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.
Pathogenic Dendritic Cells In Human Kidney Disease

Summary
The cost of treating end stage kidney disease in Australia is more than a billion dollars per year. Kidney disease is associated with an influx of inflammatory cells. However, current therapeutics fail to target this process due to our poor understanding of inflammatory immune cells in disease progression. This project will investigate the biology of immune cells in human kidney disease. I believe that this study will inform more accurate diagnoses and improved treatments for patients.
Developing Novel Therapeutic Approaches To Treat Chronic Kidney Disease

Summary
Progression of chronic kidney disease (CKD) to endstage is characterised by inflammation and fibrosis. No current treatment effectively halts CKD progression. We are using protective immune cells to treat CKD and have invented a genetically-engineered immune cell which uses damaging inflammatory signals to switch them into protective cells which reverse inflammation and fibrosis where they occur, to prevent progression of CKD and other diseases, such as those of heart, lung and liver.
Optimising The Therapeutic Efficacy Of Anti-inflammatory Macrophages For Use In Chronic Kidney Diseases

Summary
Chronic kidney disease (CKD) is a major cause of death and morbidity in Australia. Current treatments that are able to delay progression for CKD are limited. As a consequence, more than 2300 additional Australians need kidney replacement each year and many more die of kidney failure. We have reduced and prevented injury in a mouse model of CKD by administering protective white blood cells - macrophages. This project will modify macrophages ex vivo to optimize them for use as a therapy for CKD.
Conventional And Unconventional T Cells In Interstitial Kidney Disease

Summary
Acute damage to the kidney is a common life-threatening condition. Recent studies have shown that less well-studied types of immune cells contribute to kidney damage. However, how these cells enter and injure the kidney is unknown. In this project we will use a special microscope to look into the blood vessels of the kidney and visualise the cells inside kidney blood vessels in order to uncover their behaviour as they respond to acute inflammatory insult to the kidney.
Modulating Inflammatory And Fibrogenic Pathways In Kidney Disease Using A Novel Antagonist Of Protease-Activated-Receptor-2

Summary
Chronic kidney disease (CKD) now affects 10% of adults in industrialised countries. Current treatments are largely ineffective. Thus developing better CKD treatments will have substantial public health benefit. Three well established and clinically relevant animal models of kidney disease will be used to test the ability of a new experimental anti-inflammatory drug, developed by members of this research team at The University of Queensland, to prevent or lessen the progression of CKD.
Treatments For Glomerulonephritis That Harness Antigen Specific Regulatory Cells

Summary
Many forms of kidney disease are caused by the immune system targeting the kidney. We now have new data that demonstrate that these forms of autoimmune glomerulonephritis are caused by an imbalance in the numbers of kidney specific inflammatory versus regulatory cells. This project seeks to test therapies that correct that imbalance by increasing the numbers of kidney specific regulatory cells.
Inflammation of the kidneys is an important, yet poorly understood cause of kidney disease in Australia. This project will define the role of some of the immune cells, called Th17, that usually act to protect us from infection, but can turn rouge and may cause kidney damage.
TAK1 - A Novel Regulator Of Renal Inflammation And Fibrosis.

Summary
Renal failure is a major health problem in our community. Recent in vitro studies have identified a protein that plays a critical role in the induction of inflammation and fibrosis - processes central to the progression of kidney disease. This project will use a genetic-based approach to determine if this regulator plays a critical role in the pathogenesis of experimental kidney disease. If successful, these studies will identify a new therapeutic target for the treatment of kidney disease.
Kidney disease occurs in up to 50% of patients with insulin-dependent (type 1) and non-insulin-dependent (type 2) diabetes. The increasing rate of diabetes in our community has made it a major cause of kidney disease and a growing health problem. Despite clinical attempts to control blood glucose and blood pressure levels, kidney disease in most diabetic patients progresses towards a complete loss of kidney function. In severe cases, the survival of the patient is dependent upon lifelong dialysi ....Kidney disease occurs in up to 50% of patients with insulin-dependent (type 1) and non-insulin-dependent (type 2) diabetes. The increasing rate of diabetes in our community has made it a major cause of kidney disease and a growing health problem. Despite clinical attempts to control blood glucose and blood pressure levels, kidney disease in most diabetic patients progresses towards a complete loss of kidney function. In severe cases, the survival of the patient is dependent upon lifelong dialysis or transplantation, which are costly and complicated treatments. Therefore, there is an urgent need to improve treatment stategies in diabetic patients to avoid kidney failure. Recent evidence in human and experimental models of diabetic kidney disease has indicated that macrophages infiltrate the kidney during the disease process. Our previous knowledge from other inflammatory kidney diseases suggests that macrophages play an important role in promoting the progression of disease and, in some of these diseases, treatment strategies which block macrophage function and accumulation have been shown to be effective in inhibiting the disease. The overall aim of these studies will be to determine the importance of macrophages in the pathogenesis of diabetic kidney disease and identify the mechanisms regulating their recruitment and activation within the diabetic kidney. This will be achieved by examining the progression of kidney disease in type 1 and type 2 diabetic mice which have been genetically modified to prevent macrophage accumulation and activation within the kidney. These studies will provide valuable information into the pathogenesis of diabetic kidney disease and will identify whether therapeutic strategies targeting macrophages can help prevent kidney loss in diabetes.Read moreRead less
