Zika virus -- United States
Significance
------------
Zika virus (ZIKV) has been identified as a cause of microcephaly. However, the mechanisms by which ZIKV disrupts neurogenesis and causes microcephaly remains poorly understood. Here, we first report that ZIKV exposure causes neural progenitor cell pyroptosis, mediated by activation of caspase-1 and gasdermin D in vivo as well as in vitro, which links ZIKV to the development and progression of microcephaly. Consistent with this notion, caspase-1 deletion or treatment
