Abstract

Significance: Particulate matter exposure causes infant respiratory morbidity and mortality, but the role of ultrafine particles (UFPs) with an aerodynamic diameter of less than 0.1 μm in asthma and respiratory tract infections is unclear. Limited mechanistic information is available concerning UFP influence on the etiology of childhood asthma or susceptibility to respiratory infections. Here we exposed two strains of mice (sensitive to oxidative stress or allergen exposure) to UFPs throughout gestation at concentrations relevant to human exposures. Our results reveal a window of pulmonary immunosuppression in offspring following in utero UFP exposure. A dampened host immune response during early development underlies increased childhood susceptibility to respiratory infections, highlighting the necessity to develop strategies to protect the fetus during this vulnerable period.

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.
