Lastly, genistein treatment also inhibited transduction of cells with pseudotyped retrovirus particles expressing envelope proteins of the Old World arenavirus Lassa virus.
Antibodies against conformational envelope were detected by an immunoflourescent staining assay for Vero cells expressing envelope.
The experimental strategy described in this study should be applicable for developing agonistic aptamers targeting a broad range of cell surface-expressed envelope glycoproteins of other viruses.
However, the background fluorescence signal associated with the interaction of the CD4/CXCR4-proteoliposomes with control cells not expressing envelope glycoproteins was significantly higher than that of CD4-proteoliposomes.
Firstly, using immunofluorescence and FACS analysis of cells expressing envelope HCV glycoproteins, Fab e20 was able to recognize all HCV genotypes.
Here we describe the induction of HIV-1-specific antibody and T cell responses in subjects primed by DNA immunization with plasmids expressing envelope (env) genes from clades A, B, and C, and gag, pol, and nef genes from clade B [19], [20], and boosted with recombinant adenovirus serotype 5 (rAd5) vectors expressing matching genes but lacking nef [18].
The Phase III trial in Thailand evaluated a recombinant canarypox vector expressing Envelope, Gag, and parts of Pol and Nef proteins from HIV-1 subtype B/E in combination with a recombinant HIV-1 B/E gp120 formulated in alum [1].
Of the antibodies produced from vaccine recipients, only one of 21 mAbs were able to mediate ADCC activity against four chronically infected cell lines expressing envelope from distinct HIV clades (Bonsignori et al., 2012).
Briefly, Huh7 cells [46] were transfected with a plasmid to initiate HDV genome replication and a plasmid to express the envelope proteins of HBV (genotype A, subtype adw2).
