Our understanding of the in vivo dynamics of cellular immune responses to infectious diseases is poor. This project will utilise advanced intravital imaging combined with novel tools to dissect the cellular events involved in the generation and recall of T cell responses to localised virus infection, combined with a detailed functional analysis of the lymphoid organ stroma. Such fundamental information will contribute to the development of new generation vaccines and therapies to protect against tissue-specific infectious diseases, cancers and autoimmune diseases.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.

Imaging Cell and Tissue Architecture using Confocal and Super-Resolution Microscopy. Imaging cell and tissue architecture using confocal and super-resolution microscopy: This project aims to understand how the architecture of cells and tissues is controlled. This is because the organisation of biological space underpins the function of cells, tissues and organisms.

Imaging cell and tissue architecture using confocal and super-resolution microscopy: This project aims to understand how the architecture of cells and tissues is controlled. This is because the organisation of biological space underpins the function of cells, tissues and organisms. This project will test the role of identified parts of cell architecture in regulating specific animal functions/pathologies. It will do this by using new microscope technologies which are at the frontier of visualising cell structure in isolation and in the context of tissue including application to the living animal. The dynamic organisation of structures in cells will be imaged in living tissue. Novel insights into structure/function relationships in the body will impact the health industry and generate opportunities for new diagnostics and therapeutics. Read moreRead less
Cellular Organisation of Protective Immune Responses. Our immune system consists of a task force of white blood cells that coordinate to defeat invading pathogens. Research has revealed a cell receptor, CXCR3, controls immune cell interactions, which determine immune control and protection during initial cell activation and viral infection. This project will use a multi-disciplinary approach combining viral immunology, unique mouse models, advanced imaging, and bioinformatic analyses to dissect ....Cellular Organisation of Protective Immune Responses. Our immune system consists of a task force of white blood cells that coordinate to defeat invading pathogens. Research has revealed a cell receptor, CXCR3, controls immune cell interactions, which determine immune control and protection during initial cell activation and viral infection. This project will use a multi-disciplinary approach combining viral immunology, unique mouse models, advanced imaging, and bioinformatic analyses to dissect the cellular conversations that underpin immune protection. Revealing the mechanisms of cellular interactions during an immune response will have a major impact on development of targeted vaccines, and therapeutics (particularly for chronic infections and cancer), which are major health burdens.Read moreRead less

A novel link between metabolism and host defence. This project aims to delineate how a protein modification that consists of the addition of a small sugar to cellular proteins, known as O-GlcNAcylation, provides a link between metabolism and complex cell functions. The model for these studies is a cell type of the immune system known as dendritic cells. Upon encountering pathogens these cells undergo metabolic changes that increase the rate of O-GlcNAcylation of proteins involved in immune respo ....A novel link between metabolism and host defence. This project aims to delineate how a protein modification that consists of the addition of a small sugar to cellular proteins, known as O-GlcNAcylation, provides a link between metabolism and complex cell functions. The model for these studies is a cell type of the immune system known as dendritic cells. Upon encountering pathogens these cells undergo metabolic changes that increase the rate of O-GlcNAcylation of proteins involved in immune responses, altering their function. This project will study how O-GlcNAcylation works and is regulated. The project expects to develop new technology and provide high-level training, increasing the competitiveness of the strategic biotechnology sector in AustraliaRead moreRead less
Multifunctional biodegradable nanoparticles for enhanced DNA vaccine delivery. DNA vaccine, which shows better immunological and economic merits than conventional vaccines, suffers clinical failure due to the difficulty of delivering intact DNA molecules to relevant cells. This project seeks to develop smart polymer nanospheres to protect the DNA molecules from premature degradation in order to improve its efficacy.

Summary
Immune cells mature into distinct populations with specialized functions. One subsets are T follicular helper (TFH) cells which are important for instructing B cells to produce antibodies following infection or vaccination. The means by which TFH cells are generated are unknown. We will determine mechanisms whereby TFH cells are produced and how they function. We hope to design approaches that will modulate the function of TFH cells in cases of immunodeficiencies, autoimmunity or vaccination.
A study into post-translational modifications on adaptive immunity. Using proteomics, structural biology and cellular immunology, this project aims to provide a greater understanding of the impact of PTMs on the immune system. The immune system combats pathogens by mounting T-cell responses against foreign antigens present in infected cells. However, T-cells activated by self-antigens that are inadvertently presented by healthy cells can cause aberrant T-cell reactivity and disease.

Using proteomics, structural biology and cellular immunology, this project aims to provide a greater understanding of the impact of PTMs on the immune system. The immune system combats pathogens by mounting T-cell responses against foreign antigens present in infected cells. However, T-cells activated by self-antigens that are inadvertently presented by healthy cells can cause aberrant T-cell reactivity and disease. Post-translational modifications (PTMs) are common in the host's proteins, but surprisingly little is known about their effect on T-cell immunity.Read moreRead less
