Project description:B16F10, a murine melanoma cel line is cytolytic to JEV infection. We have identified a B16F10 cell line variant which is non-cytolytic to JEV infection. This variant cell line has two types of cells, one which is persistently infected JEV and another which is resistant to JEV infection. The JEV-resistant cells (B16F10r) were seperated from the presistently infected cells by single cell cloning. To understand the mechanism of JEV resistance microarray analysis was caried out to Identify and characterize genes differentially expressed during in uninfected/JEV-infected B16F10 and B16F10r cells.

Project description:Japanese Encephalitis Virus (JEV) modulates different proteins at different time points of infection to favour its propagation in the host cells. The dysregulation of intertwined pathways in the host has implications for virus pathogenesis. This study aims to decipher the global proteome of Japanese encephalitis infected THP-1 derived macrophages at 24 hours post-infection and 48 hours post-infection, which will further help to deduce the interwoven pathways regulated upon JEV 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.
Project description:Caco-2 cells grown on transwells were infected with Japanese encephalitis virus (JEV) and total RNA was isolated from cells at the time when trans-epithelial electrical resistance was reduced by about 50% of uninfected cells
Project description: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 mRNA expression was significantly altered in JEV infected human microglial cells. A time dependant 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

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.
