(A) Gating strategy used to identify myeloid cell populations from the spleen of WT and Hbbth3/+ mice: (i) mature neutrophils (Ly6GhiLy6Cint),(ii) immature myeloid cells (Ly6GintLy6Cint), (iii) resident monocytes (Ly6GnegLy6Cint), and (iv) inflammatory monocytes (Ly6GnegLy6Chi). Representative dot plots from 1 out of 3 independent experiments are shown. (B) Quantification of percentages of mature neutrophils, immature myeloid cells, resident monocytes, and inflammatory monocytes in CD11b+ spleen cells. Individual values and mean ± SD are shown. n = 8–13 mice per group. Statistical analysis was performed by comparing all treatment groups to the Hbbth3/+ vehicle group using 1-way ANOVA with Dunnett’s multiple comparison test. ***P < 0.001.
