How Pregnancy Turns the Stress Response on Its Head

Immune cells in the uterus and placenta of stressed pregnant mice were not activated, but researchers found increased levels of inflammation in the developing fetal brain. Additionally, prenatal stress led to reductions in gut microbial strains and functions, especially in those linked to inflammation.
