Elucidating the regulation of cell death by random mutagenesis of key apoptotic proteins. All organisms need to remove damaged or excessive cells. This cell death process is called apoptosis. Defects in apoptosis result in numerous diseases including cancer, and neurodegenerative and immune disorders.

All organisms need to remove damaged or excessive cells. This cell death process is called apoptosis. Defects in apoptosis result in numerous diseases including cancer, and neurodegenerative and immune disorders. Determining how this process is regulated is of crucial importance for therapeutic intervention. We will utilise a powerful strategy to mutate proteins required for apoptosis so that they no longer work, which will allow the identification of protein regions essential for cell death activity . This will lead to identification of potential drug targets to control apoptosis. Elucidating the mechanism of cell death will lead to the development of novel and improved therapies for diseases such as cancer and neurodegenerative disease.Read moreRead less
Role of the PU.1 transcription factor in regulating lymphoid development. Haemopoiesis is a tightly regulated process and provides an important model for our understanding and application of stem cell biology. Perturbation of early haemopoiesis results in a number of important disorders including leukaemia, anaemia and immunodeficiency. The application of stem cells to many disease conditions is currently being pursued, however, in order to develop therapeutic interventions knowledge of normal c ....Role of the PU.1 transcription factor in regulating lymphoid development. Haemopoiesis is a tightly regulated process and provides an important model for our understanding and application of stem cell biology. Perturbation of early haemopoiesis results in a number of important disorders including leukaemia, anaemia and immunodeficiency. The application of stem cells to many disease conditions is currently being pursued, however, in order to develop therapeutic interventions knowledge of normal cellular differentiation is crucial. The studies outlined here aim to contribute to the understanding of the these processes and hence help to provide the framework for future studies aimed at more directly altering cell fate decision for clinical applications.

Summary
A microarray platform for gene expression analysis and genotyping in biological systems. This technology has substantial benefits for basic science and biotechnology. The ability to rapidly study changes in gene expression in living organisms will benefit agriculture, animal and biomedical science and biotechnology. The Affymetrix platform creates opportunities for new avenues of research, such as studying epigenetic (DNA and protein modifications) mechanisms in development, ageing and disease. ....A microarray platform for gene expression analysis and genotyping in biological systems.

Summary
Multiphoton microscopy of living animals as a tool for immunology and cell biology studies. The multiphoton microscope will enable us to watch the growth, migration and interactions of cells in a living animal in response to changes in the cells' environment will give us better understanding of how we work as living machines, and what can go wrong with that process to make us unwell.
Brain metabolic changes in experimental malaria: a paradigm for the molecular mechanisms of intravascular inflammation. Malaria is endemic in countries directly to the north of Australia, as close as Papua New Guinea and East Timor. This project's findings about malaria also will have relevance to other infectious diseases of national importance. The outcomes will contribute to Australia's research reputation. We will build international links that will increase the national knowledge base and r ....Brain metabolic changes in experimental malaria: a paradigm for the molecular mechanisms of intravascular inflammation. Malaria is endemic in countries directly to the north of Australia, as close as Papua New Guinea and East Timor. This project's findings about malaria also will have relevance to other infectious diseases of national importance. The outcomes will contribute to Australia's research reputation. We will build international links that will increase the national knowledge base and research skill base. Young scientists will be trained in state-of-the-art research techniques in a cross-disciplinary environment that is the way of future biological research. The project may identify potential drug targets for malaria or other infectious diseases. The Intellectual Property will be protected and commercialised.Read moreRead less
Microparticles as effectors of microvascular alterations in brain inflammation. Cerebral malaria (CM) kills many children worldwide, but we do not understand why their small blood vessels in the brain become obstructed. We found that tiny elements detached from cell membranes, called microparticles (MP), are dramatically elevated in the blood during CM. Our results strongly suggest that these MP are important in CM development. We have found that some drugs block the release of MP and the stick ....Microparticles as effectors of microvascular alterations in brain inflammation. Cerebral malaria (CM) kills many children worldwide, but we do not understand why their small blood vessels in the brain become obstructed. We found that tiny elements detached from cell membranes, called microparticles (MP), are dramatically elevated in the blood during CM. Our results strongly suggest that these MP are important in CM development. We have found that some drugs block the release of MP and the stickiness of malaria parasites to blood vessels. Our project will tackle the conditions of MP production and define new drugs to prevent it. It also will explain how the brain becomes affected by high numbers of MP. Our results will cast new light on why the brain functions abnormally when its blood vessels become modified.Read moreRead less

Unbalanced immune responses may cause or worsen common and important diseases such as infections, allergies, cancers and autoimmunity. Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response. Fowlpox viruses (FPV) provide safe and effective human vaccines.

Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response. Fowlpox viruses (FPV) provide safe and effective human vaccines. Engineering FPV to make both a relevant antigen and a cytokine is proprietary technology. With our commercial partner and using experimental mice, we will test the concept that FPV making a model antigen and IL-4 initiate and/or maintain beneficial Type 2 responses. A successful outcome will guide clinical FPV-based vaccine development for the treatment of important human and veterinary diseases.Read moreRead less

Transcriptional and epigenetic regulation of terminal lymphocyte differentiation and alterations of the same that lead to leukemia. In the developed world infection diseases are the number three killer behind heart disease and cancer, and huge financial effort is put into treatment and prevention.

In the developed world infection diseases are the number three killer behind heart disease and cancer, and huge financial effort is put into treatment and prevention. Despite this, results have often been disappointing. One cause of these poor outcomes is the lack of knowledge of how effective immune responses are generated. This project aims to better understand the processes that control the generation of protective lymphocytes. It will deliver information that may enable a more targeted approach to vaccine-development and treatments of infections. As defective differentiation can also be a cause of leukemia it may also lead to targets of cancer treatment.Read moreRead less
