Figure Lengend Snippet: Figure 3. Expansion of T-bet+ CD11c+ B cells in diet-induced obesity depends on iNKT cells (A) Flow cytometry of lymphocytes from WT or Cd1d1/ mice fed the NCD or HFD, presented with the t-SNE algorithm. See also Figure S4. Color in top row cell maps indicates expression of CD19: blue (low) to red (high). Second row cell maps indicate subgating of B cell cluster 1 (blue) and 2 (red). Histograms show expression of T-bet (third row) and CD11c (bottom row) by clusters identified in t-SNE maps: B cell cluster 1 (blue) and 2 (red). (B–D) Representative flow cytometry of splenic (B) and quantification of WAT and splenic (C and D) T-bet+ CD11c+ cell frequency of total B cells. WT NCD (white) and HFD (black) or Cd1d1/ NCD (light blue) and HFD (dark blue). (E) Flow cytometric quantification of numbers of NK1.1+ iNKT cells in WAT from WT mice fed an NCD (gray) or HFD (red). (F and G) ELISA measure of serum IgG1 (F), IgG2c (G), and IgM (H) antibodies from WT or Cd1d1/ mice fed the NCD or HFD. There is a correlation between frequency of splenic T-bet+ CD11c+ B cells and IgG1 (F), IgG2c (G), and IgM (H), assessed by flow cytometry and ELISA, respectively. WT NCD (white) and HFD (black) or Cd1d1/ NCD (light blue) and HFD (dark blue). Dots represent individual mice. Data pooled from 7 (A–D), 2 (E), or 3 (F and G) experiments with at least 3 mice/group. Mean ± SEM; two-way ANOVA (B and C) or Student’s t test and Student’s paired t test (D–F). Lines indicate linear regression trend with coefficient of determination (r2); *p < 0.05, **p < 0.01, ***p < 0.001.
