KLF10 Deficiency in CD4+ T Cells Triggers Obesity, Insulin Resistance, and Fatty Liver
Open accessAbstract
CD4 + T cells regulate inflammation and metabolism in obesity. An imbalance of CD4 + T regulatory cells (Tregs) is critical in the development of insulin resistance and diabetes. Although cytokine control of this process is well understood, transcriptional regulation is not. KLF10, a member of the Kruppel-like transcription factor family, is an emerging regulator of immune cell function. We generated CD4 + -T-cell-specific KLF10 knockout (TKO) mice and identified a predisposition to obesity, insulin resistance, and fatty liver due to defects of CD4 + Treg mobilization to liver and adipose tissue depots and decreased transforming growth factor β3 (TGF-β3) release in vitro and in vivo . Adoptive transfer of wild-type CD4 + Tregs fully rescued obesity, insulin resistance, and fatty liver. Mechanistically, TKO Tregs exhibit reduced mitochondrial respiration and glycolysis, phosphatidylinositol 3-kinase (PI3K)-Akt-mTOR signaling, and consequently impaired chemotactic properties. Collectively, our study identifies CD4 + T cell KLF10 as an essential regulator of obesity and insulin resistance by altering Treg metabolism and mobilization.

KLF10 expression is significantly downregulated in Teffs and Tregs isolated from peripheral blood and spleen of high-fat diet-induced obese mice; conditional deletion of KLF10 in CD4+ T cells results in reduced Treg accumulation, leading to adipose tissue inflammation, insulin resistance, obesity, and MASLD; adoptive transfer of Tregs into these mice attenuates these features.
“A recent study reported that KLF10 expression is significantly downregulated in Teffs and Tregs isolated from the peripheral blood and spleen of high-fat diet-induced obese mice (Wara et al. 2020). Moreover, the conditional deletion of KLF10 in CD4+ T cells results in reduced Treg accumulation, leading to adipose tissue inflammation, insulin resistance, obesity, and the development of MASLD (Wara”

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.
