MicroRNA expression profile in CHME3 cells infected with Japanese encephalitis virus

ABSTRACT: CHME3 cells grown on six-wells were infected with Japanese encephalitis virus (JEV) (P20778 strain), and total RNA was isolated from cells at 6, 24 and 48 h of post infection. MicroRNA expression was significantly altered in JEV-infected human microglial cells. A time-dependent change in microRNA profile was noted. Bioinformatics analysis identified anti-correlation between differentially expressed miRNAs and the gene expression at different time point which ultimately affected several signalling pathways in microglia cells. Brain-enriched microRNAs and a set of microRNA previously designated as NeurimmiRs were also differentially expressed in response to JEV infection.

Ribosome profiling of Japanese encephalitis virus infected Neuro2a cells

Project description:Ribosome profiling (Ribo-Seq) and RNA-Seq analysis of mouse neuroblastoma (Neuro2a) cells infected with Japanese Encephalitis Virus (JEV) P20778 Vellore strain. At 18 h post infection (p.i.), infected cells were treated with either cycloheximide (translation elongation inhibitor) or in combination with harringtonine (translation initiation inhibitor). Ribo-Seq libraries were prepared using a broad range of fragment lengths (25 to 70 nucleotides) and deep sequenced. This allowed for estimation of ribosomal frameshifting efficiency and discovery of a novel upstream open reading frame (uORF) in JEV along with perturbations in ribosome-associated tRNA levels upon JEV infection.

Transcriptome Profiling of Japanese Encephalitis Virus (JEV) Infected Human Neuroepithelioma Cells (SK-N-MC)

Project description:Japanese Encephalitis (JE) is an important causal of viral encephalitis in Eastern and Southeast Asia. Neuronal injury and varying degrees of neuroinflammation are often pathological hallmarks of JE, which result in high morbility and mortality rates. However, a clear understanding on neuron cells' responses to JEV infection remains elusive. This study, therefore, utilized the Affymetrix Human PrimeView array for a robust profiling of JEV infected SK-N-MC cells during the active phase of infection in order to investigate the molecular details of the host cell responses.

Label-Free Proteomics-based analysis of peripheral nerve injury induced by Japanese encephalitis virus

Project description:Japanese encephalitis (JE) is an acute encephalitis syndrome contributed to Japanese encephalitis virus (JEV) infection. It is the chief cause of viral encephalitis in Asian. In recent years, association of JEV infection with neurological problems such as Guillain-Barré syndrome had reported. Nevertheless, its potential pathogenic mechanism has never been reported. Therefore, it is urgent to explore the relationship between peripheral nerve injury and JEV infection. Here, we use the liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique to make out the protein expression levels of mice sciatic nerve between JEV infection group and the sham group. In general, 4303 proteins were identified by MS, and 187 differentially expressed proteins were found. There were 105 proteins up-regulated in the injured sciatic nerve, and 82 proteins were down-regulated. Functional enrichment analysis of differentially expressed proteins showed that the up-regulated proteins were mainly related to immune regulatory response, and the down-regulated proteins were related to ribosomal structural components and translation.

Analyses of Long Non-coding RNA and mRNA Profiles using Microarray Platform in Mice Brain during Japanese Encephalitis Virus Infection

Project description:Japanese encephalitis virus (JEV) is the leading cause of epidemic encephalitis worldwide. JEV-induced neuroinflammation is characterized by profound neuronal cells damage accompanied by activation of glial cells. Albeit long non-coding RNAs (lncRNAs) have been emerged as important regulatory RNAs with profound effects on various biological processes, it is unknown how lncRNAs regulate JEV-induced inflammation. Here, using microarray approach, we identified 618 lncRNAs and 1007 mRNAs differentially expressed in JEV-infected mice brain.

Comparison of the Human Neuronal Proteome upon Japanese Encephalitis or West Nile Virus Infection and potential role of mosquito saliva in neuropathogenesis

Project description:Neurotropic flavivirus Japanese encephalitis virus (JEV) and West Nile virus (WNV) are amongst the leading causes of encephalitis. Using label-free quantitative proteomics, we identified proteins differentially expressed upon JEV (gp-3, RP9) or WNV (IS98) infection of human neuroblastoma cells. Both viruses were associated with the up-regulation of immune response (IFIT1/3/5, ISG15, OAS, STAT1, IRF9) and the down-regulation of SSBP2, involved in gene expression, as well as PAM, involved in neuropeptide amidation. Proteins associated to membranes, involved in extracellular matrix organization and collagen metabolism represented major clusters down-regulated by JEV and WNV. Moreover, transcription regulation and mRNA processing clusters were also heavily regulated by both neurotropic flaviviruses. If the proteome of neuroblastoma cells infected by JEV or WNV was significantly modulated in the presence of mosquito saliva, both viruses showed distinct patterns. Mosquito saliva favored the modulation of proteins associated with gene regulation in JEV infected neuroblastoma cells while it was the modulation of proteins associated with protein maturation, signal transduction and ion transporters in the case of WNV infected neuroblastoma cells.

Host Genes Differentially Expressed by Virulent and Attenuated Strains of Japanese Encephalitis Virus

Project description:Japanese encephalitis virus (JEV) is a mosquito-borne flavivirus and causes acute encephalitis with high mortality rate in humans. Despite the demonstration of difference in neuroinvasiveness between JEV strains, little is known about host gene response upon infection of virulent and attenuated JEV strains. To understand the pathogenesis mechanism of JEV infection, we performed a comparative genome-wide microarray analysis (Affymetrix, mouse genome 430 2.0 with 45101 probe sets) of genes expressed in the mice brains three days post intracerebrally inoculated with JEV strains of different neurovirulence. We found that the virulent strain of JEV (RP-9) tended to affect the host gene expression more profoundly than the attenuated one (RP-2ms), as 961 vs. 665 and 655 vs. 509 genes were at least two-fold upregulated and downregulated by RP-9 and RP-2ms, respectively. In order to understand the host defense response against JEV, we further analyzed the microarray data with special focus on immune response. The expression levels of selected genes were further verified by quantitative RT-PCR at 1-, 3- and 5-day post JEV infection. The differentially regulated genes reported here likely contribute to the neurovirulent phenotype by modulating the host immunity, viral replication and/or cytotoxicity. Keywords: day3, virus (1 x 10^4 PFU), intracerebrally (ic) inoculated, brain total RNA
