Regulation of Stress Hormone Receptors in the Brain. Our research will provide information on how the brain controls our response to stress and will allow the development of targeted strategies to reduce the possibility during chronic stress of the development of conditions such as anxiety and depression. This will improve mental health outcomes in Australia and add to Australia's economic and social stability.

Alzheimer's disease (AD) is the most common form of dementia in the ageing population. This research project aims to identify and characterise new genes involved in the copper regulation of the Alzheimer's disease gene. This may lead to the development of novel therapeutic targets and clinical intervention strategies as well as early diagnostic procedures in preventative healthcare for the treatment of AD. The benefits would affect the international community as a whole, potentially minimising the socio-economic costs arising from the predicted world-wide increase in AD in the ageing population.Read moreRead less
Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will im ....Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will improve our mechanistic understanding of genetic diseases in populations. In addition, this proposal is expected to lead to identification of potential targets and technologies that would be of interest to Australian industry.Read moreRead less
Calcium signalling in neurons of the central nervous system. Understanding of the processes of cell-to-cell communication between neurons that comprise the brain and central nervous system is of primary importance to our understanding of fundamental phenomena such as voluntary and reflex movement, sensory responses and learning and memory.

Understanding of the processes of cell-to-cell communication between neurons that comprise the brain and central nervous system is of primary importance to our understanding of fundamental phenomena such as voluntary and reflex movement, sensory responses and learning and memory. We would like to obtain a better understanding of how calcium controls neuronal and synaptic function. These studies will combine high-speed fluorescence imaging, electrophysiological recording, gene transfer using Adeno- and Sindbis viruses, and genetically designed and targeted biosensors to describe key "descriptors" of the calcium signals generated as neurons of the central nervous system ?talk? to each other.Read moreRead less

This will both support and further enhance a core group of high quality researchers to engage in cutting-edge research in areas of acknowledged expertise as well as priority within their respective institutions. In addition, it will facilitate wide-ranging collaborative arrangements to further develop and exploit this research area.Read moreRead less
Molecular neurobiology of the GABAB receptor: Studies of heteromeric receptor function and signalling. The G protein-coupled receptor (GPCR) for the inhibitory transmitter gamma- aminobutyric acid (GABA) is a unique heterodimer. Molecular analyses will be undertaken to provide insights into its signalling mechanisms and functional regulation.

The G protein-coupled receptor (GPCR) for the inhibitory transmitter gamma- aminobutyric acid (GABA) is a unique heterodimer. Molecular analyses will be undertaken to provide insights into its signalling mechanisms and functional regulation. Investigations employing point mutant and chimeric receptors will analyse how ligand binding to the extracellular domain of the GABA-BR1 subunit triggers G protein-coupling to the intracellular portion of the GABA-BR2 subunit. Focus will be on different modes of GPCR signalling, including constitutive activity and roles for membrane and cytosolic regulatory proteins. Targeted studies of GABAB receptor subunits will provide new information on the mechanistic regulation of GPCR signalling.Read moreRead less

This project will strengthen Australia's research capabilities in the areas of molecular neurobiology and neurogenetics. The project will equip students with the intellectual and technical skills needed to work in priority areas such as genomics and biotechnology, as well as in medical and agricultural research, and education. The research has possible long term applications in modifying the behaviour of insects of agricultural or medical importance. For example, by inhibiting the ability of insects to perceive specific odours it may ultimately be possible to prevent insects that carry disease from identifying target animals, or plant pests from locating their host plants.Read moreRead less
Olfactory signalling and coding in Drosophila and other insects. Animals rely on olfactory cues to detect food, danger, and others of the same species. The olfactory systems of Drosophila and other insects are simpler than those of mammals, yet complex enough to offer fascinating systems for studying neural information processing.

The olfactory systems of Drosophila and other insects are simpler than those of mammals, yet complex enough to offer fascinating systems for studying neural information processing. This project aims to investigate the role of the Drosophila odorant receptors in olfactory coding, and to use multiple approaches to isolate components of the poorly understood insect olfactory signal transduction pathway. In addition, the role of the NO/cGMP pathway in olfactory signalling will be studied using an olfactory mutant that has nitric oxide synthase defects.Read moreRead less

Functional studies on a novel, brain-specific, Golgi ATP-binding protein in membrane trafficking. In cells specialised for communication such as neurones, protein transport constitutes a large part of total cellular activity. A primary pathway in protein transport is trafficking from the Golgi apparatus to the cell membrane; materials destined for the cell membrane and secretion are sorted, packed and transported from the Golgi apparatus. However, the mechanisms underlying these processes at the ....Functional studies on a novel, brain-specific, Golgi ATP-binding protein in membrane trafficking. In cells specialised for communication such as neurones, protein transport constitutes a large part of total cellular activity. A primary pathway in protein transport is trafficking from the Golgi apparatus to the cell membrane; materials destined for the cell membrane and secretion are sorted, packed and transported from the Golgi apparatus. However, the mechanisms underlying these processes at the Golgi remain largely unknown. We have recently cloned a novel ATP-binding protein specifically expressed at the Golgi apparatus in human brain, and hypothesise that this protein regulates Golgi protein trafficking by interacting with two other molecules, dynamin and calcium, during cell secretion.Read moreRead less
