Host Immune Response to ZIKV in an Immunocompetent Embryonic Mouse Model of Intravaginal Infection
Zika virus (ZIKV) only induces mild symptoms in adults; however, it can cause congenital Zika syndrome (CZS), including microcephaly. Most of the knowledge on ZIKV pathogenesis was gained using immunocompromised mouse models, which do not fully recapitulate human pathology. Moreover, the study of th...
