Figure 3From: CpG DNA modulates interleukin 1β-induced interleukin-8 expression in human bronchial epithelial (16HBE14o-) cellsCpG synergistically increased TNFα-induced expression of IL-8. Cells were treated with CpG in the absence or presence of TNFα. Cell supernatants were harvested and analyzed for IL-8 by ELISA. Data represent means ± SEM for 4 separate experiments (compared to TNFα alone, *p = 0.026, ANOVA).Back to article page
