Rat model of glucocorticoids exposure during gestation has shown reduction in brain weight. At P7, alterations of cerebral metabolism in the cortex and the hippocampus have been observed by in vivo 1H-MRS. Lactoferrin (Lf) is an iron-binding glycoprotein secreted in milk which has an antioxidant activity. The aim of this work was to evaluate the neuroprotective effect of Lf following prenatal exposure to glucocorticoids by high field localized 1H-MRS. Neurochemical profiles of the pup rat brains confirmed the altered brain development after Dex exposure and revealed the potential protective effect of Lf given to gestational and lactating dams.
