Abstract

Semaphorins are phylogenetically conserved proteins expressed in most organ systems, including the nervous system. Following their description as axon guidance cues, semaphorins have been implicated in multiple aspects of nervous system development. Semaphorins are key regulators of neural circuit assembly, neuronal morphogenesis, assembly of excitatory and inhibitory synapses, and synaptic refinement. Semaphorins contribute to the balance between excitatory and inhibitory synaptic transmission, and electrical activity can modulate semaphorin signaling in neurons. This interplay between guidance cue signaling and electrical activity has the potential to sculpt the wiring of neural circuits and to modulate their function.

  • Plexins and their cognate semaphorin ligands mediate a variety of cell-cell communications in development, adult physiology, and cancer.

    “In addition to axon pathfinding during neurodevelopment, plexins and their cognate semaphorin ligands also mediate a variety of cell-cell communications in development, adult physiology, and cancer15–18.”

    The Introduction section on pathway-specific connectivity describes Sema3E–PlexinD1 signaling between neurons during CNS circuit development, supporting the developmental cell-communication part of the claim. The passages in our copy do not establish the attributed roles in adult physiology or cancer. (LLM, conf=0.86)

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.
