Tick-borne encephalitis virus inhibits rRNA synthesis and host protein production in human cells of neural origin
 SELINGER, Martin
Tick-borne encephalitis virus (TBEV), a member of the genus Flavivirus (Flaviviridae), is a causative agent of a severe neuroinfection. Recently, several flaviviruses have been shown to interact with host protein synthesis. In order to determine whether TBEV interacts with this host process in its natural target cells, we analysed de novo protein synthesis in a human cell line derived from cerebellar medulloblastoma (DAOY HTB-186). We observed a significant decrease in the rate of host protein synthesis, including the housekeeping genes HPRT1 and GAPDH and the known interferon-stimulated gene viperin. In addition, TBEV infection resulted in a specific decrease of RNA polymerase I transcripts, 18S and 28S rRNAs and their precursor, 45-47S pre-rRNA, but had no effect on the RNA polymerase III-transcribed 5S rRNA levels.

Molecular Factors of Cell Antiviral Immunity
 SELINGER, Martin
The proposed thesis focuses on the description of flavivirus-host interactions in case of tick-borne encephalitis virus (TBEV) and Zika virus (ZIKV). In more detail, the TBEV-induced host responses in human cells of neural origin and interferon-mediated protection were described together with the identification of a new phenomenon of TBEV-induced host transcriptional and translational shut-off. In addition, virus-derived molecules with hypothetical immunomodulatory characteristics, TuORF and ZIKV sfRNA, were analysed for their presence and possible function during the infection.
