中文摘要
先天性巨细胞病毒(CMV)感染是儿童感音神经性聋(SNHL)的主要病因。虽然CMV诱导的SNHL的重要性已被描述,但其发病机制和炎症反应的作用仍不清楚。本研究提出了一种新生小鼠模型,通过将病毒直接注射到脑室中引起深度SNHL。免疫组化染色可见螺旋神经节神经元内有感染细胞。但2周后,在感染小鼠中未检测到感染细胞。光学显微镜下未观察到小鼠耳蜗的明显炎症变化。问题仍然是为什么CMV相关的听力损失在这种小鼠模型中是进行性的。
英文摘要
Congenital cytomegalovirus(CMV) infection is the leading of sensorineural hearing loss(SNHL) in children. While the importance of CMV-induced SNHL has been described, the mechanisms surrounding its pathogenesis and the role of inflammatory responses remain unclear. This study presents a neonatal mouse model of profound SNHL caused by directly injecting the virus into cerebral ventricles. Infected cells were detected in the spiral ganglion neurons in immunostain. But after 2 weeks the infected cells were not detected in the infected mice. No significant inflammatory changes in the cochleae of the mice were observed under the light microscope analysis. The question remains why the CMV-related hearing loss is progressive in this murine model.
