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.

Investigation Of Unique Immune Microenvironment Of Primary CNS Lymphoma
Funder
National Health and Medical Research Council
Funding Amount
$265,138.00
Summary
This study will investigate how the immune system responds to the development of brain lymphoma. It is expected that this lymphoma develops due to a defective immune response. It is unknown why the tumour is so effective at evading the immune response but if the hypothesis is correct, then the application of new drugs that stimulate the immune system to attack the lymphoma could lead to a marked improvement in survival without the need for toxic chemotherapy and radiation.
Investigating The Delivery Of Cytotoxic T Cell Lytic Granules And The Microenvironment Of The Immunological Synapse
Funder
National Health and Medical Research Council
Funding Amount
$355,169.00
Summary
T cells recognise infected or cancer cells and eliminate them from the body. They kill their targets by tightly attaching and releasing toxic proteins, which cause the target to undergo cell suicide. This research will use high resolution imaging to investigate the environment of the synapse between the two cells and understand parameters required for the delivery of a lethal hit. This will provide powerful insights into the working of the cell, and may identify novel intervention targets
The Differentiation And Function Of T Follicular Helper (TFH) Cells And Their Role In Autoimmunity
Funder
National Health and Medical Research Council
Funding Amount
$143,758.00
Summary
Antibody production is essential for immune responses and regulated by a subset of lymphocytes named T follicular helper (TFH) cells. Consequently, dysregulation of TFH cell function, or expression of TFH cell-associated molecules most likely contributes to the pathogenesis of certain autoimmune or immunodeficient diseases. Knowledge on TFH cells can greatly facilitate the development of new diagnosis and therapy.
Targeting An Epigenetic Silencing Pathway To Treat Allergic Asthma
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
Asthma affects around 11% of the Australian population and costs the health care system around $28 billion. Unfortunately there is still no cure and treatments have not changed for decades. This project aims to discover new drugs to treat asthma by re-wiring the cells of the immune system which cause the disease.
Structural And Functional Studies Of T-cell Mediated Recognition Of Microbial Lipids Presented By CD1c
Funder
National Health and Medical Research Council
Funding Amount
$316,449.00
Summary
The CD1c molecule plays an important role in the immune system by presenting lipid-based antigen of pathogens to the surface of an antigen presenting cell (APC) that is infected by the pathogen. Once a T cell receptor (TCR), which is expressed on the surface of a Killer T cell, recognises CD1c presenting pathogenic lipid, any infected cells will be destroyed. My research will look at the molecular mechanism of T cell recognising tuberculosis related lipids that is presented by CD1c.
Characterization Of H. Pylori –specific CD4 T Cell Responses And The Evaluation Of The Basic Requirements For The Development Of An Effective Anti-H. Pylori Vaccine
Funder
National Health and Medical Research Council
Funding Amount
$313,161.00
Summary
H. pylori infect over half of the global population. Although infection results in asymptomatic gastritis in most cases 10 % develop gastric ulcers and cancer. Current vaccination strategies have failed to protect humans from infection. We aim to characterise the main immune cells involved in H. pylori infection, specifically the bacteria-specific CD4 T cells. We will then try to understand the basic requirements for a successful vaccine in order to develop new, improved anti-H. pylori vaccines.
T-cells: The Key To Unlocking Immunity Against Aggressive Lymphoma
Funder
National Health and Medical Research Council
Funding Amount
$322,951.00
Summary
By investigating several aspects of patients’ immune defenses against the cancer cells in Diffuse large B-cell lymphoma, this project will provide critical insights on ways to harness the patient’s own immune system to effectively mount anti-tumour responses. These results will pave the way for future therapeutic strategies to successfully treat and prevent lymphoma.
