Two mouse models of Zika virus infection in pregnancy have been developed by a team of researchers at Washington University School of Medicine in St. Louis. In them, the virus migrated from the pregnant mouse’s bloodstream into the placenta, where it multiplied, then spread into the fetal circulation and infected the brains of the developing pups.
The models provide a basis to develop vaccines and treatments, and to study the biology of Zika virus infection in pregnancy.
