Comparison of the phenotypic profiles of DCLCs primed with or without IFIT4 over-expression. (a) Surface antigens of normal THP-1 cells were examined by flow cytometry. (b) To analyze the effect of IFIT4 on phenotypic changes of dendritic cell-like cells (DCLCs) during the process of differentiation, THP-1 cells were transfected with pEGFP-IFIT4 or pEGFP-C1; 36 hours later, cells were stimulated with granulocyte-macrophage colony-stimulating factor (GM-CSF; 50 ng/ml) and IL-4 (20 ng/ml) for 90 hours to generate DCLCs. These DCLCs primed with pEGFP-IFIT4 or pEGFP-C1 transfection were incubated with fluorochrome-conjugated monoclonal antibodies (mAbs) and the antigens of CD40, CD80, CD86, CD83, HLA-DR, CD14 and CD1a on the surface of those DCLCs were analyzed by flow cytometry. Appropriate fluorochrome or isotype control mAbs of each antibody species were used as negative controls. Shaded histograms represent isotype control antibodies. The thick line represents DCLCs primed with pEGFP-IFIT4 transfection, whereas the slender lines represent DCLCs primed with pEGFP-C1 transfection. All experiments were performed three times and a set of representative histograms was presented. IFIT4, interferon-induced protein with tetratricopeptide repeats 4.

Detection of Porcine B7-1/CD80 by Flow Cytometry

SFN inhibits LPS induced moDC maturation and enhances the phagocytic activity.moDCs at day 7 in culture were used for cell phagocytosis and cell differentiation status analysis. moDCs were pre-incubated for 1 h with or without SFN (10 μM) before stimulation for 24 h LPS (1.0 μg/ml) or to the indicated concentrations. CD40, CD80, and CD86 cellular surface markers expression were analyzed by flow cytometry (A). The flow cytometry results shown were from one experiment of two independent experiments. CD40, CD80 and CD86 mean fluorescence intensity (MFI) determined by flow cytometry (B). The flow cytometry results were combined from two independent experiments and each experiment was performed from triplications. Data are mean ± standard deviations (SD) (the letters a and b P<0.01). The phagocytic activity of moDCs was examined after stimulating with different concentration of LPS (0,5 μg/ml, 1,0 μg/ml, and 2,0 μg/ml) with or without 24 h pre-treatment with SFN (C). The mRNA expression of DCs surface markers CD40, CD80 and CD86 were quantified using qRT-PCR (D). The mRNA expression and phagocytosis results were combined from three independent experiments and each experiment was performed in four replications. The data represented as the mean ± standard deviations (SD) (* P < 0.05; ** P < 0.01; *** P < 0.001).
