title: BLIMP1 guides the fate of effector B and T cells.
abstract: B-lymphocyte-induced maturation protein 1 (BLIMP1) is a transcriptional repressor, and its importance in controlling the terminal differentiation of antibody-secreting cells (ASCs) is well established. However, as we discuss in this Progress article, it has now become evident that the ASC programme consists of a discrete BLIMP1-independent initiation phase, followed by a second step in which BLIMP1 is absolutely required for the differentiation of fully mature ASCs. In addition, an important role for BLIMP1 in maintaining the homeostasis of effector T cells is emerging, suggesting intriguing parallels between the control of effector-cell fates in both B and T cells.
