Abstract

Maternal immune activation (MIA) during pregnancy has been linked to an increased risk of developing psychiatric pathologies in later life. This link may be bridged by a defective microglial phenotype in the offspring induced by MIA, as microglia have key roles in the development and maintenance of neuronal signaling in the central nervous system. The beneficial effects of the immunomodulatory treatment with minocycline on schizophrenic patients are consistent with this hypothesis. Using the MIA mouse model, we found an altered microglial transcriptome and phagocytic function in the adult offspring accompanied by behavioral abnormalities. The changes in microglial phagocytosis on a functional and transcriptional level were similar to those observed in a mouse model of Alzheimer's disease hinting to a related microglial phenotype in neurodegenerative and psychiatric disorders. Minocycline treatment of adult MIA offspring reverted completely the transcriptional, functional and behavioral deficits, highlighting the potential benefits of therapeutic targeting of microglia in psychiatric disorders.

  • Commensal symbiotic bacteria are critical for proper microglial maturation, and induction of infection in pregnant dams can have disruptive effects on the progression of microglial development in offspring.

    “While commensal symbiotic bacteria are critical for proper microglial maturation, induction of infection in pregnant dams can have disruptive effects on the progression of microglial development in offspring (Pratt et al., 2013; Matcovitch-Natan et al., 2016; Mattei et al., 2017).”

  • Maternal immune activation by polyI:C can disrupt pre-microglial development in offspring, leading to a more advanced developmental stage.

    “Maternal immune activation (MIA) by administration of polyinosinic:polycytidylic acid (polyI:C), which is a synthetic analog of double-stranded RNA used to simulate viral infections via interaction with TLRs, can disrupt pre-microglial development in offspring, leading to a more advanced developmental stage.”
  • Hippocampal microglia from polyI:C offspring show dysregulated genes related to inflammatory response, cell migration, and phagocytosis.

    “Hippocampal microglial cells from polyI:C offspring mice showed dysregulation of genes associated with inflammatory response, cell migration and phagocytosis [13, 59, 60].”
  • Microglia from polyI:C offspring have reduced expression of PU.1 and its target genes, and minocycline restores this expression.

    “Microglia from polyI:C offspring had reduced expression of PU.1 and its target genes, which were restored after administration of anti-inflammatory drug minocycline [26, 59].”

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.
