Altered matrix production in the distal airways of individuals with asthma.
BACKGROUND AND AIMS: Although increasing evidence suggests involvement of the distal airway in all stages of asthma, it is not known whether structural changes (defined as airway remodelling) occur in the distal airways of subjects with mild asthma and those with atopy. The aim of this study was to compare control subjects and those with mild asthma in relation to fibroblast phenotypes and remodel
