Human tonsillar subepithelial B cells, which are a marginal zone-equivalent B cell subset, respond readily to T-independent type 2 antigens, but not to polyclonal B cell activators in vitro. In this study, subepithelial (SE) B cells were induced to proliferate and mature into plasma cells when co-cultured with activated T cells. The response of SE B cells was not observed when co-cultures were carried out in transwell chambers or in the presence of blocking anti-LFA-1 antibodies, demonstrating the need for a close T-B cell interaction. The presence of soluble CD40 also prevented the B cell response in vitro suggesting a pivotal role of CD40-CD40 ligand interactions. The data are discussed in terms of the T cell dependence of marginal zone (MZ) B cell response and the possible existence of various MZ B cell subsets.
