WitrynaTransitional B cells that survive selection against autoreactivity develop eventually into naive B cells. Given the fact that only a small fraction of immature B cells survive the transition to the mature naive stage, the transitional B cell compartment is widely believed to represent a key negative selection checkpoint for autoreactive B cells.
