(A , B) Representative cytometry plots (A) and quantification (B) of intracellular and nuclear localization of c‐Rel and phosphorylated p65 (Ser536) in sorted IgM+ and IgG1+ Tet2 ‐WT and Tet2 ‐KO B cells at D4 of the in vitro GC model ( n = 3). (C , D) Representative cytometry plots (C) and quantification (D) of intracellular and nuclear localization of c‐Rel and phosphorylated p65 (Ser536) in sorted IgG1+ Tet2 ‐WT and Tet2 ‐KO B cells at D8 of the in vitro GC model ( n = 3). (E) Expansion factor compared to empty MSCV condition between D11 and D14 and quantification of MFI of IgG1 in IgG1+ iGCB (GFP+ CD19+ CD138− Fas+ GL7+ IgG1+) at D14 of the iGCB transduction model, after transduction of Tet2 ‐KO B‐cells by an empty MSCV, a MSCV containing shRNA Rel 908, or a MSCV containing shRNA Rel 1869 ( n = 3). For (B , D) , P values were calculated using an unpaired two‐tailed t ‐test. For (E) , P values were calculated using a paired RM one‐way ANOVA test. * P < 0.05, ** P < 0.01, *** P < 0.001 and ns, not significant in all experiments. ANOVA, analysis of variance; GC, germinal center; iGCB, induced germinal center B‐cell; MFI, mean fluorescence intensity; MSCV, murine stem cell virus.

    Article Snippet: At Day 0, splenic murine naïve B‐cells from a Tet2 ‐KO mouse were isolated from 3 to 4‐month‐old mice using the mouse B‐cell isolation kit (CD43 (Ly‐48) MicroBeads; Miltenyi Biotec) following the manufacturer's instructions (yield >90% CD19+ B220+).
