Abstract

Despite the recognized importance of the dorsal raphe (DR) serotonergic (5‐HT) nuclei in the pathophysiology of depression and anxiety, the molecular components/putative drug targets expressed by these neurons are poorly characterized. Utilizing the promoter of an ETS domain transcription factor that is a stable marker of 5‐HT neurons (Pet‐1) to drive 5‐HT neuronal expression of YFP, we identified 5‐HT neurons in live acute slices. We isolated RNA from single 5‐HT neurons in the ventromedial and lateral wings of the DR and performed single‐cell RNA‐Seq analysis identifying >500 G‐protein coupled receptors (GPCRs) including receptors for classical transmitters, lipid signals, and peptides as well as dozens of orphan‐GPCRs. Using these data to inform our selection of receptors to assess, we found that oxytocin and lysophosphatidic acid 1 receptors are translated and active in costimulating, with the α 1 ‐adrenergic receptor, the firing of DR 5‐HT neurons, while the effects of histamine are inhibitory and exerted at H3 histamine receptors. The inhibitory histamine response provides evidence for tonic in vivo histamine inhibition of 5‐HT neurons. This study illustrates that unbiased single‐cell transcriptomics coupled with functional analyses provides novel insights into how neurons and neuronal systems are regulated.—Spaethling, J.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Systematic analysis and integration of multiple cellular characteristics at single-cell resolution within each raphe nucleus is still lacking.

    “Pioneering work has introduced the molecular diversity of serotonin neurons across the midbrain and hindbrain (Okaty et al., 2015; Spaethling et al., 2014; Wylie et al., 2010), yet systematic analysis and integration of multiple cellular characteristics at single-cell resolution within each raphe nucleus is still lacking.”

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.
