Airway Epithelial Barrier Function, Asthma And Aero-allergen Sensitization.

Summary
There is a strong association between allergy and asthma. This association been almost universally assumed to be causative. However, recent evidence suggests an alternative explanation ie., that the abnormal epithelium in asthma allows or facilitates sensitization to airborne allergens. This project will test this alternative hypothesis using human lung tissue and an animal model.
A Randomised Controlled Trial To Prevent Eczema, Food Allergy And Sensitisation Using A Skin Barrier Improvement Strategy

Funding Amount
$878,163.00
Summary
In this world first study, we will test if building the infant skin barrier by using daily regular skin care treatment can reduce the incidence of eczema. If successful, this trial will alter infant skin care practices and reduce the burden of allergic diseases in our community. Furthermore, as infants with eczema having a poor skin barrier, which possibly increases their risk of developing sensitisation, we will test if this intervention reduces the risk of food allergy.
Targeting MiRNA To Inhibit Leukocyte Differentiation: A Novel Anti-inflammatory Approach For The Treatment Of Asthma

Funding Amount
$601,386.00
Summary
In asthma, the symptoms are caused by an allergic reaction in the lung and the production of inflammatory cells whose maturation is guided by tiny molecules called “microRNAs”. The critical microRNAs will be identified and strategies to block their function developed and tested for their ability to inhibit allergic inflammation to evaluate this approach as a new treatment for asthma.
Understanding The Mechanisms Of Steroid Resistant Inflammatory Pathways In Mouse Models Of Asthma: Potential New Treatment Approaches

Funding Amount
$523,694.00
Summary
Steroids are used to treat asthma but some patients are resistant to therapy, and there is no effective treatment. Such patients suffer greater morbidity and mortality, and the heath care cost for clinical management is a significant economic burden. In this project we will obtain a better understanding of the mechanisms that regulate steroid-resistant components of disease, which control inflammation and narrowing of the airway. These studies will be central to the development of new therapies.
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.
A New And Effective Approach To Reversal Of Allergic Airways Inflammation By Turning Off Allergic Responses

Funding Amount
$393,514.00
Summary
Inflammatory diseases like asthma develop from misdirected immune responses. The ultimate goal of therapeutic strategies is to remove or inactivate the cells that cause inflammation while leaving other cells, for example, those required for protection from infectious diseases and tumours, unaffected. Here we propose to test a new way of turning off the inappropriate immune reaction with the goal of preventing or reversing asthma.
Inhibition Of IFN-?/? By Human Metapneumovirus And The Induction Of Inflammation

Funding Amount
$605,251.00
Summary
The newly isolated human metapneumovirus (hMPV) causes significant respiratory illness in infants, young children and the elderly. The virus can persist long-term and may predispose individuals to chronic lung disease. This proposal aims to determine the mechanisms by which hMPV infection causes respiratory disease, with a view to improving treatments and preventing disease.
Is Asthma In The Elderly A Disease Of The Peripheral Airways?
Funder

Funding Amount
$502,437.00
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.
