This Project aims to investigate the role of structural and functional cellular components known as microtubules in nervous system regeneration. This Project aims to use innovative approaches in confocal and electron microscopy, genetics, and cell biology, with the expectation of generating new knowledge into nervous system repair. Expected outcomes of this Project include a comprehensive description of how microtubules are rearranged following nervous system injury and the importance of microtubule modifying proteins in promoting regeneration. This should provide significant benefits in our understanding of the cellular mechanisms behind nervous system repair, and offer new approaches for promoting regeneration after injury.Read moreRead less
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
Cellular And Molecular Characterization Of Erythroid Enucleation

Funding Amount
$671,950.00
Summary
A major challenge for transfusion medicine is the constant difficulties in obtaining enough supply of specific red blood cell (RBC) subtypes. In this proposal, we will identify the key steps of enucleation (extrusion of nucleus), a rate limiting process for the in vitro production of RBCs. A better understanding of this process will lead to improved strategies for the efficient and rapid production of self-generated RBCs for individual patient transfusion.
Understanding The Ancestry Of De Novo Blood Formation In The Early Embryo

Summary
Current laboratory methods rely on a hit-or-miss approach for the production of such cells, making the prospect of producing patient-specific cells an inefficient/financially prohibitive process. This project aims to generate new knowledge into when and how fate of early blood cells in selected in nature. With this information we will be able to devise effective blood progenitor cell production strategies in the laboratory.
Developing A New Treatment Method To Prevent Lymphopenia Associated With Sepsis

Summary
Sepsis or blood poisoning kills more people than breast cancer, prostate cancer and HIV/AIDS combined. It has a huge economic burden, yet there is no proper diagnostics markers or treatment. One of the main reasons for sepsis-mediated mortality is lack of functioning immune system patients. We have been able to elucidate the molecular mechanism of sepsis-mediated immune cell death and through this project, we aim to develop diagnostics and therapy for treating sepsis-mediated immune suppression.
Understanding the diverse biology of CD4+ T cell resident memory. This project aims to examine the biology of CD4 T cell memory in tissues. The previously unappreciated complexity of the CD4 T cell resident memory compartment in the liver will be characterised, focusing on the generation, maintenance and diversity of functions of these cells. Expected outcomes include the generation of fundamental knowledge in the disciplines of cellular biology and immunology, and unique, highly specialised stu ....Understanding the diverse biology of CD4+ T cell resident memory. This project aims to examine the biology of CD4 T cell memory in tissues. The previously unappreciated complexity of the CD4 T cell resident memory compartment in the liver will be characterised, focusing on the generation, maintenance and diversity of functions of these cells. Expected outcomes include the generation of fundamental knowledge in the disciplines of cellular biology and immunology, and unique, highly specialised student and personnel training through the interdisciplinary approach utilised, which spans cellular biology, live-imaging and transcriptomic analyses. Expected benefits include influential publications and the import of a novel, specialised technique to Australia through an international collaboration (Germany)Read moreRead less
A cellular hub for the organisation of T cell priming. 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 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

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
Dual Targeting Of Myc And Apoptosis Pathways For Improved Blood Cancer Treatment Outcomes

Summary
Cancer cells frequently possess defects in genes called MYC and BCL-2 that control their growth and survival. Our preliminary studies have shown that combining novel reagents that specifically target MYC plus BCL-2 leads to enhanced lymphoma cell killing. In the proposed research, we will further develop these reagents and evaluate their ability to treat blood cancer in mice. We expect our approach will provide new avenues for treating cancer patients that respond poorly to current treatments.
