Project description:Utilisation of RNA-binding proteins (RBPs) is an important aspect of post-transcriptional regulation of viral RNA. Viruses such as influenza A viruses (IAV) interact with RBPs to regulate processes including splicing, nuclear export and trafficking, while also encoding RBPs within their genomes, such as NP and NS1. But with almost 1000 RBPs encoded within the human genome it is still unclear what role, if any, many of these proteins play during viral replication. Using the RNA interactome capture (RIC) technique, we isolated RBPs from IAV infected cells to unravel the RBPome of mRNAs from IAV infected human cells. This led to the identification of one particular RBP, MKRN2, that associates with and positively regulates IAV mRNA. Through further validation, we determined that MKRN2 is involved in the nuclear-cytoplasmic trafficking of IAV mRNA likely through an association with the RNA export mediator GLE1. In the absence of MKRN2, IAV mRNAs accumulate in the nucleus of infected cells, which we suspect leads to their degradation by the nuclear RNA exosome complex. MKRN2, therefore, appears to be required for the efficient nuclear export of IAV mRNAs in human cells.

Project description:Two rounds of TMT relative quantitative proteomics were performed to detect cellular factors involved in p-eIF4E regulation of the synthesis of viral proteins.our first round of screening identified differentially expressed proteins in PEDV-infected cells and mock-infected cells; the cellular pathways involved were mainly the estrogen, cAMP, and calcium signaling pathways. Second round screening identified differentially expressed proteins in the PEDV-infected S209A-Vero cells vs. the PEDV-infected WT-Vero cells; the regulated cellular pathways were found to be mainly in the PI3K-Akt, focal adhesion, and mTOR signaling pathways, and the biological processes and molecular functions in which p-eIF4E played a role were related mainly to metabolism and biogenesis, catalytic activity, and stimuli response.4006 host factors were detected, of which 193 (in brown) were significantly upregulated (ratio ≥1.2, P＜0.05) and 191 (in green) were down-regulated upon PEDV infection (ratio ≤0.83, P＜0.05). 29 of the 191 down-regulated proteins were susceptible to a low level of p-eIF4E . Notably, among the 193 upregulated cellular proteins, 77 were upregulated in the WT-Vero over the S209A-Vero cells , suggesting that the WT-Vero cells are more susceptible to a high level of p-eIF4E.

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:Zika virus (ZIKV) is a mosquito-transmitted positive-sense RNA virus in the family Flaviviridae. Candidate live-attenuated vaccine (LAV) viruses with engineered deletions in the 3’UTR provide immunity and protection in animal models of ZIKV infection, and phenotypic studies show that LAVs retain protective abilities following in vitro passage. The present study investigates the genetic diversity of wild-type (WT) parent ZIKV and its candidate LAVs using next generation sequencing analysis of five sequential in vitro passages. ZIKV RNA from was transfected into Vero cells, incubated for nine days, harvested, and clarified by centrifugation to generate passage 0 (P0) ZIKV infectious clones. Subsequently, P0 ZIKVs were blind-passaged into fresh cultures to generate P1, then serially through P5. P1-P5 stocks were harvested from cell media at 4-5 days post-infection. ZIKV RNA from 3’UTR deletion mutants were transfected into Vero cells, incubated for nine days, harvested, and clarified by centrifugation to generate passage 0 (P0) ZIKV infectious clones. Subsequently, P0 ZIKVs were blind-passaged into fresh cultures to generate P1, then serially through P5. P1-P5 stocks were harvested from cell media at 4-5 days post-infection. Genetic diversity of the viruses were assessed by evaluating both the variability (or uncertainty) at each nucleotide position was determined using Shannon entropy calculations and identified single nucleotide variants (SNVs). The results showed both the parental WT and LAV derivatives increase in genetic diversity with evidence of adaptation following passage.

Project description:Zika virus is a global public health emergency due to its association with microcephaly, Guillain-Barré syndrome, neuropathy, and myelitis in children and adults. A total of 87 countries have had evidence of autochthonous mosquito-borne transmission of Zika virus, distributed across four continents, and no antivirus therapy or vaccines are available. Therefore, several strategies have been developed to target the main mosquito vector, Aedes aegypti, to reduce the burden of different arboviruses. Among such strategies, the use of the maternally-inherited endosymbiont Wolbachia pipientis has been applied successfully to reduce virus susceptibility and decrease transmission. However, the mechanisms by which Wolbachia orchestrate resistance to ZIKV infection remains to be elucidated. In this study, we apply quantitative isobaric mass spectrometry-based proteomics to quantify proteins and identify pathways altered during ZIKV infection; Wolbachia infection; co-infection with Wolbachia/ZIKV in the Ae. aegypti. We show that Wolbachia regulates proteins involved in ROS production, regulates humoral immune response, and antioxidant production. The reduction of ZIKV polyprotein in the presence of Wolbachia in the mosquitoes was determined by mass spectrometry and corroborates the idea that Wolbachia helps to block ZIKV infections in Ae. aegypti. The present study offers a rich resource of data to help elucidate mechanisms by which Wolbachia orchestrate resistance to ZIKV infection in Ae. aegypti.

Project description:Zika virus (ZIKV) infection has caused severe unexpected clinical outcomes in neonates and adults during the recent outbreak in Latin America, particularly in Brazil. Congenital malformations associated with ZIKV have been frequently reported; nevertheless, the mechanism of vertical transmission and the involvement of placental cells remains unclear. In this study, we applied quantitative proteomics analysis in a floating explant model of chorionic villi of human placental tissues incubated with ZIKV and with ZIKV pre-adsorbed with anti-ZIKV envelope protein. The regulation of specific proteins was measured using immunofluorescence and immunoperoxidase assays. Altered levels of proteins were involved in cell proliferation, apoptosis, inflammatory processes, and the integrin-cytoskeleton complex. Antibody-opsonized ZIKV particles differentially modulated the pattern of protein expression in placental cells; this phenomenon may play a pivotal role in determining the course of infection and the role of mixed infections. These data fill gaps in our understanding of ZIKV in the placenta and help identify infection control targets.
