Summary
The origins of the brain injury that arises from stroke remain a matter of enormous interest. Our work suggests that a poorly understood form of cell death, termed necroptosis, contributes to injury to the brain following stroke. In addition to developing an advanced understanding of this process, we will use drugs developed at the Walter and Eliza Hall Institute to test whether blocking this process might be a plausible therapeutic strategy in stroke patients.
Structure-based Drug Design For Neuroprotection From Traditional Chinese Medicine

Summary
In the proposed research, three novo approaches for drug discovery will be explored: 1) The important neurodegenerative disease relevant protein JNK3 crystals will be used as the probe to fish out the potential inhibitors from Traditional Chinese Medicine (TCM); 2) Instead of individual drug components, the mixture of TCM will be used directly; 3) The composition of a TCM library are not randomly chosen but have been used in China for hundreds to thousands of years in curing neurodegenerative di ....In the proposed research, three novo approaches for drug discovery will be explored: 1) The important neurodegenerative disease relevant protein JNK3 crystals will be used as the probe to fish out the potential inhibitors from Traditional Chinese Medicine (TCM); 2) Instead of individual drug components, the mixture of TCM will be used directly; 3) The composition of a TCM library are not randomly chosen but have been used in China for hundreds to thousands of years in curing neurodegenerative disease.Read moreRead less
Site-specific Tau Phosphorylation To Treat And Understand Alzheimer’s Disease

Summary
Alzheimer’s disease (AD) is the most common form of dementia. Unfortunately, current therapies are ineffective. Our laboratory has made an important contribution to understanding the events that lead to brain cell malfunction in AD. I recently found a novel concept that changes the view of AD completely. In the next 3 years, I aim to develop therapeutic tools based on this novel concept and find out more about how it can protect brains from AD.
The Role Of Meninges In Midbrain Dopamine Development

Funding Amount
$378,311.00
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

National Health and Medical Research Council
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
Funder

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

Funding Amount

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.
