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
Investigating the atomic structure of an immune cell inhibitory receptor. T cells play a key role in the adaptive immune system, whose reactivity must be controlled to prevent aberrant reactivity. Central to the function of T cells is the T cell antigen receptor, and a host of co-stimulatory molecules, co-receptors and inhibitory receptors. This proposal, in partnership with Immutep Ltd, aims to gain a basic understanding of the structure and function of a key inhibitory receptor found on T cel ....Investigating the atomic structure of an immune cell inhibitory receptor. T cells play a key role in the adaptive immune system, whose reactivity must be controlled to prevent aberrant reactivity. Central to the function of T cells is the T cell antigen receptor, and a host of co-stimulatory molecules, co-receptors and inhibitory receptors. This proposal, in partnership with Immutep Ltd, aims to gain a basic understanding of the structure and function of a key inhibitory receptor found on T cells, termed the Lymphocyte activation gene-3 (LAG-3). The proposal utilises a combination of cellular immunology and structural biology to gain insight into the form and function of the LAG-3 molecule. Ultimately this fundamental knowledge can be used by the biotechnology industry.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

This knowledge benefits basic and applied biology and is relevant to industries/projects utilizing living cells as nutrient supports cell survival and proliferation.Read moreRead less
Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods.

Mitochondrial damage is linked to a wide spectrum of human diseases, from devastating syndromic illnesses to neurodegeneration and autoimmunity. This project is focused on 1) how stresses such as cancer therapy or infection cause mitochondrial damage, and 2) understanding the biological processes that are triggered inside the cell as it tries to recover. It will give a much greater understanding of mitochondrial damage at the microscopic level, and has the potential to unlock new avenues of investigation into the causes of inflammatory and immune disorders.Read moreRead less
