埃博拉病毒感染的幸存者可能会出现亚临床感染,但动物模型是否重现这种并发症尚不清楚。利用组织学结合免疫组织化学和原位杂交对豚鼠毒力确认研究进行回顾性审查,我们首次证明埃博拉病毒感染肝卵圆细胞、房室瓣和腱索的心内膜和间质、外周神经节的卫星细胞、外周神经和神经节的神经成纤维细胞和雪旺细胞、子宫平滑肌细胞子宫肌层和阴道壁、腮腺唾液腺腺泡、甲状腺滤泡细胞、肾上腺髓质细胞、胰岛细胞、子宫内膜腺体和表面上皮、以及阴道上皮、阴茎和包皮。这些发现表明,埃博拉病毒病的标准动物模型并不像以前想象的那样得到很好的描述,并且可以作为未来识别病毒持久性潜在位点的垫脚石。
Survivors of Ebola virus infection may become subclinically infected, but whether animal models recapitulate this complication is unclear. Using histology in combination with immunohistochemistry and in situ hybridization in a retrospective review of a guinea pig confirmation-of-virulence study, we demonstrate for the first time Ebola virus infection in hepatic oval cells, the endocardium and stroma of the atrioventricular valves and chordae tendinae, satellite cells of peripheral ganglia, neurofibroblasts and Schwann cells of peripheral nerves and ganglia, smooth muscle cells of the uterine myometrium and vaginal wall, acini of the parotid salivary glands, thyroid follicular cells, adrenal medullary cells, pancreatic islet cells, endometrial glandular and surface epithelium, and the epithelium of the vagina, penis and, prepuce. These findings indicate that standard animal models for Ebola virus disease are not as well-described as previously thought and may serve as a stepping stone for future identification of potential sites of virus persistence.
