Abstract

Lymphocytes Layer It On: Cells of the immune system begin to develop from hematopoietic stem cells (HSCs) during fetal life. In the adult, HSCs continue to produce immune cells to replenish dying cells or in response to an infection. In mice and birds, immune cell development occurs in a “layered” manner, whereby distinct populations of HSCs that arise at different times during development generate distinct immune cell lineages. In contrast, development of human immune cells, and T lymphocytes in particular, is thought to be linear. Mold et al. (p. 1695 ; see the Perspective by Betz ) now show that T lymphocyte development in humans is also “layered,” and strategically so. T cells that arise from fetal HSCs are enriched in regulatory T cells, which promote immune tolerance, rather than classical T cells, which readily respond to foreign antigen. By favoring the development of regulatory T cell populations during fetal life, the immune system is perhaps better able to keep responses to maternal antigens in check. The development of large numbers of classical T cells is delayed until after birth when infectious agents represent a more imminent threat.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Fetal naive CD4+ T cells tend to develop towards Foxp3+ CD25+ regulatory T cells through TGF-β, promoting self-tolerance.

    “For example, though fetal naive CD4+ T cells respond strongly to alloantigens, they tend to develop towards Foxp3+ CD25+ regulatory T cells (Treg) through the influence of TGF-β [19], and thus actively promote self-tolerance.”

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.
