Abstract

We found that leptin receptors were expressed in hypothalamic astrocytes and that their conditional deletion led to altered glial morphology and synaptic inputs onto hypothalamic neurons involved in feeding control. Leptin-regulated feeding was diminished, whereas feeding after fasting or ghrelin administration was elevated in mice with astrocyte-specific leptin receptor deficiency. These data reveal an active role of glial cells in hypothalamic synaptic remodeling and control of feeding by leptin.

  • Unc13a expression in mushroom bodies plays a fundamental role in olfactory memory encoding in Drosophila, and hippocampal expression of Lpl is necessary for synaptic vesicle recycling and acquisition of memories in mice.

    “Unc13a expression in mushroom bodies plays a fundamental role in olfactory memory encoding in Drosophila [86], and hippocampal expression of lipoprotein lipase (Lpl) is necessary for synaptic vesicle recycling and acquisition of memories in mice [87].”

    From Rapid changes in plasma corticosterone and medial amygdala transcriptome profiles during social status change reveal molecular pathways associated with a major life history transition in mouse dominance hierarchies (2025) · cites this paper as [87]

    Citation [87] is attached to the claim about hippocampal Lpl in mice, not the preceding Drosophila claim. The Online Methods (RT-PCR and Ribosome profiling; page unavailable) mention hippocampal samples, but neither that passage nor searches for Lpl, lipoprotein lipase, synaptic vesicle recycling, and memory acquisition address the attributed role of Lpl. (LLM, conf=0.76)

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.
