Summary
Diseases affecting the blood vessels in the lungs cause early death and the currently available treatments are not curative. We will take advantage of the latest developments in the understanding of the molecular basis of these diseases to design and test a new treatment approach using cells and cell-derived products as a therapy.
This program of work focuses on smoking related lung diseases including chronic bronchitis and emphysema, and lung cancer, as well as diseases affecting the blood vessels in the lungs. The work includes basic cell biology and human clinical trials.There is a high likelihood that new approaches to treating lung disease will emerge.

Summary
Inhalers are the primary form of treatment for asthma, allowing the delivery of lower doses of medication directly to the lungs. Consistent daily use of these inhalers is often necessary to effectively control the symptoms of asthma. Inhalers are now increasingly used to treat infants with lung problems. Many of these inhalers are not designed for use by such young children, who may be unable to perform the breathing techniques necessary for effective use of these inhalers.

Consistent daily use of these inhalers is often necessary to effectively control the symptoms of asthma. Inhalers are now increasingly used to treat infants with lung problems. Many of these inhalers are not designed for use by such young children, who may be unable to perform the breathing techniques necessary for effective use of these inhalers. Not all the drug inhaled by patients will end up in the lungs where it is needed; a large proportion is left in the mouth, throat and stomach. Our earlier studies have shown that there is a large amount of variability in the amount of drug received by children using inhalers. We intend to assess the important factors involved in improving the efficiency of inhaler therapy for children, such as the size of the inhaled particles and the breathing pattern of the child. The results obtained from this study will enable us to determine the best method of delivering these drugs to children so that they only receive the lowest effective dose for treatment of the symptoms of asthma while minimising unwanted effects.Read moreRead less

It is expected to cost communities hundreds of billions of dollars in compensation. This disease is usually already quite advanced by the time a patients presents to a doctor with symptoms so we have been working on methods of early detection. This project studies a new, exciting method of diagnosis using blood levels of a molecule called 'SMRP'. Late last year we published a paper in the prestigious journal Lancet showing that SMRP was a good test to help diagnose mesothelioma and this became a lead news item around the world because of widespread concern about this disease. In those studies we found strong clues that this test was very sensitive and could detect mesothelioma a year or so before a patient develops symptoms. In this grant we will evaluate whether this test could be useful for screening asbestos-exposed individuals for early detection of this cancer. We will also study ways of improving the test using laboratory methods. This would provide a foundation for studies aimed at determining if early treatment could improve patient survival.Read moreRead less

Summary
Chronic airflow limitation is a major cause of illness and death in Australia. Long term oxygen therapy is well established as one means of assisting people with chronic lung disease. Survival is still poor particularly when an individual is hypercapnic. Non-invasive ventilation used at night with a mask has been used in chronic hypercapnic respiratory failure from other causes with very good results.

Long term oxygen therapy is well established as one means of assisting people with chronic lung disease. Survival is still poor particularly when an individual is hypercapnic. Non-invasive ventilation used at night with a mask has been used in chronic hypercapnic respiratory failure from other causes with very good results. This study looks at whether non-invasive mask ventilation improves survival, improves clinical outcome measures and reduces health costs in people with chronic airflow limitation. The ventilatory support will be used at night during sleep and will be a bilevel positive airway pressure device. Apart from measuring the cost-benefit of home ventilatory support, this study will examine the relationship between the time of commencement of home ventilatory support and outcomes. In addition the relationships between daytime awake PaCO2, lung function, and body mass in CAL patients and the likely response to home ventilatory support will be examined.Read moreRead less

Summary
People with cystic fibrosis (CF) produce thick mucus that is not cleared normally from the lungs. This retained mucus often becomes infected, which progressively damages the lungs. Various physical therapies which may help clear secretions are being used in CF. These include several types of devices which provide positive pressure to the airways. However, it is not known to what extent these devices, or other interventions such as manual chest physiotherapy and exercise, enhance mucus clearance. ....People with cystic fibrosis (CF) produce thick mucus that is not cleared normally from the lungs. This retained mucus often becomes infected, which progressively damages the lungs. Various physical therapies which may help clear secretions are being used in CF. These include several types of devices which provide positive pressure to the airways. However, it is not known to what extent these devices, or other interventions such as manual chest physiotherapy and exercise, enhance mucus clearance. As a result, it is not currently possible to scientifically prescribe intervention(s) to enhance mucus clearance in CF. This is partly because much of the research that has been performed in this area has been poorly-designed or has used inaccurate measures. Also, recent research has shown that these therapies may have significant effects beside their effect on mucus clearance. For instance, bacterial infection and the exchange of oxygen and carbon dioxide between the blood supply and air in the lung may all be affected by these interventions. Notably, the extent of benefit or detriment seen in these parameters does not always correlate with the effect on mucus clearance. We therefore believe a series of experiments is necessary to provide evidence upon which the scientific selection of mucus clearance therapies may be based. We have developed a new technique which allows clearance of mucus from the airways to be objectively measured in three-dimensions (3D). We intend to use the 3D technique to examine the effects of three different positive pressure devices, exercise, and manual chest physiotherapy on mucus clearance. Based on the outcomes of this research, we intend to compare the most appropriate therapy to performing no mucus clearance therapy in a short term trial. This trial will assess changes in the following: bacterial infection, mucus plugging in the airways, how well the lungs move air and exchange oxygen and carbon dioxide, and the patient's quality of life.Read moreRead less
Elucidating The Roles And Mechanisms Of Activation Of NLRP3 Inflammasomes And Developing Therapeutic Interventions For Severe Steroid-resistant Asthma

Funding Amount
$961,929.00
Summary
Severe asthma is a major clinical issue. There are no effective treatments because we don’t understand how it occurs. We have identified a factor called an “inflammasome” that we think causes severe asthma. We have produced a new inhibitor of this factor, and shown experimentally that it may suppress important symptoms of severe asthma. We now aim to work out precisely how this inflammasome causes severe asthma and progress our new inhibitor towards therapeutic development.
Targeting Neutrophil Extracellular Traps To Reduce Inflammation In Severe Asthma
Funder
National Health and Medical Research Council
Funding Amount
$585,240.00
Summary
People with severe asthma, a chronic disease of the lungs, often have many inflammatory cells in the airways called neutrophils. Neutrophils release a meshwork of fibers in a web like trap called NETs, which are made of the cells DNA and other proteins that fight infection. These NETs can promote inflammation in the persons airways. Current asthma treatments have no effect on NETs. This project will measure NETs in the airways and test a new treatment to reduce NETs, and relieve asthma symptoms.

Summary
The current project aims to determine how obesity causes obstructive sleep apnoea (OSA), a disorder associated with significant cardiovascular morbidity & mortality. This research is a burgeoning area given that obesity is one of the western world’s leading health care concerns. Our findings may ultimately offer a refinement of weight-loss interventions to maximise their effects on OSA as well as offering novel treatment strategies in the management of this disorder that is desperately needed.
