In this study, the authors examined the role of bovine herpesvirus type 1 (BHV-1) Us9 in the anterograde transport of the virus from trigeminal ganglia (TG) to nose and eye upon reactivation from latency. During primary infection, both BHV-1 Us9-deleted and BHV-1 Us9-rescued viruses replicated efficiently in the nasal and ocular epithelium. However, upon reactivation from latency, only the BHV-1 Us9-rescued virus could be isolated in the nasal and ocular shedding. By real-time polymerase chain reaction, comparable DNA copy numbers were detected in the TGs during latency and reactivation for both the viruses. Therefore, Us9 is essential for reactivation of the virus in the TG and anterograde axonal transport from TG to nose and eye.
在本研究中,作者检测了牛疱疹病毒1型(BHV-1)的Us9在病毒从三叉神经节(TG)潜伏激活后向鼻和眼的顺行运输中的作用。在初次感染期间,缺失BHV-1 Us9的病毒和拯救了BHV-1 Us9的病毒均能在鼻和眼上皮中高效复制。然而,在潜伏激活后,仅能在鼻和眼分泌物中分离到拯救了BHV-1 Us9的病毒。通过实时聚合酶链反应,在两种病毒的潜伏和激活期间,TG中检测到的DNA拷贝数相当。因此,Us9对于病毒在TG中的激活以及从TG到鼻和眼的轴突顺行运输至关重要。
