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.

Understanding The Role Of NS Segments In Evading Influenza A Virus-specific Humoral And T Cell Immunity
Funder

Funding Amount
$213,812.00
Summary
Influenza viruses developed two ways to survive against host immune response: (i) mutating in its genes to escape host immune response, which may cause a new pandemic; (ii) using its NS1 protein to impair host immune response. However, little is known on how these two processes occur and whether NS1 could influence the outcome of escape mutants. By using virological and immunological methods, this study will show how viruses use different NS1 to enhance the viral escape mechanism.
Recognition And Interaction Of Virus By The Innate Immune System

Funding Amount
$307,946.00
Summary
The innate immune system acts rapidly to limit infection of invading pathogens. The interaction and recognition of pathogens such as viruses by the innate immune system, is of importance to understand why particular pathogens induce disease.
Molecular Characterisation Of Host Cell Targets Of Human Pathogenic Viruses And Evaluating Their Potential As Novel Therapeutic Targets.

Summary
There are currently no therapeutics to treat victims of Hendra, Nipah or Rabies virus infections, which account for > 50,000 deaths/yr worldwide. Through not fully understood mechanisms, these viruses affect the functions of specific cellular proteins in order to inhibit the host immune system, a process essential to their pathogenicity. We aim to characterise the mechanisms underlying viral inhibition of host immunity and evaluate their potential as novel targets to develop urgently needed t ....There are currently no therapeutics to treat victims of Hendra, Nipah or Rabies virus infections, which account for > 50,000 deaths/yr worldwide.

Bacterial Activation Of Epithelial Barrier Function
Funder
National Health and Medical Research Council
Funding Amount
$341,953.00
Summary
This project deals with a bacterium that is a major cause of hospital-acquired infections and is the main cause of disease for people with cystic fibrosis. The project aims to identify the cell components that are actively involved in signalling a bacterial infection in the lung and how the body adapts to this interaction. This work will allow us to better understand the biology of the lung and how it copes with infection and may lead to the development of new antibiotics.
Immunomodulatory Molecules Of Parasitic Helminths As Novel Therapeutics For Allergic Disorders.
Funder
National Health and Medical Research Council
Funding Amount
$321,532.00
Summary
Australia has one of the highest rates of asthma in the world with almost 3 million Australians are affected by this disease. Previous research has shown that infection with various types of parasitic worms lessens the severity of asthma. The aim of this research is to find out why this happens and to isolate the ingredients from the parasite that suppress asthma. Once found, these molecules can be used to create new drugs for the prevention of asthma and allergies in children and adults.
The Host Response To Highly Pathogenic Influenza Virus
Funder
National Health and Medical Research Council
Funding Amount
$237,981.00
Summary
Highly pathogenic influenza infections are a global health concern and cause global panic. There is no effective therapy available; for example and the death rate for H5N1 infection is ~60%. Here we propose to further understand host lung response to highly pathogenic influenza with a view to develop new therapies for this urgent issue.
The Role Of MHC In Immune Evasion: Insights From A Contagious Cancer
Funder
National Health and Medical Research Council
Funding Amount
$260,677.00
Summary
An aggressive, contagious cancer, Devil Facial Tumour Disease (DFTD), has emerged in the Tasmanian devil population. We are using the devil tumour to study how cancer is recognized by the immune system and ways in which cancer can 'escape' from the immune system. This research will contribute to our understanding of human cancer and help save an iconic Australian species from extinction.
Optimising Large-scale Public Health Interventions To Control Neglected Tropical Diseases
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
Neglected tropical diseases (NTD) are a group of health conditions that affect the poorest of the poor, particularly in remote and rural areas. They affect the most vulnerable communities and cause substantial, chronic health harms impairing personal and social development. Several debilitating NTD are common in remote indigenous communities and Pacific islands. I propose a series of studies to investigate new strategies to control NTD in large populations where these diseases are endemic.
