Abstract

In principle, humans can produce an antibody response to any non-self-antigen molecule in the appropriate context. This flexibility is achieved by the presence of a large repertoire of naive antibodies, the diversity of which is expanded by somatic hypermutation following antigen exposure 1. The diversity of the naive antibody repertoire in humans is estimated to be at least 10 12 unique antibodies 2. Because the number of peripheral blood B cells in a healthy adult human is on the order of 5 × 10 9, the circulating B cell population samples only a small fraction of this diversity. Full-scale analyses of human antibody repertoires have been prohibitively difficult, primarily owing to their massive size. The amount of information encoded by all of the rearranged antibody and T cell receptor genes in one person-the 'genome' of the adaptive immune system-exceeds the size of the human genome by more than four orders of magnitude. Furthermore, because much of the B lymphocyte population is localized in organs or tissues that cannot be comprehensively sampled from living subjects, human repertoire studies have focused on circulating B cells 3. Here we examine the circulating B cell populations of ten human subjects and present what is, to our knowledge, the largest single collection of adaptive immune receptor sequences described to date, comprising almost 3 billion antibody heavy-chain sequences. This dataset enables genetic study of the baseline human antibody repertoire at an unprecedented depth and granularity, which reveals largely unique repertoires for each individual studied, a subpopulation of universally shared antibody clonotypes, and an exceptional overall diversity of the antibody repertoire.

  • NGS provides a snapshot of millions of antibody sequences sampled from the theoretically possible 1012-1015 antibody sequences in a human repertoire.

    “NGS provides a snapshot of millions of antibody sequences sampled from the theoretically possible 1012–1015 antibody sequences in a human repertoire [23, 24].”
  • Together with the diversity introduced by V(D)J recombination, somatic hypermutation can produce an estimated 1012-1015 possible antibody sequences.

    “Together with the diversity introduced by V(D) J recombination, somatic hypermutation can produce an estimated 1012–1015 possible antibody sequences [23, 24].”
  • Each of the estimated 5 × 109 B-cells in an organism produces a distinct B-cell receptor or antibody through somatic recombination of variable, diversity, joining and constant gene segments.

    “Each of the estimated 5 × 109 B-cells in an organism [23] produces a distinct B-cell receptor (membrane-bound) or antibody (in soluble form) through somatic recombination of variable (V), diversity (D), joining (J) and constant (C) gene segments [28, 29].”
  • Despite vast numbers of diverse sequences in a typical human antibody repertoire, a non-trivial amount of these is shared between individuals.

    “From a sequence perspective, it was demonstrated recently that despite the vast numbers of diverse sequences in a typical human antibody repertoire, a non-trivial amount of these is shared between individuals [23, 223].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
