Witryna17 sty 2024 · B cells are lymphocytes that play a large role in the humoral immune response (as opposed to the cell-mediated immune response, which is governed by T cells).

Immature B cells are produced in the bone marrow of most mammals. Rabbits are an exception; their B cells develop in the appendix-sacculus rotundus.After reaching the IgM+ immature stage in the bone marrow, these immature B cells migrate to the spleen, where they are called transitional B cells, and some of … 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. in the between movie online subtitrat
