Secretion of cytokines by maternal peripheral blood B cells immediate before delivery. Isolated maternal B cells were stimulated with LPS or CpG alone or combined with CD40L for 72 h. Supernatant was harvested, and the cytokine level was determined using a Th panel multiplex bead-based assay. Presented are the levels of IL-6 (A), TNF-α (B), IL-21 (C), and IFN-γ (D). Shown are the mean values and the SD. Data were analyzed by two-way ANOVA with Sidak's multiple comparisons test; *p < 0.05; ***p < 0.001; ****p < 0.0001.
