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.
B淋巴细胞诱导成熟蛋白1(BLIMP1)是一种转录抑制因子,其在控制抗体分泌细胞(ASC)终末分化中的重要性已得到充分证实。然而,正如我们在这篇进展文章中所讨论的,现在已经很明显,ASC程序包括一个独立于BLIMP1的起始阶段,随后是第二步,在这一步中,BLIMP1对于完全成熟的ASC的分化是绝对必需的。此外,BLIMP1在维持效应T细胞稳态中的重要作用正在显现,这表明B细胞和T细胞中效应细胞命运控制之间存在有趣的相似之处。
