Redox dysregulation, neurodevelopment, and schizophrenia

Abstract

In schizophrenia, a developmental redox dysregulation constitutes one 'hub' on which converge genetic impairments of glutathione synthesis and environmental vulnerability factors generating oxidative stress. Their timing at critical periods of neurodevelopment could play a decisive role in inducing impairment of neural connectivity and synchronization as observed in schizophrenia. In experimental models, such redox dysregulation induces anomalies strikingly similar to those observed in patients. This is mediated by hypoactive NMDA receptors, impairment of fast-spiking parvalbumin GABA interneurons and deficit in myelination. A treatment restoring the redox balance without side effects yields improvements of negative symptoms in chronic patients. Novel interventions based on these mechanisms if applied in early phases of the disease hold great therapeutic promise.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Redox dysregulation contributes to aberrant developmental trajectories in schizophrenia and early correction of this imbalance may have therapeutic potential.

    “these studies seem to support the idea that redox dysregulation contributes to aberrant developmental trajectories in schizophrenia and that early correction of this imbalance may have therapeutic potential 86 .”
  • The PV-cell-specific Gclc manipulation did not cause myelin deficits typically observed upon global redox dysregulation.

    “The cell-specific manipulation was subtle and did not cause myelin deficits (Figure 1D,E) typically observed upon global redox dysregulation (3, 37).”
  • Redox dysregulation, an imbalance between oxidative stress and antioxidant defense, may contribute to schizophrenia pathogenesis.

    “Mounting evidence also indicates that “redox dysregulation,” an imbalance between oxidative stress and antioxidant defense systems, may play a role in the pathogenesis (reviewed in ref. (3)).”
  • Mis-timed developmental trajectories of brain plasticity may contribute in part to the etiology of mental illnesses involving oxidative stress, such as schizophrenia.

    “Mis-timed developmental trajectories of brain plasticity may therefore contribute in part to the etiology of mental illnesses involving oxidative stress, such as schizophrenia (2, 3, 18).”

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.
