38ab InVivoMAb抗登革热病毒4型E卵白DIII

DV4-E88单克隆抗体与登革热病毒血清型4(DENV-4)E卵白上的DIII结构域响应。这种血清型特异性抗体不会与登革病毒1型、登革病毒2型或登革病毒3型(即登革病毒的其他血清型)发生交叉响应。登革病毒是一种由埃及伊蚊和白纹伊蚊传播的黄病毒38ab,每年在热带和亚热带地区形成向上1亿东谈主感染。轻度登革热的特征是发热、头痛和肌痛,而重度登革热可导致出血和毛细血管渗漏空洞征,即登革热出血热(DHF)/登革热休克空洞征(DSS)。从结构上讲,DENV是一种单链正极性RNA病毒,其包膜(E)卵白有三个结构域。DV4-E88单克隆抗体(构象地)探究DENV-4(E二聚体上的四表位)上结构域III(DIII)的侧脊(LR)。该抗体不识别酵母名义抒发或永诀的DENV-4 E卵白DIII。DIII-LR区含有宿主细胞名义受体识别位点,参与病毒中庸抗体的指点。在体外商议中,DV4-E88单克隆抗体中庸了1036株、TVP-376株和TVP-986株DENV-4基因型II毒株。在触及AG129小鼠的实践中,在病毒感染前单次体内打针DV4-E88单克隆抗体(100-500µg/小鼠)对DENV-4毒株H-241和TVP-376提供了为止到权臣的保护。
