BCR repertoire sequencing: different patterns of B cell activation after two Meningococcal vaccines.
Next-generation sequencing was used to investigate the B cell receptor heavy chain transcript repertoire of different B cell subsets (naïve, marginal zone, IgM memory and IgG memory) at baseline, and of plasma cells 7 days following administration of serogroup ACWY meningococcal polysaccharide and p...

| description | Next-generation sequencing was used to investigate the B cell receptor heavy chain transcript repertoire of different B cell subsets (naïve, marginal zone, IgM memory and IgG memory) at baseline, and of plasma cells 7 days following administration of serogroup ACWY meningococcal polysaccharide and protein-polysaccharide conjugate vaccines. Baseline B cell subsets could be distinguished from each other using a small number of repertoire properties (clonality, mutation from germ-line and complementarity-determining region 3 length) that were conserved between individuals. However, analyzing the complementarity-determining region 3 amino acid sequence (which is particularly important for antigen binding) of the baseline subsets showed few sequences shared between individuals. In contrast, day 7 plasma cells demonstrated nearly tenfold greater sequence sharing between individuals than the baseline subsets, consistent with the plasma cells being induced by the vaccine antigen, and sharing specificity for a more limited range of epitopes. By annotating plasma cell sequences based on IgG subclass usage and mutation, and also comparing them to the sequences of the baseline cell subsets, we were able to identify different signatures after the polysaccharide and conjugate vaccines. Plasma cells produced after conjugate vaccination were predominantly IgG1, and most related to IgG memory cells. In contrast, after polysaccharide vaccination, the plasma cells were predominantly IgG2, less mutated, and were equally likely to be related to marginal zone, IgM memory or IgG memory cells. High-throughput B cell repertoire sequencing thus provides a unique insight into patterns of B cell activation not possible from more conventional measures of immunogenicity.Immunology and Cell Biology accepted article preview online, 15 May 2015. doi:10.1038/icb.2015.57. |
