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.

SNARE-mediated perforin and cytokine release in natural killer cells. Cytotoxic cells release toxic granules and cytokine messengers to kill pathogen infected and cancerous cells and to mount immune responses. This project will investigate different SNARE molecules that regulate the secretion of perforin from granules and cytokines from other carriers, assisting in the understanding of complex but essential cellular pathways.
The aim of this proposal is to test the safety of a novel immunotherapy based on Helicobacter pylori platform technology to treat childhood allergies. Repeated oral administration of killed H. pylori mimics colonisation in the stomach and assists the development of a balanced immune system without the associated disease risk of live H. pylori. To achieve this goal Professor Barry Marshall has assembled a cross-disciplinary team of experts from Industry, Academia and Clinic.
Understanding and implications of formation of lipid nanostructures in milk. This project aims to deliver new understanding of the processes of milk digestion. Milk is the most important food for human survival, providing all the essential nutrition to newborn infants and constituting a major part of the adult diet. The recent discovery that nanostructure is formed during the digestion of both cow and breast milk, but not of vegetable 'milk', has opened a large number of questions to answer in t ....Understanding and implications of formation of lipid nanostructures in milk. This project aims to deliver new understanding of the processes of milk digestion. Milk is the most important food for human survival, providing all the essential nutrition to newborn infants and constituting a major part of the adult diet. The recent discovery that nanostructure is formed during the digestion of both cow and breast milk, but not of vegetable 'milk', has opened a large number of questions to answer in this project. Specifically, the project plans to link nanostructure formation in milk with composition during digestion, and the subsequent delivery of nutrients. The project plans to use synchrotron and microscopy techniques to address these questions. Project outcomes may improve our understanding of digestion and drive innovation in products delivering nutrients to infants.Read moreRead less
Nanostructured dairy powder for improved functionality. More than 30 per cent of the total milk produced in Australia is converted to powder for export. This project will lead to improvement in the solubility, and hence shelf-life, of protein rich dairy powders which will be of significant economic benefit to the industry. This project will also benefit the wider scientific community in dairy and food sectors.
Population Prevalence And Environmental-genetic Predictors Of Food Allergy In An Infant Cohort

Funding Amount

Summary
This study will measure which children are at greatest risk of food allergy. We plan to recruit 5000 children to test for food allergies, as well as asking a range of questions on different lifestyle factors such as diet and history of allergies . If positive, participants will be invited to a hospital clinic for tests and treatment. This will allow us to describe the epidemiology of food allergy, and assist the development of better services for those with food allergy in the community.
The molecular basis of macropinocytosis in mammalian cells: the composition of endosome proteins and their function. Individual cells communicate with their immediate environment by the process of macropinocytosis, a process that involves the exchange of materials between the extracellular space and a specialised region of the cell termed endosomes. It is an important process in mammalian cells being essential to the correct functioning of many tissues. This project will advance understanding of ....The molecular basis of macropinocytosis in mammalian cells: the composition of endosome proteins and their function. Individual cells communicate with their immediate environment by the process of macropinocytosis, a process that involves the exchange of materials between the extracellular space and a specialised region of the cell termed endosomes. It is an important process in mammalian cells being essential to the correct functioning of many tissues. This project will advance understanding of macropinocytosis at a molecular level. The project is relevant to understanding the functioning of normal cells and the means by which some pathogens can enter cells and also understanding processes involved in tumour progression and metastasis.Read moreRead less
Probiotic Prawn Oral Immunotherapy (ProPIT) For Treatment Of Prawn Allergy

Funding Amount
$1,865,369.00
Summary
A ‘curative’ food allergy treatment is needed to prevent deaths and improve care. We recently showed that probiotic peanut oral immunotherapy (PPOIT) was highly effective for treating peanut allergy. 82% of PPOIT treated children gained tolerance compared to 4% of the placebo group. We will now test the combined probiotic-food OIT approach for treating prawn allergy. If successful, we will have identified the first treatment for prawn allergy and a platform treatment for other food allergies.
Determination of the mechanisms of immune system regulation of inflammation by the human protein, chaperonin 10. The aim of this project is to determine the mechanisms by which a human protein, chaperonin 10 (Cpn10), regulates the immune system and suppresses inflammation. When cells of the human immune system are challenged with lipopolysaccharide (LPS) (a product of bacterial infection), the pro-inflammatory cytokine TNF is released. Cpn10 has been shown to suppress production of TNF on chall ....Determination of the mechanisms of immune system regulation of inflammation by the human protein, chaperonin 10. The aim of this project is to determine the mechanisms by which a human protein, chaperonin 10 (Cpn10), regulates the immune system and suppresses inflammation. When cells of the human immune system are challenged with lipopolysaccharide (LPS) (a product of bacterial infection), the pro-inflammatory cytokine TNF is released. Cpn10 has been shown to suppress production of TNF on challenge of cells with LPS, while increasing the levels of the anti-inflammatory cytokine IL-10. Investigating the role of Cpn10 in modulating inflammation will contribute to the understanding and treatment of diseases associated with inflammation, including multiple sclerosis and rheumatoid arthritis.Read moreRead less
Designing new generation adjuvants for allergy and parasite vaccines. Allergy vaccines have the potential to provide a permanent cure against many allergic diseases, currently affecting 20-30 per cent of people in developed countries. This project will study how allergy vaccines work and how we can improve their effectiveness and safety.
Centre Of Research Excellence In Eradicating Food Allergy: Prevention, Cure And Reducing Adverse Events

Funding Amount

Summary
Australia has the highest reported rate of food allergy in the world. We aim to eradicate food allergy through improved prevention and cure, supported by evidence generated by our collaborative network of research. In addition, we aim to help prevent children with food allergy having anaphylaxis through improved public health policy and clinical pathways. As a second wave of the allergy epidemic, we are well positioned to turn back the tide of this newly emergent health threat to the public.
