Borna disease virus (BDV) is unique amongst animal RNA viruses in its molecular biology and capacity to cause persistent, noncytolytic CNS-infection in a wide variety of host species. Unlike other non-segmented negative-strand RNA animal viruses, BDV replicates in the nucleus of the host cell where splicing is employed for expression of a very compact genome. Epidemiological studies indicate a broad host range and geographical distribution, and some investigators have proposed that human infection may result in neuropsychiatric disorders. Experimental Borna disease in neonatal and adult rats provides an intriguing model for immune-mediated disturbances of brain development and function.
博尔纳病病毒(BDV)在动物RNA病毒中独具特色,其分子生物学特性以及在多种宿主物种中引发持续性、非细胞溶解性中枢神经系统感染的能力均十分独特。与其他非节段性负链RNA动物病毒不同,BDV在宿主细胞核内复制,在此过程中通过剪接来表达一个非常紧凑的基因组。流行病学研究表明其宿主范围广泛且地理分布广泛,一些研究人员提出人类感染可能会导致神经精神障碍。新生和成年大鼠的实验性博尔纳病为免疫介导的脑发育和功能障碍提供了一个有趣的模型。
