Project description:Conditional IRF8 KO mice (mice with a conditional allele of Irf8 crossed with CD19-Cre mice) showed increased numbers of both Gene expression data spleen marginal zone (MZ) and Gene expression data spleen follicular (FO) B cells compared to control mice. To evaluate gene expression patterns that distinguished FO or MZ B cells derived from conditional KO and control mice, we used Affymetrix GeneChip® Mouse gene 1.0 ST Array.

To evaluate gene expression patterns that distinguished FO or MZ B cells derived from conditional KO and control mice, we used Affymetrix GeneChip® Mouse gene 1.0 ST Array. FACS-sorted MZ and FO B cells from individual mouse were used for RNA extraction and Affyarray hybridization. There were six independent biological replications in each group - six cases of MZ B cells and FO cells in IRF8 conditional KO mice and six cases of MZ B cells and FO cells in control WT mice.

Project description:We compared the clonotypes of IL-10+ and IL-10- B1a, marginal zone and follicular B cells from the spleen of sIgM-/-IL10GFP mouse using 10X single cell RNAseq to analyze potential differences in clonality between IL-10+ and IL-10- B cells.

Project description:To understand the role of LSD1 in splenic B cell development, spleens from mice with B cell conditional deletion of LSD1 were harvested, B220+CD93–GL7–CD23–CD21hiCD1d+ marginal zone B cells and B220+CD93–GL7–CD23+CD21midCD1d– follicular B cells were FACS-sorted, and ATAC-seq was performed to identify LSD1-target regulated chromatin.

Project description:Gene expression analysis of splenic follicular B cells and marginal zone B cells from B6 and CD19:KLF3 transgenic mice Comparing KLF3-transgenic and non-transgenic follicular B cells by RNA-microarray revealed that KLF3 regulates a subset of genes that was similarly up-/downregulated upon normal MZ B cell differentiation. Indeed, KLF3 expression overcame the lack of MZ B cells caused by different genetic alterations, such as CD19-deficiency or blockade of B-cell activating factor (BAFF)-receptor signaling, indicating that KLF3 may complement alternative NF-κB signaling. Thus, KLF3 is a driving force towards MZ B cell maturation. RNA of splenic follicular B cells and marginal zone B cells were obtained from 4 different mice per group (B6 and CD19:KLF3 mice). 16 samples = 8 individual mice x 2 B cell subsets.

Project description:The mature peripheral B cell compartment consists of follicular (FO) and marginal zone (MZ) B cells, which mature from transitional B cells in the spleen and mount T-dependent and T-independent antibody responses, respectively. TACI (Tnfrsf13b) is a member of the TNF-receptor superfamily expressed on mature and transitional B cells, with highest expression on MZ B cells and plasma cells, which is activated by the cytokines BAFF and APRIL. BAFF also stimulates the related receptor BAFFR, which provides signals that are essential for mature B-cell survival. Previous studies of TACI-/- mice have observed that TACI-deficiency leads to an expansion of mature B cells, and therefore it has long been thought that TACI is a negative regulator of mature B-cell survival. However, TACI-/- mice also have elevated levels of BAFF, therefore the B-cell hyperplasia phenotype in TACI-/- mice is most likely a cell-extrinsic effect due to increased BAFF-BAFFR signalling in TACI-/- B cells. To investigate the cell-intrinsic role of TACI, we generated mouse mixed bone marrow chimeras from TACI-/- and WT mice and studied the effect of TACI loss in vivo, without the confounding factor of increased BAFF. Here, we have analysed the transcriptomes of TACI KO and TACI WT marginal zone and follicular B cells by RNAseq.

Project description:Nodal marginal zone lymphoma is a poorly defined entity in the WHO classification, largely based on criteria by exclusion and the diagnosis often remains subjective. Follicular Lymphoma lacking t(14;18), have similar characteristics which results in a major potential diagnostic overlap which this study aims to dissect. Four subgroups of lymphoma samples (n=56) were analyzed with high-resolution arrayCGH; Nodal marginal zone lymphoma, t(14;18)-negative Follicular Lymphoma, localized t(14:18)-positive Follicular Lymphoma and disseminated t(14;18)-positive Follicular Lymphoma. Gains on chromosomes 7, 8 and 12 were observed in all subgroups. The mean number of aberrations was higher in disseminated t(14;18)-positive Follicular Lymphoma compared to localized t(14:18)-positive Follicular Lymphoma (p<0.01) and the majority of alterations in localized t(14:18)-positive Follicular Lymphoma were also found in disseminated t(14;18)-positive Follicular Lymphoma. Nodal marginal zone lymphoma was marked by 3q gains with amplifications of four genes. A different overall pattern of aberrations was seen in t(14;18)-negative Follicular Lymphoma compared to t(14;18)-positive Follicular Lymphoma. t(14;18)-negative Follicular Lymphoma is marked by specific (focal) gains on chromosome 3 as observed in Nodal marginal zone lymphoma. Our results support the notion that localized t(14:18)-positive Follicular Lymphoma represents an early phase of disseminated t(14;18)-positive Follicular Lymphoma. t(14;18)-negative Follicular Lymphoma bears aberrations that are more alike Nodal marginal zone lymphoma, suggesting a relation between these groups. Four subgroups of follicular lymphoma were analyzed: NMZL (n=14), t-FL (n=12), LOC t+FL (n=16), DIS t+FL (n=14).
