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. 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.

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
Function and regulation of the Schlafen gene family: novel regulators of blood cell proliferation and function. The immediate outcomes of the proposed research will be in fundamental knowledge and understanding of important cellular and biological processes in which the Schlafen genes are involved. In particular, Schlafen genes are likely to play a role in inflammatory responses and in blood cell growth.

The immediate outcomes of the proposed research will be in fundamental knowledge and understanding of important cellular and biological processes in which the Schlafen genes are involved. In particular, Schlafen genes are likely to play a role in inflammatory responses and in blood cell growth. These process clearly have relevance to a range of major human (and animal) diseases including infectious disease, auto-immune disease and leukaemia, and thus a long-term outcome may be improved treatments for such disease.

Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity ....Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity, insulin resistance and various forms of cancers is well established) are leading to a rapid increase in new cancer cases, thus driving a rapid increase in demand for better treatments. This is particularly relevant in Indigenous health where obesity is on the rise following the transition from a traditional to an urban lifestyle.Read moreRead less

Summary
Cells of the immune system respond to invasion of the body by infectious or other damaging agents by switching on the production of a large array of proteins that are critical for an orchestrated immune response. Some of these proteins, referred to as cytokines, are secreted by the cells and act as intercellular messengers to affect the function of other cells need for an immune response. Switching on the production of these cytokines requires the genes that produce them to interpret the complex ....Cells of the immune system respond to invasion of the body by infectious or other damaging agents by switching on the production of a large array of proteins that are critical for an orchestrated immune response. Some of these proteins, referred to as cytokines, are secreted by the cells and act as intercellular messengers to affect the function of other cells need for an immune response. Switching on the production of these cytokines requires the genes that produce them to interpret the complex signaling pattern to which the cell has been exposed. These complex signaling patterns are interpreted in the nucleus by molecular switches that lie beside the genes in the DNA. The incorrect production of these proteins is involved in immune diseases such as autoimmunity, allergy and leukemia. Genes are housed in the nucleus of the cell, packaged into a structure known as chromatin. When the gene is not producing protein it is tightly packaged in chromatin but when it is activated to produce protein this packaging is altered to allow the gene to see the signals being received by the cell and produce protein. We have identified a protein within the nucleus that is critical in allowing certain cytokine genes to see the signals being received in the nucleus. By investigating the role of this protein (called c-Rel) in chromatin reorganization in immune cells, we hope to better define the steps required for appropriate gene activation in an immune response. This knowledge, in turn, will lead to the identification of novel therapeutic targets to control immune responsesRead moreRead less

Macrophages are a key component of the immune system; thier functions include killing of pathogens as well as cancerous cells. Macrophage lineage cells are derived from stem cells within the bone marrow and thier differentiation, proliferation and survival is mediated by a particular growth factor termed colony stimulating factor-1 (CSF-1). The understanding of how macrophage lineage cells develop will help us to treat many diseases including certain cancers (such as leukemia), arthritis and inf ....Macrophages are a key component of the immune system; thier functions include killing of pathogens as well as cancerous cells. Macrophage lineage cells are derived from stem cells within the bone marrow and thier differentiation, proliferation and survival is mediated by a particular growth factor termed colony stimulating factor-1 (CSF-1). The understanding of how macrophage lineage cells develop will help us to treat many diseases including certain cancers (such as leukemia), arthritis and inflammation, and disorders of the immune system. The action of CSF-1 is mediated by the CSF-1 receptor (CSF-1R) which, when activated, controls gene regulation. In this proposal we will study CSF-1R activation and identify the genes regulated by CSF-1 with a view to characterize genes critical for macrophage development. These genes may provide potential targets for new pharmacological agents.Read moreRead less

Summary
Switching on an immune response involves major changes in the gene expression program of the immune cells. These changes in gene expression take place in the context of DNA packaged into the nucleus in a structure known as chromatin. We will investigate the relationship between chromatin and gene expression changes and how this relationship plays a role in the timing of the immune response. This information will be useful in developing novel means of controlling aberrant immune responses.
