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.

Functional Roles Of The Tegument Proteins Of Herpes Simplex Virus Type 1

Funding Amount
$461,597.00
Summary
The occurrence of herpes simplex virus (HSV) in the general population is very high (up to 60%). HSV enters the human body via the skin before entering nerve cells where it lies dormant in most people. Intermittently the virus reactivates and usually forms blisters at the skin when it sheds. The aim of this project is to define a molecular interaction network at the protein level during the course of infection of a host cell. This information will provide new targets for design of antivirals.
Understanding The Role Of Ongoing Viral Activity In Herpes Simplex Virus Latency

Funding Amount
$980,762.00
Summary
The virus that causes cold sores and genital herpes has a dormant phase from which renewed infection can recur. We recently discovered that this dormant phase is more active than we thought and we now want to learn how the body acts to suppress the virus so that these defence mechanisms might be improved to stop recurrent infections.
The Role Of Varicella Zoster Virus In Modulating Cutaneous Infection

Funding Amount
$555,892.00
Summary
Varicella zoster virus (VZV) causes two skin diseases: chickenpox and shingles. VZV can causes significant morbidity in children and adults and life-threatening disease in immunocompromised people. This project aims to improve our understanding of how VZV affects the function of specialised skin cells to provide information for the development of a better vaccine to lessen the impact of VZV disease on the community.
Role Of Toll-like Receptor 7 In Rhinovirus-induced Asthma Exacerbation

Summary
One third of the annual asthma-related health care expenditure may be attributable to asthma-related hospitalisations. Even mild asthmatics experience severe exacerbations at a rate of almost one per year1 and those attacks can be fatal. Rhinovirus (RV) causes the majority of asthma exacerbations which may be linked to an impaired antiviral interferon (IFN) response in asthmatics. RV is sensed by Toll-like receptor (TLR) 7, but the role of this innate host defence pathway in regulating antiviral
Asthma causes wheeze and shortness of breath via airway narrowing, with asthma attacks commonly caused by virus infections. We plan to investigate how airway narrowing during an asthma attack decreases the body’s ability to fight off a viral infection, causing prolonged infection, worse asthma symptoms, more airway inflammation and long-term damage within the airways. We will attempt to use current and novel treatments to reverse these problems, and improve treatment for asthma.
Effect Of Anti-IgE Antibody On Immune System Responses And Short-term Outcome In Acute Asthma In Children
Funder

Funding Amount
$571,752.00
Summary
We plan to undertake a randomised, double-blind, placebo-controlled, clinical trial of anti-IgE antibody given at the time of an acute attack of asthma in children aged 6-12 years. The idea for this arose from our own novel data – IgE levels increase with the most common infection causing acute asthma. Given evidence the virus uses IgE to cause inflammation, giving anti-IgE during the attack should reduce the severity of the attack and produce a new, effective treatment for acute asthma.
Identifying The Microbiological Risk Factors For Acute Lower Respiratory Infection In Indigenous Children To Inform Future Intervention Strategies
Funder
National Health and Medical Research Council
Funding Amount
$495,745.00
Summary
Lung infections such as pneumonia are common in Indigenous children, and can lead to repeated hospitalisation and permanent lung damage. They are also an important cause of preventable death in children. This study will look at the role of bacteria and viruses in lung infections, and will inform interventions to reduce the burden and consequences of lung infections in Indigenous children.
Exploring The Haemagglutinin-neuraminidase Of Human Parainfluenza Virus
Funder
National Health and Medical Research Council
Funding Amount
$731,268.00
Summary
Respiratory diseases, for example croup, in children are caused in the main by human parainfluenza viruses (hPIVs). No vaccines or specific antiviral therapy against hPIV infections exist. This project targets an essential protein in the virus’ lifecycle. This project will produce compounds that block the protein’s function and may provide drug candidates for development. Furthermore the role of human host cell-associated carbohydrates in parainfluenza infection will be better understood.
Protective memory T cell immune responses defend our body against pathogens by the rapid induction of killer T cells. This protects us from severe or perhaps even fatal disease. Our work will provide insights to how the body makes these potent ‘footsoldiers’. This work will have important implications for identifying how these immune cells can be manipulated to prevent and treat pathogenic and autoimmune disease and for optimising approaches to vaccination.
Rhinovirus Protease Subcellular Trafficking And Host Cell Targets; Relevance To Asthma Exacerbation And Vaccine Approaches
Funder

Funding Amount
$582,072.00
Summary
Rhinovirus (RV) infections are the major cause of virus induced asthma attacks, causing significant morbidity and mortality. Asthma & asthma exacerbations are increasing worldwide with new strategies urgently needed to reduce RV-associated disease. We aim to build on our substantive new data, using cutting edge technology to identify new targets for novel asthma therapies.
