Comparative phenotypic analysis of different blood B cell-subsets from controls and SLE patients. Indicated B cell-subsets were examined for the surface expression of several molecules including CD80, CD86, CXCR3, CXCR4, CD95 and 9G4. Bar histograms show the percentages of positive B cells (mean ± SEM) for each marker in healthy controls (N = 10; open bars) and SLE patients (N = 10; grey bars). P values were calculated using the Mann-Whitney U test, and statistically significant p values are marked with an asterisk (P < 0.05).
