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
Molecular determinants of an allergic response. Some humans develop allergies after exposure to environmental allergens while others do not. At present, the reason for this individual variation is not known. By comparing the processes activated in allergic versus non-allergic individuals, this study will identify critical molecules involved in making individuals susceptible to allergies, which will be used to develop safer and more effective allergy vaccines.
How the immune system recognises vitamin B-based allergies. This project aims to evaluate the range of molecules that can stimulate vitamin B-reactive T cells in mammals and amphibians, and the degree of conservation or variation in these molecules among diverse microorganisms. T cells are immune cells that recognise foreign molecules, including peptides, lipids and vitamin B metabolites, bound to specialised antigen-presenting molecules. In mammals, Mucosal Associated Invariant T cells, still p ....How the immune system recognises vitamin B-based allergies. This project aims to evaluate the range of molecules that can stimulate vitamin B-reactive T cells in mammals and amphibians, and the degree of conservation or variation in these molecules among diverse microorganisms. T cells are immune cells that recognise foreign molecules, including peptides, lipids and vitamin B metabolites, bound to specialised antigen-presenting molecules. In mammals, Mucosal Associated Invariant T cells, still poorly understood, recognise Vitamin B-based molecules. Combining immunology with structural biology and chemistry, this project aims to understand how the immune system detects molecules produced by diverse microorganisms.Read moreRead less
Dissecting the Parameters for the Generation of Cytotoxic T Lymphocyte Immunity. This project aims to identify mechanisms by which antigen-presenting cells, such as dendritic cells, prime CD8+ T cells to generate effector and memory populations at the molecular level. The specific intention is to identify reagents capable of licensing dendritic cells, and examine the down-stream gene products/pathways generated by these signals using microarray analyses. Such knowledge will provide new insight i ....Dissecting the Parameters for the Generation of Cytotoxic T Lymphocyte Immunity. This project aims to identify mechanisms by which antigen-presenting cells, such as dendritic cells, prime CD8+ T cells to generate effector and memory populations at the molecular level. The specific intention is to identify reagents capable of licensing dendritic cells, and examine the down-stream gene products/pathways generated by these signals using microarray analyses. Such knowledge will provide new insight into CTL generation by providing greater understanding of how multicellular systems function both at the cellular and molecular level.Read moreRead less

This proposal represents an excellent opportunity for Australian science to participate in state-of-the-art research into the immune system and to be internationally competitive with the best researchers in the field. By combining advanced microscopy techniques with well developed biological models used by researchers at the University of Melbourne, this project will greatly improve our understanding of the dynamic interactions that occur between cells of the immune system during infectious diseases. The insight provided by this project will facilitate the design of better vaccines for protection against diseases, including influenza.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

Summary
Biology of immune cells. This project aims to study immune cells that target harmful microbes by recognising by-products of their metabolism, and develop methods modulating their function. In particular, it aims to determine the immune recognition of the full range of microbial metabolites that activate these cells and unravel the mechanisms behind tolerance to nutrition-derived metabolites. This project is a potential opportunity for Australia to maximise its competitive edge in this field and ....Biology of immune cells.

In particular, it aims to determine the immune recognition of the full range of microbial metabolites that activate these cells and unravel the mechanisms behind tolerance to nutrition-derived metabolites. This project is a potential opportunity for Australia to maximise its competitive edge in this field and develop immune-modulatory agents ultimately leading to socioeconomic benefit.Read moreRead less
Unrestricted antigen recognition by T lymphocytes. This project aims to investigate the unrestricted T cell repertoire; the molecular and structural basis of antigen recognition by unrestricted T cells; and the development of unrestricted T cells. T lymphocytes typically are restricted to detecting foreign molecules (antigens) on the cell membrane in association with specialised antigen-presenting molecules encoded within the highly polymorphic major histocompatibility (MHC) locus (MHC restricti ....Unrestricted antigen recognition by T lymphocytes. This project aims to investigate the unrestricted T cell repertoire; the molecular and structural basis of antigen recognition by unrestricted T cells; and the development of unrestricted T cells. T lymphocytes typically are restricted to detecting foreign molecules (antigens) on the cell membrane in association with specialised antigen-presenting molecules encoded within the highly polymorphic major histocompatibility (MHC) locus (MHC restriction). T lymphocytes that can recognise antigens in the absence of MHC or MHC like molecules challenges a major paradigm in the field of immunology. As T cell based therapy underpins treatments for cancer and infection, new mechanisms of T cell activation that are independent of patient genotype should ultimately create opportunities for therapeutic and commercial development, leading to both health and economic benefits.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.

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 way we think about the clonal selection of lymphocytes, the fundamental theory underlying our understanding of the immune system.Read moreRead less
