In national terms, it will contribute to the concerted effort by Australian scientists to understand how and why neurons die following brain injury or neurodegenerative disease. Furthermore, this research contributes directly to the Designated National Research Priorities by identifying some of the earliest biochemical and cellular processes associated with aging or disease of the brain.Read moreRead less
Role of the complement system in the healthy and diseased central nervous system. The investigation into the role of the immune system in the central nervous system will increase our understanding of the causes behind the neurodegenerative process in aging individuals. This research will also indicate the potential for new types of anti-inflammatory drugs, to be used to slow the neurodegenerative process occurring naturally in the aging brain. These drugs could also be useful in treating drastic ....Role of the complement system in the healthy and diseased central nervous system. The investigation into the role of the immune system in the central nervous system will increase our understanding of the causes behind the neurodegenerative process in aging individuals. This research will also indicate the potential for new types of anti-inflammatory drugs, to be used to slow the neurodegenerative process occurring naturally in the aging brain. These drugs could also be useful in treating drastic neurodegenerative diseases such as motor neuron disease, Huntington's disease and Parkinson's disease. Of these, only Parkinson's disease currently has some effective treatments. Community and National benefits would be increased health, decreased stress and major economic savings.Read moreRead less
Targeting brain lipid homeostasis to treat Alzheimer's disease. Dementia affects approximately 250,000 people in Australia at an estimated cost (in 2002) of $6.6 billion per annum. The major cause of dementia (accounting for approximately 70% of all cases) is Alzheimer's disease (AD); a progressive neurodegenerative illness for which there is no curative or disease-stalling treatment. Due to increases in life expectancy, the incidence of AD is predicted to triple by 2050 unless disease-modifying ....Targeting brain lipid homeostasis to treat Alzheimer's disease. Dementia affects approximately 250,000 people in Australia at an estimated cost (in 2002) of $6.6 billion per annum. The major cause of dementia (accounting for approximately 70% of all cases) is Alzheimer's disease (AD); a progressive neurodegenerative illness for which there is no curative or disease-stalling treatment. Due to increases in life expectancy, the incidence of AD is predicted to triple by 2050 unless disease-modifying treatments are developed. This research program will provide novel realistic pharmaceutical approaches to treat AD. Even if the onset of AD could be delayed by a few years the personal and financial benefits would be enormous. The potential for this research to generate commercially viable Australian intellectual property is also significant.Read moreRead less
Novel cellular functions of the microtubule-associated protein tau: Physiological and pathological implications. The social and economic burden of Alzheimer's disease (AD) is enormous, and by 2040 more than 500,000 Australians will suffer from this disease. A key histopathological hallmark of this and many other related diseases are insoluble deposits of the protein tau.

The social and economic burden of Alzheimer's disease (AD) is enormous, and by 2040 more than 500,000 Australians will suffer from this disease. A key histopathological hallmark of this and many other related diseases are insoluble deposits of the protein tau. Research into novel functions of tau in signalling and transport (both of which are heavily compromised in diseased brains) will be followed directly by assay development for tau-directed drug screening. The national benefit of this research is manifold by (a) patenting new data, (b) developing treatment strategies for an un-curable disease, and (c) establishing links to the growing Australian biotech industry (in addition to existing links to international pharmaceutical companies).Read moreRead less

The project uses a combination of transgenic mouse strains characterised by neurodegeneration and senescence-accelerated (SAM) mice, to determine the first steps of the aggregation of the protein tau in degenerating neurons, how absence of tau protects from brain atrophy, and in which physiological processes tau is involved. This project provides the biological foundation for a tau-based therapy of senescence-associated conditions. It provides the biological foundation for developing effective therapies for human neurodegenerative conditions, by preventing tau aggregation and phosphorylation. We will patent new data and expand our existing links to Australian biotech and international pharmaceutical companies.Read moreRead less

Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, an ....Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, and what target molecules they act on. A better understanding of these factors will increase the chances of finding cures and developing better treatments for important inflammatory diseases of the ageing population.Read moreRead less
The role of preferred brain states in perceptual and cognitive processing: New insights into brain dynamics. New insights into brain dynamics will improve our understanding of both normal and atypical functioning. Extending previous work on normals will confirm how innovative Australian approaches can lead the research agenda in basic neuroscience, at the psychology-physiology interface.

New insights into brain dynamics will improve our understanding of both normal and atypical functioning. Extending previous work on normals will confirm how innovative Australian approaches can lead the research agenda in basic neuroscience, at the psychology-physiology interface. Testing in AD/HD and elderly populations will clarify dysfunctional brain mechanisms underlying AD/HD, and the cognitive losses in elderly populations (exacerbated by dementia). These results may lead to better diagnosis, treatment, and community understanding of these groups. Also, publications on these target groups will demonstrate internationally the widespread utility of this approach, encouraging further novel applications of basic neuroscience in health.Read moreRead less
