Mechanisms of leptin action and leptin resistance.

Myers, Martin G., Cowley, Michael A., Münzberg, Heike·2008·Annual Review of Physiology

Abstract

The adipose tissue-derived hormone leptin acts via its receptor (LRb) in the brain to regulate energy balance and neuroendocrine function. LRb signaling via STAT3 and a number of other pathways is required for the totality of leptin action. The failure of elevated leptin levels to suppress feeding and mediate weight loss in common forms of obesity defines a state of so-called leptin resistance. A number of mechanisms, including the leptin-stimulated phosphorylation of Tyr(985) on LRb and the suppressor of cytokine signaling 3, attenuate leptin signaling and promote a cellular leptin resistance in obesity. Several unique features of the arcuate nucleus of the hypothalamus may contribute to the severity of cellular leptin resistance in this region. Other mechanisms that govern feeding behavior and food reward may also underlie the inception of obesity.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Deficient leptin signaling because of hyperleptinemia or because of hypo- or aleptinemia caused by mutations of either leptin or the leptin receptor genes results in hyperphagia and decreased energy expenditure in rodents and humans.

    “Deficient leptin signaling because of hyperleptinemia (as described above) or because of hypo-or aleptinemia caused by mutations of either leptin or the leptin receptor genes results in hyperphagia and decreased energy expenditure in rodents and humans (13).”

  • Deficient leptin signaling results in obesity with increased lipid storage and dysfunction of several neuroendocrine axes, immune and autonomic systems.

    “The result is not only an increasing degree of obesity associated with increased lipid storage in muscle, liver, and other tissues but also dysfunction of several neuroendocrine axes, including the reproductive, thyroid, and adrenal axes, as well as abnormal function of the immune and autonomic system (ie, thermoregulation, energy expenditure, and others) (5, 13, 14).”

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.
