Placental cells may prevent viruses from passing from mother to baby

 "Cells of the placenta may have a unique ability to prevent viruses from crossing from an expectant mother to her growing baby and can transfer that trait to other kinds of cells, according to researchers at Magee-Womens Research Institute (MWRI) and the University of Pittsburgh School of Medicine. Their findings, published in the early online version of the Proceedings of the National Academy of Sciences, shed new light on the workings of the placenta and could point to new approaches to combat viral infections during pregnancy."
