在严重联合免疫缺陷小鼠模型中,水痘带状疱疹病毒(VZV)ORF61蛋白是人体皮肤移植正常复制和体内毒力所必需的。这些实验确定了一个疏水结构域,介导ORF61的自我相互作用。虽然不需要抑制宿主细胞的防御,但该结构域(250-320位残基)的破坏严重损害了VZV的生长,即时早期63和糖蛋白E基因的反式激活,以及VZV皮肤感染的体内发病机制。
The varicella-zoster virus (VZV) ORF61 protein is necessary for normal replicationin vitroand virulence in human skin xenografts in the severe combined immunodeficiency mouse modelin vivo. These experiments identify a hydrophobic domain that mediates ORF61 self-interaction. While not needed to inhibit host cell defenses, disruption of this domain (residues 250 to 320) severely impairs VZV growth, transactivation of the immediate early 63 and glycoprotein E genes, and the pathogenesis of VZV skin infectionin vivo.
