title: MicroRNA-155 function in B Cells.
abstract: Vigorito et al. (2007) report (in this issue of Immunity) that B cells require microRNA (miR)-155 for normal production of isotype-switched, high-affinity antibodies and for a memory response. They identify transcriptional regulator Pu.1 as a functionally important target of miR-155 in B cells.
