Th1/17-Biased Inflammatory Environment Associated with COPD Alters the Response of Airway Epithelial Cells to Viral and Bacterial Stimuli

Figure 6

Expression of mRNA for IFN-β1 by Calu-3 cells pretreated with Th1/17 cytokines, following stimulation with LPS, imiquimod, or poly I:C. IFN-β1 expression data (relative to HPRT) were transformed and analyzed by 2-way ANOVA (LPS, imiquimod: ; poly I:C: ). Graphs show fold change relative to unstimulated cells in the corresponding group (media or Th1/17 environment). Significant differences are shown as , , and . Unstim: unstimulated; Imiq: imiquimod.
