Human genetic variation shapes the antibody repertoire across B cell development The peripheral antibody repertoire is shaped by inherited genetic variation and selection during B cell development. However, how the repertoire changes across developmental stages—and the relative im...

New preprint from our group in collaboration with the awesome Prof. Ranjan Sen (NIH). We show that IGH polymorphisms establish inter-individual differences in the pro-B antibody repertoire that persist into the naive B cell pool. Oscar L. Rodriguez is killing it! www.biorxiv.org/content/10.1...

Germline polymorphism in the immunoglobulin kappa and lambda loci explain variation in the expressed light chain antibody repertoire Variation in antibody (Ab) responses contributes to disease outcomes and therapeutic responsiveness, the determinants of which remain incompletely understood. This study demonstrates that polymorphism...

Turns out...just like in the antibody heavy chain repertoire, germline variants in the immunoglobulin lambda and kappa loci influence the composition of light chain B cell receptors!

Our collaborative paper on #Nanopore sequencing is now available on #BioRxiv. Among several new variants, we characterize a large duplication in the IGHC region, suggesting non-canonical class switching between the duplicated isotypes in #Bcells.
