MetabolomicsB cell expression of the enzyme PexRAP, an intermediary in ether lipid biosynthesis, promotes antibody responses and germinal center size.

The qualities of antibody (Ab) responses provided by B lymphocytes and their plasma cell (PC) descendants are crucial facets of responses to vaccines and microbes. Metabolic processes and products regulate aspects of B cell proliferation and differentiation into germinal center (GC) and PC states...

ProteomicsHSP90 promotes Burkitt lymphoma cell survival by maintaining tonic B cell receptor signaling
Burkitt’s lymphoma (BL) is an aggressive B-cell neoplasm that is currently treated by intensive chemotherapy in combination with anti-CD20 antibodies. Because of their toxicity, current treatment regimens are often not suitable for elderly patients or for patients in developing countries where BL is...

TranscriptomicsGene expression data of BCR-ABL1 transformed B cell precursors from BCL6 wild-type and BCL6 knockout mice
To elucidate the mechanism of BCL6-mediated pre-B cell survival signaling, we investigated the gene expression pattern in BCR-ABL1-transformed BCL6+/+ and BCL6-/- B cell precursors. Pharmacological inhibition of BCR-ABL1 was performed with the BCR-ABL1 kinase inhibitor STI571 (Imatinib). BCR-ABL1 t...

TranscriptomicsNFATc1 controls the survival, function and suppressive capacity of B lymphocytes upon B cell receptor stimulation
Triggering of B cell receptors (BCR) induces a massive synthesis of NFATc1 in splenic B cells. By inactivating the Nfatc1 gene and re-expressing NFATc1 we show that NFATc1 levels are critical for the survival of splenic B cells upon BCR stimulation. NFATc1 ablation led to decreased BCR-induced Ca++ ...

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 ...

TranscriptomicsProstaglandin E2 regulates B cell proliferation through a candidate tumor suppressor, Ptger4
Recognition of foreign antigens by B cell receptor (BCR) on mature B cells leads to their clonal expansion, which is critically important for the effective host defence of the organism. However, excessive antigenic responses or reaction of B cells against body’s own components frequently lead to d...

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...

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...

MetabolomicsImmunoglobulin expression in the endoplasmic reticulum shapes the metabolic fitness of B lymphocytes
The major function of B lymphocytes is to sense antigens and to produce protective antibodies after activation. This function requires the expression of a B-cell antigen receptor (BCR), and evolutionary conserved mechanisms seem to exist that ensure that B cells without a BCR do not develop nor surv...
