Abstract

Prenatal infection is a major risk responsible for the occurrence of psychiatric conditions in infants. Mimicking maternal infection by exposing pregnant rodents to bacterial endotoxin lipopolysaccharide (LPS) also leads to major brain disorders in the offspring. The mechanisms of LPS action remain, however, unknown. Here, we show that LPS injection during pregnancy in rats, 2 days before delivery, triggered an oxidative stress in the hippocampus of male fetuses, evidenced by a rapid rise in protein carbonylation and by decreases in alpha-tocopherol levels and in the ratio of reduced/oxidized forms of glutathione (GSH/GSSG). Neither protein carbonylation increase nor decreases in alpha-tocopherol levels and GSH/GSSG ratio were observed in female fetuses. NMDA synaptic currents and long-term potentiation in CA1, as well as spatial recognition in the water maze, were also impaired in male but not in female 28-day-old offspring. Pretreatment with the antioxidant N-acetylcysteine prevented the LPS-induced changes in the biochemical markers of oxidative stress in male fetuses, and the delayed detrimental effects in male 28-day-old offspring, completely restoring both long-term potentiation in the hippocampus and spatial recognition performance. Oxidative stress in the hippocampus of male fetuses may thus participate in the neurodevelopmental damage induced by a prenatal LPS challenge.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Such augmented disruption occurs via activation of cellular redox signaling in response to infection.

    “Such augmented disruption occurs via the activation of the cellular redox signaling in response to infection [130,133].”
  • The deleterious effect of early-life immune challenge on parvalbumin interneurons could result from redox dysregulation, as maternal immune challenge transiently decreases glutathione and vitamin E levels and increases oxidative stress in the hippocampus.

    “This deleterious effect could result from a redox dysregulation as maternal immune challenge transiently decreases GSH and vitamin E levels and increase oxidative stress in the hippocampus (Lante et al., 2007).”

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.
