Improving Treatment Strategies For Chronic Alphaviral Arthritic Diseases

Funding Amount
$643,624.00
Summary
Chikungunya virus and Ross River virus cause epidemics of acute and chronic arthritic disease in humans, which is often poorly managed with current treatments. This grant seeks to understand the mechanisms that give rise to disease in order to identify improved treatment strategies. Both the persistence of viral replication in joint tissues and unnecessary inflammatory responses appear to be important factors driving chronic disease.
Using Metagenomics To Determine The Causative Agent(s) Of Tick-Borne Disease In Australia

Funding Amount
$639,428.00
Summary
Tick-borne disease has emerged as a topical and controversial public health problem in Australia. We will employ state-of-the-art techniques in metagenomics to determine what microbial species (bacteria, viruses and eukaryotes) circulate in Australian ticks and whether these or different microbes are also present in humans diagnosed with tick-borne disease. The data generated will provide key information on whether tick-borne disease has a microbiological cause and, if so, the microbes involved.
Are Chondrocytes The Target Cells Of Glucocorticoid Therapy In Autoimmune Arthritis?

Summary
Glucocorticoids (GCs) are widely used for their potent anti-inflammatory and immunomodulatory effects due to the effects GCs on immune cells or synovial fibroblasts. Recently, we have made the exciting discovery that arthritis mice with glucocorticoid receptor knock-out in chondrocyte are completely resistant to glucocorticoid treatment. This study will identify the mechanisms underlying these hormonal effects with the aim to find new targets for efficient treatments for arthritis.
This proposal aims to examine how the oral bacterial pathogen, P.gingivalis, interacts with the host to worsen the severity of disease in rheumatoid arthritis. We propose a new mechanism whereby the pathogen directly activates a major destructive host pathway to promote tissue and bone destruction, which are two of the clinical hallmarks of rheumatoid arthritis. We also propose that this host-pathogen interaction occurs in periodontal disease.
Novel Insights Into The Mechanisms Of How Chikungunya Virus Cause Disease In Humans

Summary
Many of the most dangerous and easily transmitted infectious agents are viruses. The emergence of chikungunya virus globally and the recognition of this pathogen in the aetiology of chronic diseases show the need for a better understanding of how the virus cause disease. The expected outcomes are a better understanding of human alphaviral diseases, with a view to improving prevention and treatment strategies to reduce the disease burden of CHIKV and related viruses.
Dissecting The Great Ophthalmic Masquerade: The Global Giant Cell Arteritis Genomics Consortium.

Summary
Giant cell arteritis (GCA) is the most common form of vasculitis in people over 50 years of age. If untreated it can cause catastrophic complications including blindness, though this can be prevented if treated early. Although there is clear evidence for a role of genetic factors in GCA, these have been little studied. We have established an Australian-led International consortium, with clinical, basic science and statistical expertise to thoroughly investigate this devastating disease.
Control Of Mast Cell Tryptase Function In Inflammation

Funding Amount
$302,627.00
Summary
Allergic disorders such as anaphylaxis, eczema, hay fever and asthma affect about 25% of the developed world. Australia has one of the highest asthma prevalence in the world, costing Australians about a billion dollars a year. One of the central players in allergies is the mast cell enzyme, ?-tryptase. We have discovered a new mechanism of control of this enzyme. This research will aid the development of specific and potent inhibitors of ?-tryptase for the treatment of allergic disorders.
Towards A Diagnostic Test For Juvenile Idiopathic Arthritis

Funding Amount
$661,670.00
Summary
Childhood arthritis is an autoimmune disease that affects around 6000 Australian children. It can be difficult to diagnose, but quick diagnosis is important to prevent ongoing pain and limit long term damage to joints. We have been able to use genetic information to predict which people have autoimmune celiac disease. In this project, we will find out how well genetic information can predict which children have childhood arthritis, and whether genetics can be used as a diagnostic test.
MicroRNAs As Therapeutic Targets For Osteoarthritis

Funding Amount
$921,754.00
Summary
microRNAs are small cellular RNA fragments that regulate protein expression. They have been shown to be crucial regulators of normal development and are associated with many disease processes. The goal of this project is to determine the role of microRNAs in the initiation and progression of joint degeneration in osteoarthritis and test the therapeutic efficacy of targeting microRNAs as new approach to OA treatment.
Statistical Analyses Of Whole Genome Genotype Data To Better Understand Psychiatric Disorders

Funding Amount
$543,755.00
Summary
Until now, determining an overlapping genetic aetiology between disorders, required large study cohorts of family records. Here we will use genome-wide genotypes available on independent case-control samples to estimate a shared genetic aetiology directly from the molecular data. In this way we will explore previously intractable questions, such as the relationship between rheumatoid arthritis in people with schizophrenia, a well-recognised epidemiological puzzle.
