Medical trust is vital to building positive healthcare engagement and improving health outcomes, yet is poorly understood in non-Western contexts. Focusing on crises of trust related to type 2 diabetes and COVID-19 interventions in the Pacific, this collaborative project aims to examine the social and cultural dynamics of medical (mis)trust in Vanuatu, Fiji, and Samoa. Providing the first cross-cultural study of medical trust, an international team of researchers will generate interdisciplinary scholarly outputs, policy resources and a documentary film. Findings will assist healthcare professionals and communities strengthen trust relationships and ultimately achieve improved health engagement and delivery in the Pacific and beyond.Read moreRead less
Understanding the life and death of Mucosal-associated invariant T cells. Cell death of naïve T cells in lymphoid organs is well-understood. However, T cells only gain their function upon activation, and how activated T cells regulate their life or death remains unclear. Mucosal-associated Invariant T (MAIT) cells are abundant in non-lymphoid tissues as key local players in immunity, and share some features of activated conventional T cells. This project aims to define how MAIT cell survival and ....Understanding the life and death of Mucosal-associated invariant T cells. Cell death of naïve T cells in lymphoid organs is well-understood. However, T cells only gain their function upon activation, and how activated T cells regulate their life or death remains unclear. Mucosal-associated Invariant T (MAIT) cells are abundant in non-lymphoid tissues as key local players in immunity, and share some features of activated conventional T cells. This project aims to define how MAIT cell survival and death are controlled. It combines methods we developed to track MAIT cells in vivo with expertise in cell death analysis. This project is expected to elucidate the complex mechanisms controlling MAIT cell survival/death and increase our fundamental understanding of cell death mechanisms of activated T cells.Read moreRead less
Making muscle: molecular dissection of membrane domain formation. For a muscle to contract efficiently in response to an electrical signal it requires the formation of an extensive system of hollow membranous tubules through which the signal can be propagated. This proposal addresses the molecular mechanisms involved in the formation of this tubule system in skeletal muscle. This project will develop cell biology in a whole organism rather than a cell culture system and provide a new framework f ....Making muscle: molecular dissection of membrane domain formation. For a muscle to contract efficiently in response to an electrical signal it requires the formation of an extensive system of hollow membranous tubules through which the signal can be propagated. This proposal addresses the molecular mechanisms involved in the formation of this tubule system in skeletal muscle. This project will develop cell biology in a whole organism rather than a cell culture system and provide a new framework for Australian and international cell biologists. It will generate new knowledge, train young Australian scientists, help build international collaborative networks and engage the public outside the research community.Read moreRead less
The core inflammasome as a model for caspase activation. This project aims to change the paradigm for the structure of the active inflammasome. Inflammasomes activate caspases, enzymes central to cell death and inflammatory processes. The current concept of inflammasomes is that caspases are recruited into a single massive protein complex seen as a “speck” in the cell. This project proposes the speck is a terminal stage, after the major enzymatic activity is over. This project aims to purify sma ....The core inflammasome as a model for caspase activation. This project aims to change the paradigm for the structure of the active inflammasome. Inflammasomes activate caspases, enzymes central to cell death and inflammatory processes. The current concept of inflammasomes is that caspases are recruited into a single massive protein complex seen as a “speck” in the cell. This project proposes the speck is a terminal stage, after the major enzymatic activity is over. This project aims to purify smaller early stage inflammasome complexes, for structural analysis. The outcome will be a clearer understanding of processes of caspase activation and inflammasome formation. This will provide significant benefits, such as improve our understanding of processes of cell death and innate immunity, and train students.Read moreRead less
Applications-oriented elucidation of germination triggers for Emu Bush seed.

The anticipated project outcomes aim to develop new technologies for efficient and mass production of Emu Bush seedlings. The outcomes will improve land restoration by increasing plant diversity and reducing establishment costs, and will also provide the nursery industry with novel products for home gardens. The intended project benefits are to increase the diversity of Australian native plants used for restoration and ornamental purposes and to promote the conservation of species in this plant family and its genetic diversity.Read moreRead less

Basic biochemistry and the metabolic regulation of proliferation remain as the fundamental building blocks of knowledge in cell biology that have enabled breakthrough advances in biology and medicine. Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyamines, as we have discovered that polyamines are regulated by iron at 2-major levels, involving >10-key polyamine pathway proteins. This proposal represents first-in-field studies specifically designed to dissect mechanisms involved in this relationship. Our Central Hypothesis is that iron regulates polyamine metabolism.Read moreRead less

ARC Research Hub for Integrated Device for End-user Analysis at Low-levels. This hub aims to improve detection of biological materials by building a portable device for rapid, time-critical detection of low-abundance molecular and cellular analytes. It is expected that the resulting technologies would be used at medical points of care, ordinary workplaces and centres of activity to test for tiny levels of targeted molecules. The initial focus would be early diagnosis of disease and point-of-care drug testing for humans and animals, but the technology platform could be used to sample food and environmental toxins. The hub expects these disruptive technologies will make Australian biotechnology, diagnostics, veterinary, agribusiness and manufacturing firms globally competitive.Read moreRead less
