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.

Immune Recognition Of Upper Airway Microbiota In Early Life As A Determinant Of Respiratory Health In Children
Funder
National Health and Medical Research Council
Funding Amount
$1,135,837.00
Summary
The study will investigate the impact of respiratory infections during infancy on lung & immune function & respiratory health between 3-7 years of age. Children were previously enrolled in a population based birth cohort study (ORChID study) which collected detailed information about the respiratory health during the first 2 years of life with daily respiratory diary & weekly nasal swab collection. In this study lung function & immune function will be assessed annually in the same children (3-7)
The Emerging Problem Of Non-tuberculous Mycobacteria Infection: Understanding Aetiology, Geospatial Epidemiology And Developing Interventions
Funder
National Health and Medical Research Council
Funding Amount
$988,791.00
Summary
This project will be largest study of non-tuberculous mycobacterial (NTM) infection in cystic fibrosis. By combining growing the bacteria with detailed information from the CF patient data registry, geographical location and environmental conditions, this study will provide novel insights into factors associated with NTM. Gene sequencing and airway infection profiling will extend understanding and has the potential to identify novel risk factors and biomarkers for NTM-related airways disease.
Targeting Translational Control By Modulating MiRNA Function As A Novel Way To Treat Respiratory Infections And Inflammatory Disease
Funder
National Health and Medical Research Council
Funding Amount
$700,623.00
Summary
Among the major health issues of today is our inability to effectively treat bacterial infections and the emergence of antibiotic resistant microbes. MicroRNA are small molecules that control the levels of proteins in immune cells that fight infections. In this project we will determine if inhibiting miRNA function in the lung enhances defence against microbial invasion and is a new therapeutic approach to treat infection driven diseases of the airways such asthma and emphysema.
Elucidating The Mechanisms Of Infection-induced, Steroid-resistant Asthma

Summary
Steroid-resistant asthma is an important clinical problem and effective therapies are urgently required. Substantial evidence links bacterial and viral respiratory infections with steroid-resistant asthma, however, how infections are associated with steroid-resistant asthma is not known. This project will investigate the role of specific immune factors, that we have identified, in infection-induced steroid-resistant asthma. Our project may identify new therapeutic targets for this severe form of ....Steroid-resistant asthma is an important clinical problem and effective therapies are urgently required.

Enhancing Innate Immune Responses To Influenza In Chronic Obstructive Pulmonary Disease

Funding Amount
$522,323.00
Summary
Infection with influenza is a serious health problem for all, but particularly those with chronic lung diseases such as chronic obstructive pulmonary disease (COPD). Current treatments are limited. We have previously shown that human COPD airway cells are more susceptible to infection with influenza and the virus is able to effectively block the early immune response. We propose to define the mechanism that underlie this and design novel inhibitors to enhance the early immune response of these c ....Infection with influenza is a serious health problem for all, but particularly those with chronic lung diseases such as chronic obstructive pulmonary disease (COPD). Current treatments are limited. We have previously shown that human COPD airway cells are more susceptible to infection with influenza and the virus is able to effectively block the early immune response. We propose to define the mechanism that underlie this and design novel inhibitors to enhance the early immune response of these cells and reduce the effects of infection.Read moreRead less
Understanding The Role Of Th22 Cells In Regulating Respiratory Immune Responses In Health And Disease.
Funder
National Health and Medical Research Council
Funding Amount
$870,476.00
Summary
T cells that produce the cytokine IL-22 (Th22 cells) are found in infectious and inflammatory lung disease. However, the role of Th22 cells in promoting or preventing disease remains largely unknown. We have discovered how to grow Th22 cells and have generated a unique strain of IL-22 reporter mice, which will allow us to identify their role in infectious and inflammatory diseases. Our investigations will provide new insights into therapeutic approaches for these diseases of the lung.
Characterising The Pro-inflammatory Role Of IL-36γ/IL-36R In Pathogen-induced Exacerbations Of Asthma And COPD
Funder
National Health and Medical Research Council
Funding Amount
$738,768.00
Summary
Lung infections cause exacerbations in patients with asthma and COPD and these are difficult to treat and can be life-threatening. We have discovered that the cytokine pathway, IL-36?/IL-36R, is linked to the host response to bacterial and viral infections that induce exacerbations in these patients. Our studies will provide new insight into the role IL-36?/IL-36R in infection, disease exacerbation and determine the therapeutic benefit of blocking this pathway.
Exploring The Role Of Respiratory Virus Infections In Childhood Asthma Exacerbations
Funder
National Health and Medical Research Council
Funding Amount
$596,649.00
Summary
The PEAK study will explore the reasons children get worse asthma symptoms when they get colds. These reasons examined include the asthma medications taken (or not taken), allergies and exposure to allergens and the type of virus involved. The study follows the children over the whole school term and uses a new way to sample virus by collecting it in the breath, this is more comfortable than old methods and can be done at home.
