This project aims to delineate the cellular interactions involved in the initiation of immune responses by utilising advanced in vivo imaging. Adaptive immunity in vertebrates functions via the acquisition of signals by immune cells via complex interactions with other immune cells, yet these exchanges are difficult to observe and define. This project expects to provide insights into the mechanisms that underpin effective cell-mediated immune responses. The expected outcomes are to generate fundamental new knowledge about immune responses and enhance capacity to study the immune system. This could benefit future development of new vaccines and therapies to improve health.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

Summary
Decoding the enigmatic biology of human gamma-delta T cells. The immune system surveys our body examining molecules that signal whether or not everything is ok. T cells are a central to this and use their receptors to monitor these molecular signals. A specialised subset of T cells known as gamma-delta T cells are critical to detecting infection and cancer, yet their fundamental biology is poorly understood. This project aims to unravel this elusive biology. The aims are to understand 1. The div ....Decoding the enigmatic biology of human gamma-delta T cells. The immune system surveys our body examining molecules that signal whether or not everything is ok. T cells are a central to this and use their receptors to monitor these molecular signals. A specialised subset of T cells known as gamma-delta T cells are critical to detecting infection and cancer, yet their fundamental biology is poorly understood. This project aims to unravel this elusive biology. The aims are to understand 1. The diversity in function between gamma-delta T cell subsets, and 2. The diversity in gamma-delta T cell receptors and the molecules that these receptors detect. This work is essential for understanding gamma-delta T cell immunology which is critical if we ultimately wish to harness this to improve human health.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
Unraveling the chromatin networks that control T lymphocyte differentiation. The development of T cell responses is essential for fighting infection but in some cases T cells can also cause allergy and autoimmune diseases. Previous research has shown by understanding the complex chromatin circuitry that underlie T cell function, therapies can be designed to rewire harmful T cells. This project will use a multi-disciplinary approach that combines expertise in cutting-edge molecular techniques wit ....Unraveling the chromatin networks that control T lymphocyte differentiation. The development of T cell responses is essential for fighting infection but in some cases T cells can also cause allergy and autoimmune diseases. Previous research has shown by understanding the complex chromatin circuitry that underlie T cell function, therapies can be designed to rewire harmful T cells. This project will use a multi-disciplinary approach that combines expertise in cutting-edge molecular techniques with unique mouse models and bioinformatics to develop a fundamental understanding of the chromatin architecture and epigenetic networks that control important steps of T cell differentiation during development, allergy and infection.Read moreRead less
Epigenetic regulation of immune memory. Immune memory cells emerge from the dynamic and transient immune response to deliver two critical abilities: to produce rapid recall responses upon reinfection but also to persist for decades. This project aims to define how the polycomb repressive complexes regulate immune cell fate, by utilising cutting-edge cell and chromatin biology techniques coupled with bioinformatic pipelines. Expected outcomes of the proposed research include key insights into epi ....Epigenetic regulation of immune memory. Immune memory cells emerge from the dynamic and transient immune response to deliver two critical abilities: to produce rapid recall responses upon reinfection but also to persist for decades. This project aims to define how the polycomb repressive complexes regulate immune cell fate, by utilising cutting-edge cell and chromatin biology techniques coupled with bioinformatic pipelines. Expected outcomes of the proposed research include key insights into epigenetic programming required for immune cell differentiation and longevity. This should provide significant benefits such as knowledge creation that may lead to development of technology that reprograms cell behaviour, and contribution to Australian research recognition and capacity.Read moreRead less
