Maternal infection during pregnancy can have severe consequences on fetal development and survival. Using a pigtail macaque model for Zika virus infection, researchers show that in utero exposure of a fetus to Zika virus due to maternal infection results in significantly decreased myelin formation around neurons. Myelin is a protective sheath that forms around neurons and is required for brain processing speed. This study suggests that reduced myelin resulting from Zika infection in utero is likely a contributing factor to severe deficits in brain development and microcephaly.
