Article Title: STAT3 haploinsufficiency is associated with autosomal dominant hyper-IgE syndrome

doi: 10.1126/sciadv.adw2464

Figure Lengend Snippet: ( A ) STAT3 expression was evaluated by Western blot in Stat3 +/+ and Stat3 +/− cells derived from the spleen, thymus, and bone marrow (BM). Tubulin was used as loading control. Each lane represents one mouse. ( B ) A quantification of the STAT3/loading control ratio after normalization is shown for independently performed experiments as in (A). The mean ± SD is plotted. ( C ) IgE serum levels in Stat3 +/+ and Stat3 +/− mice were measured by ELISA. ( D ) Flow cytometry to identify IgG1 + and IgE + cells from IgM − IgD − cells 4 days after culturing Stat3 +/+ and Stat3 +/− B220 + splenocytes with IL-4 (12.5 ng/ml) and anti-CD40 antibody (62.5 ng/ml) in the absence or presence of IL-21 (25 ng/ml). Numbers in dot plots represent cell frequencies. ( E ) Mean (±SD) frequencies of the IgG1 + and IgE + cells as gated in (D). ( F ) Levels of IgG1 and IgE in the supernatant of cell cultures as done in (D) were measured by ELISA. B220 + splenocytes from Stat3 +/+ and Stat3 +/− mice were stimulated for different time points with IL-21 (50 ng/ml) ( G ), IL-10 (50 ng/ml) ( H ), and IL-6 (50 ng/ml) ( I ), and the phosphorylation of STAT3 (p-STAT3) was evaluated by flow cytometry. Mean (±SD) of mean fluorescent intensity (MFI) is plotted. Data are representative of at least three independent experiments. P values by unpaired t test (C) or two-way ANOVA followed by Bonferroni’s or Tukey’s multiple comparisons test (B and E to I).

Article Snippet: Cells were cultured in complete B cell medium [RPMI with 10% FBS, 10 mM Hepes, GlutaMAX, penicillin-streptomycin (Gibco), and 50 μM β-mercaptoethanol (Sigma-Aldrich), supplemented with IL-4 (12.5 ng/ml; PeproTech) and anti-CD40 antibody (62.5 ng/ml; Miltenyi Biotec), in the absence or presence of IL-21 (25 ng/ml; PeproTech)].
