Abstract

The lateral hypothalamic area (LHA) acts in concert with the ventral tegmental area (VTA) and other components of the mesolimbic dopamine (DA) system to control motivation, including the incentive to feed. The anorexigenic hormone leptin modulates the mesolimbic DA system, although the mechanisms underlying this control have remained incompletely understood. We show that leptin directly regulates a population of leptin receptor (LepRb)-expressing inhibitory neurons in the LHA and that leptin action via these LHA LepRb neurons decreases feeding and body weight. Furthermore, these LHA LepRb neurons innervate the VTA, and leptin action on these neurons restores VTA expression of the rate-limiting enzyme in DA production along with mesolimbic DA content in leptin-deficient animals. Thus, these findings reveal that LHA LepRb neurons link anorexic leptin action to the mesolimbic DA system.

  • Leptin receptors are located in hypothalamic areas beyond the arcuate nucleus, including the ventromedial, dorsomedial, premammillary, lateral, and perifornical areas, where they likely contribute to leptin's effects on food intake and energy expenditure.

    “But clearly, leptin receptors are located in other hypothalamic areas such as the ventromedial, dorsomedial, and premammillary nuclei, as well as the lateral and perifornical areas where they likely contribute to leptin's effects on food intake and energy expenditure”

  • Lateral hypothalamic neurons expressing orexin and other transmitters such as neurotensin provide modulatory input to midbrain dopamine neurons.

    “Recent investigations show that lateral hypothalamic neurons expressing orexin ([77](#B77), [199](#B199)) and other transmitters such as neurotensin ([101](#B101), [107](#B107)) provide modulatory input to midbrain dopamine neurons”

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.
