A Unifying Model for Molecular Determinants of the Pre-selection V Repertoire


ABSTRACT: Analysis of histone modifications in double negative thymocytes from RAG-/- mice For the ChIP-seq, input and immunoprecipitated DNA was given to The Scripps DNA Array Facility, where it was prepared for massively parallel sequencing on Illumina HiSeq 2000.

The primary antigen receptor repertoire is sculpted by the process of V(D)J recombination, which must strike a balance between diversification and favoring gene segments with specialized functions. The precise determinants of how often gene segments are chosen to complete variable region coding exons remain elusive. We quantified Vβ use in the preselection Tcrb repertoire and report relative contributions of 13 distinct features that may shape their recombination efficiencies, including transcri  ...[more]
