Abstract

The eradication of infectious virus from the central nervous system (CNS) following infection with the neurotropic JHM strain of mouse hepatitis virus (JHMV) is thought to be immune-mediated. Furthermore, a significant decrease of infectious virus coincides with the appearance of prominent inflammatory infiltrates in the brain and spinal cord. In the present study, mononuclear cells infiltrating the brain during JHMV infection were isolated and characterized. While all subsets of immune cells were present, there appeared to be a temporal relationship between the peak incidence of CD8+ T cells (40% of total isolated cells) and reduction of virus at day 7 post-infection. Cells with the natural killer (NK) phenotype (at least 30%) were also present throughout infection. These data suggest that CD8+ T cells and NK cells are prominent among cells which infiltrate the brain during JHM virus infection and may have important roles in reduction of virus within the CNS.

摘要

感染嗜神经小鼠肝炎病毒(JHMV)的JHM株后,从中枢神经系统(CNS)清除传染性病毒被认为是免疫介导的。此外,传染性病毒的显著减少与脑和脊髓中明显的炎性浸润的出现同时发生。在本研究中,对JHMV感染期间浸润大脑的单核细胞进行了分离和鉴定。虽然存在所有免疫细胞亚群,但在感染后第7天,CD8 + T细胞的峰值发生率(占分离细胞总数的40%)与病毒减少之间似乎存在时间关系。具有自然杀伤(NK)表型的细胞(至少30%)在整个感染过程中也都存在。这些数据表明,CD8 + T细胞和NK细胞在JHM病毒感染期间浸润大脑的细胞中占突出地位,并且可能在中枢神经系统内病毒的减少中发挥重要作用。
