Wildlife and ecological resources such as Phillip Island's Little Penguin colony (with 500,000 visitors p.a.) and its environment are at the heart of Australia's ecotourism industry. If properly managed, such resources make significant contributions to the economy and can provide diverse employment opportunities for local communities. They also increase awareness of, and sensitivity to, environmental issues in general. Developing and implementing new and improved techniques for the rescue and rehabilitation of oiled wildlife and for the remediation of contaminated foreshore, apart from its inherent value, will contribute to the sustainability of such resources both at the national and international level.

Molecular Interactions of Chemical Agents with Ion-Channel Proteins. With a minimal number of functional units (proteins) viruses are able to replicate. All of these proteins are possible antiviral targets. In this project we wil1 focus on a short protein called Vpu found in membranes of the HIV-1 virus and aim to analyse the interaction of potential pore blocking compounds. It is essential to know exactly where they sit and how the overall structure of Vpu is affected. For this enterprise we wi ....Molecular Interactions of Chemical Agents with Ion-Channel Proteins.

In this project we wil1 focus on a short protein called Vpu found in membranes of the HIV-1 virus and aim to analyse the interaction of potential pore blocking compounds. It is essential to know exactly where they sit and how the overall structure of Vpu is affected. For this enterprise we will use nuclear magnetic resonance (NMR) spectroscopy. This information will serve as a springboard for future investigations of virus membrane proteins.

The induction of strong immune responses without side effects is a highly desirable goal in vaccine R&D. The recently developed adjuvant DCtag utilises unique properties of dendritic cells to boost both cellular and humoral immune responses without tissue damage. This project will identify the mechanisms of immune induction of DCtag using unique properties of our sheep cannulation model. This will allow further optimisation of DCtag adjuvanticity in sheep, which will then be applied to the delivery of a prototype peptide based vaccine against foot and mouth disease virus, a veterinary disease of global importance, hereby increasing Australia's leadership in biotechnology.Read moreRead less
Regulation of local lymphocyte trafficking and its role during infection. The study of early immune responses will contribute to the development of better vaccination strategies. In particular it will contribute by helping to understand the essential differences between reactogenicity and immunogenicity and how this relates to adjuvants. Using this understanding it will be possible to develop novel adjuvants that induce appropriate immunity with minimal side effects.
Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent ....Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent, but safer, NSAIDs. This project is aimed at using the results from new lead compounds to design NSAIDs with much greater efficacy and much less side effects than those currently available.Read moreRead less

Insect pests impose massive costs in food production, in human health and in the wellbeing of our companion animals. Chemical insecticides remain a major weapon in the control of these pests, but the use of insecticides has some downsides. The way in which insecticides kill insects is poorly understood and insecticide usage has negative impacts in the environment – the persistence of chemical residues and the killing of beneficial insects along with the pests. Further, insects become resistant to insecticides, so pest control is lost. This proposed research seeks to identify the ‘achilles heal’ in insect pests and to target them with new generation insecticides to gain safe, effective and sustainable control.Read moreRead less
Application of in vivo electroporation to DNA immunisation. The in vivo delivery of plasmid DNA induces immune responses to the encoded protein vaccine. In large animals including humans, DNA vaccination needs to be further improved before becoming a commercial reality, at least partially due to the very low levels of expression in vivo. In vivo electroporation has proven to be an effective way to enhance the level of protein expression and increase DNA vaccine efficacy.

In large animals including humans, DNA vaccination needs to be further improved before becoming a commercial reality, at least partially due to the very low levels of expression in vivo. In vivo electroporation has proven to be an effective way to enhance the level of protein expression and increase DNA vaccine efficacy. We combine enhanced in vivo expression using electroporation with the co-delivery of plasmids encoding cytokines to enhance and modulate DNA vaccine in sheep. We will apply our findings to bovine viral diarrhoea virus (BVDV), both as an animal model for humans and as an economically important diseases of livestock.Read moreRead less
