Orexigen-sensitive NPY/AgRP pacemaker neurons in the hypothalamic arcuate nucleus

Abstract

The hypothalamic arcuate nucleus (ARC) integrates and responds to satiety and hunger signals and forms the origins of the central neural response to perturbations in energy balance. Here we show that rat ARC neurons containing neuropeptide Y (NPY) and agouti-related protein (AgRP), which are conditional pacemakers, are activated by orexigens and inhibited by the anorexigen leptin. We propose a neuron-specific signaling mechanism through which central and peripheral signals engage the central neural anabolic drive.

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.
