More specifically, we identified an epitope on Zika virus (ZIKV) envelope protein domain III (EDIII) that is buried in the full-length envelope protein but becomes exposed in recombinant EDIII.
Furthermore, TRPV4 mediates Ca<sup>2+</sup> influx and nuclear accumulation of DDX3X in cells exposed to the Zika virus or the purified viral envelope protein.
Recent studies have identified potential B-cell epitopes (amino acids 241-259, 294-315, 317-327, 346-361, 377-388 and 421-437) on the envelope protein of ZIKV, which could be explored to develop peptide vaccines against ZIKV infection.
Study of the mechanism of protonated histidine-induced conformational changes in the Zika virus dimeric envelope protein using accelerated molecular dynamic simulations.
We also demonstrated that the Zika virus (ZIKV) VLP production level was enhanced by introducing the same F108A mutation into the ZIKV envelope protein.
Using 60 sequences of the Zika virus envelope protein available in the GenBank database, our analysis with numerical characterization techniques and several web based bioinformatics servers identified four peptide stretches on the Zika virus envelope protein that are well conserved and surface exposed and are predicted to have reasonable epitope binding efficiency.
In this study we established a competitive amplified luminescent proximity homogeneous assay (ALPHAscreen) to identify small molecule inhibitors targeting the envelope protein of Zika virus (Zika E).
Results obtained from this study indicate the potential of the Asian-lineage Zika Env-CD4 and Env proteins in ELISA assays to monitor humoral immune responses in upcoming clinical trials as well as a sero-diagnostic tool in ZIKV infection.
As a proof of concept, we utilized our plasmonic metasurface to detect Zika-virus (ZIKV) envelope protein (with diameter of 40 nm) using a specific ZIKV antibody.
The envelope protein of Zika virus (ZIKV) exists as a dimer on the mature viral surface and is an attractive antiviral target because it mediates viral entry.
Using 153 patient specimens with known ZIKV and/or dengue virus (DENV; a closely related flavivirus) infections, we showed that (i) ZIKV envelope-based MIA is equivalent or more sensitive than IgM-capture ELISA in diagnosing ZIKV infection, (ii) antibody responses to NS1 and NS5 proteins are more ZIKV-specific than antibody response to envelope protein, (iii) inclusion of NS1 and NS5 in the MIA improves the diagnostic accuracy when compared with the MIA that uses envelope protein alone.
Thus, the present study demonstrates that the lateral ridge region of the envelope protein is likely an immunodominant, neutralizing epitope.<b>IMPORTANCE</b> Zika virus (ZIKV) is a global health threat causing severe disease in humans, including microcephaly in newborns and Guillain-Barré syndrome in adults.
