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.

Suppressor Of Cytokine Signalling (SOCS4) Is A Critical Regulator Of The Anti-viral Immune Response

Summary
The SOCS proteins are negative regulators of cytokine signalling and immune cell development and function. SOCS4 is the last remaining SOCS protein for which there is no described function or intracellular target. We intend to use well-defined acute and chronic viral disease models, and investigate the role of SOCS4 in infection in order to unravel its function. We will also search for its binding partners and intracellular targets, and determine the signalling pathways regulated by SOCS4.
The immune system must be tightly regulated to make sure that it makes the right response to effectively fight off infection whilst avoiding inappropriate responses that cause damage such as in autoimmunity, inflammation or allergy. This project studies patients who have genetic defects that affect their immune systems and make them susceptible to infection and/or harmful immune responses. This will reveal some of the critical signals that maintain immune control.
Cytokine Signalling And The Regulation Of Normal And Leukaemic Blood Cells

Funding Amount

Summary
The formation and actions of white blood cells are regulated by protein messengers called cytokines. Cytokines deliver their message by inducing the activation of signalling pathways that orchestrate the cell’s response to infection but when these responses occur too robustly or at inappropriate times they can lead to autoimmune disease, tissue damage and blood cancers. We study the naturally occurring feedback inhibitors of these processes in order to devise new treatments for these diseases.
Exploring And Targeting The Anti-Inflammatory Signalling Mechanisms Of Interleukin 37

Funding Amount

Summary
Cytokines are messenger proteins that function as master regulators of biological processes; thus they play central roles in many diseases. The rare cytokines that block inflammation do so by dampening the immune system’s potentially destructive force, making them attractive targets for drug development. We showed that interleukin 37 is a powerful anti-inflammatory cytokine, and will now evaluate its mechanisms of action and its efficacy against several severe diseases, including cancer.
The immune system usually rapidly responds to eradicate infectious pathogens. However patients with mutations in the gene PI3KCD, which is important for delivering messages within immune cells, are unable to control infections with some bacteria and viruses. We will study the effects of these mutations on B cells, the immune cells produce antibodies that bind to and remove pathogens from our body. This will explain some of the clinical features of this disease and reveal potential new treatments
Unravelling How Protein Signalling Networks Integrate To Control T Cell Fate

Funding Amount
$408,768.00
Summary
Rational design of drug combinations to manipulate the immune response requires an understanding of how different signals work together to control cell behaviour. The PIM kinase proteins are known to regulate important properties of immune cells, including division and death and when dysregulated can lead to cancer. I will perform a comprehensive, unbiased investigation of how the PIM kinases interact with other protein signalling pathways to control the immune response in health and disease.
The Mechanism And Application Of A Superagonistic Antibody For Human IL-21.

Funding Amount
$95,313.00
Summary
Monoclonal antibodies are widely used in diagnosis and therapy due to their outstanding specificity and safety. The monoclonal antibodies recognizing cytokines with enhancing functions are an emerging class of novel reagents in immunotherapy. This project is to investigate how a newly indentified monoclonal antibody enhances the activity of a cytokine and use this immunostimulatory function to design new strategies for better vaccination and treatment for cancer and infection.
