Fig. 5. The peripheral ABC phenotype is affected by EBV infection and MS status.

Fig. 5.

PBMCs were collected from three EBV-seronegative healthy females (EBV HD, black circles), four EBV-seropositive healthy females (EBV+ HD, green triangles), and five females with RRMS that are all EBV seropositive (EBV+ MS, orange diamonds). PBMCs were processed for flow cytometry immediately following isolation. (A) Representative gating strategy for ABCs (CD19+CD20+CD11c+CD21) from human PBMCs. (B) Proportion of ABCs (CD11c+CD21) among previously activated B cells (CD19+CD20+IgD). (C to E) Representative samples and percent of ABCs (CD19+CD20+CD11c+CD21) positive for (C) Fas, (D) PD1, and (E) CD27. Data for CD27- and PD1-stained samples are fewer (n = 2 to 4 donors per group) due to later addition of these markers following initial findings. Data are presented as means ± SEM, analyzed by one-way ANOVA with multiple comparisons; **P < 0.01 and *P < 0.05.
