Abstract

Due to the growing commercial applications of manufactured nanoparticles (NPs), toxicological studies on NPs, especially during the critical window of development, are of major importance. The aim of the study was to assess the impact of respiratory exposure to metallic and metal oxide NPs during pregnancy on lung development of the offspring and to determine the key parameters involved in lung alterations. Pregnant mice were exposed to weekly doses of 100 μg (total dose 300 μg) of titanium dioxide (TiO2), cerium oxide (CeO2), silver (Ag) NPs or saline solution by nonsurgical intratracheal instillation. The offspring lungs were analyzed at different stages of lung development: fetal stage (gestational day 17.5), pulmonary alveolarization (post-delivery day 14.5) and lung maturity (post-delivery day 49.5). Regardless of the type of NP, maternal exposure during gestation induced long-lasting impairment of lung development of the offspring. This effect was accompanied by: i) decreased placental efficiency together with the presence of NPs in placenta, ii) no increase of inflammatory mediators present in amniotic fluid, placenta or offspring lungs and iii) decreased pulmonary expression of vascular endothelial growth factor-α (VEGF-α) and matrix metalloproteinase 9 (MMP-9) at the fetal stage, and fibroblast growth factor-18 (FGF-18) at the alveolarization stage. Respiratory exposure to metallic NPs during pregnancy induces stereotyped impairment of lung development with a lasting effect in adult mice, independently of the chemical nature of the NP.

  • Gestational exposure to titanium dioxide, cerium oxide, and silver nanoparticles induced stereotyped impairment of lung development with lasting effects in adult mice, independent of nanoparticle chemical nature, indicating particle size played a primary role.

    “Paul et al. [106] showed gestational exposure to titanium dioxide (TiO2), cerium oxide (CeO2), and silver nanoparticles-induced stereotyped impairment of lung development (decreased radial alveolar count/alveolar surface) with lasting effects in adult mice. These effects were independent of the chemical nature of the nanoparticles indicating particle size played a primary role.”

  • Decreased placental efficiency with the presence of metallic nanoparticles in the placenta was confirmed in a mouse model and correlated with impaired lung development in offspring that persisted into adulthood.

    “In another mouse model, Paul et al. [106] confirmed decreased placental efficiency with the presence of metallic nanoparticles in the placenta. This correlated with impaired lung development in offspring that persisted into adulthood.”

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.
