The Role Of Neuronal Hyperactivity And Neurotrophic Factor Signalling In Synaptogenesis, Dendrogenesis And Neuron Death In Motor Neuron Disease

Summary
Using mice with mutant genes causing amyotrophic lateral sclerosis, we will test whether motor neuron hyper-excitability during early development causes excessive synapse and dendrite formation, ultimately leading to neuronal death. We will also test whether activity-dependent secretion of neurotrophic factors and activation of their receptors plays a role in this disease. This will show whether neuronal hyper-activity and neurotrophic factor signaling plays a causal role in this disease.
The Role Of BDNF In Central Nervous System Myelination

Summary
Multiple Sclerosis (MS) is the most common neurological cause of disability in young adult Australians. The cause of MS is unknown and therapies are limited to reducing inflammation, which does not address the major problem of the disease: loss of myelin. This project directly investigates how myelin is formed and will identify key mechanisms in this process, which may eventually be developed into treatments for diseases such as MS.
Defining The Function Of Two Discrete Precursor Cell Populations In The Adult Hippocampus: Potential For The Treatment Of Cognitive And Mood Disorders

Summary
Adult hippocampal neurogenesis plays a crucial role in fundamental cognitive processes such as learning and memory formation and mood regulation. Our laboratory has identified two discrete pools of quiescent stem and precursor cells in the adult hippocampus that can be activated by distinct mechanisms. This study will examine the functional properties of new neurons generated from these discrete pools and their role in improving behavioural outcomes associated with cognition and mood regulation
Pre-Clinical Studies Towards Cell-Based Approaches For Cortical Repair.

Summary
This project seeks to determine whether brain cells that die after stroke can be functionally replaced using cells grown in the laboratory from human stem cells. Current therapies for stroke aim to limit the damage but do not allow for actual recovery of brain function. By growing turning stem cells into specialised cells that match the ones lost after stroke, this project aims to restore motor function by transplanting these cells into the injured brain.
I am a neurologist and neuroscientist studying the causes and mechanisms of Parkinson's disease and the physiology in health and diseases of the nervous system affected by movement disorders
This proposal seeks to determine the therapeutic potential of stem cells for the treatment of brain injury early in life, for example as occurs in cerebral palsy. The project will test the capacity of implanted stem cells to both protect the brain and also to functionally replace cells lost to the injury in order to improve motor and cognitive function.
Using Stem Cells And Bioengineered Scaffolds To Promote Regeneration Following Necrotic Brain Injury

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.
New Projection Neurons Are Added To The Brain Throughout Life – Identifying Their Source And Function.

Summary
Scientists aim to use our body’s own stem cells to make new nerve cells for brain repair. There are two major types of nerve cell: long range and short range; and until now we did not know how to make new long range nerves. I recently discovered that a special type of brain stem cell, the OPC, makes new long range nerves throughout life. We are building on this discovery by trying to understand the signals that control this process in order to direct OPCs towards nerve regeneration.
Pre-clinical Steps Towards A Stem Cell Therapy For Parkinson's Disease.

Summary
A promising experimental therapy for Parkinson's disease is the use of stem cells that in order to replace the cells lost during the disease process. A challenge for this approach is that upon transplantation into the brain, in addition to the therapeutic cell types, there will also be unwanted cell types such as those that can form tumours. This proposal seeks to establish a novel strategy for removing those cells prior to transplantation.
