Zika Virus Hijacks Placental Tunnels to Evade Immune Defense

Infection with Zika virus in pregnancy can lead to neurological disorders, fetal abnormalities and fetal death. Until now, how the virus manages to cross the placenta, which nurtures the developing fetus and forms a strong barrier against microbes and chemicals that could harm the fetus, has not been clear.
