This information is critical for the development of potent antiviral vaccines that are effective from the newborn period without inducing autoimmunity. It will also provide novel insight into the way T regulatory cells can be manipulated both to dampen immunity, which can be used to develop strategies to reduce immune mediated disease and limit transplant rejection.

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

The scientific advances that will be possible with the acquisition of these complementary cutting-edge instruments will enhance the research outputs of all investigators using it. Projects where investigation of either suspended or adherent live cells is used to elucidate basic life processes of eukaryotic cells across all species of animals, including the investigation of both normal and abnormal function, will be immeasurably enhanced by both the qualitative and quantitative statistical information about these processes that is generated by this instrumentation. This in turn will inform new approaches to improve and maintain the health of both humans and animals.Read moreRead less

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.

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

Cytometry by time-of-flight mass spectrometry platform for the Advanced Cytometry Facility: overcoming fluorescence spectral barriers to truly multiparametric cytometry by mass spectrometry: This project will provide a flow cytometer capable of analysing single cells by time-of-flight mass spectrometry. Antibody labels for cell components will enable measurement of up to 100 parameters/cell. Developing analytical and modelling algorithms like Spanning tree Progression of Density normalised Events (SPADE), this project will aim to map the relationships of various unelucidated cell lineages, via functional pathway connections. New pathways thus revealed will enable elaboration and use of novel specific molecules in perturbational analyses to confirm and further enhance the understanding of these highly intricate, basic relationships. This will provide unparalleled insight, both into early development of stem cells and mechanisms of maintenance of homeostasis in differentiated cells.Read moreRead less
Real-time imaging of the initiation of adaptive immunity in vivo. Understanding the first few hours of an immune response is fundamental to understanding how the human immune system functions. The immune system mounts our responses to infectious diseases, but can also cause autoimmune disease, allergy, and organ graft rejection. We will study how naive antigen-specific T cells first contact antigen in lymph nodes using 2-photon intravital microscopy. The research has the potential to change the ....Real-time imaging of the initiation of adaptive immunity in vivo.

We will study how naive antigen-specific T cells first contact antigen in lymph nodes using 2-photon intravital microscopy. The research has the potential to change the way we think about the clonal selection of lymphocytes, the fundamental theory underlying our understanding of the immune system.Read moreRead less
CD4 T cell programming by neonatal and early-life infection. T lymphocytes (T cells) are white blood cells that play a critical role in protecting the body from infection. Before T cells can function they need to be programmed so that they can specifically respond to an infectious agent (a type of bacteria or virus). Inappropriate programming can lead to disease. Whether T cells respond to an infectious agent or foreign substance in a protective or destructive manner may critically depend on the ....CD4 T cell programming by neonatal and early-life infection. T lymphocytes (T cells) are white blood cells that play a critical role in protecting the body from infection. Before T cells can function they need to be programmed so that they can specifically respond to an infectious agent (a type of bacteria or virus). Inappropriate programming can lead to disease. Whether T cells respond to an infectious agent or foreign substance in a protective or destructive manner may critically depend on the age that an individual first encounters the infection. Our project will identify critical periods in life that direct T cell programming to subsequent protective or destructive responses, providing new insights into the developing immune system that may be exploited to treat disease or develop vaccines.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.
