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.

EFFECTOR AND REGULATORY INTERSTITIAL INFLAMMATORY CELLS IN CHRONIC PROTEINURIC RENAL DISEASE

Summary
Current treatments for chronic kidney disease are ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year almost 1600 Australians commence dialysis for this reason, and many more die of kidney failure or its complications. This project will lead to a greater understanding of why kidney failure progresses, and will define more effective treatments for preventing progression. In progressive chronic kidney ....Current treatments for chronic kidney disease are ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year almost 1600 Australians commence dialysis for this reason, and many more die of kidney failure or its complications. This project will lead to a greater understanding of why kidney failure progresses, and will define more effective treatments for preventing progression. In progressive chronic kidney diseases of all types, the supporting tissue within the kidney (the interstitium) becomes infiltrated with inflammatory cells. The amount of interstitial inflammation has an important bearing on the severity of kidney failure, and the rate at which kidney disease progresses to endstage. The reasons that these inflammatory cells infiltrate the interstitium, and their exact role in the progression of kidney disease are only partially understood. For example, some of these inflammatory cells appear to cause kidney scarring, whereas others appear to be protective. Moreover, even though they are obvious targets for treatment aimed at slowing the progression of kidney disease, current treatments are largely ineffective as they do not differentiate between the different types of inflammatory cells, and whether these cells are causing or preventing damage. Our laboratory has recently developed a robust model of chronic kidney disease, which will be used to examine the effect of individual types of interstitial inflammatory cells on the progression of kidney disease. So far we have shown that depletion of one type of inflammatory cell (CD4 lymphocytes) worsened the disease process, whereas depletion of two other cell types (CD8 lymphocytes or macrophages) was protective. This raises the real and exciting possibility that treatment directed against specific inflammatory cells may be effective in the treatment of progressive kidney disease in humans.Read moreRead less
DNA Vaccination Using Chemokine And Costimulatory Pathways As A Treatment For Chronic Kidney Disease

Summary
Chronic kidney disease (CKD) is a great burden on Australia. Treatments are mostly ineffective. Our DNA vaccination against mediators of inflammation can protect against CKD. On the basis of ongoing studies we have identified 5 candidate molecules involved in recruitment and activation of inflammatory cells. We outline studies to generate DNA vaccines to these molecules, enhance their efficacy, and test them in models that represent the 3 most important causes of human CKD.
