(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) 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) 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) The activated B-cell (ABC) to plasmablast transition is the cusp of antibody secreting cell (ASC) differentiation but is incompletely defined. We apply expression time-courses, parsimonious gene correlation network analysis, and ChIP-seq to explore this in human cells. The transition initiates with input signal loss leading within hours from cell growth dominant programs to enhanced proliferation, accompanied from 24h by ER-stress response, secretory optimization and upregulation of ASC features. more...

(Submitter supplied) Integrin b1-deficient mice have a defect in the differentiation of MZ B cells and plasma cells.We performed a genome-wide transcriptome analysis of ex vivo-sorted Fo B, transitional B and MZ B cells of in Integrin b1 KO and Integrin b1 WT mice. We also performed invitro culture of CD93+ (AA4.1+) transitional B cells to study the role of PI3 Kinase signalling.

(Submitter supplied) Differentiation of B cells into antibody secreting cells (ASCs), plasmablasts and plasma cells, is regulated by a network of transcription factors. Within this network factors including PAX5 and BCL6 prevent ASC differentiation and maintain the B cell phenotype whereas BLIMP-1 and high IRF4 expression promote plasmacytic differentiation. BLIMP-1 is thought to induce immunoglobulin secretion. While IRF4 is needed for the survival of ASCs, its role in the regulation of antibody secretion has been controversial. more...

(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) Upon encounter with antigen, B cells undergo a sequential process of differentiation to become antibody-secreting plasma cells. While the key drivers of differentiation have been identified, research has been limited by the lack of in vitro models recapitulating the full process for murine B cells. Here we describe methodology using BCR or TLR ligation to obtain plasma cells that are phenotypically mature, have exited cell cycle and express a gene signature concordant with long-lived plasma cells. more...
