Summary
To reduce dementia burdens in the community, cost effective and targeted early regenerative strategies are critical. Engaging in frequent aerobic exercise is one strategy that can delay the onset and slow the progression of dementia. However, prescription is limited by an incomplete understanding of how exercise positively influences brain health. Here I will investigate the influence of current exercise levels, intensity and exercise environment on brain health in adults at risk of dementia.
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.
Implications Of Retinal Neurodegeneration In Alzheimer's Disease

Summary
Recent research has shown that “early signs” of Alzheimer ’s disease (AD) can be detected in the eyes. My research focus is to determine which particular changes in the retina are associated with AD. I will also investigate if blocking the production of beta amyloids (proteins produced in AD) in the eye will indeed help reduce their load in the brain and hence delay the onset of AD. Results from this research maybe used for early diagnosis and future medicinal studies that target the eye in AD.
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.
Dementia is the third leading cause of death in Australia and the single greatest cause of disability in the elderly. Current therapies for Alzheimer’s disease (AD), the most common form of dementia, are inadequate and fundamentally new treatment approaches are required. The aim of this proposal is to develop novel drug candidates for the treatment and prevention of AD and other neurodegenerative disorders by targeting a class of cell-surface receptors called G protein-coupled receptors (GPCRs).
Stand Up To Dementia: Reducing Prolonged Sitting To Improve Cognitive Function In Older Adults

Funding Amount
$603,901.00
Summary
Australia has an ageing population, resulting in more people being diagnosed with dementia. Prolonged sitting - (a behaviour that is very common amongst older adults) may increase the risk of cognitive decline and thus developing dementia. This study aims to further explore the relationship of sitting with dementia and cognitive function by using objective measures of sitting and also to develop programs and resources to reduce prolonged sitting which are informed by consumers.
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.
Improving Human FMRI Through Modeling And Imaging Microvascular Dynamics

Funding Amount

Summary
In this project we aim to establish a reliable vascular baseline to improve mapping of both small-scale functional architecture and large-scale brain networks in functional human brain mapping using MRI. By mapping the grey matter vasculature with high detail in both humans and animals, and by computing and matching of these atlases across species we will be able to validate this approach in vivo to confirm the better spatial specificity of the newly developed approach.
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.
Alzheimer’s disease (AD), is the most common form of dementia, accounting for between 50-70% of all cases. There is general agreement that current treatments for AD/dementia are inadequate so new treatment strategies are desperately needed. I am addressing these challenges by developing new technologies to generate next generation treatments for AD.
