Idiopathic pulmonary fibrosis (IPF) is a fatal disease of unknown cause which is unresponsive to current therapy. This study builds on recent work by this group highlighting the importance of a cell signalling molecule called STAT3 in the development of this disease. In particular, two cell types that utilise STAT3 signalling, epithelial cells and B cells, will be examined to see if blocking their STAT3 responses could be a novel therapeutic approach.

Summary
Smoking leads to inflammation that causes emphysema and inflammation in the lung and gut, which are major health problems. Once induced, there is a progressive decline in health and there are no effective treatments. Particular proteins and small genes have been discovered that control inflammation in these diseases. We may be able to control these proteins/genes and stop the progression of emphysema and gut inflammation. This project may lead to a completely new way of preventing and treating t ....Smoking leads to inflammation that causes emphysema and inflammation in the lung and gut, which are major health problems.

Summary
Fibrosis causes disability and death with millions of people affected each year. Current treatments are limited and there is a need to better understand the changes that drive fibrosis. In this study we will investigate how cells communicate to initiate and drive fibrosis. Using readily available drugs we will test new ways to alter cell communication to stop the disease and thus, develop a common and effective therapy that will change the future for people living with fibrosis.
Immune Recognition Of Upper Airway Microbiota In Early Life As A Determinant Of Respiratory Health In Children

Summary
The study will investigate the impact of respiratory infections during infancy on lung & immune function & respiratory health between 3-7 years of age. Children were previously enrolled in a population based birth cohort study (ORChID study) which collected detailed information about the respiratory health during the first 2 years of life with daily respiratory diary & weekly nasal swab collection. In this study lung function & immune function will be assessed annually in the same children (3-7)
Phenotypic And Functional Characterisation Of CD4 T Helper 22 Cells And Their Role In The Regulation Of Chronic Allergic Disease Of The Lung And Skin

Summary
Allergic inflammatory diseases such as asthma and allergic dermatitis are major health problems in our community that lead to poor quality of life. These diseases are induced by activation of immune cells known as T helper (Th) lymphocytes. Recently Th22 cells have been identified in patients with allergic diseases. In this study we will, for the first time, characterise these cells and determine their role in the processes that lead to chronic inflammation in asthma and allergic dermatitis.
Understanding The Role Of Th22 Cells In Regulating Respiratory Immune Responses In Health And Disease.

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.
Antiviral Defects Of The Airway Epithelium Associated With Wheeze And Atopy In Children

Summary
Asthma affects 10-15% of Australian. Repeated respiratory viral infections increase the risk of developing asthma, and are also the principal cause of asthma attacks. Asthmatics may be more susceptible to respiratory viral infections due to a defect in the innate antiviral response to infection. Here we aim to identify defects in the antiviral response of children who are at risk of developing asthma, and understand how they occur so that future therapies may be developed.
Airway Epithelial Injury And The Innate Lymphoid Cell Response In The Pathogenesis Of Allergic Asthma

Summary
Exposure to airborne particulate pollutants appears to contribute both to the development of childhood asthma and to acute severe attacks of asthma. We will investigate the mechanisms involved, using mouse models of childhood asthma and of asthma exacerbations. In particular, we will focus on the potentially critical role of a newly described population of host defence cells, and how these are activated as a result of injury of the lining cells of the airways.

Summary
Pulmonary artery hypertension (PAH) is a fatal disease primarily affecting young adults. It is caused by a defect in cells that form the vessel that carries blood from the heart to the lungs. We will use stem cells made from the skin of PAH patients to examine why the blood vessel cells from these patients fail to function normally.
