Abstract

The specification of spinal interneuron and motor neuron identities initiates within progenitor cells, while motor neuron subtype diversification is regulated by hierarchical transcriptional programs implemented postmitotically. Here we find that mice lacking GDE2, a six-transmembrane protein that triggers motor neuron generation, exhibit selective losses of distinct motor neuron subtypes, specifically in defined subsets of limb-innervating motor pools that correlate with the loss of force-generating alpha motor neurons. Mechanistically, GDE2 is expressed by postmitotic motor neurons but utilizes extracellular glycerophosphodiester phosphodiesterase activity to induce motor neuron generation by inhibiting Notch signaling in neighboring motor neuron progenitors. Thus, neuronal GDE2 controls motor neuron subtype diversity through a non-cell-autonomous feedback mechanism that directly regulates progenitor cell differentiation, implying that subtype specification initiates within motor neuron progenitor populations prior to their differentiation into postmitotic motor neurons.

  • GDE2 is one of three known GPI-anchor cleaving enzymes in vertebrates and the only one expressed in neurons.

    “GDE2 is one of three known GPI-anchor cleaving enzymes in vertebrates that function at the cell surface, and the only one expressed in neurons (22–26).”

    From GDE2-RECK controls ADAM10 α-secretase–mediated cleavage of amyloid precursor protein (2021) · cites this paper as [24]

    The Results section (“GDE2 expression in spinal motor neurons”; page unavailable) documents GDE2 expression in motor neurons. The Discussion says GDE2’s direct substrates had not been definitively identified; our copy does not establish that it cleaves GPI anchors, that there are three such vertebrate enzymes, or that GDE2 alone is expressed in neurons.

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.
