Restoration Of The Nigrostriatal Pathway In The Parkinsonian Brain

Summary
Many obstacles exist for cell transplantation in Parkinson's disease; namely poor restoration of the host brain circuitry due to incorrect graft placement. This results in incomplete motor function and unwanted side effects. Through iterative studies we endeavor to restore this circuitry by placing grafts in the appropriate location and promoting their survival and growth-integrations. This will require: optimizing the donor tissue and exposure of the graft to growth stimulating factors.
Seizures appear unpredictable and greatly affect the quality of all aspects of life for patients with epilepsy and their carers. New advances in complex systems theory suggest that transitions from normal brain activity to seizures are preceded by measurable changes in the brain’s responses to stimuli, known as critical slowing. Measurement of critical slowing will enable prediction of seizures, providing a warning system, and possibly an opportunity to deliver preventative therapies.
Testing The Prion Hypothesis In Parkinson’s Disease Using A Novel In Vivo Model Of Α-synuclein Transmission

Summary
Parkinson’s Disease (PD) is a debilitating neurological disease with no cure. Recently it has been discovered that the disease can spread through the brain. We have developed the worlds first animal model to study exactly how the disease propagates inside of neurons during this spread. We will use the model to answer key questions about this critical stage of disease spread, knowledge that is essential for the development of successful therapies to prevent disease progression.
Vascular Cognitive Risk Score: Quantifying The Vascular Burden In Alzheimer's Disease

Summary
What causes dementia in a patient presenting to a clinic is often uncertain. While there are exciting potential treatments in the pipeline, we need to understand the cause of the disease in a specific patient to make correct treatment decisions. Stroke and other vascular diseases of the brain cause a significant proportion of dementia in the community. Using MRI scanning technology, this project will quantify this burden in a given patient by developing a ‘vascular cognitive risk' (VCR) score.
Standardising Protocols For The Differentiation And Integration Of Human Pluripotent Stem Cell-derived Neural Transplants In Parkinson's Disease

Funding Amount
$987,664.00
Summary
Clinical trials have shown that transplanting dopamine neurons (specific nerve cells) into the brain of Parkinson’s disease patients can improve symptoms. Trials use fetal tissue for implantation, which is unsustainable and highly variable. This proposal will examine stem cells as an alternative. We will establish a reliable protocol to instruct human stem cells to become dopamine neurons, develop methods to select these cells and, examine the integration of these transplanted cells in the brain
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.
Knowledge, Identification And Exploitation Of Dopaminergic Axon Guidance Cues Will Improve Cell Replacement Therapy For ParkinsonÍs Disease.

Funding Amount
$481,797.00
Summary
Many obstacles exist for cell transplantation in ParkinsonÍs Disease; namely poor graft survival, restoration of appropriate circuitry and adequate nerve fiber growth from new cells. Using knowledge of how neural circuits are established during fetal development, we will attempt to recapitulate these events following transplantation. Further, we will identify new and novel cues in regulating the connectivity and growth of these nerve fibers.
Understanding Neuroinflammation In Alzheimer's Disease

Funding Amount
$1,043,216.00
Summary
This project opens a new line of enquiry into the cellular signalling mechanisms involved in the progression of AD and establishes whether targeting the involvement of type-1 IFN signalling influences the evolution of AD. New and novel approaches are clearly required to treat AD. Importantly, we believe that neuroinflammation is common to all causes of dementia and targeting the neuroinflammatory pathways has much wider implications than targeting the primary causative pathway.
Targeting Tau Phosphorylation To Treat And Prevent Acquired Epilepsy, Neurodegeneration And Neuropsychiatric Disease Following A Brain Injury

Summary
This project will explore a new approach to the prevention and treatment of epilepsy and the associated mental health disorders following a brain injury. This involves inhibiting pathological forms of the Tau protein, which has been implicated in the development of epilepsy and neurodegeneration. The drug that will be tested in this study has already been demonstrated to be safe and well tolerated in humans, meaning that a positive result from these studies could be expediently translated into c ....This project will explore a new approach to the prevention and treatment of epilepsy and the associated mental health disorders following a brain injury.

Exploring Scanning Ultrasound (SUS), A Novel Method To Treat And Prevent Neurodegenerative Disease

Funding Amount
$765,708.00
Summary
We developed a novel scanning ultrasound (SUS) protocol that clears toxic protein aggregates and restores memory function in mouse models of Alzheimer's disease (AD), without the need for therapeutic agents. Here we aim to determine whether SUS has preventative potential, whether there are synergistic effects, and whether a therapeutic antibody combined with SUS leads to an enhanced therapeutic outcome. Together this will guide the development of an ultrasound therapy in AD patients.
