Figure Lengend Snippet: Memory B cells of ATA+, euthyroid, infertile patients have increased calcium flux upon BCR activation Selected calcium flux kinetic data of memory B cell subsets: Non-switched (NSw) memory B cells, CD25- and CD25+ NSw cells: (A) maximum value, (B) ending value, (C) area under curve (AUC) value. Immunoglobulin class-switched (Sw) memory B cells, CD25- and CD25+ Sw cells: (D) maximum value, (E) ending value, (F) area under curve (AUC) value. CD27-, IgD- double-negative (DN) memory B cells, CD25- and CD25+ DN cells: (G) maximum value, (H) ending value, (I) area under curve (AUC) value. HC: healthy controls (n=12); HT: Hashimoto’s thyroiditis, H1: hypothyroid patients with HT before treatment (n=14); H2: euthyroid patients with HT, after levothyroxine-treatment, (n=12); HIE: HT, infertile, euthyroid patients (n=14). The kinetic data were analyzed by the FACSKin software. Differences between the groups were assessed with two-way ANOVA and Tukey’s post hoc test except H1-H2 comparisons where a mixed-effects analysis and the Tukey’s multiple comparisons test were used because these groups represent the same individuals in a repeated sampling before and during treatment. Data are depicted as individual values, middle line represents the mean, whiskers are set to standard deviation (SD). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
Article Snippet: PBMCs (8 x 10 6 cells) were stained with the appropriate combination of fluorochrome-conjugated anti-human antibodies in 100 μl of media in order to differentiate B lymphocyte subsets: CD5 PerCP (clone UCHT2), CD19 PE (clone SJ25C1), IgD APC (clone IA6-2), CD25 BV421 (clone BC96) (all from Sony Biotechnology), CD27 PE-Cy7(clone M-T271, BioLegend).
