TranscriptomicsGene expression of murine B cells activated via TLR4 or TLR4 + CD40: Group1 naM-CM-/ve B cells, Group2 LPS activated B cells 24h, Group3 LPS + anti-CD40 activated B cells 24h, Group4 LPS activated B cells 72h, and Group5 LPS + anti-CD40 activated B cells 72h.
Murine B cells can be activated via the surface receptors TLR4 and CD40. For a global assessment of differences in gene expression between these two different modes of B cell activation a genome wide transcriptome analysis was performed. In order to dissect different gene expression profiles of B ce...

TranscriptomicsATM-deficient B cell lymphomas
Ataxia-telangiectasia mutated (ATM) kinase plays a central role in maintaining genomic integrity. In both humans and mice, ATM deficiency is associated with an increased incidence of lymphoid cancers that are primarily T cell in origin. We demonstrate here that when T cells are removed as targets fo...

TranscriptomicsRole of miR-125b in B-cell acute lymphoblastic leukemia (B-ALL)
B-cell acute lymphoblastic leukemia (B-ALL) is often associated with chromosomal translocations leading to the deregulation of proto-oncogenes. MicroRNAs can also be affected by chromosomal alterations and thus contribute to carcinogenesis. The microRNA miR-125b-1 is over-expressed in B-ALL cases wi...

TranscriptomicsTranscription profiling of mouse follicular and marginal zone B-cells
Immature B cells in spleens of mouse and human differentiate into at least two subsets of mature B cells, the follicular (FO) B cells and the marginal zone (MZ) B cells, but functions, maturation and other properties of these cells are largely unknown. To solve these questions, in this study, we per...

MetabolomicsMetabolomics profiling (GC-MS and LC-MS) for time-course differentiation of pre-B cells-like (B3 cell line) under the controlled induction of the transcription factor Ikaros (STATegra Project)
The main goal of the project is to develop a new generation of bioinformatics resources for the integrative analysis of multiple types of 'omics data. These resources include both novel statistical methodologies as well as user-friendly software implementations. STATegra methods address many aspects...

TranscriptomicsSingle-cell RNA and B cell receptor profiling of B cell response to SARS-CoV-2 vaccination
We generated single-cell transcriptomic and BCR sequencing data of B cells from peripheral blood samples taken from a SARS-CoV-2-antigen-naive cohort being vaccinated with the SARS-CoV-2 mRNA-1273 vaccine. Blood samples were collected at the baseline timepoint D-1 (i.e. one day prior to the initial ...

TranscriptomicsTranscription profiling of mouse AM-14 B cells stimulated through the B cell receptor (BCR) and/or Toll-like receptors (TLR)
We have previously shown that rheumatoid factors (RF) produced by Fas-deficient autoimmune-prone mice typically bind autologous IgG2a with remarkably low affinity. Nevertheless, B cells representative of this RF population proliferate vigorously in response IgG2a/chromatin immune complexes through a...

TranscriptomicsRecurrent 11q aberrations in MYC-neg mature aggressive B-cell lymphomas resembling BL
Copy number analysis using Agilent 244k or 180k (Case9) arrays was performed for 8 MYC-negative B-cell lymphomas, with sex-matched control DNAs Agilent 244k (cases 4-7 and 10-12) and 180k (Case9) arrays

TranscriptomicsA distinct effector B cell population drives autoantibody production in SARS-CoV-2 infection
This study included single-cell RNA-seq and scATAC-seq data from PBMCs from 12 COVID-19 individuals at acute infection.

TranscriptomicsSingle-cell RNA and BCR sequencing of naive B cells cultured in IgG class-switching polarising conditions
Naive B cells (CD27-IgD+) were obtained from 3 healthy controls and cultured in vitro under anti-IgM, CD40L and IFN-gamma to polarise class-switching towards IgG isotypes. Single-cell RNA and BCR sequencing libraries were prepared at Day 0 (before addition of stimuli), Day 3 and Day 6 of the cell cu...
