Maf is a transcription factor regulating pivotal biological processes in multiple immune cells, but its B-cell-intrinsic role is not fully known. Here authors show that genomic deletion of Maf in the B cell lineage does not disturb the sequence of developmental stages, however, removes an important inhibitory step to restrict the early steps of germinal centre B cell and extrafollicular plasmablast population expansion.
