The role of B cells in the development of CD4(+) regulatory T cells has been
emphasized recently. Our previous studies have demonstrated that the
antigen-presenting splenic B cells converted naïve CD4(+)CD25(-) T cells into
CD4(+)CD25(+)Foxp3(-) T cells without additional cytokines or chemicals with
regulatory activity and that referred to as Treg-of-B cells. The present study
further showed that Treg-of-B cells increased the IL-10-producing population, and
the expression of c-Maf, inducible T-cell co-stimulator (ICOS) as well as
cytotoxic T-lymphocyte-associated protein 4 (CTLA4) after repeated stimulation of
B cells in a cell-cell contact-dependent manner. Long-term cultured Treg-of-B
cells exerted IL-10 and CTLA4-mediated antigen-specific suppressive activity;
moreover, the single antigen-specific Treg-of-B cells inhibited in a
non-antigen-specific fashion. In conclusion, these results suggest that repeated
stimulation of B cells induced IL-10-producing CD4(+)Foxp3(-) regulatory T cells
in a contact-dependent manner and these Treg-of-B cells possess IL-10 and
CTLA4-dependent suppressive function.
