Abstract

Visceral adipose tissue (VAT) hosts a population of regulatory T (Treg) cells, with a unique phenotype, that controls local and systemic inflammation and metabolism. Generation of a T cell receptor transgenic mouse line, wherein VAT Tregs are highly enriched, facilitated study of their provenance, dependencies, and activities. We definitively established a role for T cell receptor specificity, uncovered an unexpected function for the primordial Treg transcription-factor, Foxp3, evidenced a cell-intrinsic role for interleukin-33 receptor, and ordered these dependencies within a coherent scenario. Genesis of the VAT-Treg phenotype entailed a priming step in the spleen, permitting them to exit the lymphoid organs and surveil nonlymphoid tissues, and a final diversification process within VAT, in response to microenvironmental cues. Understanding the principles of tissue-Treg biology is a prerequisite for precision-targeting strategies.

  • Tissue Treg cell precursor development is initiated in lymphatic organs and follows a multistep model.

    “Tissue Treg cell precursor development is initiated in lymphatic organs and, thereby, follows a multistep model [375, 377, 452, 453].”

    From Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition) (2021) · cites this paper as [452]

    The Abstract and Discussion (pages not provided) describe a two-stage process for visceral adipose tissue (VAT) Treg cells: priming in the spleen, followed by diversification in VAT. This supports the lymphoid-organ and multistep elements, but the paper establishes the model for VAT Tregs, not tissue Tregs generally. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • TCR signaling is thought to contribute to Treg cell accumulation in the brain and VAT.

    “As TCR signaling is thought to contribute to Treg cell accumulation in the brain and VAT 27,35”

    From Amphiregulin from regulatory T cells promotes liver fibrosis and insulin resistance in non-alcoholic steatohepatitis (2024) · cites this paper as [35]

    The Discussion section, “The TCR, Foxp3 and IL-33 control VAT-Treg cell accumulation” (page unavailable), says a particular TCR could drive Treg expansion or retention in VAT. The cited paper does not establish the corresponding point for the brain, so it supports only the VAT portion of the claim. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • VAT Treg cells have a role in protecting from metabolic disease.

    “VAT Treg cells were analyzed due to their documented unique transcriptome and T cell receptor (TCR) repertoire, as well as their role in protecting from metabolic disease 22,33-36 .”

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.
