Atomic-level functional model of dengue virus Envelope protein infectivity.

A number of structures have been solved for the Envelope (E) protein from dengue virus and closely related flaviviruses, providing detailed pictures of the conformational states of the protein at different stages of infectivity. However, the key functional residues responsible for mediating the dynamic changes between these structures remain largely unknown. Using a comprehensive library of fun...

Dengue virus type-3 envelope protein domain III; expression and immunogenicity

Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...

Antibodies against the Envelope Glycoprotein Promote Infectivity of Immature Dengue Virus Serotype 2

Cross-reactive dengue virus (DENV) antibodies directed against the envelope (E) and precursor membrane (prM) proteins are believed to contribute to the development of severe dengue disease by facilitating antibody-dependent enhancement of infection. We and others recently demonstrated that anti-prM antibodies render essentially non-infectious immature DENV infectious in Fcγ-receptor-expressing ...

The middle hepatitis B virus envelope protein is not necessary for infectivity of hepatitis delta virus.

The hepatitis delta virus (HDV) envelope contains the large (L), middle (M), and small (S) surface proteins encoded by coinfecting hepatitis B virus. Although HDV-like particles can be assembled with only the S protein in the envelope, the L protein is essential for infectivity in vitro (C. Sureau, B. Guerra, and R. Lanford, J. Virol. 67:366-372, 1993). Here, we demonstrate that the M protein, ...

Characterization of a dengue type-specific epitope on dengue 3 virus envelope protein domain III

Dengue virus (DENV) is a mosquito-borne disease caused by four genetically and serologically related viruses termed DENV-1, -2, -3 and -4. The DENV envelope (E) protein ectodomain can be divided into three structural domains designated ED1, ED2 and ED3. The ED3 domain contains DENV type-specific and DENV complex-reactive antigenic sites. To date, nearly all antigenic studies on the E protein ha...
