The basis of a humoral response of the immune system to antigen is the proliferation of antigen-specific B lymphocytes and their maturation to antibody(immunoglobulin, Ig)-secreting cells (1). Antigen selects from the repertoire of resting B cells, each expressing one of the diverse sets of variable regions of heavy and light chains of Ig on their surface (2-5). Upon stimulation, in vivo or in vitro, B cells will divide every 20 hr at 37°C, in vitro for 5-15 divisions (6). A single B-cell clone retains remarkable synchrony for several divisions (6,7). When B cells mature they not only increase their rate of Ig synthesis and begin actively to secrete Ig, they also switch the class of heavy chains that carry the variable regions involved in antigen recog nition. A single dividing clone of B cells may switch at any division (8). Switching occurs in individual cells of the clone. Furthermore, a high rate of somatic mutations occurs in Ig genes during the process of clonal B-cell expansion that may alter the specificity of antigen recognition (9-12). Within an expanding clone of B cells, some cells may return to rest and remain in the immune system as long-lived memory cells (13). In vitro such memory cells have not yet been generated unambiguously. In vitro studies with polyclonally activated murine B cells have, however, given some insight into the kinetics of a B-cell response and the qualitative and quantitative changes in the expression of Ig genes that occur during this process (Figure 1) (14).
