Maternal magnesium sulfate fetal neuroprotective effects to the fetus: inhibition of neuronal nitric oxide synthase and nuclear factor kappa-light-chain-enhancer of activated B cells activation in a rodent model

Lipopolysaccharide-simulated inflammation during pregnancy may cause brain injury through activation of neuronal nitric oxide synthase and nuclear factor kappa-light-chain-enhancer of activated B cells pathways and, potentially, production of excitotoxic nitric oxide and inflammatory mediators. The increased susceptibility to brain injury in preterm fetuses may be due to enhanced nuclear factor kappa-light-chain-enhancer of activated B cells activation. Magnesium sulfate protective effects may be secondary, in part, to inhibition of neuronal nitric oxide synthase and nuclear factor kappa-light-chain-enhancer of activated B cells activation and decrease proinflammatory cytokine production through blocking nuclear factor kappa-light-chain-enhancer of activated B cells receptors.
