Abstract

In response to antigenic stimulation, mature B cells interact with follicular helper T cells in specialized structures called germinal centers (GCs), which leads to the development of memory B cells and Ab-secreting plasma cells. The transcription factor IFN regulatory factor 4 (IRF4) is essential for the formation of follicular helper T cells and thus GCs, although whether IRF4 plays a distinct role in GC B cells remains contentious. RNAseq analysis on ex vivo-derived mouse B cell populations showed that Irf4 was lowly expressed in naive B cells, highly expressed in plasma cells, but absent from GC B cells. In this study, we used conditional deletion of Irf4 in mature B cells as well as wil..
