Prenatal exposure to lipopolysaccharide results in neurodevelopmental damage that is ameliorated by zinc in mice.

There is converging evidence that during pregnancy a maternal immune response to infection can cause neurodevelopmental damage. Lipopolysaccharide (LPS)-mediated induction of metallothionein (MT) and subsequent hypozincaemia has been linked to fetal brain damage. Our group has demonstrated that Zn, when co-administered with LPS in early pregnancy in mice (gestation day (GD) 8), prevents fetal malformations and neurodevelopmental deficits in offspring.
