    With the aim of developing a new vaccine candidate using a recombinant baculovirus (rBV) expressing the Junín virus (JUNV) GP1 and GP2 proteins on its surface, a pBacPAK9 vector containing the BV-GP64 signal peptide, the JUNV GP1-GP2 and the transmembrane domain of the vesicular stomatitis virus G (VSV-G) protein were synthesized. This plasmid was co-transfected with the bApGOZA bacmid into Sf9 cells. The rBV was recovered from the supernatant. Protein ex... ...点击完成人机验证后继续浏览

    为了开发一种新的疫苗候选物,使用表达Junín病毒(JUNV)GP1和GP2蛋白的重组杆状病毒(rBV)作为载体,合成了一个包含BV-GP64信号肽、JUNV GP1-GP2以及狂犬病病毒G(VSV-G)跨膜域的pBacPAK9质粒。该质粒与bApGOZA bacmid共转染到Sf9细胞中。从上清液中回收rBV,通过Western blot和免疫荧光染色及病毒测定法使用人血清以及抗GPC单克隆抗体确认蛋白表达情况。在ELISA测试中,用rBV免疫的小鼠表现出特异性抗体水平,在斑块减少试验中也显示出与对照组相比具有中和特性。用rBV免疫的地鼠并用JUNV攻击后,地鼠部分得到了保护,与Candid#1疫苗相比效果较弱。我们开发了一种rBV表面展示平台来验证潜在的JUNV疫苗候选物。
