Prenatal immune challenge compromises the normal course of neurogenesis during development of the mouse cerebral cortex

Abstract

Maternal infection during pregnancy is an environmental risk factor for the development of severe brain disorders in offspring, including schizophrenia and autism. However, little is known about the neurodevelopmental mechanisms underlying the association between prenatal exposure to infection and the emergence of cognitive and behavioral dysfunctions in later life. By injecting viral mimetic polyriboinosinic‐polyribocytidylic acid (Poly I:C) into mice, we investigated the influence of maternal immune challenge during pregnancy on the development of the cerebral cortex of offspring. Our previous study showed that stimulation of the maternal immune system compromised the expression properties of transcription factors and the synaptogenesis of cortical neurons in upper layers but not those in deeper layers. The objective of the current study was to examine further whether maternal immune challenge has an influence on the cellular–biological features of the cortical progenitors that generate distinct cortical neuronal subtypes. We found the following abnormalities in the cortex of mice given the prenatal Poly I:C injection during later stages of cortical neurogenesis. First, proliferative activity and the expression of Pax6, which is a master regulator of the gene expression of transcription factors, were significantly decreased in the cortical progenitors. Second, the laminar allocation and gene expression were significantly altered in the daughter neurons generated at the same birth dates. These results demonstrate that specific abnormalities in the cortical progenitors preceded deficits in neuronal phenotypes. These changes may underlie the emergence of psychiatric brain and behavioral dysfunctions after in utero exposure to an infection. © 2011 Wiley‐Liss, Inc.

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.
