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.

The Identification Of Thoracic Targets For Prevention And Intervention In Bronchopulmonary Dysplasia
Funder

Funding Amount
$316,449.00
Summary
The persistence of breathing problems from infancy to later life is a complication of premature birth with lifelong consequences. Breathing problems often occur together with lung disease, but prematurity can also affect heart and blood vessel development, and weakness of the main breathing muscle. We will find out how much the heart, lungs and diaphragm contribute to breathing problems in babies; helping us to better predict, diagnose and treat severe breathing problems in babies born preterm.
Do Exposures Before Conception Influence The Risk Of Asthma In Offspring?
Funder
National Health and Medical Research Council
Funding Amount
$688,586.00
Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
DYRK1A As A Novel Target For Glioblastoma Therapies
Funder
National Health and Medical Research Council
Funding Amount
$620,294.00
Summary
Glioblastoma is a form of brain cancer that is currently incurable. We have discovered that switching-off an enzyme called DYRK1A (using ‘DYRK1A inhibitors’) kills glioblastoma cells. This therapeutic advantage is even greater when combined with drugs approved for other cancers. This project will develop new DYRK1A inhibitors and examine a novel combination treatment for glioblastoma patients. This could initiate a novel therapy that could significantly extend patients’ lives.
The health effects of electronic cigarette use are virtually unknown. They have only recently been introduced into widespread use, and as such their effects on human health will not be known for many years. We will use our expertise in exposure models and health outcome measurement to provide timely hard-data on their potential to impact health – data that are urgently required to guide policy makers in this area.
Exercise As Medicine For Heart Failure: A Novel Intervention To Improve Outcomes
Funder
National Health and Medical Research Council
Funding Amount
$665,585.00
Summary
Heart failure (HF) is a common, debilitating and expensive disease; prognosis remains poorer than for the most cancers. 30,000 Australians are diagnosed every year and 300,000 live with the HF, at an annual cost of ~$1Billion. Exercise training is effective therapy in HF, because it reverses many of the problems that contribute to the reduced lifespan and impaired quality of life of patients with HF. We will test an exciting new type of exercise that promising greater benefit, at lower risk.
Postviral Wheezing In Childhood: Disregulation Of Airway Tone?

Funding Amount
$577,040.00
Summary
Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. Ho ....Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. However, many infants who wheeze with viral infections, especially in the first year of life, do not develop allergies in later life, raising the possibility that they did not have the same type of asthma as those whose symptoms persist. This project will study the effects of viral infections on lung function to determine whether particular types of virus can have detrimental effects of lung function lasting for years. We will also examine whether the age at which the infection occurs and the severity of the infection influence the long-term outcome. The project involves studying infants during the recovery phase of respiratory viral infections, older children years after documented infections and experimental animal models that have been infected under controlled conditions. By determining whether respiratory viral infections can have long-term effects on lung function that can mimic asthma, we will advance our understanding of how asthma develops. In addition, specific treatment and preventative strategies could then be developed to prevent these long-term abnormalities, instead of relying on asthma medication (especially inhaled corticosteroids) as is the current practice. Preventative strategies could include encouraging the development of specific vaccines.Read moreRead less
Developmental Origins Of Adult Cardiovascular Disease: Vascular Health In The Raine Cohort
Funder
National Health and Medical Research Council
Funding Amount
$1,087,427.00
Summary
The Raine study is a unique long term experiment that has collected extensive pre-birth and childhood data in ~3000 young Australians, who are now 27 years old. We plan to measure the artery health of 1200 of these volunteers and to determine what factors, both before and after birth, influence the presence of early atherosclerosis in humans. This study will guide strategies aimed at early prevention of heart attacks and stroke in humans, by defining the major risk factors.
Antigen Selection In The MHC-restricted Cellular Immune Response

When microorganisms hide inside the cells of the body they are still detected by a set of T lymphocytes which have specific receptors for scrutinising the surface of cells for any changes which might signal an intracellular infection. The immune system is ever vigilant in its search for signs of infection which are generally apparent when molecules called antigens are released by microorganisms and captured by the body's cells. This activates lymphocytes resulting in an immune response capable of eliminating the microorganisms. Scrutiny of the body's cells by lymphocytes occurs continuously even when there is no infection present in the body. Following infection of a cell, microbial antigens reveal the infection by their appearance on the cell surface where they are detected by the immune system's lymphocytes. This occurs through a mechanism called antigen presentation. During antigen presentation the proteins inside the cell, including those of any invading microorganism, are first degraded into shorter molecules called peptides. This event is called antigen processing. A fraction of the peptides created by antigen processing are captured by specialised receptors present on all cells. These receptors are called HLA or histocompatibility molecules. This project examines the molecular events which mediate the capture of peptide antigens by HLA molecules. The main focus is on those peptide antigens which elicit killer T cell responses by the immune system. A knowledge of how these peptides are selected for presentation and how they are captured and carried to the cell surface is fundamental to understanding immune responses to microorganisms, tumours, allergens, transplants and self tissues as in autoimmunity. Therefore the study is of great general relevance.Read moreRead less
