Memory B cells, when re-exposed to Ag and T cell help, differentiate into Ig-secreting cells (ISC) at the same time as maintaining a residual pool of non-Ig-secreting cells with memory capabilities. To investigate the mechanism underlying this dual process, we followed the fate of human B cells activated in vitro with the T cell-derived signals CD40 ligand (CD40L), IL-2, and IL-10 using CFSE to monitor cell division. A substantial number of ISCs detected by ELISPOT, intracellular Ig staining, and Ig secretion could be generated from memory but not naive B cells. The proportion of ISCs increased with successive cell divisions and was markedly enhanced by IL-10 at each division. Within ISCs, two distinct populations were detected after withdrawal of CD40L. The first had acquired the plasma cell marker CD38 and continued to proliferate despite the absence of CD40L. In contrast, the second population remained CD38-, ceased dividing, and underwent rapid apoptosis. The former most likely represent the immediate precursors of long-lived plasma cells, which preferentially home to the bone marrow in vivo, whereas the latter contain short-lived ISCs responsible for the initial Ab response to stimulation with Ag and T cell help. Taken together, the results point to a division-based mechanism responsible not only for regulating differentiation of short- and long-lived ISCs from memory B cells, but for preserving the memory B cell pool for reactivation upon subsequent Ag exposure.
