Project description:There are very few studies exploring the genetic diversity of tick-borne encephalitis complex viruses. Most of the viruses have been sequenced using capillary electrophoresis, however, very few viruses have been analyzed using deep sequencing to look at the genotypes in each virus population. In this study, different viruses and strains belonging to the tick-borne encephalitis complex were sequenced and genetic diversity was analyzed. Shannon entropy and single nucleotide variants were used to compare the viruses. Then genetic diversity was compared to the phylogenetic relationship of the viruses.

Sequential MAVS- and MyD88/TRIF-signaling triggers anti-viral responses of tick-borne encephalitis virus-infected murine astrocytes

Project description:Upon tick borne encephalitis virus exposure of brain-resident cells, astrocytes are important IFN-β producers that followed a biphasic response, which initially depends on MAVS- and later on MyD88/TRIF-signaling

Genotype-Driven Sensitivity in Mice to Tick-Borne Encephalitis Virus Correlates with Differential Host Responses in Peripheral Macrophages and Brain

Project description:Tick-borne encephalitis (TBE) is the most common tick-borne viral infection in Eurasia, with outcomes ranging from asymptomatic to fatal encephalitis. While the reasons for this variability are unclear, host genetics likely plays a role. Our previous research showed that BALB/c mice have intermediate susceptibility to TBE virus (TBEV), STS mice are highly resistant, and the recombinant congenic strain CcS-11, which has 12.5% of the STS genome on the BALB/c background, is more susceptible than the BALB/c. In this study, we used these three mouse strains to investigate the host response to TBEV infection in both peripheral macrophages, one of the initial target cell populations, and in the brain, the terminal target organ for the virus.

Plasma proteomic profile of patients with tick-borne encephalitis and co-infections

Project description:Despite the increasing number of patients suffering from tick-borne diseases, including tick-borne encephalitis (TBE) and Lyme disease, the mechanisms of development of these diseases and their effects on human body are still unknown. Moreover, the increasing number of cases of co-infections of these diseases additionally hampers the correct diagnosis and the application of effective therapy. Therefore, the aim of this study was to evaluate the changes in proteomic profile of human plasma induced by the development of TBE and to compare it with changes in TBE patients co-infected with other tick-borne pathogens. The results obtained by proteomic analysis using nanoLC-QExactive/MS showed that the most highly elevated groups of proteins in the plasma of TBE patients with co-infection were involved in the pro-inflammatory response and protein degradation, while the antioxidant proteins and factors responsible for protein biosynthesis were mainly down regulated. The main proteins, which expression differentiated patients with TBE from co-infected patients, such as AP-1, fumarylacetoacetase, serpin, annexin, or carbonic anhydrase 2, are involved in TBE virulence or antibacterial responses. These results were accompanied by the enhanced GSH- and 4-HNE-protein adducts formation, observed in TBE and co-infected patients on higher level than in the case of only TBE patients. In conclusion, the differences in the proteomic profiles between patients with TBE and co-infected indicate that the mechanisms of development of these diseases are diverse and, consequently, require different treatment, what is particularly important for further research, including the development of novel diagnostics tools.
