Fig. 8. The frequency of IL-6-producing Btr cells is decreased in SLE patients after short standard therapy.

Scatter plots show the SLEDAI scores (a), the concentration of plasma IFN-α (b), the frequencies of Btr cells (c) and Bn cells (d), and the frequencies of IL-6-producing Btr cells (e) and Bn cells (f) before and after 1-month standard therapy in 21 SLE patients. Data were analyzed by the Wilcoxon matched pairs test (a–f)
