Summary
Asthma, a major chronic inflammatory disease affects more than 2 million Australians. Neutrophilic severe asthma is not responsive to current therapies. We have recently made a significant advance in understanding neutrophilic asthma, reporting low levels of a protein called galectin-3 (gal-3). In this project we will explore the role of gal-3 its effect on the resolution of inflammation. This study will result significantly advance the knowledge of the mechanisms of neutrophilic severe asthma.
A Novel Macrophage Lineage In Inflammation And Cancer

Summary
Macrophages are an important haematopoietic cell type that has been implicated in inflammatory and cancerous diseases. In our preliminary work we have discovered a new macrophage subset, termed the perivascular macrophage, in breast cancer. The aim of this proposal is to investigate the origin of these cells, and the role they play in breast cancer. This will tell us how we might be able to manipulate the functions of these cells in order to curtail breast cancer progression.
Gene Expression Biomarkers Predict Severe Asthma Inflammatory Phenotype, Activation Mechanisms And Treatment Response

Summary
Asthma is now recognised to be made up of several disease variants or phenotypes, which are likely to have different underlying causes and mechanisms. We lack understanding of how to identify phenotypes of asthma and how they work, and this is delaying research that will lead to improvements in treatments and patient care. This is particularly important in people with severe disease. This grant will establish a gene test to identify asthma phenotype, and further understand mechanisms and treatme ....Asthma is now recognised to be made up of several disease variants or phenotypes, which are likely to have different underlying causes and mechanisms.

Intravascular Leukocyte Trafficking During Thromboinflammation

Funding Amount
$668,742.00
Summary
Unblocking blood vessels to treat heart attack and stroke can unfortunately cause a paradoxical worsening of organ damage, due to increased inflammation upon blood flow restoration. We have identified a novel way in which this side-effect is regulated by the small blood clotting cells platelets, and the protein fibrin. We will investigate ways to reduce the pro-inflammatory role for platelets, and define safer clot busting treatments.
National Clinical Centre Of Research Excellence In Severe Asthma

Funding Amount
$2,597,952.00
Summary
Severe Asthma remains a large burden for the Australian community. It does not respond to current management approaches. We will develop and implement a targetted therapy approach to severe asthma that will involve assessment of needs of people with severe asthma, community burden form severe asthma, biomarkers and linked treatment strategies, as well as knowledge transfer tools and training of the health and medical workforce.
Inflammatory Mediators Of Liver Injury In Chronic Hepatitis C

Summary
Presently, liver disease from chronic hepatitis C and obesity represents a major health problem. Overall, approximately 50% of Australians with chronic hepatitis C are obese and these patients are at significantly increased risk of rapidly progressing to liver failure. It is now recognized that fat derived factors play an important role in regulating inflammatory responses. This grant proposal aims to gain insight into how liver and fat derived inflammatory factors interact to promote increased ....Presently, liver disease from chronic hepatitis C and obesity represents a major health problem.

The Role Of Novel G-Protein Coupled Receptors In Immunity And Inflammatory Diseases

Funding Amount
$69,684.00
Summary
Recent advances in molecular biology techniques have resulted in the identification of many novel GPCRs. Novel GPCRs expressed selectively on immune cells display a potential target for novel therapies for inflammatory diseases such as Asthma and Rheumatoid arthritis. This project aims to define the activity and significance of a novel group of GPCRs, the GPR40 family. Outcomes of this project will be further understanding of immune cell development and inflammatory disease development.
Mechanisms And Therapies In Cardiovascular Disease

Summary
Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide. The molecular and cellular processes underlying atherosclerosis, vascular injury and thrombosis are highly complex and not well understood. A multifaceted approach is needed to effectively address these key challenges. This Program brings together world experts in these areas to interrogate gaps in our basic understanding of CVD, and to develop novel therapies for CVD patients by exploiting ....Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide.

Understanding How Azithromycin Prevents Exacerbations In Severe Asthma

Funding Amount
$697,273.00
Summary
In some people with severe asthma, conventional inhaler treatments are not able to control the disease so there is a need for new treatment options. We have recently completed a large clinical trial which showed that very low doses of a common antibiotic help prevent asthma attacks in this situation. However, not much is known about how the antibiotic is working. This study will help us understand how the antibiotic is working and which people respond best.
