(Submitter supplied) Transcription factors (TFs) regulate biological events depending on cellular contexts, precise mechanisms for which are elusive. BLIMP1 has been shown to play key roles in many developmental processes, canonically as a transcriptional repressor that targets to proximities of promoters. Here, we systematically and quantitatively characterized genomic binding patterns of BLIMP1 across four distinct, developing cell types; photoreceptor precursors, embryonic intestinal epithelium, plasmablasts, and primordial germ cells (PGCs). more...

(Submitter supplied) Specification of germ cell fate is fundamental in development. With a highly representative single-cell microarray and rigorous quantitative-PCR analysis, we defined the genome-wide transcription dynamics that create primordial germ cells (PGCs) from the epiblast, a process that exclusively segregates them from their somatic neighbors. We also analyzed the effect of the loss of Blimp1, a key transcriptional regulator, on these dynamics. more...

(Submitter supplied) The goal of this study was to profile Blimp1 binding in E18.5 small intestine using a Blimp-1-eGFP knock-in allele, and to compare Blimp-1-eGFP genomic binding with Irf-1 genomic binding in normal small intestine. Changes in Irf-1 binding between wild type and Prdm1/Blimp-1 mutant small intestine were also assessed.

(Submitter supplied) The transcription factor Blimp1 is not only an essential regulator of plasma cells, but also a risk factor for the development of autoimmune disease. Here, we demonstrate that the mouse Prdm1 (Blimp1) gene was partially activated at the chromatin and transcription level in early B cell development, although mature Prdm1 mRNA did not accumulate due to posttranscriptional regulation. By analyzing a mouse model that facilitated ectopic Blimp1 protein expression throughout B lymphopoiesis, we could demonstrate that Blimp1 impaired B cell development by interfering with the B cell gene expression program, while leading to an increased abundance of plasma cells by promoting premature plasmablast differentiation of immature and mature B cells. more...

(Submitter supplied) Plasma cell differentiation involves coordinated changes in gene expression and functional properties of B cells. Here, we study the role of Mzb1, a Grp94 co-chaperone that is expressed in marginal zone (MZ) B cells and during the terminal differentiation of B cells to antibody-secreting cells (ASCs). By analyzing Mzb1 -/- Prdm1 +/gfp mice, we find that Mzb1 is specifically required for the differentiation and function of ASCs in a T cell-independent immune response. more...

(Submitter supplied) To identify candidate Blimp1 target genes in maternal decidua we performed GFP antibody ChIP-seq analysis of E6.5 decidua from homozygous female EGFP-BLIMP1 mice that express an endogenous N-terminal EGFP-tagged Blimp1 protein (Mitani et al., 2017).

(Submitter supplied) Antibody secretion by plasma cells provides acute and long-term protection against pathogens. The high secretion potential of plasma cells depends on the unfolded protein response, which is controlled by the transcription factor Xbp1. Here, we analyzed the Xbp1-dependent gene expression program of plasma cells and identified Bhlha15 (Mist1) as the most strongly activated Xbp1 target gene. As Mist1 plays an important role in other secretory cell types, we analyzed in detail the phenotype of Mist1-deficient plasma cells in Cd23-Cre Bhlha15(fl/fl) mice under steady-state condition or upon NP-KLH immunization. more...

(Submitter supplied) Germ cells ensure reproduction and heredity in metazoans. Primordial germ cells (PGCs) in mice are induced in pluripotent epiblasts by BMP4 and WNT3, yet their mechanism of action remains unclear. Here, using in vitro PGC specification system, we show that WNT3 induces many transcription factors associated with mesoderm in epiblast-like cells (EpiLCs) through b-CATENIN. Among these, T (BRACHYURY), a classical and conserved mesodermal factor, was essential for robust activation of Blimp1 and Prdm14, two of the germline determinants. more...

(Submitter supplied) In many mammalian species, the intestinal epithelium is immature at birth. During the suckling to weaning transition, the intestine matures. This developmental transition is the result of a genetic program that is intrinsic to the gut and independent of luminal content, but its regulators have not been identified. We investigated the function of the transcriptional repressor Blimp-1 using mice with intestine-specific ablation of Blimp-1. more...
