Estrogen receptors in mom’s placenta critical during viral infection – Medical Xpress

Researchers at Duke and Mt. Sinai have identified a molecular mechanism that prevents a viral infection during a mother’s pregnancy from harming her unborn baby.
When a person becomes infected by a virus, their immune system sends out a chemical signal called type I interferon, which tells surrounding cells to increase their anti-viral defenses, including making more inflammation.
