Analysis of CCL17 expression in epithelial cells treated with DECMA or cytokines.

<p>Epithelial cells from the normal ethmoid were incubated with DECMA, anti-E-cadherin antibody, and the cell extract was analysed by immunoblotting with anti-E-cadherin and anti-CCL17 antibody. Representative immunoblot images (A) and graphical and statistical analysis of relative CCL17 expression (B). Epithelial cells from the normal ethmoid (C) and nasal polyp (D) were treated with Th1 cytokines TNF-α and IFN-γ or Th2 cytokines IL-4, IL-5 and IL-13 as indicated. The expression of IL-4 and IL-5 in nasal polyp epithelial cells was significantly greater than that of normal ethmoid epithelial cells. * <i>p</i><0.05.
