The disease dengue (DEN) is caused by four serologically related viruses termed DEN1, DEN2, DEN3 and DEN4. The structure of the ectodomain of the envelope protein has been determined previously for DEN2 and DEN3 viruses. Using NMR spectroscopic methods, we solved the solution structure of domain III (ED3), the receptor-binding domain, of the envelope protein of DEN4 virus, human strain 703-4. The...
Neutralization of flaviviruses by antibody is primarily mediated via epitopes in the viral envelope (E) protein. Comparative studies using neutralizing monoclonal antibodies revealed differential expression of epitopes within the E protein domain III of ten naturally occurring West Nile virus strains representing major subtypes of genetic lineages 1 and 2. Residues that defined these subtype-specific...
Omsk hemorrhagic fever virus (OHF) is a tick-borne flavivirus endemic to Western Siberia. This virus is the only known tick-borne flavivirus to cause hemorrhagic disease in humans in the absence of encephalitis. OHF virus circulates within a small, defined niche in which other tick-borne complex flaviviruses are also present. The objectives of this study were to genetically classify OHF virus based...
