Abstract excerpt
Developing B cells undergo selection at multiple checkpoints to eliminate autoreactive clones. We analyzed B cell kinetics in the NOD mouse to establish whether these checkpoints are intact. Our results show that although bone marrow production is normal in NOD mice, transitional (TR) B cell production collapses at 3 wk of age, reflecting a lack of successful immature B cell migration to the periphery. This...
