Modulation of the phenotypic markers density of A549 by inflammatory cytokines. These results were obtained from the same samples as those presented in Figure 2 but relative medians of fluorescence intensity (MFI) were analyzed. Results are represented by the medians and the inter-quartile ranges obtained for seven independent experiments. A value of P <0.05 was considered to be significant. * P < 0.05;** P < 0.01; *** P < 0.001. I100: IFN-γ 100 ng/ml; T50: TNF-α 50 ng/ml; I50/T25: IFN-γ 100 ng/ml, TNF-α 25 ng/ml.
