B-1CDPs are one of the components of the peritoneal macrophage population after LPS stimulation.

<p>A) Absolute number of peritoneal B-1 cells (CD19⁺CD23⁻CD11b⁺) detected in BALB/<i>Xid</i> mice submitted to the specified treatment. ** p<0.01 and ***p<0.001 when the indicated groups are compared with the non-marked groups. p<0.001 when the two last groups are compared. B) Absolute number of peritoneal macrophages (CD19⁻CD11b⁺F4/80⁺) detected in BALB/<i>Xid</i> mice submitted to the specified treatment. ** p<0.01 and ***p<0.001 when the indicated groups are compared with the non-marked groups. C) Absolute number of macrophages (CD19⁻CD11b⁺F4/80⁺) and the number of B-1CDPs (CFSE⁺ cells) detected in this population from BALB/<i>Xid</i> mice submitted to the specified treatment. **p<0.01 and ****p<0.001 when the CFSE⁺ cell number of the indicated groups are compared with all other groups. The results are representative of two independent experiments using 4 or 5 mice per group per experiment.
