptor repertoire. Mammals have an intricate and highly complex immune system, whose function alters throughout life. Why and how this occurs is very unclear however, yet remains a crucial question. This project aims to provide fundamental knowledge on how the human lifespan shapes specific T cell receptors and determine molecular mechanisms underlying gain-of-function and loss-of-function during immunologically distinct phases of life.

Why and how this occurs is very unclear however, yet remains a crucial question. This project aims to provide fundamental knowledge on how the human lifespan shapes specific T cell receptors and determine molecular mechanisms underlying gain-of-function and loss-of-function during immunologically distinct phases of life. This project will provide analysis of multi-dimensional, high throughput datasets to identify fundamental links between the transcriptional landscape and TCR signatures across human lifespan, thus will significantly answer key immunological questions in the field.Read moreRead less
