B cell subset distribution in the peripheral blood of APDS patients. (A) Gating strategy for the analysis of different B cell subsets. (B) Percentages of naïve B (CD19+IgD+CD27-), MZB (CD19+IgD+CD27+) and B-1 B (CD20+CD27+CD43+) cells in healthy controls (HC) and the patients (APDS). (C) Proportions of IgG+ (class-switched) B, total memory B (CD19+IgD-CD27+), and IgG+ and IgM+ memory B cells among the total memory B cells in HC and the patients. (D) Proportions of pre-plasmablast (pre-PB, CD38hiCD27hi), plasmablast (PB, CD20-CD38hi) and double negative B (DNB, CD19+IgD-CD27-) cells in HC and the patients. Grey column, HC (n=4); Open column, patient (n=5). *p < 0.05; ***p < 0.001 (unpaired t-test). Bars indicate mean ± SD.
