Abstract

The discovery of leptin has enhanced understanding of the interrelationship between adipose energy stores and neuronal circuits in the brain involved in energy balance and regulation of the neuroendocrine axis. Leptin levels are dependent on the status of fat stores as well as changes in energy balance as a result of fasting and overfeeding. Although leptin was initially thought to serve mainly as an anti-satiety hormone, recent studies have shown that it mediates the adaptation to fasting. Furthermore, leptin has been implicated in the regulation of the reproductive, thyroid, growth hormone, and adrenal axes, independent of its role in energy balance. Although it is widely known that leptin acts on hypothalamic neuronal targets to regulate energy balance and neuroendocrine function, the specific neuronal populations mediating leptin action on feeding behavior and autonomic and neuroendocrine function are not well understood. In this review, we have discussed how leptin engages arcuate hypothalamic neurons expressing putative orexigenic peptides, e.g., neuropeptide Y and agouti-regulated peptide, and anorexigenic peptides, e.g., pro-opiomelanocortin (precursor of alpha-melanocyte-stimulating hormone) and cocaine- and amphetamine-regulated transcript. We show that leptin's effects on energy balance and the neuroendocrine axis are mediated by projections to other hypothalamic nuclei, e.g., paraventricular, lateral, and perifornical areas, as well as other sites in the brainstem, spinal cord, and cortical and subcortical regions.

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.
