Summary
This project aims to elucidate the mechanisms by which macrocyclic lactones bind to brain ion channel receptors. This will reveal fundamental new insights into the operation of these receptors and will have important implications for the design of novel treatments for a variety of central nervous system disorders.

Summary
Schizophrenia (SCZ) is a complex psychiatric disorder that appears in male and female around adulthood. To date there is no clear pathological symptoms to identify SCZ individuals and place them in a specific group. Some proteins are genetically associated with this disease. I will investigate how some of these proteins disturb the function of the brain in human. My recent published data shows decrease of one of the proteins in the brain of SCZ group.

I will investigate how some of these proteins disturb the function of the brain in human. My recent published data shows decrease of one of the proteins in the brain of SCZ group. My project may help develop novel and more selective therapies with less side-effects.Read moreRead less
The Role Of A Presenilin 2 Truncation (PS2V) In Alzheimer's Disease

Summary
The Presenilin and APP proteins are centrally important in inherited, early onset Alzheimer's disease. We have discovered that a shortened form of Presenilin protein, "PS2V", appears to increase specifically the rate at which the APP protein is cleaved to produce the "Amyloid beta" protein fragment that is found in Alzheimer's disease brains. This occurs when brain cells are under oxidative stress. Understanding this process will facilitate development of appropriate therapeutic strategies for t ....The Presenilin and APP proteins are centrally important in inherited, early onset Alzheimer's disease.

Summary
Alzheimer’s disease and beta amyloid toxicity: Alzheimer’s disease (AD) is the most common form of dementia and is characterized by progressive memory loss, confusion, and cognitive deficits. In 2011, an estimated 269,000 Australians are currently living with dementia and without a significant medical breakthrough soon, it is anticipated that this will rise to about 981,000 by 2050
Exploring Scanning Ultrasound (SUS), A Novel Method To Treat And Prevent Neurodegenerative Disease

Funding Amount

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.
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.

Summary
The dystonias represent a group of movement disorders characterised by sustained muscle contraction, resulting in twisting and abnormal postures. Current treatment regimes may provide some measure of symptomatic relief, but are often unsatisfactory and limited by adverse side effects. The prevalence of dystonia is estimated at approximately 300 cases per million population. Dystonia is a complex disorder, the causes and disease mechanisms are not well understood.

Current treatment regimes may provide some measure of symptomatic relief, but are often unsatisfactory and limited by adverse side effects. The prevalence of dystonia is estimated at approximately 300 cases per million population. Dystonia is a complex disorder, the causes and disease mechanisms are not well understood. However, in the past 10 years several genes have been identified that can cause dystonia. The overall aim of this proposal is to characterise a gene that causes dystonia when disrupted. Understanding the function of this gene may significantly advance our understanding of this disorder. Using these results, we aim to model dystonia in cellular and animal systems; these may provide powerful insight into the molecular pathway(s) perturbed in dystonia and a means to develop novel therapeutic approaches to alleviate or prevent the disorder.Read moreRead less

Summary
In the proposed research, three novo approaches for drug discovery will be explored: 1) The important neurodegenerative disease relevant protein JNK3 crystals will be used as the probe to fish out the potential inhibitors from Traditional Chinese Medicine (TCM); 2) Instead of individual drug components, the mixture of TCM will be used directly; 3) The composition of a TCM library are not randomly chosen but have been used in China for hundreds to thousands of years in curing neurodegenerative di ....In the proposed research, three novo approaches for drug discovery will be explored: 1) The important neurodegenerative disease relevant protein JNK3 crystals will be used as the probe to fish out the potential inhibitors from Traditional Chinese Medicine (TCM); 2) Instead of individual drug components, the mixture of TCM will be used directly; 3) The composition of a TCM library are not randomly chosen but have been used in China for hundreds to thousands of years in curing neurodegenerative disease.Read moreRead less
