Co-Expression of IL-10, CD39, CD24, CD25 and CD38 in the three sorted subsets of CD39⁺ B cells. Activated B cells were sorted for CD39 expression levels and analyzed by flow cytometry for co-expression of IL-10 (A), CD25 (B), CD24 (C) and CD38 (D–F). In (B) and (C), CD39^neg cells are green, CD39^inter cells are blue and CD39^high cells are red. In (D–E), dot plots show CD38 expression levels in CD39^neg B cells (D), CD39^inter B cells (E) and CD39^high B cells (F). The data are representative of three independent experiments (B–F). In (A), the data are mean values ± SEM of three independent experiments as determined by one-way ANOVA followed by post-hoc comparisons (Tukey). The same statistical analysis was used for the data shown in Figs. 3–5.
