Abstract

Delineating the basic cellular components of cortical inhibitory circuits remains a fundamental issue in order to understand their specific contributions to microcircuit function. It is still unclear how current classifications of cortical interneuron subtypes relate to biological processes such as their developmental specification. Here we identified the developmental trajectory of neurogliaform cells (NGCs), the main effectors of a powerful inhibitory motif recruited by long-range connections. Using in vivo genetic lineage-tracing in mice, we report that NGCs originate from a specific pool of 5-HT3AR-expressing Hmx3+ cells located in the preoptic area (POA). Hmx3-derived 5-HT3AR+ cortical interneurons (INs) expressed the transcription factors PROX1, NR2F2, the marker reelin but not VIP and exhibited the molecular, morphological and electrophysiological profile of NGCs. Overall, these results indicate that NGCs are a distinct class of INs with a unique developmental trajectory and open the possibility to study their specific functional contribution to cortical inhibitory microcircuit motifs.

  • Most neurogliaform cells and multipolar NPY+ interneurons do not derive from Nkx2-1-expressing progenitors and most likely originate from the POH domain.

    “Most of these cells do not derive from Nkx2-1-expressing progenitor cells”

    From Development and Functional Diversification of Cortical Interneurons (2018) · cites this paper as Niquille et al., 2018

  • The CGE produces all VIP+ and CCK+ cortical interneurons along with several less abundant types such as single bouquet cells.

  • Neurogliaform cells and multipolar NPY+ interneurons are born in the preoptic region.

    From Development and Functional Diversification of Cortical Interneurons (2018) · cites this paper as Niquille et al., 2018

  • Interneurons generated in the preoptic region, especially neurogliaform cells, preferentially reach the cortex through the marginal zone.

    “In addition, it has been suggested that interneurons generated in the preoptic region – most notably neurogliaform cells (Niquille et al., 2018) – preferentially reach the cortex through the MZ (Zimmer et al., 2011).”

    From Development and Functional Diversification of Cortical Interneurons (2018) · cites this paper as Niquille et al., 2018

  • Some CGE cell types (e.g., some neurogliaform cells) may be developmentally derived from the nearby preoptic region (PO).

    “Note that some of the CGE cell types (e.g., some neurogliaform cells) may, in fact, be developmentally derived from the nearby preoptic region (PO) (Niquille et al., 2018).”

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.
