Summary
Epigenetic marks are changes made to the DNA which help genes to be switched off in some cells and switched on in others e.g. for elastin to be switched on in skin and off in blood. Epigenetic marks are critical to normal development. We are interested in the genes that are necessary to add epigenetic marks to the DNA and understanding how the many genes involved in this process co-operate at the molecular level to switch genes off.
Circadian Clock Regulation Of Dendritic Cell Metabolism And Function

Summary
Immunological and metabolic parameters change with the time of day, and are known as circadian rhythms. These fluctuations are critical for host adaptation to the environment and anticipate any increased risks of tissue damage and infection that accompany changes in activity and feeding. How the molecular circadian clock influences innate control of adaptive immunity is unknown. We will investigate how circadian proteins influence immune function through their sensing of nutrient and metabolic
Altering Meal Times To Reverse The Metabolic Consequences Of Shift Work

Summary
Shift work disrupts the internal body clock, which increases the risk for obesity and type 2 diabetes. Our research demonstrates meal timing plays an important role in this metabolic disturbance. Data from animal studies suggests that the adverse consequences of shift work can be reduced by eating only during the day. This study will investigate if this also occurs in humans, potentially leading to a straightforward solution to reduce the burden of chronic diseases in shift workers.
Utilising Functional Magnetic Imaging To Predict Pre-clinical Parkinson�s Disease In Patients With Idiopathic Rapid Eye Movement Sleep Behaviour Disorder

Summary
In an ageing Australian population a rise in the number of people with neurodegenerative conditions, such as Parkinson's Disease (PD) is inevitable. The ability to accurately identify those people who are destined to develop such diseases, might offer a mechanism by which such progression could be aborted. This project will seek to identify a reliable method whereby cases of PD could be detected several years before they can currently be diagnosed.
The Retina As A Chemogenetic Target For The Treatment Of Depression

Summary
Treatments for depression are often poor because they lack selectivity. By inserting receptors that respond to an inert drug, Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) can turn on-or-off very specific classes of cells, providing an exciting treatment direction for depression and other neuropsychiatric diseases. The long term goal of this project is to create a highly effective DREADD-based treatment for depression, which is activated by either eye drops or a pill.
Hyper-sensitivity Of The Circadian System To Light In Delayed Sleep Phase Disorder

Summary
Delayed Sleep Phase Disorder (DSPD) is a circadian rhythm sleep disorder characterized by a difficulty in initiating sleep at night and difficulty in waking at times required for work or school. It is associated with excessive daytime sleepiness, reduced academic and work performance, increased anxiety and depression and reduced quality of life. This study examines increased sensitivity of the brain's 24-hour biological clock to light as a cause of the abnormal timing of sleep in DSPD.
Sleep-wake Disturbances And Cardio-metabolic Dysfunction In At Risk Dementia: A Novel Pathway In Neurocognitive Decline’
Funder

Funding Amount
$558,305.00
Summary
Age-related sleep and circadian disturbance and cardio-metabolic dysfunction are associated with an increased risk of dementia. This research aims to delineate the pathway in which sleep and circadian disturbances and cardio-metabolic dysfunction promote cognitive decline during the ‘at risk’ dementia phase. This will improve our understanding of key processes in cognitive ageing ultimately leading to the development of targeted intervention programs in the quest to delay the onset of dementia.
