Summary
Ischemic stroke remains the second leading cause of death in Australia. This project aims to understand the role the innate immune system plays in neuronal cell death following ischemic stroke. We will use cellular and animal models of ischemic stroke, as well as examine patients affected by stroke, to explore and inhibit potential damaging immune factors generated by stroke tissue. By exploring these immune pathways, we aim to identify novel therapeutic targets to treat ischemic stroke.
Age-related macular degeneration, involves the progressive loss of light sensitive cells from the retina, and is a major cause of loss of vision, and quality of life, in people over 60. Activation of immune mechanisms have been implicated in the disease, but it is not understood, why the immune system attacks vision cells. This study looks at the mechanisms of the activation of immune cells and will test treatment strategies to minimize immune activation, and thereby prevent blindness.
Targeting The Complement Activation Fragment C5a To Improve The Outcome From Spinal Cord Injury

Funding Amount
$406,838.00
Summary
This project will focus on the development of a new drug that is designed to attenuate the harmful inflammatory response that follows from spinal cord injury (SCI). The experiments will determine if the therapeutic targeting of an immune receptor molecule, called C5aR, can protect compromised neural tissues after injury against harmful inflammation and degeneration whilst also explore the mechanism behind the therapeutic effect.
The Therapeutic Role Of Complement Inhibition In ANCA Associated Glomerulonephritis

Funding Amount

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 The Complement Cascade: A Novel Therapeutic Strategy For Metastatic Melanoma

Funding Amount
$546,496.00
Summary
The incidence of melanoma is increasing world-wide, and Queensland has the highest rate of melanoma in the world. Despite advances in treatment, the 3-year survival rate for metastatic melanoma remains extremely low. This project builds on our recent research demonstrating a role for a key component of the innate immune system (complement C3a) in melanoma growth. Specifically we seek to investigate the potential of C3a as a therapeutic target for metastatic melanoma.
Complement Inhibitors For Treatment Of Chronic Inflammatory Diseases

Funding Amount
$623,606.00
Summary
We aim to provide new therapeutic approaches to gum disease, which not only causes tooth loss, but also contributes to other diseases, such as cardiovascular disease and diabetes. We will find new methods to inhibit a system in our own bodies that contributes to inflammation and gum disease and test the effects of these methods of inhibition in disease models. In this way, we hope to lessen the burden of gum disease on the Australian population.
Therapeutic Targeting Of Complement C5a Receptors In HuntingtonÍs Disease

Funding Amount
$468,312.00
Summary
HuntingtonÍs disease is a genetic neurodegenerative condition leading to progressive cognitive and motor deficits and eventual death. This research aims to explore the role of immune and inflammatory pathways in the progression of disease in patients suffering HuntingtonÍs disease, as well as in an animal model of this condition. By exploring these immune and inflammatory pathways, we aim to identify novel therapeutic targets to treat HuntingtonÍs disease.
Mechanisms And Targets Of Antibody-complement Interactions That Neutralize Malaria

Funding Amount
$647,977.00
Summary
Our project aims to identify immune mechanisms that neutralize malaria from the moment of inoculation by a mosquito, before infection can become established to prevent the development of malaria disease. Furthermore, we will discover specific targets of protective immune responses. We expect this project will provide major new advances in our knowledge of human immunity to P. falciparum malaria, one of the world’s most significant causes of mortality and morbidity, and we will use this knowledge
Complement Activation As A Therapeutic Target And Clinical Biomarker For Parkinson's Disease

National Health and Medical Research Council
Funding Amount
$497,941.00
Summary
Parkinson’s disease is the second most common neurological disease in Australia, yet there is no treatment to slow disease progression. Our study is investigating inflammation within the brain as a major contributing factor in Parkinson’s disease. We will examine this inflammatory pathway in human patients suffering from Parkinson’s, and will test a novel anti-inflammatory drug in animal models of Parkinson’s disease, in order to identify a novel treatment to reduce disease pathology.
Does Excess Consumption Of Dietary Advanced Glycation End Products Activate The Complement Pathway Contributing To Diabetic Nephropathy?
Funder
National Health and Medical Research Council
Funding Amount
$470,617.00
Summary
Modern lifestyle is characterised by the consumption of foods that have been highly processed to improve their shelf life and flavour. However, this food processing has been shown to generate potentially harmful compounds, Advanced Glycation End Products (AGEs) that may promote inflammation and worsen diabetic kidney disease. This study investigates the effects of overeating a diet high in AGEs on the function of the kidney, and aims to find out how these AGEs lead to kidney damage.
