Abstract

Helping T Helper Transcription: Members of the interferon response family of transcription factors (IRFs) are specifically expressed in immune cells and are known to regulate their differentiation. IRF4 and IRF8 regulate gene expression by binding to other transcription factors, which results in their recruitment to composite motifs in the genome. Although the specific mechanism of how this regulation works in some immune cells is understood, how it occurs in T cells is not clear because the transcription factors that normally partner with IRFs are absent. Using genomic analysis, Glasmacher et al. (p. 975 , published online 13 September; see the Perspective by Martinez and Rao ) now identify IRF4–AP-1 composite elements in T helper 17 (T H 17) cells and show that IRF4 and the AP-1 factor Batf cooperatively assemble on a large array of genes required for T H 17 cell differentiation and function. Assembly of such heterodimers was also observed in T H 2 cells, B cells, and dendritic cells, which suggests the general importance of this motif in immune cell differentiation.

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

  • Genes affected by positive or negative regulators significantly overlap with genes bound by key CD4+ transcription factors Foxp3, Batf, Irf4, and ROR-γt.

    “The genes affected by either positive or negative regulators also significantly overlap with those bound by key CD4+ transcription factors (e.g., Foxp326,27, Batf, Irf4, and ROR-γt28,29, Xiao et al., unpublished data).”

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.
