MicroRNA-based control of tick-borne flavivirus neuropathogenesis: Challenges and perspectives.

ABSTRACT: In recent years, microRNA-targeting has become an effective strategy for selective control of tissue-tropism and pathogenicity of both DNA and RNA viruses. Previously, we reported the successful application of this strategy to control the neurovirulent phenotype of a model chimeric tick-borne encephalitis/dengue type 4 virus (TBEV/DEN4), containing the structural protein genes of a highly virulent TBEV in the genetic backbone of non-neuroinvasive DEN4 virus. In the present study, we investigated the suitability of this approach for the attenuation of the more neurovirulent chimeric virus (TBEV/LGTV), which is based on the genetic backbone of the naturally attenuated member of the TBEV serocomplex, a Langat virus (LGTV). Unlike the TBEV/DEN4, the TBEV/LGTV virus retained the ability of its
