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.
Myelin Remodelling: A Novel Form Of Neural Plasticity

$605,849.00
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.
Mapping The Neural Circuits Involved In Appetite And Feeding Behaviour

Summary
My research project involves deconstructing the neural circuitry underlying feeding behaviour using innovative genetically-based methods. I aim to identify and characterise the major projections of the oxytocin-expressing neurons in the paraventricular hypothalamic nucleus, which have recently been identified as critical in the feeding neurocircuitry. This emerging field of research is predicted to transform our understanding and treatment of disorders such as obesity and anorexia nervosa.
Central Nervous System Dendritic Cells – Guilty Or Not Guilty?

Summary
The central nervous system although structurally and functionally unique, must be able to mount protective immunological responses. However, breakdown in local and central immunoregulatory processes can lead to clinically disabling inflammatory conditions such as uveitis and multiple sclerosis. This project will investigate the role of Dendritic cells in models of autoimmune diseases affecting the eye and brain. The data will greatly aid our ability to design new immunotherapies to treat these b ....The central nervous system although structurally and functionally unique, must be able to mount protective immunological responses.

Novel Pathomechanisms And Therapeutic Targets In Neurodegenerative Diseases

Funding Amount
$340,038.00
Summary
This fellowship will provide new insight into the molecular processes underlying onset and progression of common brain conditions, including Alzheimer’s disease, frontotemporal dementia and motor neuron disease. Furthermore, new therapeutic targets for these diseases will be developed and tested in model systems, to facilitate future translation into clinical application, and to overcome the lack of treatments.
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.
Problems in learning, memory and other complex mental processes are common to many brain disorders. This project will study the impact of mutations on a family of genes reported in autism and schizophrenia, on complex cognitive behaviours using novel behavioural technologies. This will not only shed fundamental insights into the specific mental processes regulated by these genes and their role in disease, but importantly provide novel targets for the development of therapies.
Novel Pathomechanisms And Therapeutic Approaches In Alzheimer's Disease And Related Dementias

Summary
Currently, over 200,000 Australians are affected by Alzheimer's disease (AD) or frontotemporal lobar degeneration (FTLD), causing a huge socio-economic damage. To overcome the lack of effective treatments, we need to understand the underlying causes and translate them into therapy. Using state-of-the-art cell culture and genetic mouse models, I will reveal fundamental processes in AD and related dementias, and develop tailored treatments to battle these devastating disorders.
Slowing Progression Of Alzheimer’s Disease By Modulating The Kynurenine Pathway

Summary
Chronic inflammation in the brain in known to be a factor in the progression of Alzheimer's disease. We are exploring if blocking a particular enzyme in a biochemical pathway involved in inflammation, can improve symptoms, or slow progression, of the disease in animal models of AD. If results are as expected, our proposal has the potential to generate a new a therapy for AD.
