SNARE-mediated perforin and cytokine release in natural killer cells. Cytotoxic cells release toxic granules and cytokine messengers to kill pathogen infected and cancerous cells and to mount immune responses. This project will investigate different SNARE molecules that regulate the secretion of perforin from granules and cytokines from other carriers, assisting in the understanding of complex but essential cellular pathways.
Imaging the generation and recall of protective antiviral immune responses in vivo. 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 contr ....Imaging the generation and recall of protective antiviral immune responses in vivo. 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
Defining the immunological roles of stromal cells within lymphoid tissues. The populations of endothelial and mesenchymal cells that construct the lymphoid tissues are being revealed as key players in the priming and orchestration of immune responses. Yet, fundamental knowledge of the molecular makeup and the functions of these stromal cells, particularly their roles in immune responses, is sorely lacking. This project will utilise a multidisciplinary approach including advanced imaging and bioi ....Defining the immunological roles of stromal cells within lymphoid tissues. The populations of endothelial and mesenchymal cells that construct the lymphoid tissues are being revealed as key players in the priming and orchestration of immune responses. Yet, fundamental knowledge of the molecular makeup and the functions of these stromal cells, particularly their roles in immune responses, is sorely lacking. This project will utilise a multidisciplinary approach including advanced imaging and bioinformatics to dissect the functions of the lymphoid stromal cells and their roles in the swelling of lymphoid tissues during immune responses. This will provide vital information about the biology of these understudied cells and reveal the ways in which they support the generation of immunity.Read moreRead less
Structural and functional analysis of the protein kinase R. We have shown that protein kinase R (PKR) plays a key role in regulating the body's response to virus infections, inflammation and cancer. This project will identify mechanisms that regulate the activity of PKR and provide information useful for the development of novel drugs.
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 project aims to establish a high throughput protein nanocrystallisation and imaging facility for protein crystallography. Protein crystallography is an important field of biological research, however there are many proteins, such as integral membrane proteins and transient molecular complexes that are more challenging to crystallise. The facility aims to use state-of-the-art imaging and crystallisation techniques, including second order nonlinear imaging of chiral crystals (SONICC) imaging and lipid cubic phase approaches, to enable structural studies to be undertaken on challenging proteins. This information is often used for the rational development of therapeutics. The facility would support cutting-edge biological research In Australia.Read moreRead less

Summary
Comprehensive cell imaging facility. This facility will provide Australian biological science researchers with equipment for in-depth analyses of cell function in vitro and in vivo. It will enable innovative research targeted at important questions in fields including cancer, immunology, stem cell biology, infectious disease and tissue regeneration.
Investigating the molecular basis of T-cell receptor cross-reactivity. This project will explore the basis of unexpected immune reactions whereby the immune system mistakes one molecular structure for another, a phenomenon known as cross-reactivity. This project will examine how often this is due to molecular mimicry, potentially explaining why immune T cells sometimes react inappropriately to different agents.
Expression and substrate recognition by MARCH ubiquitin ligases. Eukaryotic cells are compartmentalised, with different organelles playing distinct functions. This project will characterise the MARCHs, proteins which control the localisation and half-life of other proteins. Understanding how the MARCHs work will provide novel insights into fundamental cellular processes that play major roles in many biological functions.
