Figure 1. B cells decrease significantly in patients with MS during teriflunomide treatment.

Figure 1

B cells are assessed as CD3CD14CD19+ of which subpopulations are identified as B memory (B mem CD24+CD38), B mature (B mat CD24+CD38low), and B regulatory (B reg CD24+CD38high). (A) A clear trend in reduction of B-cell number and percentage was observed in 3 patients treated for 3 months. (B) B-cell percentage (upper panel) and numbers (lower panel) were reduced after 1 year of treatment with teriflunomide. Data are presented as mean ± SEM for 7 treated patients with MS. *p < 0.05. (C) While the proportions of the different B-cell subpopulations did not change after 12 months of treatment (upper panel), numbers of B mat and B reg cells were decreased (*p < 0.05), and B mem cell numbers showed a clear trend to decrease (lower panel). Data are presented as mean ± SEM for 7 treated patients with MS.
