Prenatal exposure to Zika virus shapes offspring neutrophil function in a sex-specific manner.

ABSTRACT: Maternal viral infection during pregnancy can have lasting consequences on offspring immune development. Zika virus (ZIKV) is known to trigger maternal immune activation (MIA), yet its impact on fetal and postnatal innate immunity remains poorly understood. Here, we investigate how prenatal exposure to ZIKV influences offspring neutrophil function using a murine model of maternal infection. We identify a sex-dimorphic placental response to ZIKV and observed hyperinflammation in ZIKV-exposed male offspring following LPS challenge. Functional assays reveal impaired reactive oxygen species production and defective neutrophil extracellular trap formation in neutrophils from ZIKV-exposed offspring. Furthermore, we identify A20 as a key sex-dimorphic regulator of neutrophil activation and surviv
