Primary tracheobronchial epithelial cells were grown to near confluence and infected with RV1B or sham. A. Total RNA was extracted twenty-four hour after infection, and the expression of IFN-β, IFN-λ1, IFN-λ2/3, IRF7, IP-10, IL-8 and GM-CSF determined by qPCR. Expression levels are represented as the ratio of the response to intact RV vs. the response to sham. The y-axis is in log scale. B–G. Time course of RV1B-induced responses in primary cells.
