Summary
Kidney disease is the 10th most common cause of death in Australia. Glomerulonephritis (GN) is a major cause of kidney disease. Autoimmunity underpins disease in most patients with the most severe forms. Following the discovery of the peptide that is the target of this autoimmunity promising new biological treatments are possible. This grant will assess the capacity of four emerging therapies to turn off injurious autoimmunity and treat disease.
The Therapeutic Role Of Complement Inhibition In ANCA Associated Glomerulonephritis

Summary
ANCA associated vasculitis is an inflammatory disease involving the kidney filters which is a major cause of chronic kidney failure. Current drugs to treat it are toxic. Less toxic treatments are required. In this study we will explore the potential for new treatments targeting complement (a normal blood protein involved in inflammation) to attenuate this disease in mice. We hope to define the role of complement in this disease and the benefits of inhibiting it before we use it in humans.
Targeting Tregs Using Chimeric Antigen Receptors (CARs) For The Treatment Of Autoimmune Renal Disease

Summary
Chronic Kidney Disease is one of the major causes of death in Australia. Therapeutic success with regulatory T cells (Tregs) capable of targeting autoimmune kidney disease would have major clinical implications. In the proposed study, we will use Chimeric Antigen Receptors (CARs) T cells by redirecting them to diseased organs, protect against kidney injury. These CAR T cells will recognise renal antigens and target immune cells and antibodies to limit kidney damage.
Imaging Neutrophil And Endothelial Function In Acute Glomerulonephritis

Summary
The glomerulus is a group of small blood vessels which form the filtering component of the kidney. In many diseases, it can be the target of an inappropriate inflammatory response during which white blood cells accumulate in the glomerular blood vessels and cause damage. In this project, we will visualise the blood vessel lining of the glomerulus in order to understand how white blood cells damage this region and cause leakage of protein leak into the urine.
To Search For Genetic Causes Of Renal Disease In The Tiwi Island Aboriginal Population

Summary
This project aims to continue work done on identifying the genetic basis to the kidney disease suffered by the Tiwi population from Bathurst and Melville Islands. It is based on the outcomes of the first genome-wide scan in an Aboriginal population. The scan yielded a genetic association to a locus that has led to a very plausible hypothesis. If this hypothesis is correct, and the goal of this project is designed to find this out, then public health measures should be able to halt the progressio ....This project aims to continue work done on identifying the genetic basis to the kidney disease suffered by the Tiwi population from Bathurst and Melville Islands.

How The Kidney Is Injured By CD8+ Cells In Vasculitis

Summary
People with severe kidney disease often have inflammation in the small blood vessels within their kidneys, known as vasculitis. Human observational studies suggest that a type of immune cell, the CD8+ cell, may be critical to disease outcome, but there is no functional evidence for this. The current studies will define the role of these CD8+ cells in disease so that better treatments for humans with vasculitis can be considered.
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.
MPO-ANCA GN is a major cause of renal failure. Current treatments are toxic and poorly effective. Excessive DNA production resulting in prominent deposits of extracellular DNA are seen in glomeruli of patients with MPO-ANCA GN. This study will look at the pathological role of DNA and in a relevant animal model, use DNase I treatment to dissolve deposited DNA and treat anti-MPO autoimmunity and GN. This evidence will allow the introduction of DNase I in clinical trials.
