The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Nix Mediated Mitophagy: A New Therapeutic Approach To Parkinson's Disease
Funder

Funding Amount
$674,428.00
Summary
Parkinson’s disease (PD) is the most common neurodegenerative movement disorder in the world. A key problem in PD is that affected neurons lose energy and then die. We have discovered that by recycling mitochondria (the parts of the cell that produce energy), we can protect neurons from dying and restore function. This project will determine whether mitochondrial recycling mediated by Nix can restore energy and prevent neuronal loss. This would represent a new therapeutic approach to treat PD.
Correlating Multiple Sclerosis Risk SNPs With Immune Cell Gene Expression

Funding Amount
$789,386.00
Summary
In Multiple Sclerosis (MS), the immune system repeatedly attacks the brain and spinal cord. In the last three years, rapid progress has been made in understanding genetic risk factors for MS, and more than 20 are known, but their function is not understood. The proposed study will recruit patients with MS and healthy controls to isolate five major immune cell types, and will assess how risk genes influence these cells. We hope to obtain a much better picture of how genetic risk factors for MS ac ....In Multiple Sclerosis (MS), the immune system repeatedly attacks the brain and spinal cord.

A Longitudinal Neuroimaging Study Investigating Reorganisation Of Cerebellar-cerebral Networks In Friedreich Ataxia

Funding Amount
$816,908.00
Summary
Friedreich ataxia (FRDA) causes debilitating motor and cognitive deficits. We propose a longitudinal multi-modal magnetic resonance (MR) imaging study to measure different types of tissue in the brain in this disease. We seek to understand how the brain reorganises itself due to cell loss in the spinal cord, cerebellum and cerebral cortex. This study will establish sensitivity of a range of MR imaging measures as potential biomarkers for use in large multi-centre drug trials in this disease.
Modulating Heat Shock Protein Expression In Skeletal Muscle To Improve The Pathophysiology Of Muscular Dystrophy

Funding Amount

Summary
Duchenne muscular dystrophy (DMD) is the most common and severe form of muscular dystrophy. Dystrophic muscles are fragile, prone to injury, and regenerate poorly after damage. Defective calcium handling has been implicated in these processes. We have revealed that upregulating levels of stress proteins called _heat shock proteins� (HSPs) can improve calcium regulation in muscular dystrophy. Modulating the HSP response has significant potential to delay the onset or slow the progression of DMD.
Implications Of Retinal Neurodegeneration In Alzheimer's Disease

Funding Amount

Summary
Recent research has shown that “early signs” of Alzheimer ’s disease (AD) can be detected in the eyes. My research focus is to determine which particular changes in the retina are associated with AD. I will also investigate if blocking the production of beta amyloids (proteins produced in AD) in the eye will indeed help reduce their load in the brain and hence delay the onset of AD. Results from this research maybe used for early diagnosis and future medicinal studies that target the eye in AD.
Carolyn Sue is a neurologist and scientist investigating the role of disturbed mitochondrial function in human disease. Mitochondria play a key role in maintaining energy levels and the cell’s health. When this function is impaired, cells may degenerate or die, and thus cause human disease. Dr Sue’s research is aimed at seeking improved treatments to treat mitochondrial disease and to further understanding about how brain cells degenerate when the mitochondria fail.
How Does Fampridine Affect Upper Limb Function In Multiple Sclerosis?
Funder
National Health and Medical Research Council
Funding Amount
$113,237.00
Summary
Multiple sclerosis (MS) is a common and disabling neurological disease affecting thousands of young Australians. In 2011 Fampridine received TGA approval for walking impairment in MS, but its mechanism of action is unknown and its effects on domains other than lower limb function remain untested. Our study will test whether Fampridine improves upper limb impairment in MS patients and will use electrophysiological measures of central nervous system conduction to uncover its mechanism of action.
Hand Splinting And Motor Training In Cerebral Palsy
Funder

Funding Amount
$80,952.00
Summary
As many as 1 in 500 children have cerebral palsy or a brain injury. 1 in 3 cannot walk, 1 in 4 cannot talk, 3 in 4 are in pain. These conditions impact on a child's ability to use their hands to touch, play, draw and explore. Hand use is the single most important factor for determining a child's long term independence into adulthood. This project explores the most effective treatment approach to enable children to use their hands to reach the goals they want to achieve and live meaningful lives.
Examining The Specific Vulnerability Of Dopaminergic Cells To Bioenergetic Defects Using Patient-derived Induced Pluripotent Stem Cells As A Model Of Parkinson’s Disease
Funder
National Health and Medical Research Council
Funding Amount
$112,366.00
Summary
The project will develop new cell models of Parkinson's disease utilising the recently discovered technique of inducing pluripotent stem cells from adult skin cells and differentiating them into the type of neurons that are affected in Parkinson's disease. The novel method will allow further insights to be gained into the molecular pathways involved in the disease and facilitate a search for means to rescue these cells from neurodegenerative processes.
