Abstract

Significance: Liver-derived metabolic hormone fibroblast growth factor 21 (FGF21) improves insulin sensitivity and extends lifespan in mice. Aging also compromises the adaptive immune system by reducing T-cell production from the thymus. In this paper, we describe a new immunological function of FGF21 as a regulator of T-cell production from thymus in aging. The overexpression of FGF21 prevents thymic lipoatrophy, which protects the mice from age-induced loss of naïve T cells. FGF21 expression in thymic epithelial cells and signaling in thymic stromal cells support thymic function in aging. Loss of FGF21 in mice increases lethality postirradiation and delays the reconstitution of thymus. Hence, we highlight FGF21 as an immunometabolic regulator that can be harnessed to delay immune senescence.

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.
