Witryna1 lis 2024 · Pre-B cells subsequently undergo Ig light chain rearrangement and become immature B cells that express a functional BCR. Immature B cells exit the bone marrow and reach the spleen, where they complete their development into mature B cells (20, 21). B cells colonize the thymus very early in life during fetal development. WitrynaTransitional 3 (T3) B cells, once thought to be part of the linear development from immature to mature B cells, are now thought to represent primarily self-reactive …
WitrynaRegulatory B cells. B cells have a positive role in priming adaptive CD4+ T cells, but not CD8+ T cells. The magnitude of CD4+ T-cell responses is reduced upon pathogen challenge in B-cell deficient or depleted mice. B cells are also able to dampen T-cell driven immune responses, giving rise to the concept of regulatory B cells (Bregs).
