Modulation of mucus production by interleukin‐13 receptor α₂ in the human airway epithelium

Abstract

The caption of Fig. 6 should read as follows. (a) and (b) Time course of mRNA expression of MUC5AC (b) and IL-13Rα2 (a) in normal human bronchial epithelial cells cultured with IL-13 (10 ng/mL). The results are the mean±SEM from 14 different bronchi. Significant differences from values on day 0 are indicated by *P<0.05, **P<0.02, ***P<0.005. The text citation of Fig. 6 should read as follows. No expression of MUC5AC and only a small amount of expression of IL-13Rα2 mRNA were observed before adding IL-13 (day 0) (Figs 6a and b). The amount of MUC5AC mRNA expression significantly increased from days 0 to 7 after treatment with IL-13 (10 ng/mL), and returned to baseline levels at day 21 (Fig. 6b). The IL-13Rα2 mRNA expression increased from days 0 to 7 after adding IL-13 (10 ng/mL). Increased IL-13Rα2 mRNA expression was also observed 21 days after adding IL-13 (Fig. 6a).
