Figure 4.
Constitutive activation of the NLRP3 inflammasome in myeloid cells causes anemia of inflammation through IL-1 signaling. All data were obtained from 2-week old WT or mutant male mice. (A–E) Cell blood counts (n = 4 mice/genotype). WBC, white blood cell counts, RBC, red blood cell counts. (F) Bone marrow cells (n = 4 mice/genotype) were stained with isotype control (data not shown) or with antibodies against CD11b and Ter119. Representative flow cytometry dot plots of CD11b+ myeloid cells or Ter119+ erythrocytes from each genotype are shown. (G) The percentage of Ter119+ erythrocytes in bone marrow cells. Data are expressed as mean ± SEM. *P < 0.05; **P < 0.005. (H) Body weight. (I) Spleen weight. (J) Percent of spleen weight (spleen weight was normalized to body weight). Quantitative data (H–J) were obtained from 5–6 mice/genotype and expressed as the mean ± SEM. *P < 0.05; **P < 0.005. (K) Body weight. (L) Spleen weight. (M) Percent of spleen weight. Quantitative data (K–M) were obtained from 3–5 mice/genotype and expressed as the mean ± SEM. **P < 0.005. NS, not significant.
