Defensive behaviours elicited by predator odours. Rats display a powerful anxiety responses when confronted with the odours of predators such as cats. This response may occur even though rats have never encountered an actual predator before. This project aims to investigate the nature of this anxiety and the nature of the stimuli that produce it. The outcomes should be a better understanding of the neural basis and pharmacology of anxiety states and the identification of novel chemicals that hav ....Defensive behaviours elicited by predator odours. Rats display a powerful anxiety responses when confronted with the odours of predators such as cats. This response may occur even though rats have never encountered an actual predator before. This project aims to investigate the nature of this anxiety and the nature of the stimuli that produce it. The outcomes should be a better understanding of the neural basis and pharmacology of anxiety states and the identification of novel chemicals that have powerful rodent repellent properties. Such chemicals may be of great use in domestic and agricultural contexts where rodents are pests.Read moreRead less
Mechanism of transmission of calcium waves by glial cells. This research concerns determining the fundamental properties of cells that occupy about 70% of the brain, the glial cells. Two very important discoveries on glial cells have recently been made, namely that they can convey information in the form of patterns of waves and that they possess molecules on their surface membranes that have been implicated in psychotic disorders. One such molecule is called the D2 receptor and its malfunctioni ....Mechanism of transmission of calcium waves by glial cells. This research concerns determining the fundamental properties of cells that occupy about 70% of the brain, the glial cells. Two very important discoveries on glial cells have recently been made, namely that they can convey information in the form of patterns of waves and that they possess molecules on their surface membranes that have been implicated in psychotic disorders. One such molecule is called the D2 receptor and its malfunctioning has been implicated in schizophrenia. Our research will determine the way in which information is propagated in the glial system of the brain and also illuminate the function of several of the molecules found on the surface of the glial cells.Read moreRead less
A Century of Drugs: Science, Medicine, and Industry in the Development of Pharmaceuticals. This project explores collaborations between life scientists, physicians, and industrialists in the discovery of six major new drugs, between the 1890s and 1990s. The aim is to develop a primary source-based history, and two books as well as other writings communicating findings, on the mutual influences between academic life science, medicine, and the drug industry that have flowed from such collaboration ....A Century of Drugs: Science, Medicine, and Industry in the Development of Pharmaceuticals. This project explores collaborations between life scientists, physicians, and industrialists in the discovery of six major new drugs, between the 1890s and 1990s. The aim is to develop a primary source-based history, and two books as well as other writings communicating findings, on the mutual influences between academic life science, medicine, and the drug industry that have flowed from such collaborations. This history will provide fundamental insights into the relationship between biological knowledge and medical practice, and the social and intellectual consequences of the pharmaceutical industry's involvement with both clinical research and biological science.Read moreRead less
Development of a gene delivery system to access neuronal cells. Understanding the pathways for gene delivery and efficient expression will result in new knowledge in the areas of biotechnology and cell biology. This project will result in significant new information on vesicular trafficking pathways in neurons. An effective gene delivery system will realise significant commercial potential for our partner organisations and economic benefit to other Australian industry. This project aligns direct ....Development of a gene delivery system to access neuronal cells. Understanding the pathways for gene delivery and efficient expression will result in new knowledge in the areas of biotechnology and cell biology. This project will result in significant new information on vesicular trafficking pathways in neurons. An effective gene delivery system will realise significant commercial potential for our partner organisations and economic benefit to other Australian industry. This project aligns directly with the National Research Priority of "Promoting and maintaining good health" with a specific benefit for patients that suffer mental and physical degeneration and for their families.Read moreRead less
Neuron-microglia signalling mechanisms. This research concerns determining the fundamental mechanisms by which one of the principal non-neuronal cells in the brain , the microglial cell, interacts with neurons to change their properties. The correct functioning of neural networks is necessary for our normal behaviour. Such networks can be disrupted and indeed destroyed by the release of inflammatory molecules from microglial cells. In this work the way in which anti-inflammatory molecules are re ....Neuron-microglia signalling mechanisms. This research concerns determining the fundamental mechanisms by which one of the principal non-neuronal cells in the brain , the microglial cell, interacts with neurons to change their properties. The correct functioning of neural networks is necessary for our normal behaviour. Such networks can be disrupted and indeed destroyed by the release of inflammatory molecules from microglial cells. In this work the way in which anti-inflammatory molecules are released from the microglia will be elucidated, thus providing insight into how to prevent the destructive actions of the inflammatory molecules on the nervous system.
