The main purpose of this study is to understand how airborne fungi affect asthmatics who are allergic to them. Fungi or moulds release large numbers of spores into the air that are inhaled. In many cases fungal spores outnumber other particles that carry allergen, such as pollens or cat dander, by 100 to 1. This makes fungi the most common potential allergen in the environment. Fungi have been associated with respiratory diseases including fungal sinusitis, asthma, rhinitis, allergic alveolitis ....The main purpose of this study is to understand how airborne fungi affect asthmatics who are allergic to them. Fungi or moulds release large numbers of spores into the air that are inhaled. In many cases fungal spores outnumber other particles that carry allergen, such as pollens or cat dander, by 100 to 1. This makes fungi the most common potential allergen in the environment. Fungi have been associated with respiratory diseases including fungal sinusitis, asthma, rhinitis, allergic alveolitis and sick building syndrome. Largely due to their diversity and complexity, allergenic fungi have not been well studied and the ways in which individuals vary when inhaling spores is not known. Unlike other allergenic particles, it is unlikely that fungal spores release their allergen as soon as they are inhaled because we have shown in earlier in vitro studies that fungi continue to release allergen over time and this is likely to be the case when they are inhaled. Our laboratory has developed two new techniques that allow us to measure how many spores people inhale and whether they are allergic to them. This study will use these tools to detect and identify the important allergenic fungi involved in domestic and outdoor exposure of asthmatics, the degree of contribution to the total allergen load to which subjects are exposed and identify in what conditions fungi are the causal agents in location-specific symptoms. This study will also investigate allergen production of fungi in situ in the human nose, which will have application in allergic sinusitis and asthma amongst other respiratory diseases. We will investigate how readily allergenic spores germinate in the nose and under what conditions they release allergen.Read moreRead less
Bio-molecular Studies For Improved Diagnosis And Management Of Australian Children With Fish Allergy
Funder
National Health and Medical Research Council
Funding Amount
$496,602.00
Summary
Allergy to fish among children is often life-long and emerging as a significant healthcare issue worldwide, while management of fish allergy is challenging due to the lack of reliable diagnostic assays. This research grant will lead to the development of novel diagnostics for fish allergy in Australia, addressing aspects of the worldwide food allergy epidemic and forms the ideal platform for the study of fish specific allergens, generating novel knowledge for greatly improved patient management.
Development Of Clinical Algorithms To Diagnose And Predict Prognosis Of Food Allergy

Summary
Australia has the highest rate of food allergy internationally. Despite ongoing research into the area, there is currently no cure, with patient avoidance the most effective mode for the prevention of food allergy. A food challenge still the gold standard for food allergy diagnosis, and although definitive, is associated with a risk of anaphylaxis. My research aims to identify the biological differences between active disease and being healthy to develop novel diagnostic methods for food allergy
Human CD4+ T-cell Epitope-based Therapeutic For Peanut Allergy

Funding Amount
$403,121.00
Summary
Peanut allergy affects ~2% of the population and peanuts are the major cause of fatal food-induced anaphylaxis. Peanut allergy usually appears in infancy and persists indefinitely. At present, unlike grass pollen allergy, there is no preventative treatment. Using blood cells from peanut-allergic patients, we will identify the components of major peanut allergens to use in _allergy shots� to develop tolerance on peanut exposure without risking anaphylaxis.
