Seventy percent of peripheral immature conventional (B2) B cells fail to develop into mature B cells. The nature of this cell loss has not been characterized; the process that governs which immature B cells develop into long-lived peripheral B cells could be either stochastic or selective. Here, we demonstrate that …

B-cell development in the gut Nature

B cells development starts in the bone marrow (BM), from a hematopoietic stem cell precursor, and undergoes an ordered series of differentiation steps to ultimately generate mature naïve B cells in the peripheral blood (1). As development progresses, the B cell receptor (BCR) is generated and adjusted to ensure … Zobacz więcej The lack of difference between the heavy chain repertoire in pre-B and immature B cells implies that there is very little selective pressure at this developmental stage, which is in agreement with current thinking on the … Zobacz więcej Witryna1 lut 2002 · These cells leave the BM and further develop into mature cells. Of the ~2×10 7 IgM + B cells which develop in the murine BM daily, only ~10% exit to the periphery. Of these émigrés, a larger proportion progresses to the immature B cell pool (5, 6).
