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...

MetabolomicsGDF15 hijacks B cells to fuel the lifeblood of tumor salvage pyrimidine synthesis
B cell-tumor crosstalk has emerged as a critical determinant of tumor progression; however, its role in metabolic reprogramming and therapeutic resistance remains poorly understood. Here, we uncover a metabolic feedback loop that drives resistance to dihydroorotate dehydrogenase (DHODH) inhibitors. ...

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...

MetabolomicsA metabolic dependency of EBV can be targeted to hinder B cell transformation

Following infection of B cells, Epstein Barr virus (EBV) engages host pathways that mediate cell proliferation and transformation, contributing to the propensity of the virus to drive immune dysregulation and lymphomagenesis. We found that the EBV protein EBNA2 initiates NAD de novo bios...

MetabolomicsSpaceM reveals metabolic states of single cells

A growing appreciation of the importance of cellular metabolism and revelations concerning the extent of cell-cell heterogeneity demand metabolic characterization of individual cells. We present SpaceM, an open-source method for in situ single-cell metabolomics that detects >100 metabolites fr...

MetabolomicsPRDM15 is a master regulator of metabolism essential to sustain B-cell lymphomagenesis
PRDM family members are sequence-specific transcriptional regulators involved in cell identity and fate determination and are often dysregulated in cancer. The PRDM15 gene is of particular interest, given its relatively low expression in adult tissues and its overexpression in follicular lymphomas (...

MetabolomicsMitochondrial respiration in B lymphocytes is essential for humoral immunity by controlling flux of the TCA cycle

To elucidate the function of oxidative phosphorylation (OxPhos) during B-cell differentiation we employ CD23Cre-driven expression of the dominant-negative K320E mutant of the mitochondrial helicase Twinkle (DNT). DNT-expression depletes mitochondrial DNA during B cell maturation, reduces the abun...

MetabolomicsMetabolomic profiling of primary mouse proximal tubule cells (mPTCs) derived from 24-week-old CTR and Atg7 PT-KO kidneys
To explore the role of ATG7 in the kidney PT, we crossed mice homozygous for floxed alleles of Atg7 with Ggt1-Cre mice expressing Cre recombinase under the rat Ggt1 (gamma-glutamyltransferase 1) gene promoter. This generated Atg7fl/fl; γGt1cre/cre mice (hereafter referred to as Atg7 PT-KO), in which...

MetabolomicsHigh-resolution LC-MS/MS lipidomics characterization of wild-type and ATG7-deficient mouse renal proximal tubule cells
This study provides an untargeted lipidomics investigation of ATG7-deficient (cKO) mouse renal proximal tubule cells compared to wild-type (WT) controls to evaluate lipidomic alterations associated with autophagy deficiency. Lipids were extracted from cell culture wells using a single-phase isopropa...
