Abstract

Type 2 cytokines are important signals triggering biogenesis of thermogenic beige adipocytes in white adipose tissue (WAT) during cold acclimation. However, how cold activates type 2 immunity in WAT remains obscure. Here we show that cold-induced type 2 immune responses and beiging in subcutaneous WAT (scWAT) are abrogated in mice with adipose-selective ablation of FGF21 or its co-receptor β-Klotho, whereas such impairments are reversed by replenishment with chemokine CCL11. Mechanistically, FGF21 acts on adipocytes in an autocrine manner to promote the expression and secretion of CCL11 via activation of ERK1/2, which drives recruitment of eosinophils into scWAT, leading to increases in accumulation of M2 macrophages, and proliferation and commitment of adipocyte precursors into beige adipocytes. These FGF21-elicited type 2 immune responses and beiging are blocked by CCL11 neutralization. Thus, the adipose-derived FGF21-CCL11 axis triggers cold-induced beiging and thermogenesis by coupling sympathetic nervous system to activation of type 2 immunity in scWAT.

Claims other papers make about this one

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

  • During acute cold, FGF21 signals directly to adipose tissue to regulate adipose thermogenesis by inducing the expression and secretion of CCL11.

    “During acute cold, FGF21 signals directly to adipose tissue to regulate adipose thermogenesis by inducing the expression and secretion of the chemokine CCL11 (52).”
  • In mice, circulating FGF21 levels increase in response to cold in some studies but not in others.

    “However, while an increase in circulating levels of FGF21 has been reported in response to cold in mice (49), this has not been observed in other studies (36, 52).”
  • Both Fgf21 total knockout mice and adipose-specific Fgf21 knockout mice exhibit reduced body temperature in response to acute cold exposure.

    “Consistent with a functional role for FGF21 during cold, both Fgf21 total knockout mice (36) and adipose-specific Fgf21 knockout mice (52) exhibit reduced body temperature in response to acute cold exposure.”
  • CCL11 recruits eosinophils to subcutaneous adipose tissues, which promotes the beiging of WAT depots.

    “CCL11 then functions to recruit eosinophils to subcutaneous adipose tissues, which promotes the beiging of WAT depots (52).”
  • In response to cold, Fgf21 mRNA expression is upregulated in both WAT and BAT.

    “Fgf21 mRNA expression is upregulated in both WAT (36, 52) and BAT (15, 36, 49, 52) in response to cold.”

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.
