Summary
Kidney disease, including glomerulonephritis, is an important cause of ill-health in Australia. Some forms of kidney inflammation are linked to infection, but we don�t understand why. This project explores products from bacteria, particularly S.aureus, to work out how bacterial infection affects a form of kidney inflammation - ANCA-associated glomerulonephritis. It will establish how infection related signals activate local and immune cells, and define links between infection and the disease.
The Role Of Regulatory T Cells In Rapidly Progressive Glomerulonephritis

Summary
Inflammation of the kidneys is an important, yet poorly understood cause of kidney disease in Australia. As part of our endogenous defenses against inflammation, we have cells called regulatory T cells that dampen inflammation and are protective. This project will define the role of some of these cells and examine potential ways to use them do dampen kidney inflammation.

Summary
Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children. The majority of patients with CAKUT do not know the underlying cause of their renal anomalies. In this proposal we will characterise the developmental events that are perturbed in three mouse models of CAKUT and identify the causal gene responsible in each mouse model. We will translate this information to the clinic by screening patients with CAKUT for mutations in these newly identified ....Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children.

The Role Of IL-18 In Proliferative And Crescentic Glomerulonephritis

Summary
Inflammation of the small filters with the kidneys, known as glomerulonephritis, is the commonest cause of kidney failure in Australia. People whose kidneys have failed need either kidney dialysis or a kidney transplant. Our understanding of the immune events that cause glomerulonephritis is patchy. However, it is known that T cells are the directors of immune responses in the body and direct the immune response in glomerulonephritis. Chemical messengers known as cytokines direct the way T cells ....Inflammation of the small filters with the kidneys, known as glomerulonephritis, is the commonest cause of kidney failure in Australia. People whose kidneys have failed need either kidney dialysis or a kidney transplant. Our understanding of the immune events that cause glomerulonephritis is patchy. However, it is known that T cells are the directors of immune responses in the body and direct the immune response in glomerulonephritis. Chemical messengers known as cytokines direct the way T cells behave. One of these cytokines, known as interleukin-18, has been shown to stimulate T cells and other immune cells to induce inflammation that is helpful when the body is fighting infection but is harmful in immune diseases. This project will determine the role of interleukin-18 in glomerulonephritis by studying the way it talks to T cells and the mechanisms by which it incites inflammation in the kidney. Mice with glomerulonephritis will be treated by blocking the actions of interleukin-18 to discover whether interleukin-18 produced by the animal is important in kidney damage induced by glomerulonephritis, to understand the way in which this cytokine works and to assess whether blocking interleukin-18 could be a useful treatment for glomerulonephritis in humans. Current treatments for glomerulonephritis are often ineffective and have unwanted side effects. Knowledge of the way interleukin-18 participates in the immune response in glomerulonephritis may lead directly or indirectly to more effective and more targeted treatments for different forms of glomerulonephritis.Read moreRead less
Human Podocyte Depletion, Glomerular Hypertrophy And Glomerulosclerosis

Summary
Many kidney diseases commence with injury to glomeruli (kidney filters) which leads to glomerular scarring and loss. There is strong evidence from animal studies that a specific glomerular cell type (the podocyte) is central to this process of glomerular injury. In this study, we will analyse the relationships between podocyte depletion and glomerular scarring in human kidneys from 5 racial groups (white and African Americans, white and Aboriginal Australians, Senegalese Africans).
New Treatments For Acute Kidney Injury-Targeting The IL-17A Pathway

Summary
Acute kidney injury (AKI) is a common cause of ill-health and death. Despite the frequency and seriousness of AKI no new treatments have developed over the past 40 years. While AKI can occur spontaneously it can also develop after treatment with medications, in particular cancer therapies. In this proposal we will explore the effect of new treatments to prevent AKI. We plan to identify new treatments for patients with AKI, with particular relevance to patients receiving cancer treatments.
As women age, the quality of their eggs decline and their chance of having a healthy baby plummets. The accumulation of DNA damage within the egg, and the reduced ability to repair this damage, may be one cause of compromised reproductive success in older women. This project will investigate the ability of eggs to repair DNA damage during maternal aging and will explore the importance of DNA repair to fertility and the transmission of high quality genetic material to their offspring.
