Airway inflammation in allergic aspergillosis: characterisation, immunologic mechanisms and treatment.

点击翻译按钮获取中文摘要

Aspergillus fumigatus is a fungus that commonly occurs in our community. In some people with asthma, this fungus causes the asthma to become severe and chronic. It may also be associated with a severe form of lung destruction called bronchiectasis. There is little known about the chemicals produced by the body which contribute to inflammation in this condition. Similarly, it is not known why only some people with asthma develop an allergic disease to this fungus. In this project we will examine 2 important inflammation chemicals (called cytokines) to examine what their role is in aspergillus associated allergy. We will also examine 2 genetic markers to establish whether these predispose to people developing allergy to aspergillus. The treatment of aspergillus lung disease is also problematic. In this project we will examine whether a new medication called itraconazole is effective in removing this fungus from the airway and improving asthma.
