Using Stem Cells And Bioengineered Scaffolds To Promote Regeneration Following Necrotic Brain Injury

Funding Amount
$710,857.00
Summary
A number of injuries, including stroke, result in tissue loss. Consequently promoting repair will require restoration of tissue structure, replacement cells and a supportive environment to promote integration of these new cells. This study will engineer and develop novel scaffolds that can replace tissue whilst additionally providing physical and chemical support for newly implanted stem cells. This work will be conducted in an animal model of stroke.
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
Knowledge, Identification And Exploitation Of Dopaminergic Axon Guidance Cues Will Improve Cell Replacement Therapy For ParkinsonÍs Disease.

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.
A Novel Treatment For Ischemic Stroke: Preclinical Assessment In The Nonhuman Primate

Funding Amount
$762,246.00
Summary
A major source of repair inhibition after brain injury is debris from dying cells, which contains proteins that hinder repair. This project will examine the expression of these proteins in a clinically-relevant model of ischemic stroke and determine if blocking the effect of these proteins neutralises their repair-inhibiting properties. If successful, there is likelihood that this drug, and method of delivery, could be translated into the human for treatment following an ischemic stroke.
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.
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.
Testing The Prion Hypothesis In Parkinson’s Disease Using A Novel In Vivo Model Of Α-synuclein Transmission

$622,555.00
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.

Summary
The Centre of Research Excellence in Stroke Rehabilitation and Brain Recovery will transform the stroke research and practice landscape in Australia, and accelerate the development of new interventions strongly supported by neuroscience. This unique collaboration will improve patient selection and rehabilitation research methods, create a training culture for the next generation of rehabilitation researchers and effectively implement proven cost effective interventions for Australians.
Selective Isolation And In Vivo Properties Of Dopamine Neurons Generated From Embryonic Stem Cells.

Funding Amount
$505,389.00
Summary
This research aims to develop a procedure that allows for the safe and effective use of stem cells as a therapy for Parkinson’s disease. It is based on the concept that new dopamine neurons, generated from stem cells, can be implanted into the brain of the patients in order to replace those lost to the disease, thereby improving motor function.
Restoration Of The Nigrostriatal Pathway In The Parkinsonian Brain

Funding Amount
$299,431.00
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.
