The majority of stroke results from focal brain infarction, followed by substantial secondary excitotoxic damage in the surrounding areas. Tau has been shown to contribute to excitotoxicity and neurodegeneration in mouse models of Alzheimer’s disease (AD). Preliminary data show that tau reduction also protects against excitotoxic damage after experimental stroke. We aim to dissect the molecular mechanisms of stroke using a tau-deficient mouse model.
Slowing Progression Of Alzheimer’s Disease By Modulating The Kynurenine Pathway

Summary
Chronic inflammation in the brain in known to be a factor in the progression of Alzheimer's disease. We are exploring if blocking a particular enzyme in a biochemical pathway involved in inflammation, can improve symptoms, or slow progression, of the disease in animal models of AD. If results are as expected, our proposal has the potential to generate a new a therapy for AD.
Nedd4-2: A New Player In Polycystic Kidney Disease

Funding Amount
$671,995.00
Summary
Polycystic kidney disease (PKD) is a life threatening disorder affecting over 12 million people worldwide. This project is based on our discovery of a new gene that controls PKD. Using kidney specific gene knockout, biochemical and cellular approaches we will now address how this gene controls PKD. The results from this study will lead to better understanding of the underlying mechanisms that cause PKD, thus providing possible new targets for therapeutic interventions.
In Vivo Investigation Of Human PR3 Transgenic Mice: A Novel Animal Model To Understand The Role Of PR3 In Chronic Inflammation And Autoimmune Vasculitis

Funding Amount
$378,615.00
Summary
Granulomatosis with polyangiitis (GPA) is a form of vasculitis and is associated with antibodies directed against proteinase 3 (PR3). PR3 is expressed in neutrophils, monocytes and macrophages and has a number of well-characterized pro-inflammatory functions. The aim of this project is to understand the role of PR3 in inflammation and autoimmune vasculitis in vivo. This will be achieved using a transgenic mouse model expressing human PR3.
Investigating A New Regulator Of Cardiac Rhythm In Development And Disease

Funding Amount
$1,022,704.00
Summary
Cardiac arrhythmias affect a high proportion of the population (2-5%) and can cause sudden death. Whilst the aetiology of arrhythmia can vary, there are clear genetic causes. Unfortunately, our knowledge of the genetic contributors is incomplete, hampering efforts to interpret genetic sequencing information. This project will undertake functional analyses of a novel arrhythmia gene and establish where, when and how it is required for correct cardiac rhythm.
Targeting A New Regulator Of Cardiac Pathology To Protect The Heart From Cardiac Dysfunction And Arrhythmia

Funding Amount
$717,857.00
Summary
Heart failure is associated with high mortality, and treatment of this condition represents a major unmet need. We recently reported that specific lipid species are elevated in hearts of mice with heart failure. The goal of this study is to comprehensively examine the therapeutic potential of targeting these lipid species with drugs.
Novel Treatment Approaches To Prevent Joint Fusion In Ankylosing Spondylitis

Funding Amount
$477,440.00
Summary
Ankylosing spondylitis (AS) is a form of arthritis targeting the spine and pelvis that causes uncontrolled bone formation resulting in complete joint fusion, severe disability and even death for which no therapies are currently available. Using a mouse model that closely replicates the human disease we will characterise the changes causing this joint fusion and identify possible new targets to develop novel treatments.
Cellular Contributions To PAR-2's Essential Role In Periodontal Disease
Funder
National Health and Medical Research Council
Funding Amount
$648,786.00
Summary
Periodontal disease is a disease of the gums, which ultimately causes loss of teeth. It is a debilitating condition affecting about 20% of Australian adults. PAR-2, a receptor for protein-degrading enzymes, which is present on cells in the gums, is known to be required for development of the disease. This project will investigate the mechanism of PAR-2’s involvement in periodontal disease and provide ideas for development of treatments.
Molecular Dissection Of Aberrant IL6/gp130 And TGF? Signaling In The Pathogenesis Of Interstitial Pneumonitis

Funding Amount

Summary
Interstitial pneumonia (IP) is frequently observed in the group of lung diseases which affect the transfer of oxygen from inhaled air into the bloodstream. Current treatments for these diseases only effectively manage patient’s symptoms but don’t cure patients of IP. We have developed a strategy to identify the exact cell type responsible for an acute IP and the molecular intermediates that may offer novel treatments and pave the way for a possible cure for this disease.
