Summary
Recent studies have shown that a single amino acid change in an enzyme called glutathione tranferase Pi (GSTP)1 protects against the likelihood of developing asthma. This enzyme is found in the cells that line the airways and detoxifies harmful chemicals such as those found in pollutants and cigarette smoke. The aim of our study is to understand how GSTP1 protects against the development of asthma.
Therapeutic Potential Of The IL-3-IL-5-GM-CSF Common Beta Receptor To Treat Upper And Lower Allergic Airway

Summary
This research aims to develop new treatments for allergic diseases such as asthma and allergic rhinitis, which remain significant public health problems in Australia. We will develop new therapies with the potential to completely suppress acute and chronic allergic disease targeting a common receptor protein that controls multiple facets of allergic inflammation. We will test antibodies intended to treat human asthma using a novel mouse strain expressing the human form of this receptor.

Summary
This project will use a panel of Zinquin-derived Zn fluorophores developed in our laboratory, as well as probes for the mammalian family of vesicular ZnT transporters, to carry out a study of the normal physiology of Zn in the respiratory system and potential abnormalities of this in patients with chronic inflammatory respiratory disease (asthma, COPD, chronic smoking). Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community. For example ....This project will use a panel of Zinquin-derived Zn fluorophores developed in our laboratory, as well as probes for the mammalian family of vesicular ZnT transporters, to carry out a study of the normal physiology of Zn in the respiratory system and potential abnormalities of this in patients with chronic inflammatory respiratory disease (asthma, COPD, chronic smoking). Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community. For example, asthma affects 12% of adults and amongst these, 15% waken weekly or more often with their asthma while 6% are hospitalized annually. There is a need to understand the basic mechanisms underlying these diseases so that new strategies can be developed to modify bronchocondtriction and inflammation. The project will provide new knowledge concerning the physiology of Zn in the respiratory epithelium and interactions between Zn deficiency and oxidants on injury in the respiratory tract. The usefulness of easily accessible nasal epithelial cells as a measure of Zn and Zn transporter levels deeper in the respiratory tract will be assessed. The project encompasses a number of fields and utilizes in vitro cellular and animal models, as well as tissues from human subjects.Read moreRead less
Immunity To Colonising Bacteria Of The Respiratory Tract In Atopic And Non-atopic Children

Summary
Evidence that seemingly harmless and common bacterial infections have a role, in the development of allergic disease has been uncovered. The development of immune responses to these microbes will be studied in children with and without allergy to inhalant allergens.
Inhibition Of Allergic Airway Inflammation By Nanoparticles

Summary
Inhaled air pollution particulate matter causes asthma exacerbations, with 'ultrafine' nanoparticles thought to play a major role. Unexpectedly, we recently found that, by contrast, administration of inert ultrafine nanoparticles prevents allergic airway inflammation. We will identify the key particle physical and chemical properties associated with this novel type of disease inhibition, study particle effects in clinically-relevant disease models and identify mechanisms of action.
