Humoral immunity, including antibody switching and somatic hypermutation, is critically regulated by CD4+ T cells. T follicular helper (Tfh) cells have been recently shown to be a distinct T cell subset important in germinal center reations. The transcriptional regulation of Tfh cell development and function has not been well understood. Here, we report that the CCAAT enhancer binding protein alpha (C/EBPα), a basic region/leucine zipper (bzip) transcription factor, is highly expressed in Tfh cells. Cebpa-deficient CD4+ T cells exhibit enhanced IFN-γ expression in vitro and in vivo. T cell-specific Cebpa knockout (KO) mice, though not defective in Tfh cell generation, produce significantly increased levels of IgG2a/b and IgG3 following immunization with a protein antigen. Moreover, C/EBPα binds to the Ifng gene and inhibits T-bet-driven Ifng transcription in a DNA binding-dependent manner. Our study thus demonstrates that C/EBPα restricts IFN-γ expression in T cells to allow proper class switching by B cells.
