Abstract

Maternal infection during pregnancy increases the risk for neurodevelopmental disorders such as schizophrenia and autism in the offspring. This association appears to be critically dependent on the precise prenatal timing. However, the extent to which distinct adult psychopathological and neuropathological traits may be sensitive to the precise times of prenatal immune activation remains to be further characterized. Here, we evaluated in a mouse model of prenatal immune challenge by the viral mimic, polyriboinosinic-polyribocytidilic acid (PolyIC), whether prenatal immune activation in early/middle and late gestation may influence the susceptibility to some of the critical cognitive, pharmacological, and neuroanatomical dysfunctions implicated in schizophrenia and autism. We revealed that PolyIC-induced prenatal immune challenge on gestation day (GD) 9 but not GD17 significantly impaired sensorimotor gating and reduced prefrontal dopamine D1 receptors in adulthood, whereas prenatal immune activation specifically in late gestation impaired working memory, potentiated the locomotor reaction to the NMDA-receptor antagonist dizocilpine, and reduced hippocampal NMDA-receptor subunit 1 expression. On the other hand, potentiation of the locomotor reaction to the dopamine-receptor agonist amphetamine and reduction in Reelin- and Parvalbumin-expressing prefrontal neurons emerged independently of the precise times of prenatal immune challenge. Our findings thus highlight that prenatal immune challenge during early/middle and late fetal development in mice leads to distinct brain and behavioral pathological symptom clusters in adulthood. Further examination and evaluation of in utero immune challenge at different times of gestation may provide important new insight into the neuroimmunological and neuropathological mechanisms underlying the segregation of different symptom clusters in heterogeneous neuropsychiatric disorders such as schizophrenia and autism.

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.
