The integrity of the airway epithelium in patients with asthma is often disrupted, with loss of epithelial cell-cell contacts. Airway epithelial barrier dysfunction may have important implications for asthma, because structural epithelial barrier function is tightly interwoven with the ability of the epithelium to regulate the immune system. We propose that changes at the airway epithelial barrier play a central role in the sensitisation to allergens and pathogenesis of allergic asthma. Many of the recently identified susceptibility genes for asthma are expressed in airway epithelium. However, the exact mechanisms by which the expression of epithelial susceptibility genes translates into a functionally altered response to aeroallergens in asthma are still unknown. In this review, we will focus on the role of airway epithelial barrier function in the susceptibility to develop allergic asthma and discuss therapeutic strategies aimed at the epithelial barrier.
