Clarithromycin Inhibits Interleukin-13–Induced Goblet Cell Hyperplasia in Human Airway Cells

IL-13 is a T-helper class 2 cytokine that induces goblet cell hyperplasia and mucus production in airway epithelial cells. Because macrolide antibiotics are known to have immunomodulatory and mucoregulatory properties, the aim of this study was to examine the effect of clarithromycin on IL-13-induced goblet cell hyperplasia and mucin hypersecretion in normal human bronchial epithelial (NHBE) cells. NHBE cells were cultured to differentiation at...
