Abstract

We have previously shown that human Th17 lymphocytes are characterized by the selective expression of IL‐23 receptor (IL‐23R), CCR6, CD161, and the transcription factor retinoic acid‐related orphan receptor C (RORC), and originate from a CD161+CD4+ naïve T‐cell precursor in response to the combined activity of IL‐1β and IL‐23. We show here that not only CD4+TCRαβ+, but also CD8+TCRαβ+, CD4−CD8− TCRαβ+, and CD4−CD8− TCRγδ+ circulating lymphocytes that produce IL‐17 express the distinctive marker CD161 on their surface. In addition, we demonstrate that CD161 expression identifies CD8+ and CD4−CD8− umbilical cord blood T cells that already express RORC and IL‐23R mRNA and that can be induced to differentiate into IL‐17‐producing cells in the presence of IL‐1β and IL‐23. Finally, we provide evidence that umbilical cord blood naïve CD4+CD161− T cells, upon lentivirus‐mediated transduction with RORC2 can acquire the ability to express IL‐23R, IL‐1RI, and CD161, as well as to produce IL‐17. Taken together, these data allow to conclude that T‐cell subsets able to produce IL‐17, as well as precursors of IL‐17‐producing T cells, exhibit surface expression of CD161, and that this feature is at least in part RORC2‐dependent.

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.
