Exposure of bronchial epithelial cells from COPD patients, healthy smokers and non-smokers to rhinovirus-1A lead to similar levels of IFNβ, IFN-λ1 and viperin induction (n = 6). Bronchial epithelial cells were obtained by bronchial brushings. Cells were infected with rhinovirus for 48 h or 72 h. Levels of mRNA were assessed by real-time PCR.
