Abstract

Lhx6 and Lhx8 transcription factor coexpression in early-born MGE neurons is required to induce neuronal Shh expression. We provide evidence that these transcription factors regulate expression of a Shh enhancer in MGE neurons. Lhx6 and Lhx8 are also required to prevent Nkx2-1 expression in a subset of pallial interneurons. Shh function in early-born MGE neurons was determined by genetically eliminating Shh expression in the MGE mantle zone (MZ). This mutant had reduced SHH signaling in the overlying progenitor zone, which led to reduced Lhx6, Lhx8, and Nkx2-1 expression in the rostrodorsal MGE and a preferential reduction of late-born somatostatin(+) and parvalbumin(+) cortical interneurons. Thus, Lhx6 and Lhx8 regulate MGE development through autonomous and nonautonomous mechanisms, the latter by promoting Shh expression in MGE neurons, which in turn feeds forward to promote the developmental program of the rostrodorsal MGE.

  • Lhx6 and Lhx8 are co-expressed in some CNU and hypothalamus GABAergic types, but Lhx6 is also specifically expressed in MGE types.

    “Lhx6 and Lhx8 are co-expressed in some CNU and hypothalamus GABAergic types110,111, but Lhx6 is also specifically expressed in MGE types.”

    From A high-resolution transcriptomic and spatial atlas of cell types in the whole mouse brain (2023) · cites this paper as [110]

    The Results section reports Lhx6 and Lhx8 coexpression in more than 90% of cells in the embryonic MGE subventricular zone (page unavailable). The Discussion links both genes to striatal interneuron development, but our copy does not establish their coexpression in the cited CNU GABAergic types or address hypothalamic GABAergic types.

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.
