Abstract

Fibroblast growth factor 21 (FGF21) is an endocrine hormone produced by the liver that regulates nutrient and metabolic homeostasis. FGF21 production is increased in response to macronutrient imbalance and signals to the brain to suppress sugar intake and sweet-taste preference. However, the central targets mediating these effects have been unclear. Here, we identify FGF21 target cells in the hypothalamus and reveal that FGF21 signaling to glutamatergic neurons is both necessary and sufficient to mediate FGF21-induced sugar suppression and sweet-taste preference. Moreover, we show that FGF21 acts directly in the ventromedial hypothalamus (VMH) to specifically regulate sucrose intake, but not non-nutritive sweet-taste preference, body weight, or energy expenditure. Finally, our data demonstrate that FGF21 affects neuronal activity by increasing activation and excitability of neurons in the VMH. Thus, FGF21 signaling to glutamatergic neurons in the VMH is an important component of the neurocircuitry that functions to regulate sucrose intake.

  • KLB expression is primarily restricted to specific metabolic tissues (liver, pancreas, adipose) and lower in brain; KLB is not expressed in muscle.

    “KLB expression is primarily restricted to specific metabolic tissues (for example, the liver, pancreas and adipose tissue)5, and lower expression is observed in the brain22,48–50. Despite some reports to the contrary51,52, KLB is not expressed in muscle5,41.”

  • KLB is expressed in numerous cell types and regions throughout the hypothalamus and CNS, in contrast to reported restriction to the suprachiasmatic nucleus.

    “In contrast to the reported restriction of KLB expression to the suprachiasmatic nucleus49, KLB is expressed in numerous cell types and regions throughout the hypothalamus48 (and CNS).”

  • FGF21 increases the excitability of KLB+ neurons in the VMH.

    “FGF21 accomplishes this action by increasing the excitability of KLB+ neurons in the VMH48.”

  • Physiological FGF21 signalling to glutamatergic neurons in the paraventricular nucleus regulates basal sucrose intake; FGF21 signalling to glutamatergic neurons in the VMH is required for FGF21-mediated suppression of simple-sugar intake.

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.
