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.
Enabling Evidence-informed Policy To Address Australia's Opioid Crisis

Funding Amount
$607,538.00
Summary
Australia has seen a near doubling of opioid-related mortality in the past decade. Recently, a range of state and national policy changes have been made to address the growing number of opioid-related deaths, yet the evidence for these kinds of policy changes is conflicting. This study will use prescribing data from general practice in combination with hospital data to understand the impact of three types of Australian policy interventions on opioid prescribing and opioid-related harm.
Neural Circuits Which Limit Alcohol And Soft Drink Intake

Funding Amount
$523,949.00
Summary
Alcohol and soft drinks are ubiquitous, and often harmful, particularly in excess. This project will examine the specific roles of fluid and food satiation neural circuits in suppressing intake, to determine whether either or both could be therapeutic targets for alcohol/soft drink overconsumption, especially as cessation aids for binge-drinking behaviour.
Intergenerational Impacts Of Paternal Immune Activation On Brain Function And Dysfunction

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

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.
Hybrid Optical-electrical Stimulation For Precise Neural Stimulation
Funder
National Health and Medical Research Council
Funding Amount
$935,579.00
Summary
In world-first research, we have evidence that combining electrical stimulation with optical stimulation significantly and safely improves precision of neural activation for devices such as cochlear and retinal implants. In this proposal we will use gene therapy to make nerves responsive to light in pre-clinical animal models to establish proof of concept that hybrid stimulation will significantly improve outcomes for recipients of cochlear and retinal implants.
