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 (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.
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: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.
