Supplementary Figure 1: Phenotype of stimulated human peripheral blood B cells in presence or not of HIV-1 gp120.

Surface expression of B cell markers, gated on freshly isolated B cells from PBMCs. a) Flow cytometry histograms show B cells at day 0 (black) versus α -IgM + CpG stimulated B cells at day 4 (red). b) B cells at day 0 (black) versus α -IgM + CpG + R66M gp120 stimulated B cells at day 4 (blue).
