Initiating events in the development of allergic airway inflammation [ 2001 - 2003 ]

Research Grant

Researchers: Dr Andrew Mcwilliam (Principal investigator)

Brief description Despite recent advances we still do not understand the basic mechanisms which underlie the development of allergic airway inflammatory diseases such as rhinitis and asthma. It has been previously shown that when pollen are exposed to water they release a large number of very small starch granules which contain a number of potent allergens as well as plant steroids. In addition house dust mite allergens which are strongly associated with asthma are mostly located in small faecal pellets. Both these particles are ideally sized to enter the respiratory tract and initiate inflammatory responses. We have shown that these responses appear to be of the type that is needed to initiate allergic reactions. We intend to further study the interactions of these small inhaled allergen containing particles with cells of the respiratory tract. In this proposal we will look at both alveolar macrophages and respiratory epithelial cells. These approaches will not only provide new information about the processes of airway inflammation caused by allergens but may also define new therapeutic approaches to the treatment of these diseases.
