ABSTRACT
Objective To identify the infection and the replication of Tick-borne encephalitis virus(TBEV) in human neuroblastoma cells.Methods After being inffected with TBEV,the cell culture supernatant of human neuroblastoma cell line SK-N-SH was collected and assayed at different time points.Byusing real-time RT-PCR and plaque assay to measure the titer of virus in the supernatant,the replication andproliferation of TBEV in human neuroblastoma cell was identified.Meanwhile,the morphological change of SK-N-SH after TBEV infection was also visualized by observation under microscope and immunmquorescenceassay.Results Real-time RT-PCR and plaque assay both demonstrated that TBEV could replicate effectively in SK-N-SH cells,the peak titer could reach 2.92× 107 PFU/ml on 3 days post-inoculation.And significant morphological change occured on infected SK-N-SH cells after 2 days post inoculation.By immunofluorescence assay,the virus particles could be detected and visualized.Conclusion TBEV can replicate andproliferate effcctively and cause significant cell morphological changes in human neuroblastoma cell SK-N-SH,which demonstrated that SK-N-SH could be a suitable cell model for TBEV culture.
