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 Regulators That Control The Pro-survival Molecule MCL1 And Its Stabililty In Lymphoma And Myeloma Cells

$169,162.00
Summary
B cell malignancies are common and in many cases result in mortality. The BCL-2 family protein MCL-1 has been shown to be over-expressed in many B cell malignancies. However, the regulation and biology of MCL-1 in these cancers remains largely unknown. We aim to define mechanisms that control regulation of MCL-1 expression in cancer cells at the transcriptional and protein level and hence identify new therapeutic targets.
Characterisation Of Autoreactive T Cells In Chronic Idiopathic Urticaria Would Improve Its Diagnosis And Treatment.

Summary
Chronic idiopathic urticaria (CIU) is a disease in which itchy hives recur due to no apparent trigger. It is an autoimmune disease in which the immune system reacts against certain cells in the skin, called mast cells and basophils. It is unclear how this occurs. Once activated, mast cells and basophils release a chemical called histamine, which is responsible for the rash. I aim to identify the immune reactions that occur in CIU, develop reliable tests for diagnosis and improve treatment of CIU ....Chronic idiopathic urticaria (CIU) is a disease in which itchy hives recur due to no apparent trigger.

The Regulation Of Monocyte Derived Dendritic Cells (moDCs) During Allograft Rejection

Summary
Islet transplantation can cure type 1 diabetes, but the required drugs for immunosuppressing graft rejection have side effects. Therefore understanding how immune rejection occurs so that we can suppress in a more discreet selective way is our goal. A type of cell that is prominent during graft rejection is the monocyte derived dendritic cell. We propose that this cell is critical for orchestrating immune responses during rejection. Therefore we wish to determine how such cells are controlled.
The Role Of Mucosal-associated Invariant T (MAIT) Cells And Gut Micro-biota In The Pathogenesis Of Paediatric Autoimmune Liver Disease (AILD).

Funding Amount

Summary
Liver disease can develop when a faulty immune system attacks the liver, occasionally leading to significant liver scarring and liver transplantation. Children who develop this condition need life-long treatment, but not every child responds. I intend to study immune cells and their activity in the blood and liver of affected children. By identifying the role of the immune system in liver inflammation, we hope to find out why children develop this disease and how best to treat them.
TOLL LIKE RECEPTORS AGGRAVATE GLOMERULONEPHRITIS AND KIDNEY INJURY IN RENAL VASCULITIS
Funder

Funding Amount
$110,068.00
Summary
Anti neutrophil cytoplasmic antibody associated vasculitis (AAV) is a significant cause of morbidity and mortality. My thesis will explore the role of Toll Like Receptor (TLR) 2 and TLR9 in the initiation and pathogenesis of AAV and the therapeutic potential of TLR2/9 inhibitors. I will use both a murine experimental model and human kidney biopsy samples in this work. My thesis will further define the critical molecular events that underlie the disease whilst addressing potential new therapies.
Understanding The Pathogenesis, Phenotypic Variation And Risk Prediction Of Childhood Asthma Using Computational Approaches
Funder

Funding Amount
$122,714.00
Summary
Asthma is a common respiratory illness in Australia. It is important to be able to predict who gets asthma, because those who get early treatment tend to fare better. We plan to run complex tests on data collected from hundreds of Australian children. The collected data includes genetic variations, chest infections, and differences in immune responses. From this data we hope to achieve a better understanding of the driving forces behind asthma, and to make better predictions for those at risk.
Identifying The Molecular Basis Of Memory B Cell Function And Human Immunoglobulin E Memory Via Hyper Immunoglobulin E Syndromes
Funder
National Health and Medical Research Council
Funding Amount
$96,009.00
Summary
Memory B cells generate rapid and potent antibody responses to known threats. The molecular basis for this is unknown, but defects increase the risk of infection, autoimmunity, and allergy. Autoimmunity and allergy are often mediated by a poorly understood antibody subclass, immunoglobulin E (IgE). My project will use emerging single-cell technologies to reveal the molecular mechanisms of antibody memory and IgE regulation, enabling the design of superior vaccines and immunomodulatory therapy.
Antibiotic Allergy Testing And Its Impact On Antimicrobial Stewardship In The Immunocompromised Host
Funder

Funding Amount
$124,714.00
Summary
While antibiotic allergy labels are common, the impact on immunosuppressed patients is unknown. This collaboration between Austin Health, Peter MacCallum Cancer Centre and Vanderbilt University Medical Centre (USA) will be the first Australian assessment of the impacts of antibiotic allergy labels on immunosuppressed patients. This project will provide strategies to examine the impact of and revise the antibiotic allergy labels with skin prick allergy testing and advanced immunodiagnostics.
The Role Of Th17 And Tregs In The Development Of Tolerance And Rejection In A Murine Model Of Renal Allograft Rejection
Funder

Funding Amount

Summary
In clinical transplantation, rejection remains the greatest problem in determining both short and long-term patient outcomes. Tolerance, the ability of the body to accept a transplant without immunosuppressive drugs, remains an as yet unattained goal. The aim of this project is to examine the mechanisms by which the initial immune response (innate immunity) affects the development of tolerance or rejection in a mouse model of kidney transplantation.
Inflammatory skin disorders, such as psoriasis and dermatitis, are responsible for a large burden of human disease and affect people across alldemographics. Knockout (KO) of TNF signalling members in mice is known to induce skin inflammation. This project proposes to use these genetic mouse models to investigate how and why disruption of particular TNF superfamily members leads to disease and potentially identify new targets for treatment.
