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.

Gamma-Delta Tregs, CD8 Tregs And Selected Natural Tregs To Treat Renal Injury

Summary
Chronic kidney disease (CKD) progresses due to ongoing damage to the kidney. We have identified three types of white cells that can reduce kidney damage in CKD. The first is a unique set of gamma-delta T cells that expand in the kidney and protect against injury. The second is a restricted set of CD8 T cell that can protect against kidney injury. The third are targeted natural regulatory T cells. These studies develop each of these three subsets as potential cellular therapies in CKD.
Costimulation In Progressive Non-immune Tubulointerstitial Renal Disease.

Summary
Current treatments for chronic kidney disease are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year about 1700 Australians commence dialysis for this reason and many more die of kidney failure or its complications. This project will examine the role of costimulatory molecules in causing chronic kidney disease (CRD) to progress and their potential as targets for specific ....Current treatments for chronic kidney disease are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year about 1700 Australians commence dialysis for this reason and many more die of kidney failure or its complications. This project will examine the role of costimulatory molecules in causing chronic kidney disease (CRD) to progress and their potential as targets for specific therapy to slow the progression of CRD. In chronic kidney diseases of all types, the kidney becomes infiltrated with inflammatory cells. The amount of inflammation has an important bearing on the severity of kidney failure and the rate at which kidney disease progresses. There are a range of different cells that invade the inflamed kidney, some may worsen disease while some may protect against it. Current treatments are non-selective and may, by suppressing inflammation, prevent both repair and protection. Costimulatory molecules have been shown to be important in the regulation of inflammatory cell activation in transplantation and some autoimmune diseases. We, and others, have evidence to suggest that costimulatory molecules may be pivotal to the development and progression of kidney inflammation in CRD as well. This project will use two robust animal models of human CRD to define the role of costimulatory molecules in progression of kidney disease. If, as our preliminary evidence suggests, costimulatory molecules are shown to alter disease progression, then they will provide excellent targets for new treatments. Eventually, treatment directed against costimulatory molecules may be used as more effective and safer therapy for human kidney disease.Read moreRead less

Summary
Chronic kidney disease (CKD) is a major cause of death and disability in the Australian population. Current treatments for CKD are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or tranplantation to remain alive.

Current treatments for CKD are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or tranplantation to remain alive. Every year more than 1700 Australians require kidney replacement therapy for this reason and many more die of kidney failure or its complications. Some forms of kidney disease are self-limited whereas others are characterised by chronic kidney scarring and the eventual development of endstage disease. This project will explore whether natural protective cells (regulatory T cells) can be used to treat differing types of CKD, including those characterised predominantly by inflammation or by fibrosis. In addition, the protective mechanisms of regulatory T cells (including their interaction with resident kidney cells) will be explored, as will ways of increasing the efficacy of regulatory T cell therapy.Read moreRead less
