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. Every year more than 1700 Australians require kidney replacement therapy for this reason and many more die of kidney failure or its complications.

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. Macrophage infiltration of kidneys is characteristic of CKD, and it has been assumed that macrophages cause damage. However, we have shown that certain types of macrophages can reduce kidney damage. This project will explore whether macrophage type can be switched from that causing damage to that reducing injury, with the aim of using this approach to treat CKD.Read moreRead less
Mineralocortioid Receptor-Mediated Injury In Progressive Kidney Disease

Summary
Diabetes is the major cause of kidney failure. Activation of a hormone receptor (the mineralocorticoid receptor-MR) can promote kidney injury. Current drugs blocking MR can suppress diabetic kidney disease but are limited by their poor specificity and harmful side effects. Our study will help improve strategies for blocking MR by identifying the cell types responsible for MR-mediated injury and by examining whether a new class of drug targeting MR is a superior therapy to current MR inhibitors.
Calcification of the arteries is a ubiquitous finding in patients with end stage renal failure. It is often mirrored by disturbed bone metabolism. Increasing evidence suggests a close relationship between bone and vascular health. This study aims to determine the role of calciprotein particles as a mediator of calcification in bones and arteries. Translating these findings to renal patients will ultimately contribute to providing a scientific basis for developing treatment for these patients.
Selective Targeting Of Acute Renal Injury By Inhibition Of The Receptor Tyrosine Kinase, C-fms.

Summary
The progression of kidney disease to end-stage renal failure is a major health problem in our community. We have identified that macrophages, a type of white blood cell, plays an important role in causing inflammatory kidney injury. This project will use clinically relevant animal models to test the therapeutic potential of our new approach to selectively remove these cells from the inflamed kidney and thereby protect it from injury.
