Synthesis, Biological Interactions and Toxicity Studies of Precisely Engineered Nanoparticles. The proposed benefits of nanotechnology for industries from material sciences, to bioengineering, energy and the environment are currently driving unprecedented growth in this technology world-wide. Some of these benefits are borne out of the unique properties that different nanoparticles exhibit. However, if nanomaterials pose a threat to the health and well-being of the community, then their risks ....Synthesis, Biological Interactions and Toxicity Studies of Precisely Engineered Nanoparticles. The proposed benefits of nanotechnology for industries from material sciences, to bioengineering, energy and the environment are currently driving unprecedented growth in this technology world-wide. Some of these benefits are borne out of the unique properties that different nanoparticles exhibit. However, if nanomaterials pose a threat to the health and well-being of the community, then their risks may outweigh their benefits. This project will identify those characteristics of nanoparticles that can lead to adverse effects and therefore pose a danger to the general community. By defining these characteristics, appropriate changes in nanomaterial production can be considered by industry to minimise these dangers.Read moreRead less

The aim of this project is to establish the South Australian Facility for Advanced Molecular Imaging. The Facility builds on existing expertise and cooperation between the collaborating institutions to expand our capability in advanced analytical confocal microscopy of a wide range of materials from living cells to artificial surfaces. New state-of-the-art microscopes will allow the direct quantitative analysis of molecular interactions with high temporal and spatial resolutions. This will advance: understanding the regulation of cellular signalling, gene expression and growth in normal and pathological conditions; development of biosensor technology; and the application of new biomaterials in medicine and industry.Read moreRead less
Determinants of Expression, Assembly and Function of the Noradrenaline Transporter. The noradrenaline transporter protein that is the focus of this project is important for mental health because it belongs to the family of proteins where psychostimulants, such as cocaine, and drugs used in the treatment of depression act. The project will lead to exciting advances in our understanding of how the structure of this protein controls its functions, and potentially to the design of better antidepress ....Determinants of Expression, Assembly and Function of the Noradrenaline Transporter. The noradrenaline transporter protein that is the focus of this project is important for mental health because it belongs to the family of proteins where psychostimulants, such as cocaine, and drugs used in the treatment of depression act. The project will lead to exciting advances in our understanding of how the structure of this protein controls its functions, and potentially to the design of better antidepressant drugs and to the design of drugs to prevent the effects of cocaine.Read moreRead less
Exploitation of a Novel Drug Target for Controlling Animal Trypanosomiasis. Trypanosomiasis greatly reduces livestock productivity in countries where it is endemic and is a threat to livestock and native wildlife in countries such as Australia where it is exotic but there is a risk of entry. New trypanocidal drugs with different modes of action are urgently needed to overcome growing resistance. This project aims to characterise trypanosome tubulin and, with this information, produce new tubulin ....Exploitation of a Novel Drug Target for Controlling Animal Trypanosomiasis. Trypanosomiasis greatly reduces livestock productivity in countries where it is endemic and is a threat to livestock and native wildlife in countries such as Australia where it is exotic but there is a risk of entry. New trypanocidal drugs with different modes of action are urgently needed to overcome growing resistance. This project aims to characterise trypanosome tubulin and, with this information, produce new tubulin-binding compounds for assessment in vitro and in vivo. Upon completion of the project it is expected that drug binding sites on trypanosome tubulin will be characterised and at least one candidate for clinical trials identified.Read moreRead less

Novel insecticidal neurotoxins from Australian spider venoms. Insecticidal toxins have considerable potential as novel biopesticides to combat the evolution of widespread insect resistance to classical chemical pesticides. This problem is increasing both in Australia and internationally.

Our laboratories will isolate neurotoxins from spider venoms, determine thei ....Novel insecticidal neurotoxins from Australian spider venoms. Insecticidal toxins have considerable potential as novel biopesticides to combat the evolution of widespread insect resistance to classical chemical pesticides. This problem is increasing both in Australia and internationally. This study aims to isolate and pharmacologically characterise potent and selective insecticidal neurotoxins from Australian arachnids. Our laboratories will isolate neurotoxins from spider venoms, determine their selectivity in insect and mammal bioassays, determine their primary and tertiary structures, and investigate their structure-function relationships by electrophysiological techniques. These functional and structural data will allow the future engineering, by molecular or synthetic procedures, of viral biopesticide analogues with increased potency, stability and selectivity.Read moreRead less

There is no vaccine for malaria and current drugs are failing, contributing to millions of malaria-related deaths each year. The aim of this project is to develop new drugs to address this significant global health issue. This project will focus on drugs that act in novel ways to existing malaria drugs by targeting enzymes that are involved in altering gene expression in the parasite. These kinds of enzymes are recognised drug targets in other diseases such as cancer. The outcomes of this project will include advances in malaria drug development that build on Australian drug discovery efforts, seeding further funding opportunities from industry and other sources and contributing research training and capacity building in Australia.Read moreRead less
Molecular evolution and toxinology of colubrid snake venom toxins. This project proposes to examine the origin and evolution of venom systems in advanced snakes (Caenophidia) focusing on the colubrid radiation comprising the rear-fanged species. Demonstration by us of the presence of a potent postsynaptic neurotoxin in the Durvenoy's secretions of the Asian ratsnake Elaphe radiata, an archetypal non-venomous colubrid species, forced a fundamental rethink of venom evolution. The toxin is homologo ....Molecular evolution and toxinology of colubrid snake venom toxins. This project proposes to examine the origin and evolution of venom systems in advanced snakes (Caenophidia) focusing on the colubrid radiation comprising the rear-fanged species. Demonstration by us of the presence of a potent postsynaptic neurotoxin in the Durvenoy's secretions of the Asian ratsnake Elaphe radiata, an archetypal non-venomous colubrid species, forced a fundamental rethink of venom evolution. The toxin is homologous with the three finger toxins, previously thought unique to elapids, and supports the role of venom as a key evolutionary innovation in the diversification of advanced snakes. This project extends this work to other species and toxin families.Read moreRead less
Characterisation of two-pore domain potassium channels: structure-function studies of the M1-P1 loops of TASK channels. TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers.

TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers. The in depth structural and functional characterisation of this class of potassium channels is of great importance as they are interesting targets for new therapeutic developments. Advancement of knowledge in the structure and function of these channels will underpin drug targeting that will aid preventative healthcare, allowing Australians to age well and age productively.Read moreRead less
