Zika virus infects human placental macrophages

One of Zika’s mysteries is how the virus passes from an infected mother, through the placenta, to a developing fetus. The route may not be direct either — transmission via multiple cell types may be necessary. A new study supports the possibility that placental immune cells called Hofbauer cells, which have direct access to fetal blood vessels, are one cell type involved….
