Summary
A major feature of cardiac hypertrophy (enlarged heart) is accelerated cell growth and protein synthesis. This results from increased synthesis of ribosomes (the protein synthetic machinery). This study will examine a factor termed UBF whose activity is critical for the regulation of ribosome synthesis. Understanding the mechanisms controlling UBF function will provide new avenues in which to develop therapeutics to combat hypertrophic heart disease.
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

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.
Molecular Dissection Of Allergen Sensitisation And Immunotherapy: Direct Application To Precision Medicine In Treatment Of Asthma

Summary
Asthma is a major global health burden with huge socioeconomic impact. Most asthmatic patients are allergic. Allergen immunotherapy is the only treatment to alter the natural disease course, but does not work in many treated patients, and robust laboratory biomarkers for patient selection and immune monitoring of treatment success are lacking. Therefore, allergen immunotherapy is not offered to most patients who then rely on medications indefinitely. This research will address these needs.
