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...

GenomicsPTIP promotes chromatin changes critical for immunoglobulin class switch recombination
Programmed genetic rearrangements in lymphocytes require transcription at antigen receptor genes to promote accessibility for initiating double-strand break (DSB) formation critical for DNA recombination and repair. Here we show that activated B cells deficient in the PTIP component of the MLL3 (mix...

GenomicsFlexible chromatin loops in the VH gene region of the Igh locus facilitate the generation of a diverse antibody repertoire
The immunoglobulin heavy-chain (Igh) locus undergoes large-scale contraction in pro-B cells, which facilitates VH-DJH recombination by juxtaposing distal VH genes next to the DJH- rearranged gene segment in the proximal Igh domain. By high-resolution mapping of long-range interactions, we now demons...

GenomicsRif1 Prevents Resection of DNA Breaks and Promotes Immunoglobulin Class Switching
DNA double-strand breaks (DSBs) represent a threat to the genome because they can lead to loss of genetic information and chromosome rearrangements. The DNA repair protein p53 binding protein 1 (53BP1) protects the genome by limiting nucleolytic processing of DSBs by a mechanism that requires its ph...

TranscriptomicsRelation of Gene Expression Phenotype to Immunoglobulin Mutation Genotype in B Cell Chronic Lymphocytic Leukemia
The most common human leukemia is B cell chronic lymphocytic leukemia (CLL), a malignancy of mature B cells with a characteristic clinical presentation but a variable clinical course. The rearranged immunoglobulin (Ig) genes of CLL cells may be either germ-line in sequence or somatically mutated. La...

TranscriptomicsAllele specific analysis of the immunoglobulin heavy chain locus by simultaneous analysis of the productive and the non-productive allele through paired-end 4C sequencing analysis in mature B cells
In developing B cells the immunoglobulin heavy chain (IgH) locus is thought to move from repressive to permissive chromatin compartments to facilitate its scheduled rearrangement. In mature B cells, maintenance of allelic exclusion has been proposed to involve recruitment of the non-productive IgH a...

ProteomicsIgG M-protein quantification by PRM in blood of multiple myeloma patient
The amino acid sequence of the M-protein for multiple myeloma is unique compared to the polyclonal antibodies in patients’ blood. This uniqueness is exploited to develop an ultra-sensitive M-protein detection method utilizing mass spectrometry (MS). The method involves the de novo amino acid sequenc...
