When a woman experiences a stressful event early in pregnancy, the risk of her child developing autism spectrum disorders or schizophrenia increases. Yet how maternal stress is transmitted to the brain of the developing fetus, leading to these problems in neurodevelopment, is poorly understood.
New findings by University of Pennsylvania School of Veterinary Medicine scientists suggest that an enzyme found in the placenta is likely playing an important role. This enzyme, O-linked-N-acetylglucosamine transferase, or OGT, translates maternal stress into a reprogramming signal for the brain before birth.
