Abstract

The beneficial effects of Neural Precursor Cell (NPC) transplantation in several neurological disorders are well established and they are generally mediated by the secretion of immunomodulatory and neurotrophic molecules. We therefore investigated whether Rett syndrome (RTT), that represents the first cause of severe intellectual disability in girls, might benefit from NPC-based therapy. Using in vitro co-cultures, we demonstrate that, by sensing the pathological context, NPC-secreted factors induce the recovery of morphological and synaptic defects typical of Mecp2 deficient neurons. In vivo, we prove that intracerebral transplantation of NPCs in RTT mice significantly ameliorates neurological functions. To uncover the molecular mechanisms underpinning the mediated benefic effects, we analyzed the transcriptional profile of the cerebellum of transplanted animals, disclosing the possible involvement of the Interferon γ (IFNγ) pathway. Accordingly, we report the capacity of IFNγ to rescue synaptic defects, as well as motor and cognitive alterations in Mecp2 deficient models, thereby suggesting this molecular pathway as a potential therapeutic target for RTT.

  • Cholesterol treatment recovers pre- and post-synaptic defects in Mecp2 HET neurons.

    “By measuring the density of synaptic puncta, we proved that cholesterol treatment recovers pre-and post-synaptic defects, typically shown by HET neurons (Frasca et al., 2024) (Figure 5A-D).”

    From Impaired astrocyte-to-neuron cholesterol trafficking drives synaptic dysfunction in Rett syndrome (2026) · cites this paper as Frasca et al., 2024

    In the Results section on NPC-secreted factors (Fig. 1J–K; page unavailable), Frasca et al. report reduced presynaptic puncta in Mecp2 Het neurons. The cited paper documents postsynaptic puncta defects in Mecp2 KO neurons, but does not establish the corresponding puncta defect in Het neurons. The cholesterol-treatment result is presented as the citing authors’ own finding, not as a finding attributed to Frasca et al. (LLM, conf=0.84)

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.
