Abstract

Inflammatory and immunological processes interfering with brain development are discussed as one cause of schizophrenia. Various signs of overactivation of the immune system were often found in this disease. Based on post-mortem analysis showing an increased number of activated microglial cells in patients with schizophrenia, it can be hypothesized that these cells contribute to disease pathogenesis and may actively be involved in gray matter loss observed in such patients. In the present study, PolyI:C incubation of pregnant dams was used as animal model of schizophrenia, and the number and shape of microglia were assessed in the offspring in the early phase of this disease, using fluorescence immunostaining (Iba1). Descendants of mice exposed to PolyI:C at embryonic day 9 showed higher number of microglial cells in the hippocampus and striatum, but not in the frontal cortex at postnatal day 30, which is similarly to adolescence in man, as compared to those exposed to saline. Furthermore, offspring microglia from PolyI:C treated mothers were morphologically characterized by a reduced arborization indicative for a status of higher activation compared to the offspring microglia from vehicle treated mice. This study supports the hypothesis that maternal infection during embryogenesis contributes to microglial activation in the offspring, which may therefore represent a contributing factor to the pathogenesis of schizophrenia and underlines the need for new pharmacological treatment options in this regard.

  • Schizophrenia neuropathology has been reported to be closely associated with cytokines and microglial activation.

    “In this context, the neuropathology of schizophrenia has been reported to be closely associated with cytokines and microglial activation (Bayer et al., 1999; Brown, 2011; Juckel et al., 2011; Meyer et al., 2009; Monji et al., 2009; Najjar et al., 2013; Radewicz et al., 2000; Vuillermot et al., 2010).”

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.
