ABSTRACT: Emerging multi-recombinant enterovirus A71 subgenogroup C1 genetic variant 2015 (C1v2015) associated with a burden of neurological manifestations in European countries
Project description:A siRNA screening using a commercially available membrane trafficking library identified Rab11 as a pro-viral host factor in motor neuron NSC34 cell line infected with EV-A71, a major causative agent of Hand, Foot and Mouth Disease (HFMD). This project aims at deciphering the role of Rab11 during EV-A71 infection by using various molecular virology and cell biology approaches. We also identified Rab11 interacting partners during EV-A71 infection by pulldown and mass spectrometry.
Project description:In this study, we aimed to adopt the transcriptome sequencing technology to obtain the different changes of transcriptome profiles after infecting with EV-A71 in human neuroblastoma cell line SH-SY5Y. And then, through systematic bioinformatics analysis, we hope to find useful clues for the pathogenesis of HFMD.
Project description:Development of a new internally controlled one-step real-time RT-PCR for the molecular detection of enterovirus A71 in Africa and Madagascar.
Project description:Non-structural 2B protein of enterovirus-A71 has reported involving in intracellular Ca2+ manipulation and altering cellular homeostasis such as inducing cell death in human SH-SY5Y cells. The aim of the study is to profile transcriptomic signature of human neuroblastoma SH-SY5Y cells altered by EV-A71 2B protein using RNA-sequencing analysis. We generated mRNA expression profiles of SH-SY5Y cells transfected with EV-A71 2B protein fused with mCherry and FLAG tag protein (2BmCherry) and mCherry as well as parental SH-SY5Y cells. We find that 7 genes including CCL2, RELB, IL32, PLAT, PTGES, PHLDA1, and TNFRSF9 are uniquely overexpressed in 2BmCherry comparing to mCherry. Moreover, there were 333 upregulated and 333 downregulated genes showed significant different expression level in 2BmCherry transcriptome in comparison with SHSY5Y transcriptome but not in mCherry vs SHSY5Y comparison. Functional analysis showed that EV-A71 2B upregulated genes involved Ca2+-related signaling pathways participating gene expression, immune response, apoptosis, and long-term potentiation (synaptic adaptation) of neuron in the transfected SH-SY5Y cells.
