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 Role Of CD1-restricted T Cells In Health And Disease
Funder
National Health and Medical Research Council
Funding Amount
$431,000.00
Summary
The human immune system requires T cells for survival. Specialised populations of T cells exist that patrol the body and target unwanted lipid molecules expressed by bacteria or by cells that have become abnormal or cancerous. I will identify these T cells in human blood and skin and determine their role in protection against disease. I will explore the types of lipids molecules recognised by these T cells and use this information to help prevent human diseases.
Defining The Coordination Of Immune Responses To Pathogens
Funder
National Health and Medical Research Council
Funding Amount
$640,210.00
Summary
Understanding how immune responses are coordinated is critical for the design of new therapies and vaccines to target infectious diseases and cancers. This project will utilise advanced imaging combined with novel tools to dissect the complex interactions that occur between immune cells as they are activated and patrol the body to eliminate infectious pathogens.
Using Single-cell Genomics To Resolve Functional Diversification By CD4+ T Cells In Vivo
Funder
National Health and Medical Research Council
Funding Amount
$1,048,096.00
Summary
During immune responses, individual CD4+ T cells multiply and produce hundreds of descendants, with close relatives within a family often developing very different skills. How such differences emerge from one ancestor remains unclear. We use new methods to look at individual CD4+ T cells in unprecedented detail, allowing us to see how close relatives begin to grow apart. Using this, we hope to find novel ways of educating CD4+ T cells to prevent infectious and immune-mediated diseases.
Dendritic Cell-mediated Induction Of T Cell Tolerance
Funder
National Health and Medical Research Council
Funding Amount
$654,725.00
Summary
Australia has some of the highest rates of immune-mediated diseases in the world. These diseases include autoimmune, allergic and inflammatory conditions. We will use a mouse model to study how dendritic cells can prevent the onset of these conditions by inactivating the immune cells that cause them. Our findings will aid in understanding why these diseases develop and how they may be prevented and treated.
Regulation Of T Cell Effector Function In Peripheral Tissues
Funder
National Health and Medical Research Council
Funding Amount
$698,550.00
Summary
Protection from infections relies on different types of immune cells. While some of these cells are found in the blood, others reside in peripheral tissues such as the skin. We will analyse the function of these peripheral immune cells to understand how they work to fight off infections. We will also investigate how so-called memory cells that permanently reside in peripheral tissues can protect from re-infection with similar bacteria or viruses.
The Mezzanine T Cell Response: Intervening At The Coal Face
Funder
National Health and Medical Research Council
Funding Amount
$765,585.00
Summary
In an initial immune response, specialised cells in lymph nodes tell T cells to multiply; the stimulated T cells depart and enter target tissue (e.g. lung in the case of flu). We describe a new response whereby the target tissue itself can tell T cells to multiply further. This response in target tissues reveals a new way of altering immune responses. This is especially important as in many diseases, the primary lymph node response has already occurred, so cannot be therapeutically intervened.
Investigating B Cell Development, Maintenance And High-affinity Antibody Production By ENU Mutagenesis
Funder
National Health and Medical Research Council
Funding Amount
$408,388.00
Summary
B cells are essential for the protection against infections. This application aims to identify new genes that are crucial for the development or function of B cells and will investigate how mutations in newly discovered genes contribute to defects in the development and function of B cells and the pathogenesis of B cell leukaemia.
The Structure And Composition Of The T-cell Receptor-CD3 Complex
Funder
National Health and Medical Research Council
Funding Amount
$434,644.00
Summary
Our research will provide a fundamental advance in our understanding of how foreign viruses and pathogens trigger the immune system. Gaining a greater understanding of these central events will facilitate the design of novel therapies to treat immune associated disorders such as transplant rejection, autoimmune disease and some cancers.
The Structure And Composition Of The T-Cell Receptor-CD3 Complex
Funder
National Health and Medical Research Council
Funding Amount
$419,180.00
Summary
My research will use cutting edge imaging techniques to provide a fundamental advance in our understanding of how foreign viruses and pathogens trigger the immune system. Gaining a greater understanding of these central events will facilitate the design of novel therapies to treat immune associated disorders such as transplant rejection, autoimmune disease and some cancers.
Studies On The Role Of The P101 Component Of The Class 1B PI 3-Kinase In Cell Migration And Activation.
Funder
National Health and Medical Research Council
Funding Amount
$457,267.00
Summary
This research will determine the biological role of a protein of unknown function that is likely to participate in movement of white blood cells through the body. The outcome of this research will increase our basic knowledge of how the immune system functions and could lead to alternate therapeutic strategies for the control of autoimmune diseases.
