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

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. 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 u ....Olfactory signalling and coding in Drosophila and other insects.

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
Characterisation of a novel neural-specific ATPase in cholesterol transport. Ageing is determined by both genetic and metabolic factors. To a large part, the detailed mechanisms of ageing remain to be unexplored. Genetically, the timing of cell ageing entails the loss of telomeres (tips of chromosomes). However, the buildup of metabolic wastes resets the timing prematurely. Metabolic products accumulate from excess production or a shortfall of removal activity, which occurs in the various parts ....Characterisation of a novel neural-specific ATPase in cholesterol transport. Ageing is determined by both genetic and metabolic factors. To a large part, the detailed mechanisms of ageing remain to be unexplored. Genetically, the timing of cell ageing entails the loss of telomeres (tips of chromosomes). However, the buildup of metabolic wastes resets the timing prematurely. Metabolic products accumulate from excess production or a shortfall of removal activity, which occurs in the various parts of ageing cells in tissues such as brain. Traffic jams of cholesterol transport in the secretory pathway induce early ageing of the nerve cells. We investigate a novel mechanism controlling cholesterol transport in nerve cell ageing.Read moreRead less

Schizophrenia was estimated to cost approximately $1.85billion in 2001 (0.3% of GDP and nearly $50k for each of the 37,000 Australians with the illness). Over one third of the cost is borne by sufferers and their carers. Misdiagnosis and incorrect therapy are common. To date quantitative assessment of Schizophrenics has been impossible making this tool potentially invaluable. An accurate diagnostic test could facilitate earlier diagnosis, more accurate treatment plans, and prevention of debilitating psychotic episodes for the sufferer. By being able to monitor drug efficacy the community can benefit by reduced drug costs, confinement times and hastened new drug development. Read moreRead less
