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.

GABA(B) Receptor Modulation Of Gastrointestinal Function In Health And Disease By Alpha-Conotoxins

Funding Amount
$689,050.00
Summary
Chronic visceral pain is a common and debilitating condition arising from numerous diseases that affect our internal organs. There is a desperate need for more information about the mechanisms responsible for signalling chronic visceral pain to provide therapies and potentially find a cure for it. Our research focuses on ?-conotoxins (small peptides from marine cone snail venom) as novel potential therapeutic agents for the treatment of chronic visceral pain.
Cell Surface Mucins In Gastrointestinal Infection, Inflammation And Cancer Development

Funding Amount
$469,627.00
Summary
Cell surface mucins are protective molecules that line all the wet surface of the body, including the gastrointestinal tract. Our research has uncovered that mucins regulate cell growth and cell death. Inappropriate control by the mucins, could lead to chronic inflammation and formation of cancers. We will test how important these molecules are in the development of cancers in the intestine, and further explore the mechanism of action.
Deadly Commute - Targeting The Trafficking Mechanisms That Licence Inflammatory Cell Death

Summary
MLKL is a protein naturally found inside cells. MLKL is activated by inflammation. Once activated, MLKL relocates to the outer periphery of cells and kills them. Gut cells are especially vulnerable to death-by-MLKL and this problem causes Inflammatory Bowel Disease. Using cutting edge microscopy, we have discovered how MLKL moves to the periphery of cells prior to killing them. We will test if blocking this movement of MLKL to the cell periphery stops gut death and Inflammatory Bowel Disease.
Regulation Of NOD Signalling By IAPs And RIP Kinases

Funding Amount
$643,172.00
Summary
Alterations in NOD signalling have been implicated in various human inflammatory diseases, particularly in Crohn’s disease and asthma. In this project we will identify new molecules that regulate NOD signalling and test the effect of drugs that inhibit known components of these pathways to determine their utility in treating inflammatory diseases.
Host Cell Death Signaling And Susceptibility To Bacterial Gut Infection

National Health and Medical Research Council
Funding Amount
$682,321.00
Summary
Bacterial infections are a major cause of infectious disease worldwide. Here we aim to characterise immune responses that help fight infection by E. coli and Salmonella. These bacteria have evolved ways to shut down many of our immune responses during infection, allowing them to survive and cause disease. This work will help understand the complex relationship between gut bacteria and our immune system and provide solutions for controlling infection and treating immune disorders of the gut.
Chronic inflammation underlies common and debilitating diseases and causes pain by unknown mechanisms. There is an urgent need to gain a deeper understanding of the mechanisms of chronic pain, which will allow the development of improved therapies with fewer side-effects. Our research program investigates the mechanisms of pain that are associated with inflammatory bowel disease and irritable bowel syndrome, with the goal of developing more effective and selective therapies.
The Fetal And Early Childhood Origins Of PCOS: A Prospective Cohort Study

Summary
The Polycystic Ovary Syndrome (PCOS) affects up to 10% of women of reproductive age, which translates into around 350,000 women in Australia. It is the most common hormonal disorder in women. The syndrome has far-reaching adverse implications for general and reproductive health, including menstrual disorder, obesity, infertility, miscarriage, pregnancy complications, increased risk of diabetes and possibly heart disease. PCOS also commonly causes cosmetic problems such as excess body hair and ac ....The Polycystic Ovary Syndrome (PCOS) affects up to 10% of women of reproductive age, which translates into around 350,000 women in Australia. It is the most common hormonal disorder in women. The syndrome has far-reaching adverse implications for general and reproductive health, including menstrual disorder, obesity, infertility, miscarriage, pregnancy complications, increased risk of diabetes and possibly heart disease. PCOS also commonly causes cosmetic problems such as excess body hair and acne. The underlying causes of PCOS are not known but are thought to arise during intrauterine (fetal) life and to be modified by aspects of childhood health, particularly overweight and obesity. Using a large and well established cohort of adolescents followed up since fetal life and throughout childhood and currently aged 13-15 years old (the Raine cohort), we will define for the first time the intrauterine and early childhood correlates of PCOS. PCOS will be diagnosed by a specialist gynacologist using current international criteria. We will then utilise extensive existing data from this cohort combined with new measurements on existing samples to determine the contribution of key factors including fetal growth restriction, low birth weight, fetal androgen exposure, rapid postnatal growth, childhood adiposity, elevated fasting glucose and insulin and age at menarche to PCOS. In this way, we will address for the first time the hypothesis that PCOS arises as a result of events during fetal life and is affected by factors during childhood. The results from these studies will improve our understanding of PCOS and eventually improve reproductive and metabolic health for a substantial population of women internationally. It is essential that these studies are conducted as soon as possible or the opportunity will be missed. Girls with persistent menstrual irregularity are likely to be commenced on hormonal treatments which will make the diagnosis of PCOS impossible.Read moreRead less
Improving Physical Health Outcomes For Young People With Psychotic Disorders
Funder
National Health and Medical Research Council
Funding Amount
$189,384.00
Summary
Enduring psychotic disorders are associated with a reduced life expectancy by 25 years, which is mainly due to cardiovascular disease. This project will produce a training package that will improve clinician’s skills and knowledge of screening and treatment for physical health risk factors in young people with psychosis. This project will result in the development of an intervention for reducing the prevalence of these cardiovascular risk factors known to contribute to this early mortality.
