Correlations among different subsets of B cells and the serum concentration of IL-10 in HSPN patients.

<p>Potential correlations among the numbers of B cells of different subsets and the serum concentration of IL-10 were analyzed by the Spearman correlation tests. Data are expressed as the means or concentrations for individual subjects that participated in two separate experiments. (A-B) The number of CD38⁺CD19⁺ B cells was negatively correlated with the serum IL-10 level and the percentage of IL-10⁺CD19⁺ B cells. (C-D) The number of CD86⁺CD19⁺ B cells was negatively correlated with the serum IL-10 level and the number of IL-10⁺CD19⁺ B cells. (E-F) The serum IL-10 level was positively correlated with the numbers of CD1d⁺CD5⁺CD19⁺ and IL-10⁺CD1d⁺CD5⁺CD19⁺ B cells.
