Increased Frequencies of Switched Memory B Cells and Plasmablasts in Peripheral Blood from Patients with ANCA-Associated Vasculitis

Figure 3

Comparisons of B cells and subsets between patients in remission with and without a tendency to relapse. (a) Concentration of CD19⁺ B cells in peripheral blood from patients with antineutrophil cytoplasmic autoantibody- (ANCA-) associated vasculitis (AAV) in remission with () and without () tendency to relapse. (b) Percentage of transitional B cells (of CD19⁺ B cells), (c) percentage of CD95⁺ exhausted memory B cells (of exhausted memory B cells), in peripheral blood from patients with AAV in remission with () and without () tendency to relapse. The Mann-Whitney test was used to calculate the level of significance. Data are presented with medians and interquartile ranges.
