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.

The development of vaccines and better treatments for HIV-AIDS and Hepatitis C are urgent global health priorities. This Program will undertake studies to better understand effective immunity against HIV and hepatitis C, allowing the rational design and testing of novel vaccines and treatments. The Program brings together a team of researchers with skills in basic virology and immunology with those providing expertise in translating findings in the laboratory into human clinical trials.
Role For Zinc And ZIP2 In The Action Of Nitric Oxide And In Vascular Protection Against Cigarette Smoke And Cardiovascular Disease
Funder
National Health and Medical Research Council
Funding Amount
$685,941.00
Summary
The NO/cGMP signalling pathway, which is central to cardiovascular physiology and protection against disease, is only fully effective when there are adequate levels of zinc in the vascular endothelium. This is especially important where zinc stores are depleted (elderly, smokers, diabetics and kidney disease). There is an urgent clinical need to implement strategies to monitor vascular Zn status. This application will explore the underlying science and translate these to the clinic.
Alveolar Macrophage Zinc And Zinc Transporters And Their Role In Phagocytosis
Funder
National Health and Medical Research Council
Funding Amount
$288,975.00
Summary
Zinc is an essential dietary component that serves a number of functions in the lungs. It is both an anti-oxidant and anti-inflammatory agent. Some airway inflammatory diseases such as emphysema may involve a critical loss of lung zinc. We believe that cigarette smoke causes the loss of zinc and this prevents the lung macrophages from working properly to clear bacteria and dead cells. This will provide a foundation for our long term goals of better clinical management of emphysema.
Airway Epithelial IAPs And Their Interaction With Zn Ions
Funder
National Health and Medical Research Council
Funding Amount
$260,779.00
Summary
The air we breathe contains a variety of harmful substances. Damage to the lining involves death of the ciliated cells that line the airways. We have shown that zinc protects these cells from premature death. This application focuses on a family of proteins called IAPs which bind zinc and regulate cell death in other tissues. This project focusses on how the IAPs and Zn may act together to mainitain healthy airways and how abnormalities of these may occur in people with asthma.
Role Of Zinc In The Respiratory Epithelium And Asthma

Funding Amount
$224,250.00
Summary
This project will use a panel of Zinquin-derived Zn fluorophores developed in our laboratory, as well as probes for the mammalian family of vesicular ZnT transporters, to carry out a study of the normal physiology of Zn in the respiratory system and potential abnormalities of this in patients with chronic inflammatory respiratory disease (asthma, COPD, chronic smoking). Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community. For example ....This project will use a panel of Zinquin-derived Zn fluorophores developed in our laboratory, as well as probes for the mammalian family of vesicular ZnT transporters, to carry out a study of the normal physiology of Zn in the respiratory system and potential abnormalities of this in patients with chronic inflammatory respiratory disease (asthma, COPD, chronic smoking). Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community. For example, asthma affects 12% of adults and amongst these, 15% waken weekly or more often with their asthma while 6% are hospitalized annually. There is a need to understand the basic mechanisms underlying these diseases so that new strategies can be developed to modify bronchocondtriction and inflammation. The project will provide new knowledge concerning the physiology of Zn in the respiratory epithelium and interactions between Zn deficiency and oxidants on injury in the respiratory tract. The usefulness of easily accessible nasal epithelial cells as a measure of Zn and Zn transporter levels deeper in the respiratory tract will be assessed. The project encompasses a number of fields and utilizes in vitro cellular and animal models, as well as tissues from human subjects.Read moreRead less
The Australian Centre For Research Excellence In Offender Health

Funding Amount
$2,646,826.00
Summary
Offenders are one of the most marginalised groups in society and endure the worst health outcomes in regards to mental health, exposure to bloodborne viruses and sexually transmissible infections, and engagement in health risk behaviours. Incarceration devastates Indigenous communities and we urgently need for solutions to reduce Aboriginal prisoner numbers. The research proposed by this CRE in mental health and infectious diseases will improve health outcomes for offenders and provide treatment ....Offenders are one of the most marginalised groups in society and endure the worst health outcomes in regards to mental health, exposure to bloodborne viruses and sexually transmissible infections, and engagement in health risk behaviours. Incarceration devastates Indigenous communities and we urgently need for solutions to reduce Aboriginal prisoner numbers. The research proposed by this CRE in mental health and infectious diseases will improve health outcomes for offenders and provide treatment solutions rather than incarceration.Read moreRead less
Inflammatory Cytokines As Causal Agents In Peri-conception Programming Of Offspring Health
Funder
National Health and Medical Research Council
Funding Amount
$604,046.00
Summary
Events at conception set the trajectory of fetal developmental that will determine health of children after birth and in later life. Susceptibility to obesity and metabolic conditions is established at this very early time. This project will define the molecular signals affecting the embryo in the event of maternal or paternal infection, diet and stress. The results will help us devise health advice for intending parents to improve child health and help prevent onset of metabolic disorders.
Molecular Profiling Of The Immunoglobulin Proteome In Primary Sjögren’s Syndrome
Funder
National Health and Medical Research Council
Funding Amount
$322,460.00
Summary
Primary Sjögren’s syndrome is a common autoimmune disease. The patients have high levels of circulating immunoglobulins (Igs) in their blood-a hallmark of the disorder. The applicant proposes to sequence these Igs and identify their so-called variable region molecular signatures. These signatures can then be used in a mass spectrometric-based diagnostic platform to identify unique clones in patients as early markers of the disease process, and hopefully lead to more relevant diagnostic markers.
Multistage Vaccines For The Prevention Of Tuberculosis
Funder
National Health and Medical Research Council
Funding Amount
$884,290.00
Summary
Almost two million people die from tuberculosis (TB) each year. The current vaccine, BCG, is ineffective at controlling TB and the type of immune response needed to protect against the disease is poorly understood. We have discovered new antigens of the TB bacterium, and we will combine them with novel delivery strategies to develop new TB vaccines. We will also determine the type of immune response needed to protect against TB, which will aid progression of vaccines into clinical trials.
The Male Partner Contribution To Pregnancy Immune Tolerance Deficit In Women
Funder
National Health and Medical Research Council
Funding Amount
$1,462,925.00
Summary
A complication-free pregnancy and birth of a healthy infant depends on adequate preparation of the mother's immune system to tolerate the 'foreign' fetus, Both the mother and the father contribute to establishing optimal immune tolerance. This project will determine the links between specific agents in male seminal fluid and the female immune response, and will make progress towards new diagnostic tests and treatment options for unexplained subfertility and gestational disorders.
