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.
Inhibition Of Necroptosis As A Novel Strategy For The Prevention Of Bronchiolitis And Subsequent Asthma

Summary
Severe virus associated bronchiolitis is a major cause of infant mortality and a risk factor for asthma. Using a mouse model, we have shown that virus infection causes tissue damage, leading to the release of 'danger' molecules that promote excessive inflammation and tissue remodelling. We have identified an important mechanism by which the danger molecules are released. We will now assess whether blocking this process ameliorates viral bronchiolitis and breaks its nexus with subsequent asthma.
Urokinase Is A Key Mediator Of Airway Inflammation And Tissue Remodelling In Asthma

Summary
The scarring of airway tissue in asthma increases the difficulty of breathing. There is no effective treatment for airway scarring in severe asthma. This study looks at how proteins involved in dissolving blood clots influence wound healing and scarring in the airways. A better understanding of airway tissue scarring will lead to possible treatments for more serious forms of asthma which remain a major health and economic burden to our community.
Is Asthma In The Elderly A Disease Of The Peripheral Airways?

Summary
Elderly asthmatics have poorer clinical outcomes compared with younger asthmatics. The reasons for this are unclear but may involve age-related changes in the disease itself. In this project we aim to show that asthma in the elderly is dominated by abnormalities of very small peripheral airways, in contrast to younger patients where the abnormalities occur in larger airways. The results will provide the basis for new and better targeted treatment strategies for asthma in the elderly.
Impaired Respiratory Tolerance In Obesity - The Link With Asthma?

Summary
Australia has one of the highest obesity rates in the world, placing a major strain on health budgets. Obesity increases the risk of numerous diseases, including asthma. Asthma is prevented in healthy people by the immune system. This project will investigate whether obesity-related dietary factors and/or gut microbes impair this immune-mediated mechanism. Outcomes will increase understanding of the effects of diet and obesity on asthma development, and lead to novel asthma therapies.
Novel Strategies To Boost Tristetraprolin Function: A Critical Anti-inflammatory Protein In Asthma

Funding Amount
$547,216.00
Summary
Asthma is a chronic disorder where airways are remodelled, resulting in poor lung function. Airway remodelling is a consequence of long-term inflammation. As current treatments halt some, but not all, aspects of airway remodelling, new therapeutic approaches are urgently required. In this grant, our aim is to devise novel strategies to boost the function of a critical anti-inflammatory protein - TTP - to reduce inflammation in asthma.
Elucidating The Roles And Mechanisms Of Activation Of NLRP3 Inflammasomes And Developing Therapeutic Interventions For Severe Steroid-resistant Asthma

Funding Amount

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.

Summary
COPD is a common condition associated with many clinical consequences that negatively impact on quality of life. The burden of illness from COPD remains high despite current treatment. There is an urgent need to improve management of COPD and we propose that individualized management targeted to airway and systemic inflammation will do this. This study will examine the effect of targeted anti-inflammatory treatment in patients with COPD and will examine the role of a simple blood test to assess ....COPD is a common condition associated with many clinical consequences that negatively impact on quality of life.

Anti-viral Immune Dysfunction In Severe Asthma Varies Across Inflammatory Phenotypes.

Summary
Common cold viruses often trigger asthma flare-ups , but have relatively minor effects on healthy people. Why this happens is not clear. We have identified two different ways in which the immune system can react badly to a common cold virus in people with asthma. In this study we will find out more about why the immune system does not react normally in a large group of people with severe asthma. This study will help us discover improved treatments that can be targeted to people with asthma.
Epithelial Drivers Of Neutrophil Plasticity In Early Cystic Fibrosis Lung Disease

Summary
Why airway inflammation becomes chronic so early in life for people with cystic fibrosis (CF) is unclear. This project will use the latest techniques to characterise immune cells found in airways of infants with CF and model in the laboratory how immune cells react to the CF airway. We will challenge CF airway cells with different bugs that can infect the lung, then see if the responses by CF airway cells can change the normal response of immune cells, triggering chronic disease.
