Summary
Emphysema is a major cause of illness and death and there are no effective treatments. It is caused by smoking that damages the airways and air sacs but how this occurs is not well understood. We have found that a new factor, called Toll-like receptor 7, is involved in emphysema. In this study we will now characterise its roles in this disease, work out how it induces emphysema and test new inhibitors (antibodies) that we have developed as treatments.
Identification And Therapeutic Modulation Of Sphingolipids As Novel Lung Macrophage-targeted Treatments For COPD/emphysema

Summary
COPD/emphysema is predicted to be the third leading cause of death woldwide by 2010. We have shown defective lung macrophage function in COPD and have shown that we can modify the macrophage function with novel therapies. We are now investigating a specific “sphingosine” pathway to see if it can provide us with more specific information. We aim to provide a better, more specific, adjunct treatment for the disease.
The Molecular Basis By Which The Interleukin-6 Cytokine Promotes Emphysema

Summary
Interleukin 6 (IL-6) is a potent immuno-modulatory cytokine that is commonly elevated in emphysema, the 5th leading cause of death in Australia. To understand the role of IL-6 in emphysema, we aim to demonstrate here by using a unique mouse model for IL-6-driven emphysema and clinical biopsies from emphysema patients, that IL-6 uses an alternative signalling mechanism in emphysema termed trans-signalling. Therefore this project could provide novel therapeutic targets for emphysema.
Novel Role Of Inflammasomes In The Molecular Pathogenesis Of Emphysema

Summary
Emphysema is a chronic lung disease that is caused by dysregulation of the immune system, leading to inflammation and destruction of lung tissue. Although emphysema is associated with cigarette smoking, the key components of the immune system which promote emphysema remain ill-defined. Using elaborate mouse models for emphysema, together with biopsies from emphysema patients, our aim is to reveal the role of a protein complex in the immune system called the inflammasome in driving emphysema.
Targeting Oxidant-dependent Mechanisms That Drive COPD And Its Co-morbidities

Summary
Chronic obstructive pulmonary disease (COPD) is a lung disease that is the 4th leading cause of death worldwide. There is currently no effective therapy to treat people with COPD, which costs the Australian community over $8.8 billion/year. Much of the disease burden and health care costs in COPD is associated with the management of its comorbidities (i.e other chronic medical conditions such as heart disease). This project will develop novel therapies to treat COPD and its comorbidities.
Targeting Oxidant-dependent Pathways To Improve Stroke Outcomes In COPD

Funding Amount
$1,069,574.00
Summary
Chronic Obstructive Pulmonary Disease (COPD) is a major incurable global health burden and is the 4th largest cause of death worldwide. Patients with COPD are at increased risk for stroke and this is even higher in the weeks following a lung viral infection. The reason for this is unknown so the aim of this study is to determine why people with COPD are at increased risk for stroke and then develop novel treatments to prevent or reduce stroke in COPD patients.
