Unravelling The Behavioural And Brain Mechanisms Of Compulsive Disorders, And New Ways To Treat Them
Funder

Funding Amount
$635,076.00
Summary
Disorders of compulsion, such as obsessive-compulsive disorder and substance use disorder, are chronic, debilitating, and present a significant cost to the individual and to society. Together, these disorders affect more than 10% of the population. Moreover, 40-60% of these individuals are resistant to current treatment. The current project is aimed at improving the preclinical research underlying our understanding the behavioural and brain mechanisms of such disorders and how to treat them.
Determining The Impacts Of COVID-19 Restrictions On People Who Use Drugs
Funder
National Health and Medical Research Council
Funding Amount
$429,228.00
Summary
COVID-19 has resulted in unparalleled government interventions to close borders and restrict social interactions which have major implications for illicit drug supply, procurement and use practices, as well as responses. People who use drugs will be profoundly impacted by COVID-19 and so our study will leverage existing data collections to compare drug use practices and consequences before, during and after the COVID-19 interventions to determine COVID-19 impacts on people who use drugs.
Understanding Sex Differences In Alcohol Use Disorder: The Role Of Stress And Neuropeptides

Funding Amount
$692,106.00
Summary
Alcohol use disorders (AUD) are an emerging issue in women, yet there is little understanding of the how the male and female brains differ in response to excessive alcohol consumption. In pilot studies, we have found that deletion of a specific brain chemical causes differences in the way male and female mice consume alcohol in excess. We will further characterise this system and test new approaches to reduce the desire to consume alcohol.
Emerging Drugs Network Of Australia: A Coordinated Toxicosurveillance System Of Illicit Drug Use In Australia To Enable Rapid Detection And Harm Reduction Responses Via An Early Warning System
Funder
National Health and Medical Research Council
Funding Amount
$3,722,731.00
Summary
The Emerging Drugs Network of Australia brings together emergency physicians, toxicologists and forensic laboratories across the country to build a national surveillance and early warning system of illicit and emerging drugs. Our innovative approach will use laboratory confirmed data to identify the specific drugs resulting in emergency department presentations, and use this information to inform rapid, evidence-based public health responses to reduce further drug-related harm in the community.
Intergenerational Impacts Of Paternal Immune Activation On Brain Function And Dysfunction
Funder
National Health and Medical Research Council
Funding Amount
$997,690.00
Summary
We recently discovered that infection of male mice with a parasite (Toxoplasma gondii) before conception can change the epigenetic information in the sperm and alter behaviour of the offspring. This is the first evidence that pathogenic infection in males can affect the next generation. We will investigate how infection with other major pathogens, including bacteria and the virus causing COVID-19, may affect sperm epigenetics and offspring health, including their brain function and dysfunction.
Narcolepsy With Cataplexy: A Brain Orexin Replacement Strategy
Funder
National Health and Medical Research Council
Funding Amount
$810,784.00
Summary
Narcolepsy with cataplexy is a debilitating, life-long sleep-wake disorder, caused by the irreversible loss of the brain peptide 'orexin'. There is no satisfactory and safe treatment. We aim to develop an orexin analogue, delivered directly to the brain of sheep (relevant in size and translatable to patients) by a programmable pump to timely activate the orexin 'wake-up' switch. This innovative precision medicine project will significantly improve the quality of life of narcolepsy patients.
Creating A Phenotypic Catalogue Of Synaptic Vesicle Cycling Disorders
Funder
National Health and Medical Research Council
Funding Amount
$876,975.00
Summary
Developmental disorders affect 2-5% of children. In order to understand how these mutations will likely affect neurological function in these individuals, and to develop a tailored care and treatment program, we must first understand how these mutations affect neuronal communication. This research program will identify the underlying cause of neurological dysfunction in a subset of these disorders (synaptic vesicle cycle disorders), affecting 1200-3000 children in Australia alone.
The Future In Our Hands: Screening For Preclinical Alzheimer's Disease By Analysing Hand Movements
Funder

Funding Amount
$899,782.00
Summary
Alzheimer's disease (AD) starts damaging the brain 10-20 years before memory problems begin. By the time of diagnosis, it is hard to treat because the damage is so severe. We need a way to detect AD much earlier. We will develop a simple new computer test to detect early signs of AD by recording and analysing hand movements. Then people can start prevention earlier and scientists can research better treatments to improve people's quality of life and reduce the number of people with dementia.
Ataxia-Telangiectasia: An Emerging Role For Inflammation In Driving Neurodegeneration And Premature Ageing
Funder
National Health and Medical Research Council
Funding Amount
$437,436.00
Summary
Ataxia-Telangiectasia (A-T) is a devastating genetic disease that arises in early childhood and causes patients to die in their twenties. To date there is no cure, and therapeutics are desperately needed. This project will use state-of-the-art brain organoids derived from stem cells of A-T patients in order to better understand this disease and evaluate novel drugs that target the molecular mechanisms that drive chronic inflammation and brain neurodegeneration in children with A-T.
Finely Tuned Glutamate Receptor Inhibitors As Novel Therapeutics For Neurodegenerative Disorders
Funder
National Health and Medical Research Council
Funding Amount
$1,168,829.00
Summary
Neurodegenerative disorders are among the leading causes of death and disease burden. New drugs are needed to treat both symptoms and disease progression. This project aims to understand the properties of different drug-like compounds to inhibit proteins on the surface of brain cells (glutamate receptors) to impact disease progression and symptoms in a preclinical disease models. The project will yield a better understanding of how best to target glutamate receptors for therapeutic effect.
