我们之前已经证明,Theiler病毒,一种嗜神经的非包膜小核糖核酸病毒,可以从被感染神经元的轴突进入周围的髓鞘。当这种传输被中断时,就像在携带髓磷脂基本蛋白基因突变的颤抖小鼠中一样,病毒无法在中枢神经系统中持续存在。在目前的工作中,我们使用了Wlds突变小鼠,一种轴突变性明显减慢的菌株,以表明轴突到髓磷脂的运输发生在没有轴突变性的情况下。我们的结果表明,存在一种轴突细胞质转移到髓鞘的机制,Theiler病毒可能利用这种机制来确保其持久性。
We showed previously that Theiler's virus, a neurotropic non-enveloped picornavirus of mouse, traffics from the axon of infected neurons into the surrounding myelin. When this traffic is interrupted, as in the shiverer mouse which bears a mutation in the myelin basic protein gene, the virus is unable to persist in the central nervous system. In the present work, we used the Wlds mutant mouse, a strain in which axonal degeneration is considerably slowed down, to show that axon to myelin traffic takes place in the absence of axon degeneration. Our results suggest the existence of a mechanism of transfer of axonal cytoplasm into the myelin which Theiler's virus might exploit to ensure its persistence.
