A new study challenges the traditional concept that asthma is solely an inflammatory condition, a finding with significant implications for future treatment. “Whilst reducing airway inflammation by inhaling steroids, the traditional treatment for asthma, is very effective for most patients, this does not address the long-term airway wall thickening and scarring that takes place in the lungs of individuals with asthma,” says Peter Howarth, a senior author on the paper from the University of Southampton.
