Transcriptional Profile of ZIKV Infection in HTR8 cells and U251 cells

ABSTRACT: 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)

Molecular Alterations of Extracellular Matrix in the Brain of Newborns with Congenital Zika Syndrome

Project description:Zika virus (ZIKV) infection during pregnancy could cause a set of severe abnormalities in the fetus known as congenital Zika syndrome (CZS). Experiments using animal models and in vitro systems significantly contributed to our understanding of the physiopathology of ZIKV infection. However, the molecular basis of CZS is not yet studied in humans. Here, we used a systems biology approach to integrate transcriptomic, proteomic and genomic data from post-mortem brains of neonates with CZS. We observed that collagen genes were greatly reduced in CZS brains at both the RNA and protein levels and that neonates with CZS have several polymorphisms in collagen genes associated with osteogenesis imperfect and arthrogryposis. These findings were validated using immunohistochemistry and collagen staining of ZIKV infected and non-infected samples. Additionally, it was found that cell adhesion genes that are essential for neurite outgrowth and axon guidance were up-regulated and thereby confirmed the neuronal migration defects observed. This work provided new insights into the underlying mechanisms of CZS and revealed host genes associated with CZS susceptibility.

Molecular Signatures Associated with ZIKV Exposure in Human Cortical Neural Progenitors and Astrocytes

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.

RNA-seq of hiPSCs-derived NPCs from 3 pairs of dizygotic discordant twins for Congenital Zika syndrome

Project description:Congenital Zika syndrome (CZS), caused by Zika virus (ZIKV) infection, has been associated to impairment of early brain development, particularly related to neural progenitor cells (NPCs) survival and growth. In this work we report in a high-throughput manner (RNA-Seq) the differences in the transcriptomes of hiPSCs(human induced pluripotent stem cells)-derived NPCs from 3 pairs of discordant twins for Congenital Zika syndrome (CZS). We found significant differences in the expression levels of genes relevant to the regulation of neural development between the NPCs from CZS-affected and non-affected twins, suggesting that epigenetic differences may contribute to the different susceptibilities of NPCs to ZIKV infection.

ZIKV prevents host mRNA export from the nucleus by disrupting UPF1 function

Project description:Zika virus (ZIKV) is a mosquito-borne virus that can have dramatic neurodevelopmental consequences when infection occurs in utero. Previous studies demonstrated that ZIKV downregulates the master regulator of nonsense mediated decay, UPF1. To examine whether this process contributes to disruption of neural development, we investigated the effect of ZIKV infection on UPF1 interaction with host RNA in neural progenitor cells. Here, we show that ZIKV-mediated disruption of UPF1 function in neural progenitor cells causes retention of mRNA in the nucleus, resulting in decreased protein levels of specific transcripts involved in neural differentiation.

Effect of ZIKV on pre-implantation embryos

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.

RNA sequencing of Aedes mosquitoes infected with Zika virus (ZIKV) or Dengue virus (DENV)

Project description:Zika virus (ZIKV), a pathogen of global health concern, is transmitted to humans by Aedes mosquitoes. However, the molecular interactions between the vector and the virus remain largely unexplored. We demonstrated that ZIKV and dengue virus (DENV) have similar tropism and infection kinetics in two mosquito strains with different degrees of susceptibility to infection. Comparison of Aedes aegypti’s molecular responses to ZIKV and DENV infection indicated that around 40% of the mosquito’s infection-responsive transcriptome is virus-specific. Regulated genes also included key factors of the mosquito’s anti-viral immunity, pointing to the possible involvement of the Toll innate immune pathway. Comparison of ZIKV and DENV infection-responsive transcriptome data to those for yellow fever virus and West Nile virus identified 26 genes likely to play key roles in virus infection of Aedes mosquitoes. Through reverse genetic analyses, we showed that the Toll and the Jak/Stat innate immune pathways mediate increased resistance to ZIKV infection, and the virus use vATPase and inosine-5’-monophosphate dehydrogenase as mosquito’s host factors.

Serum proteomics of infants in utero exposed to Zika virus without Congenital Zika Syndrome

Project description:In 2015, ZIKV infection attracted international attention during an epidemic in the Americas, when neurological disorders were reported in babies who had their mothers exposed to ZIKV during pregnancy. World Health Organization (WHO) epidemiological data show that 5 to 15% of neonates exposed to ZIKV in the uterus have complications included in abnormalities related to Congenital Zika Syndrome (CZS). The risk of complications after birth is not well documented, however, clinical evidence shows that 6% of babies exposed to ZIKV during pregnancy have complications present at birth, and this rate rises to 14% when medical monitoring is performed in all exposed babies, regardless of birth condition. Thus, the evaluation and monitoring of all exposed babies are of foremost importance as the development of late complications has been increasingly supported by clinical evidence. The identification of molecular markers in infants exposed to ZIKV without CZS could provide valuable means to improve their clinical monitoring. Here, we used a shotgun-proteomic approach to investigate molecular markers in the serum of infants without CZS symptoms but exposed to ZIKV intrauterine (ZIKV) compared to non-exposed controls (CTRL).
