Understanding The Mechanisms Of Steroid Resistant Inflammatory Pathways In Mouse Models Of Asthma: Potential New Treatment Approaches
Funder

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.
Epithelial-Mesenchymal Cell Communication; Towards New Therapeutic Targets For Fibrosis

Funding Amount
$794,596.00
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.
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

Funding Amount
$714,061.00
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.
Characterising The Pro-inflammatory Role Of IL-36γ/IL-36R In Pathogen-induced Exacerbations Of Asthma And COPD

Funding Amount

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.
Mast Cell Proteases Suppress Respiratory Viral Infections And Alleric Inflammation Of The Airways

Summary
Severe RSV infection and asthma accounts for poor quality of life in our community and current treatments have limited effects. Although the factors regulating these disorders are poorly understood, mast cells (MCs) may play important roles. We have shown MC protease-6 protects against viral infection. Here we will identify how MC and their factors are involved in the control of severe respiratory infections and allergic disease of the lung, and identify potential new ways to treat these conditi ....Severe RSV infection and asthma accounts for poor quality of life in our community and current treatments have limited effects.

Targeting MicroRNA (miRNA) As A Unified Therapeutic Approach To The Treatment Of Asthma And Allergic Inflammation

Summary
Approximately 30% of our community suffers from allergic inflammation (asthma/rhinitis/dermatitis) that results in poor quality of life. The factors regulating these disorders are poorly understood and current treatments only target the symptoms and not the cause of disease. MicroRNA control gene expression and are emerging as potential regulators of inflammation. This project will identify the role of microRNA in the regulation of allergic diseases and their potential as new therapeutic targets ....Approximately 30% of our community suffers from allergic inflammation (asthma/rhinitis/dermatitis) that results in poor quality of life.

The Link Between Vitamin D Deficiency And Chronic Lung Disease Is Due To Increased Airway Smooth Muscle

Funding Amount
$644,067.00
Summary
Vitamin D deficiency is a global public health problem. It is becoming increasingly evident that vitamin D deficiency increases the severity of chronic lung disease. In this study we propose to examine a mechanism that we think clearly explains this association. These studies are critical to understanding how deficiencies in key nutrients can impact on chronic lung disease and will provide the data necessary to guide public health policy to reduce the burden of disease in the community.
Targeting An Epigenetic Silencing Pathway To Treat Allergic Asthma

Funding Amount
$318,768.00
Summary
Asthma affects around 11% of the Australian population and costs the health care system around $28 billion. Unfortunately there is still no cure and treatments have not changed for decades. This project aims to discover new drugs to treat asthma by re-wiring the cells of the immune system which cause the disease.
Fetal Growth Restriction, Low Birth Weight And The Development Of Asthma

Funding Amount
$397,003.00
Summary
Asthma is a common disease in Australia that causes breathing difficulties. Studies have shown that restricted growth in the womb may be linked to developing asthma in childhood and adulthood. The reason for this isn't clear but we believe that restricted growth may alter the normal development of the baby's airway and lungs. Changes to the normal structure of the lungs leads to a higher risk of developing asthma.
