Impact of airway wall fibrosis on the efficacy of anti-asthma drugs

Grant number: 299823


Most episodes of asthma are controlled or prevented by current medications. In a small, but significant proportion of asthmatics (5-10%) symptoms persist despite the use of the best combinations of anti-asthma drugs. One of the reasons that acute episodes of asthma occur is that the airway tubes slowly change in structure. These changes involve an increase in the amount of collagen (part of the cement between cells) making the airway stiffer. In this project, we are exploring the impact of the stiffening of the airway on the way that different cells within the airway wall respond to drugs used to treat asthma. Our initial findings suggest that when the airway wall becomes stiffer with more c..
