Abstract

Mucosal-associated invariant T cells (MAIT cells) detect microbial vitamin B2 derivatives presented by the antigen-presenting molecule MR1. Here we defined three developmental stages and checkpoints for the MAIT cell lineage in humans and mice. Stage 1 and stage 2 MAIT cells predominated in thymus, while stage 3 cells progressively increased in abundance extrathymically. Transition through each checkpoint was regulated by MR1, whereas the final checkpoint that generated mature functional MAIT cells was controlled by multiple factors, including the transcription factor PLZF and microbial colonization. Furthermore, stage 3 MAIT cell populations were expanded in mice deficient in the antigen-presenting molecule CD1d, suggestive of a niche shared by MAIT cells and natural killer T cells (NKT cells). Accordingly, this study maps the developmental pathway and checkpoints that control the generation of functional MAIT cells.

  • The development and maturation of MAIT cells are dependent on microbiota, as demonstrated by reduced numbers of MAIT cells in GF mice, which can be restored through microbial colonization.

    “The development and maturation of MAIT cells are dependent on microbiota, as demonstrated by reduced numbers of MAIT cells in GF mice, which can be restored through microbial colonization.”
  • The microbiota is necessary for MAIT cells in the thymus, spleen, gut, skin, lungs, and liver.

    “A comparison of mice housed in conventional specific-pathogen-free (SPF) conditions to germ-free (GF) animals confirmed previous observations that the microbiota is necessary for the presence of MAIT cells in the thymus, spleen, and gut (17, 18), and extended this requirement for MAIT cells in the skin, lungs, and liver (Fig. 1B).”

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.
