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 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:Elevated palmitic acid, a most abundant saturated fatty acid, is a risk factor for obesity complications. Here, we report that palmitic acid impairs spermatogenesis by inducing abnormal palmitoylation in Sertoli cells. Firstly, we proposed a correlation between palmitic acid and spermatogenesis by reporting a significant elevation of serum palmitic acid levels in patients with dyszoospermia. In palmitic acid -treated mice, the blood-testis barrier was found to be disrupted, and decreased tight junction protein expression was observed in palmitic acid-treated Sertoli cells. Palmitic acid entered the endoplasmic reticulum and induced endoplasmic reticulum stress, resulting in damage to Sertoli cell barriers.

Project description:Zika virus (ZIKV) is a mosquito-borne flavivirus that caused an epidemic in the Americas in 2016 and is linked to severe neonatal birth defects, including microcephaly and spontaneous abortion. To better understand the host response to ZIKV infection, we adapted the 10x Genomics Chromium single cell RNA sequencing (scRNA-seq) assay to simultaneously capture viral RNA and host mRNA. Using this assay, we profiled the antiviral landscape in a population of human moDCs infected with ZIKV at the single cell level. The bystander cells, which lacked detectable viral RNA, expressed an antiviral state that was enriched for genes coinciding predominantly with a type I interferon (IFN) response. Within the infected cells, viral RNA negatively correlated with type I IFN dependent and independent genes (antiviral module). We modeled the ZIKV specific antiviral state at the protein level leveraging experimentally derived protein-interaction data. We identified a highly interconnected network between the antiviral module and other host proteins. In this work, we propose a new paradigm for the antiviral response to a specific virus, combining an unbiased list of genes that highly correlate with viral RNA on a per cell basis with experimental protein interaction data. Our ZIKV-inclusive scRNA-seq assay will serve as a useful tool to gaining greater insight into the host response to ZIKV and can be applied more broadly to the flavivirus field.

Project description:Although dendritic cells (DCs) are among the human cell population best equipped for cell-intrinsic antiviral immune defense, they seem highly susceptible to infection with Zika Virus (ZIKV). Using highly-purified mDC isolated from individuals with naturally-acquired acute infection, we here show that ZIKV induces profound perturbations of transcriptional signatures relative to uninfected patients. Interestingly, we noted a remarkable downregulation of antiviral Interferon-stimulated genes and innate immune sensors, suggesting that ZIKV can actively suppress Interferon-dependent immune responses. In contrast, several host factors known to support ZIKV infection were strongly upregulated during natural ZIKV infection; these transcripts included AXL, the main entry receptor for ZIKV, SOCS3, a negative regulator of ISG expression, and IDO-1, a recognized inducer of regulatory T cell responses. Thus, during in vivo infection, ZIKV can transform the transcriptome of dendritic cells in favor of the virus to render these cells highly conducive to ZIKV infection.

Project description:Zika virus (ZIKV) is an emerging virus causally linked to neurological disorders, including congenital microcephaly and Guillain–Barré syndrome. There are currently no targeted therapies for ZIKV infection. To identify novel antiviral targets and to elucidate the mechanisms by which ZIKV exploits the host cell machinery to support sustained replication, we analyzed the transcriptomic landscape of human microglia, fibroblast, embryonic kidney, and monocyte-derived macrophage cell lines before and after ZIKV infection.

Project description:<p>Sertoli cell-only syndrome is severe form of human male infertility in which most seminiferous tubules appear to lack all spermatogenic cells, including spermatogonial stem cells (SSCs). However, a few small tubule segments of some patients have active spermatogenesis and, thus, functional stem cell niches and SSCs. Normally SSCs replicate, migrate and refill adjacent empty niches, but this does not appear to occur in SCO syndrome. We hypothesized that this failure occurs because most niches are dysfunctional. As Sertoli cells are essential to formation of these niches, we used RNAseq to compare the transcriptomes of human testes with qualitatively normal (complete) spermatogenesis (n=4) with the transcriptomes of human testes with SCO syndrome (n=7). We then focused our analysis on the expression of transcripts that bioinformatic analyses identified as Sertoli cell signature transcripts. Results show that Sertoli cells in SCO testes express abnormally low levels of GDNF, FGF8 and BMP4, all of which are important regulators of mouse SSCs and/or progenitor spermatogonia. Sertoli cells in SCO testes express significantly reduced levels of transcripts for proteins that polarize the Sertoli cell plasma membrane and regulate the trafficking of cell adhesion and gap junction proteins in and out of that plasma membrane.</p>

Project description:Zika virus (ZIKV) is an emerging mosquito-borne flavivirus that causes severe outbreaks in human populations. ZIKV infection leads to the accumulation of small non-coding viral RNAs (known as sfRNAs) that are crucial for evasion of antiviral responses and for viral pathogenesis. However, the mechanistic understanding of how sfRNAs function remains incomplete. Here, we use recombinant ZIKVs and ribosome profiling of infected human cells to show that sfRNAs block translation of antiviral genes. Mechanistically, we demonstrate that specific RNA structures present in sfRNAs trigger PKR activation, which instead of limiting viral replication, enhances viral particle production. Although ZIKV infection induces mRNA expression of antiviral genes, translation efficiency of type I interferon and interferon stimulated genes were significantly downregulated by PKR activation. Our results reveal a novel viral adaptation mechanism mediated by sfRNAs, where ZIKV increases its fitness by repurposing the antiviral role of PKR into a proviral factor.
