Changes in Single and Dual BCR B1 and B2 Cells in the Peritoneum. (A) Categorization of peritoneal B cells into B1 and B2 subsets. (B) Mapping of various BCR combinations within B1 and B2 subsets. (C) Distribution of single and dual BCR statuses in B1 and B2 cells. (D) Comparison of B1 and B2 cell numbers in neonatal, 10-week-old, and 15-month-old mice. (E) Proportion of dual BCR B1 and B2 cells at different ages. (F) Increase in H + κ1 + κ2 B1 cells in 15-month-old mice. (G) Differential gene expression analysis in dual BCR B cells compared to single BCR B cells
