Transcriptional changes upon Jagn1 loss in LPS-stimulated plasmablasts.

ABSTRACT: We report that Jagn1-deficiency is associated with alterations in the ER of antibody-producing cells and decreased immunoglobulin levels. By doing QuantSeq of FACS-sorted CD22-CD138+ plasmablasts, we found several differentially expressed genes in Jagn1DB knock-out mice.

RNA-seq of primary mouse B cell progenitor populations after activation with LPS

Project description:Naive resting B-cells were purified from bone marrow from C57BL/6 mice using flow cytometry sorting. Naive B cells were activated with LPS and harvested 3 hours, 10 hours or 33 hours after the LPS treatment. Expanded activated B cells (CD22+ CD138-) and plasmablasts (CD22- CD138+) were also harvested on day 4 post-stimulation.

CTCF binding in B cells and Plasmablasts

Project description:The mammalian CCCTC-binding factor (CTCF) regulates gene expression through the formation of higher order chromatin structures. Recent evidence has implicated a role for CTCF in regulating gene expression in the human MHCII locus. To investigate the role of CTCF in murine MHCII gene expression we mapped CTCF binding sites in B cells (MHCII+ cells) and Plasmablasts which are differentiated B cells that have silenced MHCII gene expression. These observations lead to the identification of differential CTCF binding during differentiation in these cell types and suggest mechanims of MHCII gene regulation.

Transcriptomic and V(D)J profiling at the single cell level of plasmablasts from lymph nodes of mice immunized with bMOG protein

Project description:Autoantibodies contribute to many autoimmune diseases, yet there is no therapy to neutralize them selectively. A popular mouse model, experimental autoimmune encephalomyelitis (EAE), could serve to develop such a therapy, provided we can better understand the nature and importance of the autoantibodies involved. In this study, we analyzed autoantibody-secreting extrafollicular plasmablasts in mice with EAE induced by immunization with a mutated myelin oligodendrocyte glycoprotein (MOG) antigen called bMOG. These CD138+ cells were enriched from lymph nodes at day 8 post-immunization and analyzed by single-cell RNA sequencing using 10× Genomics technologies. Here we provide the raw and processed data obtained from the gene expression (GEX) and VDJ cDNA libraries.

LSD1 regulates the plasmablast transcriptome

Project description:To understand the role of LSD1 in B cell differentiation, mice with B cell conditional deletion of LSD1 were intravenously inoculated with LPS. After 3 days, B220+GL7-CD138- naïve B cells and CD138+ plasmablasts were FACS-sorted from the spleens and RNA-seq was performed to identify LSD1-target regulated genes.

EZH2 is required for gene repression in Plasmablasts

Project description:To understand the role of EZH2 in Plasmablast function EZH2 was inducibly deleted using tamoxifen and B cells stimulated to differentiate with LPS in vivo. After 3 days, CD138+ cells were enriched from the spleens and RNA-seq was performed to identify the genes targeted by EZH2 for repression.

Mapping of 5-hydroxymethylcytosine by selective chemical labeling (SCL-seq) in human naive B cells and in vitro differentiated plasmablasts (P1 cells) [HTS]

Project description:We report the genome-wide mapping of 5hmC in naive B cells and in vitro differentiated plasmablasts (P1 cells). In addition, H3K4me1 and H3K27ac histne marks were mapped in in vitro differentiated plasmablasts from two healthy donors (BN358 and BN369) by ChIP-seq. Genomic DNA from human primary cells was extracted and submitted to the SCL protocol using the Hydroxymethyl Collector kit from Active Motif. After sequencing on an Illumina HiSeq 2000, reads were mapped to the human hg19 genome. H3K4me1 and H3K27ac were mapped in in vitro differentiated plasmablasts (P1 cells) by ChIP-seq.

Plasmablasts and germinal center founder cells developing in vivo

Project description:A range of cellular interactions and cytokines influence immunoglobulin class switch recombination (CSR), which occurs both in extrafollicular antibody responses and germinal centers. This study addresses where CSR occurs during extrafollicular responses, allowing identification of the cellular interactions and cytokine-producing cells that influence CSR in vivo. The response in mice of B cells specific for 4-hydroxy-3-nitrophenyl-acetyl (NP) to NP-Ficoll was analyzed. Immunohistology and flow cytometry confirm responding NP-binding cells move to the outer T zone of the spleen and start dividing there on the second day. During the third day they move either to follicles as germinal center founding cells, or extrafollicular foci as plasmablasts. Analysis of expression of AID, Bcl-6 and Blimp-1 mRNA in single NP-binding cells indicates a proportion of T zone B blasts express AID transiently without Bcl-6 and these cells are shown to undergo CSR. By contrast Blimp-1+ cells emerging on the third day and were universally AID- and hence unable to initiate CSR. Bcl-6 mRNA without protein, expressed by 40% of naïve NP-binding cells, is rapidly downregulated. Bcl-6 and AID are coexpressed by germinal centre founding cells only on moving to follicles during the third day after immunization. Keywords: TaqMan Low Density Array
