Expression data from murine eGFP+ relfl/flCg1-Cre and eGFP-Cg1-Cre splenic germinal center B cells purified by fluorescent activated cell sorting.

Project description:Gene expression profiling of murine eGFP+ relfl/flCg1-Cre and eGFP− Cg1-Cre splenic germinal center B cells identifies genes regulated by the transcription factor c-REL in germinal center B cells. Germinal center B cells from 12-week old relfl/flCg1-Cre and Cg1-Cre littermate mice immunized with sheep red blood cells (SRBC) were isolated at day 7 after immunization by flow cytometric sorting from splenic mononuclear cells. RNA was isolated. Following a cDNA amplification step, labeled cRNA was hybridized to microarrays and genes specifically expressed in eGFP+ relfl/flCg1-Cre and eGFP− Cg1-Cre samples were identified by supervised analysis.

Transcriptome of Prmt5-deficient and control mouse activated B cells

Project description:Quiescent splenic B cells purified from Cg1-cre Prmt5F/F cells and Cg1-cre control mice. Resting B cells were plated on feeder cells expressing CD40L and BAFF and supplemented with IL-4 for activation. Four days later, the resulting activated germinal center-like B cells were purified and RNA extracted and processed for HiSeq. Four independent samples of each genotype were processed and analyzed.

Single-cell gene expression of germinal center B cells from CXCL12-conditionally deficient and –sufficient mice

Project description:The chemokines CXCL13 and CXCL12 are reported to be important for the germinal center reaction. Since CXCL12-deficient mice are embryonically lethal, here we took advantage of the Cxcl13-Cre/TdTomato mouse models to genetically ablate CXCL12 from B cell-interacting reticular cells and examine the molecular consequence on germinal center B cells. Spatial segregation of follicular dendritic cells, germinal center B cells and follicular helper T cells is impaired in Cxcl13-Cre/TdTomato Cxcl12fl/fl mice. Single cell transcriptomic analysis revealed that all germinal center B cell subsets (corresponding to distinct stages of the germinal center response) are present in draining lymph nodes of immunized CXCL12-conditionally deficient mice. While most transcriptional regulators of the germinal center response are unperturbed by the genetic perturbation of CXCL12, Bach2 levels were elevated in germinal center B cells from lymph nodes of Cxcl12fl/fl mice. Moreover, single cell B cell receptor sequencing revealed that germinal center B cells in Cxcl13-Cre/TdTomato Cxcl12fl/fl mice harbour a lower mutational burden when compared to germinal center B cells isolated from immunized control mice. Gene expression profiles were validated by flow cytometry and suggest that the provision of CXCL12 by reticular cells governs efficient germinal center responses.

YY1 plays an essential role at all stages of B cell differentiation [ChIP-seq]

Project description:YY1 is a ubiquitously expressed transcription factor that has been demonstrated to be essential for pro-B cell development. However, the role of YY1 in other B cell populations has never been investigated. It has been proposed that YY1 is a key regulator for the germinal center B cell program since the YY1 motif was present in much higher frequency in germinal center B cell signature genes than signature genes of other B cell subsets. Indeed, in accord with this prediction, we demonstrated that deletion of YY1 by Cg1-Cre completely prevented differentiation of naïve B cells into germinal center B cells and plasma cells after antigen stimulation. To determine if YY1 was also required for the differentiation of other B cell populations, we deleted YY1 with CD19-Cre and found that all peripheral B cell subsets including B1 B cells require YY1 for their differentiation. By deleting YY1 acutely with ER-Cre, we demonstrated that all B cell subsets require YY1 for their maintenance. ChIP-seq shows that YY1 predominantly binds to promoters, and pathway analysis of the genes which bind YY1 show that they are enriched in ribosomal functions, mitochondrial functions such as bioenergetics, and functions related to transcription, such as mRNA splicing, metabolism of RNA. By RNA-seq analysis of differentially expressed genes, we demonstrated that YY1 normally activates genes involved in mitochondrial bioenergetics, while it normally downregulates genes involved in transcription, mRNA splicing, NF-kB signaling pathways, AP-1 transcription factor network, chromatin remodeling, cytokine signaling pathways, cell adhesion, cell proliferation and c-Myc targets.
