Abstract

TNFR2 is predominantly expressed by a subset of human and mouse CD4+CD25+FoxP3+ T regulatory cells (Tregs). In this study, we characterized the phenotype and function of TNFR2+ Tregs in peripheral lymphoid tissues of normal and tumor-bearing C57BL/6 mice. We found that TNFR2 was expressed on 30–40% of the Tregs of the peripheral activated/memory subset that were most highly suppressive. In contrast, TNFR2− Tregs exhibited the phenotype of naive cells and only had minimal suppressive activity. Although not typically considered to be Tregs, CD4+CD25−TNFR2+ cells nevertheless possessed moderate suppressive activity. Strikingly, the suppressive activity of TNFR2+ Tregs was considerably more potent than that of reportedly highly suppressive CD103+ Tregs. In the Lewis lung carcinoma model, more highly suppressive TNFR2+ Tregs accumulated intratumorally than in the periphery. Thus, TNFR2 identifies a unique subset of mouse Tregs with an activated/memory phenotype and maximal suppressive activity that may account for tumor-infiltrating lymphocyte-mediated immune evasion by tumors.

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.
