Investigating The Synergistic Role Of Brain-derived Neurotrophic Factor (BDNF) And Estradiol On Parvalbumin-mediated Cognitive Function: Relevance To Dementia

Summary
Estrogen-based therapy may improve cognitive functioning in dementia patients. However, more detailed knowledge is required to ensure safe and effective targeted treatment is provided. I propose to examine, in mouse models, the mechanistic functioning of estrogen signalling in key brain regions involved in cognition. Unravelling the way estrogen impart its beneficial effect can lead to the development of effective treatments for dementia and many other devastating neurological diseases.
New Nanoparticle Strategies For Efficient Delivery And Controlled Release Into The Brain

Summary
A key challenge for treating neurodegenerative diseases is delivery of drugs across the blood–brain barrier (BBB). This project will develop advanced BBB “nanoshuttles” based upon systematic investigation of BBB penetration mechanisms and near-infrared drug controlled release strategy. These delivery systems may facilitate diagnosis of brain diseases and on-demand release of drug cargos to diseased cells in the brain, offering the potential of a brand new localised therapy for brain diseases.
This Fellowship will develop novel diagnostic techniques in those patients who are at risk of developing Dementia and Parkinson’s Disease. Participants will also be encouraged to enrol in a brain donation program allowing detailed information for future correlations between symptoms and brain changes. This work will lead to the creation of a diagnostic matrix (At Risk Index) that will provide clinicians and researchers with tools to inform better diagnosis, prognosis and therapy.
Forging A New Understanding Of Iron In Neurodegenerative Disease.

Summary
Using the versatile model system, C. elegans, this proposal will define how normal functions of the brain become corrupted with age and hijacked by neurodegenerative diseases to cause dementia. Coupling specialised X-ray imaging only available at the Australian Synchrotron with the research excellence of the University of Melbourne, this Fellowship will provide a better understanding of normal ageing and how this relates to the development and progression of neurodegenerative diseases.
Regulation Of Cardiometabolic Disease By A Novel ATP Binding Cholesterol Transporter, ABCA8: A New Therapeutic Target?

Summary
Approximately 1.7 million Australians and 12% of the population in Singapore has type 2 diabetes (T2D). We have identified a cholesterol transporter, ABCA8, the absence of which produces symptoms similar to those seen in humans with T2D. The aim of this project is to understand the molecular basis of the diabetes symptoms in mice that do not have ABCA8 with a view to identifying this transporter as a drug target to reduce T2D and its complications, including heart attacks.
Determining The Clinical Effectiveness Of Antiviral Drugs Against Oseltamivir- And Laninamivir-resistant Influenza Viruses In Animal Models

Funding Amount
$388,067.00
Summary
Currently, the neuraminidase inhibitors are the only drugs that are effective against seasonal influenza viruses. However, viruses can develop resistance to these drugs. Using viruses with varied levels of resistance, the project will determine the effectiveness of different drug treatments in animal models. This will lead to better treatment for those patients seriously ill with drug-resistant influenza viruses.
Pericyte Dysfunction Limiting Energy Supply In Alzheimer's Disease

Summary
One possible cause of Alzheimer’s disease (AD) could be narrowing of small blood vessels (capillaries) within the brain, limiting blood flow and energy supply. Pericytes, a cell only on capillaries, maintain blood flow throughout the brain. I believe that pericytes may die in AD leading to an energy deficit and memory problems. I will test using human brains and animal models whether pericyte loss causes AD and how this is happening. Pericytes could provide a new therapy option for AD.
We need to think laterally to find effective treatments for people with dementia. Using relevant animal models and cutting-edge technology, my research investigates gene-environment interactions. In particular, my group is studying the pathophysiology of Huntington’s disease, a devastating progressive disorder with no current cure. By integrating my unique wide-ranging expertise and my extensive network of collaborators, I aim to explore mechanisms and to discover novel therapeutic strategies.
