HSV 是一种嗜神经病毒,通过快速轴突运输在神经元突内传播。在神经元感染期间,HSV 从感觉神经末端逆行至神经元细胞体,并在那里复制或进入潜伏期。在复制过程中,HSV 从细胞体顺行传播到神经末端。尸检研究发现,三叉神经节和大脑中存在高频率的 HSV DNA。将 HSV 与阿尔茨海默病 (AD) 相关的研究一直存在争议。在这里,我们回顾了支持这种联系的临床证据。此外,作者描述了实验数据,显示新生 HSV 颗粒与 AD 中涉及的宿主运输机制之间的物理相互作用。作者的结论是,尽管针对 AD 的潜在抗 HSV 治疗的相对简便性和无毒性需要进一步研究,但这种关系的复杂性尚未得到充分探讨。
HSV, a neurotropic virus, travels within neuronal processes by fast axonal transport. During neuronal infection HSV travels retrograde from the sensory nerve terminus to the neuronal cell body, where it replicates or enters latency. During replication HSV travels anterograde from the cell body to the nerve terminus. Postmortem studies find a high frequency of HSV DNA in the trigeminal ganglia as well as the brain. Studies correlating HSV with Alzheimer’s disease (AD) have been controversial. Here we review clinical evidence supporting such a link. Furthermore, the author describes experimental data showing physical interactions between nascent HSV particles and host transport machinery implicated in AD. The author concludes that the complexity of this relationship has been insufficiently explored, although the relative ease and nontoxicity of a potential anti-HSV treatment for AD demands further study.
