Development of a blocking ELISA for evaluating neutralizing antibodies in human and canine serum based on rabies virus glycoprotein epitope I.

Rabies virus (RABV) is extremely hazardous to both humans and animals, causing up to 100 % death. Accurate and easy-to-use serological evaluation of vaccine potency following immunization is crucial for rabies control. In this study, recombinant RABV glycoprotein (rG) was designed and produced in 293FT cells.

Variation of gene expression of fatty acid acyl CoA reductase associated with wax secretion of a scale insect, Ericerus pela, and identification of its regulation factors through the accessible chromatin analyses and yeast one-hybrid.

The Chinese white wax scale insect (CWWSI), Ericerus pela, can secret an amount of wax equivalent to their body weight. Previous studies demonstrated the fatty acyl-CoA reductase (far3) plays a pivotal role in wax secretion of CWWSI. The high expression of far3 is crucial for the massive wax secretion.

EDIII-Fc induces protective immune responses against the Zika virus in mice and rhesus macaque.

Zika virus can infect the fetus through the placental barrier, causing ZIKV congenital syndrome and even miscarriage, which can cause great harm to pregnant women and infants. Currently, there is no vaccine and drug available to combat the Zika virus. In this study, we designed a fusion protein named EDIII-Fc, including the EDIII region of Zika E protein and human IgG Fc fragment, and obtained 293T cells that stably secreted EDIII-Fc protein using the lentiviral expression system.
