RNAseq of germinal center B cells from Blimp-1-GFP reporter mice with an ablatable TfH compartment.

Project description:RNAseq of germinal center B cells (B220+IgDlowCD95+GL7+) with different Blimp-1-GFP reporter level in the presence of TfH cells or 72 hr after their depletion. Sorted germinal center populations were defined by their expression of Blimp-1-GFP reporter and the cell surface marker CD138. Analysed mice were bone marrow chimeras generated with a bone marrow mixture from CD4-cre+ Rosa26-loxP-stp-loxP-DTR Blimp-1GFP/+ (10%) and Rag1-/- OTII (90%) mice. In these mice TfH cells can be depleted by the injection of human diphteria toxin (DT).

RNAseq of germinal center B cells from Blimp-1-GFP reporter mice

Project description:RNAseq of germinal center B cells with different Blimp-1-GFP reporter level. Sorted germinal center populations were defined by their expression of Blimp-1-GFP reporter and the cell surface marker CD138 before they were further split into dark zone or light zone / dark zone like or light zone like cells based on their expression of the surface marker CXCR4 and CD83. We used RNAseq to find genes differentially regulated in various Blimp-1-GFP expressing germinal center populations from the spleen at day 10 after intraperitoneal immunisation with sheep red blood cells.

Transcriptome analysis of early differentiating Tfh vs Th1 cells

Project description:Comparison of transcriptome between early Tfh vs. early Th1 cells Blimp-1-YFP LCMV gp specific TCRtg Smarta cells were transferred into B6 mice, which were then infected with LCMV Armstrong. On day 3 after infection, splenocytes were stained to sort Blimp-1-YFP+IL-2Ra+ Th1 cells or Blimp-1-YFP-IL-2Ra- Tfh cells for RNAseq analysis. Contributor: LIAI RNAi center (LIAI)

Single cell RNA-seq of sorted Tfh cells from C57BL/6 Foxp3-GFP mice immunized with OVA-IFA and OVA-CpG

Project description:The aim of the project was the identification of the transcriptional signature of Tfh cells that emerge following immunization with different adjuvants. For this purpose C57Bl/6 mice, bearing a Foxp3-GFP reporter system, were immunized with OVA-IFA or OVA-CpG. At day 11 post-immunization, Foxp3 negative Tfh cells were FACS-sorted from the draining lymph nodes and processed for single cell RNA sequencing.

miRNA expression in Blimp-1-deficient dendritic cells

Project description:Expression of Blimp-1 was specifically deleted in dendritic cells (DCs) by breeding Blimp-1 flox and CD11c-CRE mice. MiRNA expression was evaluated and compared from DCs, CD4+ T cells and total B cells from spleens of control and Blimp-1 KO mice. Age-matched (6-10 weeks old) female mice from control and Blimp-1 KO mice were sacrificed and spleens were collected. CD11chi/MHCIIhi DCs, CD4+TCRb+ T cells and B220+ B cells were sorted by FACSaria. MiRNA was measured from the total RNA preparation.

Analysis of Blimp-1 and Irf-1 genomic binding in wild type and Prdm1/Blimp-1 mutant embryonic gut

Project description: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. ChIP-seq was performed for Blimp-1-eGFP in duplicate in E18.5 small intestine expressing the fusion protein using anti-GFP antibody. As a negative control a single anti-GFP ChIP was also performed in wild type small intestine. ChIP-seq for Irf-1 was performed in duplicate in both wild type and Prdm1/Blimp-1 mutant E18.5 small intestine using an anti-Irf-1 antibody. Duplicate IgG ChIP control in wild types was performed as a negative control. All samples had an associated input chromatin sample sequenced.

Expression Data from in vivo Tfh vs GC Tfh vs non-Tfh

Project description:CD4 T cell help is critical for both the generation and maintenance of germinal centers, and T follicular helper (TFH) cells are the CD4 T cell subset required for this process. SAP (SH2D1A) expression in CD4 T cells is essential for germinal center development. However, SAP-deficient mice have only a moderate defect in TFH differentiation as defined by common TFH surface markers. CXCR5+ TFH cells are found within the germinal center as well as along the boundary regions of T/B cell zones. Here we show that germinal center associated T cells (GC TFH) can be identified by their co-expression of CXCR5 and the GL7 epitope, allowing for phenotypic and functional analysis of TFH and GC TFH populations. Here we show GC TFH are a functionally discrete subset of further polarized TFH cells, with enhanced B cell help capacity and a specialized ability to produce IL-4 in a TH2-independent manner. Strikingly, SAP-deficient mice have an absence of the GC TFH subset and SAP- TFH are defective in IL-4 and IL-21 production. We further demonstrate that SLAM (Slamf1, CD150), a surface receptor that utilizes SAP signaling, is specifically required for IL-4 production by GC TFH. GC TFH cells require IL-4 and IL-21 production for optimal help to B cells. These data illustrate complexities of SAP-dependent SLAM family receptor signaling, revealing a prominent role for SLAM receptor ligation in IL-4 production by germinal center CD4 T cells but not in TFH and GC TFH differentiation. Analysis of in vivo polyclonal GC Tfh vs Tfh vs Non-Tfh eight days after LCMV viral infection. Analysis of in vivo follicular helper CD4 T cells (CXCR5high GL7low), versus germinal center follicular helper CD4 T cells (CXCR5hi GL7hi), versus non-follicular helper CD4 T cells (CXCR5low) eight days after viral infection.
