Summary
T cells that produce the cytokine IL-22 (Th22 cells) are found in infectious and inflammatory lung disease. However, the role of Th22 cells in promoting or preventing disease remains largely unknown. We have discovered how to grow Th22 cells and have generated a unique strain of IL-22 reporter mice, which will allow us to identify their role in infectious and inflammatory diseases. Our investigations will provide new insights into therapeutic approaches for these diseases of the lung.
Defining The Roles And Targeting Interferon-epsilon As A New Therapy For Influenza In Asthma And COPD

Summary
Influenza is a major cause of illness and death, especially in people with asthma and emphysema. There are issues with vaccines and current treatments are poorly effective. Effective treatments are urgently required. We have found a new immune factor, interferon-epsilon that is induced and used by influenza viruses to cause infection. We aim to understand how this occurs and to test new treatments for influenza that suppress interferon-epsilon, in healthy and susceptible individuals.
Characterising The Pro-inflammatory Role Of IL-36γ/IL-36R In Pathogen-induced Exacerbations Of Asthma And COPD

Summary
Lung infections cause exacerbations in patients with asthma and COPD and these are difficult to treat and can be life-threatening. We have discovered that the cytokine pathway, IL-36?/IL-36R, is linked to the host response to bacterial and viral infections that induce exacerbations in these patients. Our studies will provide new insight into the role IL-36?/IL-36R in infection, disease exacerbation and determine the therapeutic benefit of blocking this pathway.
Transition From Childhood To Adult Asthma: Predicting Persistent And Adult-onset Asthma In Young Adults In The Raine Longitudinal Birth Cohort

Summary
While many children grow out of their asthma a significant number continue to have asthma in later life. The Raine community birth cohort has followed newborn infants from birth and has contributed to our understanding of how asthma develops throughout childhood. The proposed project aims to assess those factors that contribute to the persistence of asthma throughout childhood in into early adult life in the as well as investigate the predictors of adult onset asthma at 23 years of age.
Dissecting The Contribution Of IL-17-producing ?? T Cells In The Pathogenesis Of Airway Diseases

Summary
Airway diseases such as severe steroid-refractory asthma and chronic obstructive pulmonary disease (COPD) are an enormous worldwide burden and have a huge public health impact. Approved drugs for these two diseases provide symptomatic relief but they do not halt the disease process, and curative therapy remains elusive. We have discovered a possible cause of chronic bronchitis, and using advanced techniques we are now probing for ways to turn this discovery into an effective treatment option.
Targeting Remodelling In Chronic Obstructive Pulmonary Disease (COPD), Chronic Asthma And Idiopathic Pulmonary Fibrosis (IPF)

Summary
Lung diseases (emphysema, asthma & pulmonary fibrosis) are major burdens on Australian community and economy. Airway remodelling/wounding is a key feature of all these diseases. Patients experience severe breathlessness seriously impacting quality of life and frequently leading to death. We will assess the potential of new targets (including IL-33), & therapy in suppressing wounding in experimental models. This may lead to a new treatment to reverse or prevent lung diseases.
Airway Smooth Muscle And Fixed Airway Obstruction: Strategies For Softening Muscle

Funding Amount
$555,643.00
Summary
In severe asthma the airways don't relax fully making breathing more difficult. The inability to relax is being addressed by exploring the behaviour of isolated muscle cells. These cells are able to compact collagen gels. The mechanisms used to compact the gel are different to those that cause rapid muscular contraction. We aim to identify the molecules responsible for the gel compaction as a first step to identifying new drugs to treat the fixed airway obstruction in severe asthma.
Asthma is a National Health Priority in Australia. This project follows the major international study of asthma and allergic diseases in adults. We will re-examine people who have taken part in previous studies in Melbourne. The project also surveys people of the same age currently living in the same area. Participants complete a short postal questionnaire. In the follow-up group, responders complete a more extensive questionnaire and come to our laboratory for clinical assessments.
What Are The Lifetime Clinical Predictors And Risk Factors For Multiple Phenotypes Of Adult Asthma, COPD And Sleep Disordered Breathing? Following Up The TAHS Cohort From 1st To 6th Decade

Summary
Breathing gets impaired and impact on the productivity and quality of life when chronic respiratory diseases rise with ageing. Adult chronic respiratory diseases are major causes of illness and death but there are still many gaps in knowledge on how best to prevent and manage these diseases. The proposed program will provide evidence to guide health policy and clinical management of these diseases. These original findings will be of great importance both nationally and internationally.
Localised Airway Reactivity As A Determinant Of Asthma Control And AHR

Summary
Asthma morbidity and mortality remain high, with drug cost, days lost from school and work. This may be due to severe asthma in which control cannot be attained. This may be due to localised regions of lung that remain persistently responsive to inhaled irritants. We will examine the location and size of these regions using 3-dimensional ventilation scanning. The potential importance of our findings is in providing a basis for improving treatment in resistant, severe asthma.
