Abstract

Significance: Receptors on the surface of lymphocytes specifically recognize foreign pathogens. The diversity of these receptors sets the range of infections that can be detected and fought off. Recent experiments show that, despite the many differences between these receptors in different cell types and species, their distribution of diversity is a strikingly reproducible power law. By introducing effective models of repertoire dynamics that include environmental and antigenic fluctuations affecting lymphocyte growth or “fitness,” we show that a temporally fluctuating fitness is responsible for the observed heavy tail distribution. These models are general and describe the dynamics of various cell types in different species. They allow for the classification of the functionally relevant repertoire dynamics from the features of the experimental distributions.

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.
