Project description:Zika virus (ZIKV) is unique among mosquito-borne flaviviruses in its ability to be sexually transmitted. The testes have been implicated as sites of long-term ZIKV replication, and our previous studies have identified Sertoli cells (SC), the nurse cells of the seminiferous epithelium that govern spermatogenesis, as major targets of ZIKV infection. To improve our understanding of the host-ZIKV interaction within human testicular cells, we analyzed ZIKV-induced proteome changes in SC and mixed seminiferous tubule cells (STC) using high-throughput liquid chromatography-tandem mass spectrometry (LC-MS/MS). We found that ZIKV infection in SC and STC induced distinct IFN-stimulated proteins and impacted pathways and functional networks associated with innate antiviral defense. IFN signaling was the most significantly enriched pathway and MX1 was the most abundant IFN-stimulated protein in both SC and STC. Increased levels of MX1 at later time points of infection coincided with diminished propagation of ZIKV in SC, whereas silencing of MX1 and IFIT1 enhanced peak ZIKV titers in SC. Furthermore, although downstream IFN-I signaling was found to be functional and restricted ZIKV replication in SC, in comparison to A549 cells, SC exhibited dampened expression of IFN-I/III-stimulated genes despite higher levels of virus progeny and IFN-I/III transcripts. Together, this study highlights the IFN-I/III response as a driver of the antiviral state that limits ZIKV infection in SC and suggests that delayed and reduced robustness of innate antiviral defense in SC may contribute to ZIKV persistence in the testes.

Project description:Whether Zika virus (ZIKV) could be transmitted via aerosol routes remains unknown. In this study, we demonstrated that aerosolized ZIKV is fully infectious in vitro and in vivo.Transcriptome analysis further revealed that genes expression related to viral process, biological regulation and immune system response were significantly changed.

Project description:Zika virus (ZIKV) causes congenital brain abnormalities and Guillain-Barre syndrome. It mainly transmits by Aedes mosquitoes, but infections also are linked to sexual transmissions. ZIKV can proliferate in human Sertoli cells (HSerC) for several weeks in vitro, suggesting that it might be a reservoir for persistent ZIKV infection. This study determined the proteomic changes in HSerC during ZIKV infections by TMT-mass spectrometry analysis. In Sertoli cells, a total of 4416 unique proteins were significantly dis-regulated across 3, 5, and 7 days after ZIKV infection. The dis-regulated proteins include enzymes, transcription regulators, transporters, kinases, peptidases, transmembrane receptors, cytokines, ion channels, and growth factors. Many of those proteins are involved in antiviral response, antigen presentation, and immune cell activation.

Project description:Zika virus (ZIKV) is a mosquito-transmitted positive-sense RNA virus in the family Flaviviridae. ZIKV infections are associated with neurodevelopmental deficiencies termed Congenital Zika Syndrome. ZIKV strains are grouped into three phylogenetic lineages: East African, West African, and Asian, which contains the American lineage. RNA virus genomes exist as genetically-related sequences. The heterogeneity of these viral populations is implicated in viral fitness, and genome diversity is correlated to virulence. This study examines genetic diversity of representative ZIKV strains from all lineages utilizing next generation sequencing (NGS). Inter-lineage diversity results indicate that ZIKV lineages differ broadly from each other; however, intra-lineage comparisons of American ZIKV strains isolated from human serum or placenta show differences in diversity when compared to ZIKVs from Asia and West Africa. This study describes the first comprehensive NGS analysis of all ZIKV lineages and posits that sub-consensus-level diversity may provide a framework for understanding ZIKV fitness during infection.

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), 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.

Project description:Using genome-wide RNA-seq to compare immunoprofiles of human sertoli cells, we show that the most prominent response to ZIKV at early stage of infection was suppression of cell growth and proliferation functional pathways. Peak virus replication was associated with induction of multiple antiviral defense pathways. Unique ZIKV-associated signatures included dysregulation of germ cell-Sertoli cell junction signaling.

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.
