Abstract

The brainstem dorsal vagal complex (DVC) is known to regulate energy balance and is the target of appetite-suppressing hormones, such as glucagon-like peptide 1 (GLP-1). Here we provide a comprehensive genetic map of the DVC and identify neuronal populations that control feeding. Combining bulk and single-nucleus gene expression and chromatin profiling of DVC cells, we reveal 25 neuronal populations with unique transcriptional and chromatin accessibility landscapes and peptide receptor expression profiles. GLP-1 receptor (GLP-1R) agonist administration induces gene expression alterations specific to two distinct sets of Glp1r neurons-one population in the area postrema and one in the nucleus of the solitary tract that also expresses calcitonin receptor (Calcr). Transcripts and regions of accessible chromatin near obesity-associated genetic variants are enriched in the area postrema and the nucleus of the solitary tract neurons that express Glp1r and/or Calcr, and activating several of these neuronal populations decreases feeding in rodents. Thus, DVC neuronal populations associated with obesity predisposition suppress feeding and may represent therapeutic targets for obesity.

  • It is well-established that GLP-1RAs activate neurons in the area postrema and nucleus tractus solitarius and induce differential gene expression in the area postrema.

    “It is well-established, however, that GLP-1RAs activate neurons in the AP and the NTS (22, 63) and induce differential gene expression in the AP (63, 107), findings relevant because of the well-established role of the AP in sensing nausea-inducing stimuli (48, 108).”

  • GLP-1R neurons in the area postrema are a heterogeneous population, with subsets co-expressing Gfral, encoding the GDF15 receptor known to be involved in the neural circuitry for nausea, or Prlhr, encoding the receptor for prolactin-releasing peptide hormone shown to mediate satiety without aversion.

    “Several sequencing studies have shown that GLP-1R neurons in the AP are a heterogeneous population, with subsets co-expressing Gfral (48, 107), encoding the GDF15 receptor known to be involved in the neural circuitry for nausea (114), or Prlhr, encoding the receptor for prolactin-releasing peptide hormone shown to mediate satiety without aversion (115).”

    From GLP-1 and the Neurobiology of Eating Control: Recent Advances (2025) · cites this paper as [107]

  • GLP-1R neurons in both the NTS and AP exhibit substantial molecular heterogeneity, including in cell surface receptor expression.

    “GLP-1R neurons in both the NTS and AP exhibit substantial molecular heterogeneity, including in cell surface receptor expression (48, 107, 118, 119).”

    From GLP-1 and the Neurobiology of Eating Control: Recent Advances (2025) · cites this paper as [107]

  • AP and NTS GLP1R neurons are largely distinct from other DVC cell types.

    “This analysis also suggests that APGLP1R and NTSGLP1R neurons are largely distinct from other DVC cell types”
  • Reanalysis of three single-cell/nucleus RNA sequencing datasets showed that AP and NTS GLP1R neurons are mixed excitatory and inhibitory populations, with a greater proportion of NTS GLP1R neurons being excitatory.

    “we combined and re-analyzed three existing single cell/nucleus RNA sequencing datasets13,16,17 to determine that APGLP1R and NTSGLP1R neurons are mixed excitatory and inhibitory populations, with a greater proportion of NTSGLP1R neurons being excitatory”

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.
