(Left) RSV stimulates airway epithelial NADPH oxidase (Nox), metalloproteinase (MP), and ligand-induced activation of EGFR. EGFR activation suppresses IRF1-induced IFN-λ. (Right) In the presence of EGFR inhibition (e.g., Gefitinib, AG 1478, and siRNA), IRF1-induced IFN-λ is increased, which results in decreased viral titers. Figure is adapted from Reference 6.
