Abstract

Many risk genes interact synergistically to produce schizophrenia and many neurotransmitter interactions have been implicated. We have developed a circuit-based framework for understanding gene and neurotransmitter interactions. NMDAR hypofunction has been implicated in schizophrenia because NMDAR antagonists reproduce symptoms of the disease. One action of antagonists is to reduce the excitation of fast-spiking interneurons, resulting in disinhibition of pyramidal cells. Overactive pyramidal cells, notably those in the hippocampus, can drive a hyperdopaminergic state that produces psychosis. Additional aspects of interneuron function can be understood in this framework, as follows. (i) In animal models, NMDAR antagonists reduce parvalbumin and GAD67, as found in schizophrenia. These changes produce further disinhibition and can be viewed as the aberrant response of a homeostatic system having a faulty activity sensor (the NMDAR). (ii) Disinhibition decreases the power of gamma oscillation and might thereby produce negative and cognitive symptoms. (iii) Nicotine enhances the output of interneurons, and might thereby contribute to its therapeutic effect in schizophrenia.

  • Compelling evidence suggests an imbalance between glutamatergic excitation and GABAergic inhibition in schizophrenia.

    “Compelling evidence suggests an imbalance between glutamatergic excitation and GABAergic inhibition in schizophrenia (Lisman et al., 2008; O’Donnell, 2011).”
  • In schizophrenia, NMDA receptors are believed to be hypo-functioning, and NMDA receptor inhibition reproduces many schizophrenia symptoms.

    “In schizophrenia, NMDA receptors are believed to be hypo-functioning, and the inhibition of NMDA receptors recapitulates many of the symptoms of schizophrenia [104, 122, 123].”

    From Parvalbumin interneuron vulnerability and brain disorders (2021) · cites this paper as [123]

  • NMDA receptor antagonists such as ketamine and phencyclidine can transiently reproduce key clinical features of schizophrenia and are believed to reduce PV-IN excitation.

    “NMDA receptor antagonists, such as ketamine and phencyclidine, can transiently reproduce key clinical features of schizophrenia, and are believed to reduce PV-IN excitation [123].”

    From Parvalbumin interneuron vulnerability and brain disorders (2021) · cites this paper as [123]

  • This mechanism may be linked to pathophysiology of schizophrenia and possibly accounts for some key effects of NMDAR antagonists such as ketamine.

    “This mechanism may be linked to the pathophysiology of schizophrenia (Lisman et al. 2008;Nakazawa et al. 2012) and possibly accounts for some of the key effects of NMDAR antagonists, such as ketamine, which are a leading pharmacological model of schizophrenia (Krystal et al. 1994).”
  • Elevated prefrontal E/I ratio may result from alterations in multiple pathways implicated in schizophrenia, including GABAergic deficits, increased background input from other areas, or abnormal levels of neuromodulators.

    “Elevated prefrontal E/I ratio may result from alterations in multiple pathways that are implicated in schizophrenia.These include GABAergic deficits, such as reduced GAD67 production (Lewis et al. 2005); increased background input from other areas such as the thalamus or hippocampus (Lisman et al. 2008); or abnormal levels of neuromodulators (Laruelle et al. 2003).”

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.
