Summary
The CCRE will enhance Australia's international research reputation in clinical respiratory and sleep medicine by enhancing links between hospital-based investigators. This will foster development of new clinical researchers in these fields. Major research projects will include reducing side effects of asthma therapy in the elderly, better and cheaper ways of diagnosing disorders such as sleep apnoea and blood clots in the lung, keeping patients with chronic lung diseases out of hospital and avo ....The CCRE will enhance Australia's international research reputation in clinical respiratory and sleep medicine by enhancing links between hospital-based investigators. This will foster development of new clinical researchers in these fields. Major research projects will include reducing side effects of asthma therapy in the elderly, better and cheaper ways of diagnosing disorders such as sleep apnoea and blood clots in the lung, keeping patients with chronic lung diseases out of hospital and avoiding accidents due to lack of sleep.Read moreRead less
Elucidating The Mechanisms Of Infection-induced, Steroid-resistant Asthma

Summary
Steroid-resistant asthma is an important clinical problem and effective therapies are urgently required. Substantial evidence links bacterial and viral respiratory infections with steroid-resistant asthma, however, how infections are associated with steroid-resistant asthma is not known. This project will investigate the role of specific immune factors, that we have identified, in infection-induced steroid-resistant asthma. Our project may identify new therapeutic targets for this severe form of ....Steroid-resistant asthma is an important clinical problem and effective therapies are urgently required.

Targeting The Shared Beta-chain Of The IL-3, IL-5 And GM-CSF Receptors As Therapy For Allergic Inflammation
Funder
National Health and Medical Research Council
Funding Amount
$610,037.00
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 therapies targeting a common receptor pathway with the potential to completely suppress acute and chronic disease whilst maintaining a single molecular target. We will perform preclinical testing of antibodies for treatment of allergic disorders using a novel mouse strain expressing the human form of this receptor
Extending The MIS BAIR Randomised Trial Of BCG To Prevent Childhood Allergy And Infection
Funder
National Health and Medical Research Council
Funding Amount
$939,504.00
Summary
BCG (used till recently to prevent tuberculosis) is a potential low cost and readily available vaccine which could reduce the rates of allergy and infection in Australian children. We propose to extend our existing NHMRC-funded trial, which studies whether BCG vaccinatinon given at birth prevents the development food allergy, eczema and infection in the 1st year of life, to see if this effect continues until 5yrs of age. At this age, we can also see if BCG vaccination at birth prevents asthma.
Epithelium-fibroblast Interactions In Response To Allergic Airway Inflammation

Funding Amount

Summary
The airways of an asthmatic patient undergo dramatic structural changes over time. This remodelling is thought to be responsible for producing the changes in lung function that are frequently observed in someone with the disease. However, in contrast to normal wound repair, it is unclear why in the majority of asthmatics, inflammation leads to ongoing remodelling rather than a self limiting healing process. In this context, cells that line the airways (epithelium) as well as cells that sit immed ....The airways of an asthmatic patient undergo dramatic structural changes over time. This remodelling is thought to be responsible for producing the changes in lung function that are frequently observed in someone with the disease. However, in contrast to normal wound repair, it is unclear why in the majority of asthmatics, inflammation leads to ongoing remodelling rather than a self limiting healing process. In this context, cells that line the airways (epithelium) as well as cells that sit immediately beneath them (fibroblasts) are important sources of mediators and structural matrix proteins that contribute to these processes. Under normal conditions, signals from these structural proteins are transmitted to the cells via specific adhesion molecules. However, in asthma epithelial cells are frequently damaged and detached, and fibroblasts appear to proliferate and undergo changes in their appearance. This projects aims to investigate the expression and function of specific cell adhesion molecules in the epithelium and fibroblasts following airway inflammation. Specifically, this proposal aims to determine which adhesion molecules are associated with upregulated proliferation and production of matrix proteins. We will also examine the effects of two novel mediators, thought to play a role in remodelling on the expression and function of these adhesion molecules. Proliferation of these cells and the altered deposition of matrix proteins may be a key feature of airway wall thickening and hyperreactivity that is a characteristic feature of asthma. The balance of deposition and breakdown of matrix proteins is regulated by a variety of mediators. Defining what regulates the expression and activity of adhesion molecules is of fundamental importance in determining how the normal repair processes may evolve into airway wall remodelling.Read moreRead less
The Pathogenesis Of Distinct Endophenotypes Of Asthma Is Underpinned By The Collaborative Activation Of Specific PRRs.

Funding Amount
$678,754.00
Summary
Asthma is a chronic airway disease caused by inflammation. Although asthmatics can be sub-typed based on the type of inflammatory cells present in the lungs, medication specific for the treatment of these sub-types is not yet available. In this grant we will investigate the immune processes that orchestrate the development of the distinct inflammatory sub-types of asthma. This information will help us develop new therapies that will be tailored to target the appropriate type of inflammation.

Immunity To Colonising Bacteria Of The Respiratory Tract In Atopic And Non-atopic Children

Funding Amount
$246,478.00
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.
I am a clinical researcher determining: a) the role of altered airway structure, particularly airway smooth muscle and extracellular matrix, in asthma and COPD; and b) the prevalence of, and risk factors for, respiratory disease in general populations.
