SARS患者尸检组织的病理学特征显示,局限性组织(如肺)损伤严重,其他组织(如肠和脑)无明显细胞损伤。在这里,我们检测了人(OL)和大鼠(C6)来源的神经细胞系对SARS相关冠状病毒的敏感性。两种神经细胞系均未表现出明显的细胞病变效应(CPE),但产生了感染性为102-5个/ml的病毒,与之形成鲜明对比的是,感染的Vero E6细胞产生的病毒为-gt;109个/ml,表现为裂解感染,呈典型的圆形CPE。有趣的是,肠道细胞系Caco-2的感染也没有引起明显的CPE,病毒的产量略低于Vero E6细胞培养的水平。值得注意的是,病毒的细胞受体血管紧张素转换酶2在Vero E6和Caco-2细胞上的表达水平相似,但在OL和C6细胞上的表达水平无法检测到。
Pathological characterization of autopsied tissues from patients with SARS revealed severe damage in restricted tissues, such as lung, with no apparent cell damage in other tissues, such as intestine and brain. Here, we examined the susceptibility of neural cell lines of human (OL) and rat (C6) origins to SARS-associated coronavirus. Both of the neural cell lines showed no apparent cytopathic effects (CPE) by infection but produced virus with infectivity of 102–5 per ml, in sharp contrast to the production by infected Vero E6 cells of >109 per ml that showed a lytic infection with characteristic rounding CPE. Interestingly, the infection of intestinal cell line CaCo-2 also induced no apparent CPE, with production of the virus at a slightly lower level as that of the Vero E6 cell culture. Notably, the cellular receptor for the virus, angiotensin-converting enzyme 2 was expressed at similar levels on Vero E6 and CaCo-2 cells, but at undetectable levels on OL and C6 cells.
