Figure 4. IVIg renders DCs refractory to LPS-mediated maturation. (A) DCs were generated as described in “Materials and methods.” At day 5, immature DCs were treated
with IVIg (0.15 mM) for 12 hours followed by stimulation with LPS (1 g/mL) (middle row) or were treated with LPS alone (top row) for 48 hours. In control experiments, cells
were treated with HSA as an irrelevant protein for 12 hours followed by stimulation with LPS (1 g/mLbottom row). Percentages of cells positive for the indicated markers are
depicted in upper right corners. Dark histograms represent isotype control. (B) In a second set of experiments, immature DCs were stimulated with LPS (1 g/mL) for 3 hours
followed by incubation with IVIg (bottom row) or without IVIg (top row) for 48 hours. Percentages of cells positive for the indicated markers are depicted in upper right corners,
and MFI is indicated in parentheses. Results shown are representative of 4 independent experiments from different donors. (C) Effect of different sources of IVIg on
LPS-mediated maturation of dendritic cells. Monocyte-derived DCs were stimulated with LPS (1 g/mL) for 3 hours followed by incubation with Gammagard, Endobuline,
Intraglobin, and Sandoglobulin (0.15 mM) for 48 hours. The percentage down-regulation of MFI of surface molecules on DCs following IVIg treatment is shown. LPS-treated
DCs represented 100% expression. Data are represented as means and standard deviations calculated from 2 independent experiments from different donors. 图4 。丙种球蛋白,使区议会的难治内毒素介导的成熟程度。 (一)所产生的区议会中所述的“材料与方法”在第5天,不成熟的区议会的治疗
