Funding Amount
$600,771.00
Summary
Dementia and mental illness are significant social and economic burdens worldwide and knowledge of underlying causes and more effective therapies are required. Our research is using preclinical models to characterize a little studied neural network in the control of arousal states, rhythmic brain activity, and learning and memory. Our findings could advance the development of improved treatments for cognitive deficits in degenerative, age-related and psychiatric disorders.
Ascending Control Of Behavioural State And Cognition - Role Of Nucleus Incertus And Relaxin-3 Transmission

Summary
Mental illness and dementia are significant social and economic burdens worldwide and knowledge of their underlying causes and more effective therapies are required. Our research aims to use pre-clinical models to characterize a little studied neuronal network implicated in control of brain theta rhythm activity, which could lead to improved treatment of neuropsychiatric diseases such as anxiety and depression, and degenerative cognitive decline.
Controlling Neuroinflammation In Alzheimers Disease

Summary
Alzheimer’s disease (AD) is the most common neurodegenerative disorder worldwide, with 269,000 Australians currently diagnosed with AD and is expected to soar to about 981,000 by 2050. AD accounts for greater than 60% of all cases of dementia. This grant investigates the role that neuroinflammation plays in the progression and exacerbation of AD and will identify new therapeutic strategies to combat this insidious disease.
The Role Of Meninges In Midbrain Dopamine Development

Summary
Dopamine neurons are important for the control of movement, emotion and cognitive function, and are affected in a number of disorders such as Parkinson’s disease. Instrumental in improving our knowledge of disease etiology and the development of new therapies will be a greater understanding of how these cells are initially born during development. This project examines the role of the brain’s meninges in dopamine development and repair and will identify proteins and signaling pathways involved.
Understanding The Molecular Basis Of Central Nervous System Myelination

Funding Amount
$408,388.00
Summary
Oligodendrocytes are the cell type in the central nervous system that produce myelin, the insulating layer around nerve cells. Loss of oligodendrocytes and myelin are key features of multiple sclerosis. This project aims to clarify the mechanisms that control the myelination of nerve cells during normal development, allowing the development of strategies to promote myelin repair in human diseases such as Multiple Sclerosis.
Investigating Underlying Mechanisms Linking Type 2 Diabetes With Alzheimer’s Disease Pathology

Funding Amount
$701,950.00
Summary
With type-2 diabetes representing a major risk factor for neurodegenerative diseases such as Alzheimer's disease, it is important to understand the underlying mechanisms. This project will provide significant insight into how T2D impacts the brain with a focus on how deficiencies in brain inuslin signaling drives neurodegeneration. We will also evaluate novel inuslin like molecules at improving brain insulin siganling and preventing or slowing down the neurodegenerative process.
Neuron To Glia Signalling: Learning How Synaptic Signalling Can Promote CNS Remyelination

Funding Amount
$609,650.00
Summary
An immature cell type in the brain, known as the oligodendrocytes progenitor cell (OPC), receives direct electrical communication from neurons. This communication regulates the behavior of the OPC, affecting its ability to divide and generate new brain cells. This project will identify the signaling molecules that guide the OPC to for this specialized contact with the nerve cell. Understanding this communication has important implications for the treatment of Multiple Sclerosis.
Assessing The Role Of The N-terminus Of The Prion Protein, Emphasising Constitutive Cleavage, In Normal Function And Pathogenesis, As Well As Defining The Relationship Between Intensity Of Surveillance And Sporadic CJD Incidence.

Summary
As a neurologist undertaking research into prion diseases over an extended period, I have been able to lead and participate in many projects that have made significant contributions, such as validation of new diagnostic tests for Creutzfeldt-Jakob disease (CJD), assessment of potential therapeutics, provide insights into the normal function of the prion protein and the underlying pathways causing cellular damage and determine the real significance of apparent clusters of sporadic CJD.
The Role Of BMP Signalling During Chronic Demyelination And Myelin Repair

Summary
Multiple sclerosis (MS) is the most common neurodegenerative disease affecting young adults. It is a disease that kills myelin cells, which are important support cells for neurons and critical for neuronal function. This research investigates the role of a specific signaling pathway with respect to myelin cell production and repair with the ultimate aim of identifying regenerative therapeutics for MS.
