Project description:Zika virus (ZIKV) infection at the maternal-placental interface is associated with adverse pregnancy outcomes including fetal demise and pregnancy loss. To determine how infection impacts placental trophoblasts, we utilized rhesus macaque trophoblast stem cells (TSC) that can be differentiated into early gestation syncytiotrophoblasts (ST) and extravillous trophoblasts (EVT). TSCs and STs, but not EVTs, were highly permissive to productive infection with ZIKV strain DAK AR 41524. The impact of ZIKV on the cellular transcriptome showed that infection of TSCs and STs increased expression of immune related genes, including those involved in type I and type III interferon responses. ZIKV exposure altered extracellular vesicle (EV) protein, mRNA, and miRNA cargo, regardless of productive infection. These findings suggest that early gestation macaque TSCs and STs are permissive to ZIKV infection, and that EV analysis may provide a foundation for identifying non-invasive biomarkers of placental infection in a highly translational model.

Project description:Zika virus (ZIKV) infection of maternal and placental cells at the maternal-fetal interface is associated with a spectrum of adverse pregnancy outcomes including fetal demise and pregnancy loss. Trophoblast cell types that comprise the placenta include cytotrophoblasts, syncytiotrophoblasts (STs), and extravillous trophoblasts (EVTs). To determine which trophoblast cells are permissive to ZIKV and to understand how infection impacts cellular gene expression, we utilized a macaque in vitro trophoblast stem cell (TSC) model. TSCs were derived from primary cytotrophoblasts and represent a proliferative trophoblast that can be differentiated into STs and EVTs. TSCs and ST3Ds (STs grown in suspension) were highly permissive to infection with ZIKV strain DAK AR 41524, whereas EVTs maintained a level of resistance to productive infection. The impact of ZIKV on cellular gene expression was determined by transcriptomic and miRNAome analysis. Infection of TSCs and ST3Ds results in increased expression of immune related genes, including those in the type I and type III interferon response. ZIKV exposure impacts EV protein, mRNA, and miRNA cargo, regardless of productive infection. Altogether, these findings suggest TSCs and STs of the macaque are permissive to ZIKV infection and that EV analysis has the potential to identify ZIKV infection. These findings provide a foundation for further ZIKV study and allow for potential ZIKV infection biomarker identification in a highly translational model.

Project description:To identify the various host factors involved in ZIKV infection, we compared the transcriptional profile for ZIKV-infected human first-trimester placenta trophoblast cell (HTR8) and glioblastoma astrocytoma (U251-MG). Our results demonstrated that the common IFN, inflammatory cytokine, and chemokine production were activated upon ZIKV infection of these two cell types while serval DEGs were enriched in distinct biological processes related to the characteristics of cell types. Our findings identified multiple host factors associated with ZIKV pathogenesis and potential treatment of congenital zika syndrome (CZS)

Project description:Zika virus (ZIKV) infection causes microcephaly and has been linked to other brain abnormalities. How ZIKV impairs brain development and function remains elusive. Here we systematically profiled transcriptomes of human neural progenitor cells (hNPCs) and astrocytes exposed to Asian ZIKVC, African ZIKVM, and Dengue virus (DENV). DENV causes distinct gene expression changes; and ZIKV has a broader impact on the expression of gene involved in DNA replication and repair. While overall expression profiles are similar, ZIKVC, but not ZIKVM, induces upregulation of viral response genes. Upon ZIKV infection, astrocytes exhibit more prominent transcriptome changes than hNPCs, particularly enriching genes related to inflammatory response and cytokine production pathways. Our analyses reveal cell-type- and strain-specific molecular signatures associated with ZIKV infection, and identify astrocytes as a major direct target of ZIKV. Further investigation of ZIKV-host interactions based our transcriptomic datasets may help to illuminate neural virulence determinants of ZIKV in patients.

Project description:Zika virus (ZIKV) infection during pregnancy results in an increased risk of spontaneous abortion and vertical transmission across placenta results in severe congenital defects in newborns. While the infectivity and pathological effects of ZIKV on the placental trophoblast progenitor cells in early human embryos remains largely unknown. Here, using the human trophoblast stem cells (hTSCs) isolated from human blastocyst, we showed that hTSCs were permissive to ZIKV infection, while resistance to ZIKV increased with differentiation. Combined CRISPR/Cas9-mediated gene knockout and RNA-seq assays, we demonstrated that the intrinsic expression of AXL and TIM-1, as well as the absence of potent interferon (IFN)-stimulated genes (ISGs), contributed to the high sensitivity of hTSCs to ZIKV. Furthermore, using our newly developed hTSC-derived 3 dimensional (3D) placental trophoblast organoid model, we demonstrated that ZIKV infection completely disrupted the structure of mature hTSC-organoids and inhibited syncytialization. Overall, our results clearly demonstrated that hTSCs represented the major target cells of ZIKV, and a possible reduced syncytialization may result from ZIKV infection of early developing placenta. These findings deepened our understanding of the characteristics and consequences of ZIKV infection of trophoblast stem cells in early human embryo.

Project description:To determine the effect of Zika virus infection on pre-implantation embryonic development, we performed single blastocyst RNA-Seq on MOCK and ZIKV infected embryos. ZIKV infection results in an increased risk of spontaneous abortion and poor intrauterine growth although the mechanisms underlying fetal loss remain undetermined. Little is known about the impact of ZIKV infection during the earliest stages of pregnancy, or pre- and peri-implantation, because most current studies of ZIKV infection in pregnancy models focus on post-implantation stages. Here, we demonstrate that trophectoderm cells of pre-implantation human and mouse embryos can be efficiently infected with ZIKV, and that trophectoderm can propagate virus causing cell death of neural progenitors. These findings were corroborated by our demonstration that hESC-derived trophectoderm cells are infected by ZIKV in a dose dependent manner. RNAseq of single blastocysts revealed key transcriptional changes in cellular and physiologic functions upon ZIKV infection, including nervous system development and function, prior to commitment to the neural cell lineage. Finally, the pregnancy rate of mice infected pre-implantation was > 50% lower than females infected at E4.5. These results demonstrate that pre-implantation ZIKV infection of trophectoderm leads to miscarriage or spontaneous abortion. Moreover, pre- and peri-implantation ZIKV infects trophectoderm cells that propagate virus over time causing cell death in neural progenitors. Cumulatively, these data demonstrate that vertical pre- and peri-implantation ZIKV infection of trophectoderm impairs fetal development and causes neural progenitor cell death, elucidating a previously unappreciated association of pre- and peri-implantation ZIKV infection and microcephaly.

Project description:Zika virus (ZIKV) has been associated with microcephaly and other brain abnormalities; however, the molecular consequences of ZIKV to human brain development are still not fully understood. Here we describe alterations in human neurospheres derived from induced pluripotent stem (iPS) cells infected with the strain of Zika virus that is circulating in Brazil. Combining proteomics and mRNA transcriptional profiling, over 500 proteins and genes associated with the Brazilian ZIKV infection were found to be differentially expressed. These genes and proteins provide an interactome map, which indicates that ZIKV controls the expression of RNA processing bodies, miRNA biogenesis and splicing factors required for self-replication. It also suggests that impairments in the molecular pathways underpinning cell cycle and neuronal differentiation are caused by ZIKV. These results point to biological mechanisms implicated in brain malformations, which are important to further the understanding of ZIKV infection and can be exploited as therapeutic potential targets to mitigate it.
