IFN-β decreases LPS-induced ICAM-1/VCAM-1 expression through STAT3. (A–B) CF were transfected with scramble or 200 ng of si-STAT1, si-STAT2, and si-STAT3 for 8 h, serum-deprived for 24 h, pretreated with IFN-β (500 U/ml) for 1 h, and stimulated with LPS (1 μg/ml) for 8 h. (A) The upper panel shows a representative Western blot image, indicating expression levels of ICAM-1 and GAPDH (used as charge control). The graphical analysis is presented at the bottom of each panel. Error bars indicate the SD for three independent experiments. ∗∗∗ p
