Article Title: Tumor-Associated Neutrophils Drive B-cell Recruitment and Their Differentiation to Plasma Cells

doi: 10.1158/2326-6066.cir-20-0839

Figure Lengend Snippet: Figure 5. TANs drive B-cell differentiation independently of T cells. A, Quantification of CD138 expression on splenic B220þ cells following various culture conditions—when cultured alone (B), with T cells (B þ T, ratio 1:1), with TANs (B þ TAN, ratio 1:1), with TAN and T cells (B þ TAN þ T, ratio 1:1:1), with T cells but no contact allowed with TANs (B þT//TAN,ratio 1:1:1), or TANs cocultured with T cells but no contact allowed with B cells (B//T þTAN, ratio 1:1:1). Data represent the mean SEM (n ¼ 6–9; , P < 0.001; n.s., not significant). Groups were compared using one-way ANOVA. B, Representative flow plots displaying CD138 expression out of total B220þ population in the different coculture conditions. C, Quantification of IgG release to the media following overnight coculture of isolated splenic B220þ

Article Snippet: Isotype control antibodies were as follows: APCconjugated rat IgG2a (clone 2A3; Biogems), FITC-conjugated rat IgG2b (clone RTK4530; BioLegend), BGViolet450 rat IgG2a (clone 2A3, Biogems), PE-conjugated rat IgG2a (clone 2A3, Biogems).

Figure Lengend Snippet: Figure 6. TANs express membranal BAFF, but not membranal APRIL, and mediate B-cell IgG production in a BAFF-R–dependent manner. A and B, Expression of membranal BAFF and APRIL in TANs within the whole tumor (A) and following TANs' isolation from the tumors (B). Representative histograms showing BAFF and APRIL expression in TANs (gated as total Ly6Gþ population) are provided (right plots). C, IgG production by splenic B cells cocultured with TANs (ratio 1:5) in the absence or presence of anti–BAFF-R antibody. Data represent the mean SEM (n ¼ 4; , P < 0.01; , P < 0.001). Groups were compared using one-way ANOVA. D, Quantification of CD138 expression on isolated splenic B220þ cells cultured alone or cocultured with TANs (ratio 1:5), without or with blocking of the three potential BAFF receptors, BAFF-R, TACI, or BCMA. Data represent the mean SEM (n ¼ 4–10; , P < 0.001; n.s., nonsignificant). Groups were compared using one-way ANOVA.
