The B-cell population responsible for in vitro antigen-mediated proliferation and expansion of the memory B-cell population is a large activated blast. Such cells predominate early after antigen priming and can be regenerated by adjuvant (Bordetella pertussis) stimulation in vivo. Although these cells are proliferating in vivo, additional stimuli are needed for expansion of the memory population in vitro. These triggering requirements include specific antigen (DNP-OVA) and the assistance of adherent accessory cells. Although T cells are present in the culture, their role in the propagation of memory is not completely clear. Using the unrelated antigen, sheep erythrocytes, we have shown that "bystander" T-cell help can mediate differentiation of these memory B-cell blasts to AFC, but it cannot induce expansion of the memory-cell population. However, the fact that the TI-2 antigen DNP-Ficoll is a relatively ineffective inducer of memory-cell propagation (inducing an expanded response which is less than 10% of that induced by the T-cell-dependent antigen, DNP-OVA) suggests that T cells may be involved, possibly via production of B-cell growth factor. Thus, the minimal requirements for triggering the propagation of B-cell memory include (i) a blastogenic signal which can be mediated by adjuvant, (ii) specific antigen, and (iii) adherent accessory-cell help.
