Project description:Enterovirus 71 (EV71) and Coxsackievirus A16 (CA16) are the predominant etiological agents of hand, foot, and mouth disease (HFMD) and both belong to the human enterovirus A species of the Picornaviridae family. These viruses share similar genetic homology, although the clinical manifestations of HFMD caused by the two viruses have some discrepancies. Furthermore, the underlying mechanisms leading to these differences remain unclear. microRNAs (miRNAs) participate in numerous biological or pathological processes, including host responses to viral infections, by targeting messenger RNAs (mRNAs) for translational repression or degradation. Here, we focused on differences in miRNA expression patterns in peripheral blood mononuclear cells (PBMCs) of rhesus monkeys infected with EV71 or CA16 at different time points using high-throughput sequencing technology. For the first time, this study demonstrated that EV71 and CA16 infection result in specific miRNA expression patterns in PBMCs.

Project description:Enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are major causative agents for hand, foot and mouth disease (HFMD). In China, more than 70,756 children were infected and 40 died from the disease in recent years. This study aimed to develop a protein chip that can simultaneously detect and differentiate the antibodies induced by EV71 and CA16 simultaneously. The structure protein vp1 and vp3 from the two viruses were purified and spotted onto an aldehyde groupmodified glass slide at 1mg/ml. After that, the protein chip was reacted with the corresponding positive serum against these viruses, hybridized with a Cy3-labeled secondary antibody and scanned using the popular GenePix 4000B Microarray Scanner. In this study, Both IgG and IgM serum antibody to EV71 and CA16 were detected using protein Chip. The results showed that this method could hybridize specifically with the corresponding antibodies with strong signals and without cross-hybridization. The data also confirmed the proposed method's specificity, sensitivity, and convenience. In conclusion, this protein chip can be used to differentiate the antibodies induced by the EV71and CA16.

Project description:MicroRNA (miRNA) has been highlighted in pathogen-host interactions, however, little is known about roles of miRNAs in neurological pathogenesis of human enterovirus 71 (HEV71) infections. In this study, the comprehensive miRNA expression profiling in HEV71-infected human neuroblastoma SH-SY5Y cells were performed to identify cellular miRNAs response to HEV71. A total of 69 miRNAs were differentially expressed in HEV71-infected SH-SY5Y cells compared to non-infected cells. These findings provide new information on the miRNA and mRNA profiles in HEV71 infection, which may serve as a basis for further investigation into the biological functions of miRNAs in the neurological pathogenesis of HEV71 infections. Human neuroblastoma SH-SY5Y cells were infected with HEV71. After infection, the cells were harvested and extracted total RNA for miRNA profiling by hybridization on Affymetrix microarrays. A total of 69 miRNAs were differentially expressed inHEV71-infected SH-SY5Y cells compared to non-infected cells.

Project description:Today, the pathogenesis of human enterovirus type 71 (HEV71) infection in human central neural system remains unclear. HEV71 is the major pathogen of hand-foot-and-mouth disease (HFMD), and has been associated with severe neurological disease and even death in infants and young children. We employed the human whole genome microarray analyze the mRNA profiling in human neuroblastoma cells SH-SY5Y infected with HEV71 after transfection. Firstly, SH-SY5Y cells were transfected wtih miR-1246 inhibitor and negtive control respectively using HiPerFect Transfection Reagent according to the manufacturer’s instructions. Then the cells were infected with HEV71 after transfection. After 12 hours infection, the cells were harvested to microarray analysis. The results showed the altered expression of mRNAs including up-regulated genes and down-regulated genes. Overall, this finding will help to understand the functional genes in HEV71-infected human neuroblastoma cells and miR-1246-virus-host interaction.

Project description:We have previously shown that Heparin (Hep) significantly inhibited Enterovirus 71 (EV71) infection and binding in both Vero and a human neural cell line, SK-N-SH, in vitro. Therefore, in this study we intended to gain insight into the cellular and molecular mechanisms of action of Hep against clinical EV71 infection in SK-N-SH cells. Instead of stating a long list of gene functions and pathways, we tried to select for EV71-induced genes that were exclusively affected by antiviral activity of Hep through a multi-level comparison and characterization. Overall, our microarray analysis may suggest that Hep might exert its anti-EV71 activity in SK-N-SH cells, at least in part, through the following mechanisms: i. Reduction of the down-regulation effect of EV71 on TOX that would lead to an increased population of effective, mature T-cells and NK-cells; ii. Reduction of the up-regulation effect of EV71 on GIP, that in turn, would reduce recruiting different GPCRs, leading to a reduced viral infection in host cells; iii. Partially neutralization of the EV71-mediated apoptosis through expression of CARP2 that acts as an anti-apoptosis ubiquitin protein ligase (E3). EV71 is a neurovirological virus that can sometimes cause severe and fatal CNS complications in infected patients. Since still there is no approved drug for prophylaxis of EV71-casued disease, discovering a molecular drug target(s) for EV71 infection would be crucial. This was the first study to report direct assessment of mechanisms of action of antivirals against EV71 infection. SK-N-SH cells were infected with a clinical EV71 isolate followed by treatment with 125 µg/mL of Hep. At 72 hours post infection, antiviral activity and cytotoxicity of Hep at 125 µg/mL in 12-well plates were carried out at the same time as RNA extraction. This way, we could ensure that we would assess transcript profiles of the host cells under the same condition and time as assessment of antiviral activity and cytotoxicity for the same replicates. Changes in expression profiles of the host cells were comparatively assessed under four conditions: cell control (neither infection nor treatment, designated CC), treated only with Hep (compound control, designated Cyto), EV71-infected cells treated with Hep (treatment, designated H), and infected with EV71 without treatment with Hep (virus control, designated V). All experiments were applied in triplicate, and totally twelve GeneChip® Human Gene 1.0 ST arrays were purchased from Affymetrix and processed. Then, the following five contrasts were made: Hep vs. CC; VC vs. CC; Cyto vs CC; Hep vs. VC; and Hep vs. Cyto. For each contrast, only samples from the two target groups were included. The statistical parameters of ANOVAs, p values, multiple test corrections, and fold changes were calculated within each contrast. Then, a multi-level selection and analysis procedure was employed in order to attribute changes in the gene transcription level to antiviral activity of Hep.
