Maternal infection during pregnancy is associated with increased risk for neurodevelopmental disorders. Lipopolysaccharide (LPS) or saline was administered to rats to model maternal infection, and levels of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in maternal plasma, placenta, amniotic fluid, fetal liver/spleen, fetal brain, and cerebral cortex after birth were determined by ELISA or semiquantitative Western blot analysis. BDNF expression was significantly increased in the fetal brain (p = 0.039); NGF expression was significantly increased in neonatal cortex (p = 0.0009). Neurotrophic factor expression was also altered in other tissues of the maternal-fetal unit. Abnormal expression of neurotrophic factors represents a potential mechanism through which maternal infection increases risk for neurodevelopmental disorders. (C) 2003 Elsevier Science B.V.
