Congenital microcephaly is among the neurodevelopmental disorders the virus can cause in newborns, and this defect has been associated with ZIKV-mediated cytopathic effects in human neural progenitor cells (hNPCs). In this study, we investigated the cellular changes that occur in hNPCs in response to ZIKV (African and Asian lineages)-induced cytopathic effects. Transmission electron microscopy showed the progress of cell death as well as the formation of numerous vacuoles in the cytoplasm of ZIKV-infected hNPCs. Infection with both African and Asian lineages of ZIKV induced apoptosis, as demonstrated by the increased activation of caspase 3\/7, 8, and 9. Increased levels of proinflammatory cytokines and chemokines (IL-6, IL-8, IL-1\u03b2) were also detected in ZIKV-infected hNPCs, while z-VAD-fmk-induced inhibition of cell death suppressed ZIKV-mediated cytokine production in a dose-dependent manner. ZIKV-infected hNPCs also displayed significantly elevated gene expression levels of the pro-apoptotic Bcl2-mediated family, in particular, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). Furthermore, TRAIL signaling led to augmented ZIKV-mediated cell death and the knockdown of TRAIL-mediated signaling adaptor, FADD, resulted in enhanced ZIKV replication. In conclusion, our findings provide cellular insights into the cytopathic effects induced by ZIKV infection of hNPCs.<\/jats:p>","DOI":"10.3390\/cells9112487","type":"journal-article","created":{"date-parts":[[2020,11,16]],"date-time":"2020-11-16T21:48:52Z","timestamp":1605563332000},"page":"2487","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Zika Virus Induces Tumor Necrosis Factor-Related Apoptosis Inducing Ligand (TRAIL)-Mediated Apoptosis in Human Neural Progenitor Cells"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9641-8473","authenticated-orcid":false,"given":"Jae Kyung","family":"Lee","sequence":"first","affiliation":[{"name":"BK21 Graduate Program, Department of Biomedical Sciences, Korea University College of Medicine, Seoul 08308, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji-Ae","family":"Kim","sequence":"additional","affiliation":[{"name":"BK21 Graduate Program, Department of Biomedical Sciences, Korea University College of Medicine, Seoul 08308, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5423-0440","authenticated-orcid":false,"given":"Soo-Jin","family":"Oh","sequence":"additional","affiliation":[{"name":"BK21 Graduate Program, Department of Biomedical Sciences, Korea University College of Medicine, Seoul 08308, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5156-0003","authenticated-orcid":false,"given":"Eun-Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Metabolic Regulation Research Center, Korea Research Institute of Bioscience and Biotechnology (KRIBB), Daejeon 34141, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ok Sarah","family":"Shin","sequence":"additional","affiliation":[{"name":"BK21 Graduate Program, Department of Biomedical Sciences, Korea University College of Medicine, Seoul 08308, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"509","DOI":"10.1016\/0035-9203(52)90042-4","article-title":"Zika virus.
