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.

Lymphoid Organ Development: Synthetic Organogenesis Of Artificial Spleen And Characterisation Of Tissue-specific Hematopoiesis

Funding Amount
$350,232.00
Summary
Spleen is an organ which filters blood circulating around the body and provides immune protection against blood-borne pathogens. Research into spleen development will attempt to synthesise artificial spleen tissue, leading to possible tissue replacement therapies or enhancement of immunity towards infection or cancer. Cellular development in spleen will also be investigated with a view to identifying novel white blood cell subsets that have potential for becoming new targets for immunotherapy.
Structure And Composition Of The Pre-T Cell Receptor-CD3 Complex

Summary
In order to recognize a wide variety of pathogens, humans produce many different T cell receptors (TCRs) by the process of gene-rearrangement. However, gene-rearrangement may not always lead to a functioning TCR. We are studying the pre-TCR protein that is responsible for monitoring the success of gene-rearrangement and is thus essential for the formation of a robust immune system. Understanding pre-TCR function will lead to new treatments for immune related diseases.
Investigating The Role Of TGF-beta In Resident Memory T Cell Induction And Maintenance

Summary
I am a research scientist interested in the immune system. Specifically, I intend to investigate immunological memory, which is the basis of vaccination. This refers to the ability of certain immune cells such as T and B cells to ‘remember’ a pathogen, so that a rapid and enhanced response can be generated upon re-infection with the same pathogen. This can be investigated by experimental techniques such as flow cytometry, histology and confocal microscopy on cells from infected mouse tissue.
The Role Of Mal In Toll-like Receptor Signal Transduction Of The Pro-inflammatory Response.

Summary
Sepsis kills more people per year than the cancers of the breast, colon, prostate and pancreas combined. Sepsis occurs in 1 of 50 hospital admissions and is the leading cause of death n intensive care units. The instance of sepsis has doubled in the last decade and is expected to increase. One of the major causes of sepsis si lipopolysaccharide (LPS), the main constituent of gram-negative bacteria's cell wall, and the prototypic inducer of the pro-inflammatory response of the innate immune syste ....Sepsis kills more people per year than the cancers of the breast, colon, prostate and pancreas combined. Sepsis occurs in 1 of 50 hospital admissions and is the leading cause of death n intensive care units. The instance of sepsis has doubled in the last decade and is expected to increase. One of the major causes of sepsis si lipopolysaccharide (LPS), the main constituent of gram-negative bacteria's cell wall, and the prototypic inducer of the pro-inflammatory response of the innate immune system. Dysregulation of the pro-inflammatory response can lead to sepsis. Recently, the mammalian receptor for LPS was found to be Toll-like receptor (TLR)-4, the activation of which activates a signal transduction pathway that initiates the pro-inflammatory response. We have previously shown a key role for an adapter protein called Mal in mediating signal transduction pathways upon activation of TLR-4. Interaction of Mal with a key signal transduction mediator called TRAF6 has been shown to induce the activation of the pro-inflammatory response. Furthermore, Mal has been found to undergo degradation which may indicate a means of regulating the continued activation of the pro-inflammatory pathway. This research program will investigate the role of Mal in mediating signal transduction in TLR activated macrophages, key responsive cells of the innate immune system to microbial infection. A greater understanding of these processes will assist in the development of therapeutics to alleviate the consequences of microbial-induced inflammation, including chronic inflammatory diseases and sepsis.Read moreRead less
