Minireview: Leptin and Development of Hypothalamic Feeding Circuits

Bouret, Sebastien G., Simerly, Richard B.·2004·Endocrinology

Abstract

The arcuate nucleus of the hypothalamus (ARH) is a critical component of the forebrain pathways that regulate energy homeostasis, and it plays a particularly important role in relaying leptin signal to other part of the hypothalamus. However, until recently, little was known about the development of these critical pathways. Recent work investigating the development of leptin-sensitive hypothalamic pathways suggests possible developmental mechanisms that may contribute to obesity later in life. Anatomic findings indicate that ARH circuits are structurally and functionally immature until the third week of postnatal life in mice. Recent data also suggest that leptin is required for normal development of ARH pathways and that this developmental activity of leptin is restricted to a neonatal window of maximum sensitivity that corresponds to a period of elevated leptin secretion. Thus, leptin may function to organize formation of hypothalamic circuitry in much the same way that sex steroids act on sexually dimorphic circuits. Perturbations in perinatal nutrition that alter leptin levels may, therefore, have enduring consequences for the formation and function of circuits regulating food intake and body weight.

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.
