Neurotrophic factors for pelvic autonomic neurons: the role of neurturin. This project is about pelvic parasympathetic neurons, which are responsible for involuntary activities such as bladder voiding and penile erection. We are interested in the neurotrophic factors that determine survival of these neurons during early mammalian development and keep them healthy in adults. Little is known about ?parasympathetic neurotrophic factors? in general. However we have recently discovered that the prote ....Neurotrophic factors for pelvic autonomic neurons: the role of neurturin. This project is about pelvic parasympathetic neurons, which are responsible for involuntary activities such as bladder voiding and penile erection. We are interested in the neurotrophic factors that determine survival of these neurons during early mammalian development and keep them healthy in adults. Little is known about ?parasympathetic neurotrophic factors? in general. However we have recently discovered that the protein neurturin is very important in the pelvic parasympathetic system. We will determine exactly how neurturin affects pelvic neurons and how it interacts with other neurotrophic factors. Our results will fill a major gap in our knowledge of fundamental neurobiology.Read moreRead less
Differentiation of Cord Blood Stem cells into Thymus (T) cells with regulatory phenotype and function. This project will develop technologies for a stem cell therapy platform based on cord blood stem cells, to enable treatment of autoimmune diseases or transplants. Building on the University of Adelaide's frontier demonstration of differentiation of regulatory Thymus (T) cells from cord blood stem cells, the project will develop techniques to expand the numbers of T cells generated. This has the ....Differentiation of Cord Blood Stem cells into Thymus (T) cells with regulatory phenotype and function. This project will develop technologies for a stem cell therapy platform based on cord blood stem cells, to enable treatment of autoimmune diseases or transplants. Building on the University of Adelaide's frontier demonstration of differentiation of regulatory Thymus (T) cells from cord blood stem cells, the project will develop techniques to expand the numbers of T cells generated. This has the potential to maintain Australia's lead in differentiation of cord blood stem cells and to provide a significant breakthrough in potential treatments of autoimmune diseases (e.g. type 1 diabetes) or transplantation. These diseases affect both a healthy start to life and healthy ageing, and an Australian invention to treat or cure them would have global impact.Read moreRead less
Combined genetic and cellular analysis of melanisation to study variation in human pigmentation. This investigation examines variations in the genes that are important determinants of human skin pigmentation and are likely to be associated with skin cancer risk. Our research program will form the basis of future diagnostics based on major genes that determine a persons skin type. Current skin cancer prevention strategies rely predominantly on broad spectrum campaigns that are aimed at increasi ....Combined genetic and cellular analysis of melanisation to study variation in human pigmentation. This investigation examines variations in the genes that are important determinants of human skin pigmentation and are likely to be associated with skin cancer risk. Our research program will form the basis of future diagnostics based on major genes that determine a persons skin type. Current skin cancer prevention strategies rely predominantly on broad spectrum campaigns that are aimed at increasing the general community awareness of the damaging effects of UV radiation. A better understanding of the genetic basis of UV-sensitive skin types will greatly enhance the targeting of such skin cancer-prevention campaigns, provide an understanding of changes that occur in skin pathology, and the mechanisms of sun induced tanning.Read moreRead less

Summary
Cancer is a complex disease that involves the mis-regulation of genes and aberrant cell-cell communication . To help gain a better understanding of these processes it is possible to examine simpler systems. This proposal uses a unique cancer model in flies to understand how a change in cell fate can endow cells with the ability to continue dividing and invading surrounding tissues, thus driving cancer development.
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
Bacterial Proteomics: From Cell Division to Novel Antibiotic Targets. When a cell divides it is essential that each newborn cell gets a complete copy of the DNA. To ensure that this happens, cell division must be tightly controlled. It is not known how this occurs in bacteria. However, if we knew what molecules were involved in this control, we could target them to kill harmful bacteria. This project aims to identify such regulatory molecules as candidate targets for antimicrobial agents, with a ....Bacterial Proteomics: From Cell Division to Novel Antibiotic Targets. When a cell divides it is essential that each newborn cell gets a complete copy of the DNA. To ensure that this happens, cell division must be tightly controlled. It is not known how this occurs in bacteria. However, if we knew what molecules were involved in this control, we could target them to kill harmful bacteria. This project aims to identify such regulatory molecules as candidate targets for antimicrobial agents, with a view to developing powerful, novel antibiotics to protect us from the imminent threat of bioterrorism and antibiotic-resistant bacteria.

Proteomic analysis of subcellular changes during apoptosis. This project aims to use a novel proteomic approach to examine mechanisms of apoptosis at the level of the plasma membrane, mitochondrion, nucleus and cytosol, screening protein extracts of cell organelles by the new technique of SELDI-TOF mass spectrometry in which proteins are adsorbed onto activated chips. This will provide protein mass profiles characteristic of various stages of apoptosis, and will allow identification of proteins ....Proteomic analysis of subcellular changes during apoptosis. This project aims to use a novel proteomic approach to examine mechanisms of apoptosis at the level of the plasma membrane, mitochondrion, nucleus and cytosol, screening protein extracts of cell organelles by the new technique of SELDI-TOF mass spectrometry in which proteins are adsorbed onto activated chips. This will provide protein mass profiles characteristic of various stages of apoptosis, and will allow identification of proteins of interest by conventional proteomic methods. The establishment of SELDI-MS as a viable tool for cell proteomics would open new opportunities to understand a broad range of cellular functions at the level of protein expression.Read moreRead less
The effect of age on regulatory T cell control of the innate and adaptive antiviral immune responses. Viral pathogens are a lead cause of infant mortality in the world. This project will define how T regulatory cells limit protective antiviral immune responses in the young. This information is critical for the development of potent antiviral vaccines that are effective from the newborn period without inducing autoimmunity. It will also provide novel insight into the way T regulatory cells can b ....The effect of age on regulatory T cell control of the innate and adaptive antiviral immune responses.
