Summary
Novel postsynaptic functions of the microtubule-associated protein tau. The protein tau is present in abnormal deposits in brains of individuals with dementia. The main aim of this project is to unravel and understand in detail new roles of tau in neurons and thus shed new light into normal brain function. Understanding these new functions of tau will aid in identifying new ways to treat these debilitating diseases.
Cellular mechanisms that protect against copper-bound beta-amyloid. This project will investigate some of the brain’s own mechanisms for protecting itself against Alzheimer’s disease. Understanding these mechanisms will be important for developing future therapeutic strategies for treating Alzheimer’s disease.

The equipment requested will facilitate the work of the Australian Mouse Brain Mapping Consortium, a consortium of Australian research groups collaborating to provide the only mouse model brain mapping capability in the country. The consortium brings together laboratory, neuroimaging and computational expertise in a comprehensive framework for imaging the mouse brain. This will help researchers to study mouse models of genetic and acquired disorders across the life-span. Remote viewing and analysis capabilities will help overcome the 'tyranny of distance', increasing national access to the facility. Repositories of digitised images will increase the availability of valuable research material to other Australian and international researchers.Read moreRead less
Cellular and Neurochemical Basis of Drug Addiction. Addiction to the major drugs of abuse, including heroin, amphetamines, cocaine, nicotine and alcohol damage the lives and cause premature death of more than 20% of Australians. Addiction produces long-term disruption of brain processes that lead to loss of control over urges to consume drugs and persistent cycles of relapse to drug taking. This research will apply new neurochemical approaches to discover mechanisms of disrupted brain function t ....Cellular and Neurochemical Basis of Drug Addiction. Addiction to the major drugs of abuse, including heroin, amphetamines, cocaine, nicotine and alcohol damage the lives and cause premature death of more than 20% of Australians. Addiction produces long-term disruption of brain processes that lead to loss of control over urges to consume drugs and persistent cycles of relapse to drug taking. This research will apply new neurochemical approaches to discover mechanisms of disrupted brain function that occur during development of addiction and relapse that are critical for development of better strategies to treat the disorder.

Summary
The role of the unfolded protein response in tau neurobiology and pathology. The main role of the protein tau is the stabilisation of the scaffolding of cells. In a group of dementias, tau forms abnormal clumps within the cells of the brain causing them to die. This project will investigate the cellular processes involved in normally preventing tau proteins from clumping and their role in the development of the abnormal tau clumps.

The neural bases of decision-making. This research focuses on the neural bases of decision making, a general capacity affected by normal ageing, disorders associated with neurodegeneration including dementia, major psychiatric conditions and drug addiction. Changes in the neural systems that result in the cognitive and emotional dissociation reflected in these disorders constitute the highest health, economic and social capital attrition burden to Australia of any disease group, a burden that is ....The neural bases of decision-making. This research focuses on the neural bases of decision making, a general capacity affected by normal ageing, disorders associated with neurodegeneration including dementia, major psychiatric conditions and drug addiction. Changes in the neural systems that result in the cognitive and emotional dissociation reflected in these disorders constitute the highest health, economic and social capital attrition burden to Australia of any disease group, a burden that is only predicted to increase as the population ages. Understanding these changes in neural systems and their specific behavioural effects is, therefore, of critical importance and will ultimately provide new targets for treatment and rehabilitation.Read moreRead less
The role of tropomyosin in coordinated neurite branching. This project will explore how nerve cells generate a highly branched network of cell processes which allows all higher functions of the nervous system. We previously discovered the central role of a component of the cell architecture in determining the branching pattern and in this project expect to reveal the molecular basis for its function.
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
The role of LIM Kinase 1 in neurons. The aim of this project is to study LIM domain kinase 1 in neuronal function, using cell and mouse models. Unrestricted brain function is essential to one’s wellbeing and the ability to perform normally. Critically contributing to the function of neurons is a cytoskeleton which maintains morphology and function. However, molecular mechanisms underlying cytoskeletal dynamics are poorly understood. LIM domain kinase 1, a key regulator of the actin cytoskeleton ....The role of LIM Kinase 1 in neurons.

Critically contributing to the function of neurons is a cytoskeleton which maintains morphology and function. However, molecular mechanisms underlying cytoskeletal dynamics are poorly understood. LIM domain kinase 1, a key regulator of the actin cytoskeleton decreased with age and its loss associated with deficits in memory and neuronal morphology. This project could reveal fundamental processes regulating and maintaining brain function.Read moreRead less
Unraveling the role of N-acetyl-aspartate in normal brain function and disease. The purpose of this project is to define the role of the predominating brain chemical N-acetyl-aspartate for normal nerve cell function and as toxic agent causing neurological illness and severe mental health problems. Findings of this research will enhance the design of novel therapies involving pharmacological and genetic treatment.
