Summary
In patients with multiple sclerosis, brain insulation is lost from nerves. This leads to permanent and progressive disability. We have identified a non-invasive method of magnetic stimulation, and have shown that it increases the number of new insulating cells added to the brain. In this study we will determine whether this new treatment can promote insulation repair in a model of multiple sclerosis.
Optimising Myelin Repair And Restoring Neuronal Function In The Demyelinated Brain

Summary
Multiple sclerosis is a disease of the brain and spinal cord caused by damage to white matter. In healthy brains, a substance in white matter called myelin insulates the axons (cables) of nerve cells, which speeds up electrical conduction. In MS, myelin is destroyed which impairs conduction and can lead to permanent loss of axons and nerve cells. To prevent this, we will test whether increasing electrical activity in nerve cells helps restore myelin by activating myelin-forming stem cells.
Targeting The Canonical Wnt Signalling Pathway To Promote Central Nervous System Remyelination In Vivo

Summary
Multiple Sclerosis (MS) occurs when immune cells attack the sheaths, called myelin, that cover and protect nerve connections. If myelin is damaged nerve cells cannot function properly, leading to severe disability. The brain has a group of cells that could potentially replace damaged myelin, but as MS worsens these cells are blocked in a state where they cannot help in repair. I will remove a signal specifically from these cells and determine if this unblocks them resulting myelin repair.
Defining The Basis Of Autoimmune Attacks Against Myelin To Better Target Treatment Of Demyelinating Disorders

Summary
Brain autoimmunity is a common and costly cause of neurological and psychiatric disability in children and adults. Exploring the autoimmune response that targets the brain is essential for accurate diagnosis, prognosis, and treatment. This project grant will identify and study the earliest autoimmune responses against the brain in children and adults. This will allow early and directed treatments that will not only prevent disability, but will also be life-saving.

Summary
In Multiple Sclerosis brain cells are damaged and myelin is lost in a process known as demyelination. Two proteins, called Gas6 and Protein S, can influence cells involved in MS, by signalling through proteins called TAMs. We have shown that Gas6 can affect the severity of demyelination in mice, and that TAMs can affect the response of cells to interferon-beta, a major MS treatment. We plan to further study the effects of these proteins during demyelination, and their interaction with interferon ....In Multiple Sclerosis brain cells are damaged and myelin is lost in a process known as demyelination.

Myelin Remodelling: A Novel Form Of Neural Plasticity

Summary
Myelin is the insulation of the central nervous system (CNS). We have demonstrated that CNS insulation is not fixed. It changes throughout life. This project aims to find out why this happens. In particular we will investigate the role of dynamic insulation in learning and memory, and examine the role of nervous system activity in promoting the addition of new insulation. This research will provide valuable insight into multiple sclerosis, Alzheimer's dementia and mental health disorders.
What Predicts The Progressive Phase Of Multiple Sclerosis

Summary
We have made major gains in our understanding of what causes MS. What has proven to be far more difficult is understanding the drivers of disability progression and conversion to progressive MS. The onset of progression heralds the accumulation of irreversible disability and is a critical time point to a person with MS. This grant aims to determine the lifestyle, environmental, genetic and epigenetic drivers of MS progression, using an internationally unique Australian MS longitudinal cohort.
Predicting Treatment Response To Onabotulinumtoxin-a In MS-related Tremor: A Combined Clinical, Electrophysiological And Neuroimaging Approach.

Summary
Shaking (tremor) of the upper limbs occur in many people with multiple sclerosis (MS). We have previously shown that botulinum toxin (Botox) injections could help reduce tremor. This study aims to study the effect of Botox in a larger group of people with MS and will include detailed MRI scans and electrical tremor monitoring tests to define the underlying changes in the brain that causes tremor. The results will help make Botox available as a tremor treatment for people with MS.
Multiple Sclerosis (MS) is an autoimmune disease often diagnosed in early adulthood. Outcomes very enormously, from mild to disabling. This fellowship supports research to improve outcome prediction using genetics and to examine different strategies to optimise treatment outcomes and safety. The main data source is MSBase, which tracks over 31000 people with MS globally and is based in the University of Melbourne's brain Centre at the Royal Melbourne Hospital.
Tremor And Cognition In Multiple Sclerosis: Implementing Novel Treatments And Computerized Monitoring Strategies.

Summary
This research program aims to study two disabling symptoms of multiple sclerosis namely upper limb shaking, or tremor, and memory dysfunction. The first project will develop a new treatment for MS arm tremor, Botulinum toxin injections, into routine clinical practice. The second project aims to make available a computerised test of memory that can be done in clinic waiting rooms or at home. This will help neurologists to rapidly pick up changes in memory in a person with MS and improve care.
