Hypothalamic sensing of fatty acids

Lam, Tony K T, Schwartz, Gary J, Rossetti, Luciano·2005·Nature Neuroscience

Abstract

Selective regions of the brain, including the hypothalamus, are capable of gathering information on the body's nutritional status in order to implement appropriate behavioral and metabolic responses to changes in fuel availability. This review focuses on direct metabolic signaling within the hypothalamus. There is growing evidence supporting the idea that fatty acid metabolism within discrete hypothalamic regions can function as a sensor for nutrient availability that can integrate multiple nutritional and hormonal signals.

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?

  • Free fatty acid sensing by the hypothalamus is a well-established modulator of neuronal activity, affecting peripheral metabolism.

    “Free fatty acid sensing by the hypothalamus is a well-established modulator of neuronal activity57, affecting peripheral metabolism58–60”
  • Basal levels of fatty acid oxidation enzymes and fatty acid transport proteins (such as FATP-1, FATP-4, and FAT/CD36) are expressed in hypothalamic neurons.

    “However, basal levels of FAO enzymes and FA transport proteins (such as FATP-1, FATP-4, and FAT/CD36) are expressed in hypothalamic neurons ([93](#B93), [95](#B95)).”

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.
