Abstract

The transcription factor BATF controls the differentiation of interleukin 17 (IL-17)-producing helper T cells (TH 17 cells) by regulating expression of the transcription factor ROR3t itself and ROR3t target genes such as Il17. Here we report the mechanism by which BATF controls in vivo class-switch recombination (CSR). In T cells, BATF directly controlled expression of the transcription factors Bcl-6 and c-Maf, both of which are needed for development of follicular helper T cells (T FH cells). Restoring T FH cell activity to Batf T cells in vivo required coexpression of Bcl-6 and c-Maf. In B cells, BATF directly controlled the expression of both activation-induced cytidine deaminase (AID) and of germline transcripts of the intervening heavy-chain region and constant heavy-chain region (I H-C H). Thus, BATF functions at multiple hierarchical levels in two cell types to globally regulate switched antibody responses in vivo.
