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.

Macfarlane Adaptive Changes In HIV-1 Subtype C Envelope Glycoproteins Contributing To Pathogenicity.

Summary
HIV exists as multiple subtypes. The most commonly studied is type B (B-HIV). B-HIV is common in developed countries, but accounts for only a small fraction of HIV infections worldwide. Type C HIV (C-HIV) in Africa and Asia accounts for the majority of infections worldwide, yet very little is known about how C-HIV causes AIDS. We aim to understand how C-HIV causes AIDS. This is critical for development of drugs and vaccines specifically designed for those who are most urgently need.
Genomic Analysis Of Host Response To Influenza A Infection

Funding Amount
$168,530.00
Summary
Influenza virus infects millions of people globally. However, it remains poorly understood why some infected individuals succumb to life threatening complications whilst others recovered relatively unaffected. This study use advance molecular technique to study influenza infection. It aims to identify the key steps in our immune systems that are progressively disrupted during influenza infection and how this process lead to a break down in our natural defence against the virus.
Dissecting Mechanisms Of Generalised Immune Activation And Cellular Dysfunction In HIV Infection

Funding Amount
$422,576.00
Summary
How HIV infection compromises the host immune system is still not well understood. We will study how HIV surface proteins contribute to heightened immune activation during chronic infection. This generalised activation eventually leads to dysfunctional cellular immune responses and loss of partial control of infection. We will additionally investigate the extent and impact of the loss of functional immune responses in chronic HIV infection.
The Genetics And Mechanisms Of Resistance To The Zoonotic Highly Pathogenic Influenza Virus In Avian Species

Funding Amount
$337,373.00
Summary
Highly pathogenic avian influenza (HPAI) poses a serious pandemic risk. This project will investigate the genetic basis and mechanisms underlying resistance to HPAI in birds. It will explore the role of immune genes in resistance to HPAI in six bird species which vary in their susceptibility to HPAI. Functional tests of resistance genes will be performed to determine how these genes can provide resistance to HPAI. This study will assist in the development of strategies to mitigate disease risks.
Immunological Changes During Pregnancy And The Impact On Viral Hepatitis Infection
Funder

Funding Amount
$353,355.00
Summary
Hepatitis B virus (HBV) can cause long term health problems particularly affecting the liver and can be passed from mother to baby. Despite the availability of a HBV vaccine babies can still become infected. During pregnancy there are changes in a woman’s immune system which may impact on HBV infection and make transmission to the baby more likely. This research aims to explore the changes in a woman’s immune system and the impact this has on risks for hepatitis and transmission to the baby.
Dissecting The Mechanisms Of Vaccine Immunogenicity And Induction Of Protective Immunity Against Influenza Virus
Funder
National Health and Medical Research Council
Funding Amount
$365,145.00
Summary
Influenza pandemics have historically led to worldwide morbidity and mortality. Vaccination remains to be the only plausible strategy to limit widespread mortality as a result of an influenza pandemic. The parts of the immune system important in protecting individuals from influenza virus are poorly understood. This research aims to understand the important correlates of protective immunity in order to improve vaccine design.
