研究表明,严重急性呼吸综合征相关冠状病毒(SARS-CoV)3a和7a蛋白,而不是膜(M)蛋白,诱导哺乳动物细胞凋亡。然而,在使用杆状病毒/昆虫细胞表达系统表达SARS-CoV M蛋白时,我们发现表达的M蛋白引发了昆虫细胞的加速凋亡,其特征在于快速细胞死亡,细胞毒性升高,细胞皱缩,核浓缩和DNA片段化。相反,在哺乳动物细胞中表达的M蛋白不诱导细胞凋亡。这是第一份描述SARS冠状病毒M蛋白在动物细胞中诱导细胞凋亡的报告,并讨论了可能的影响。
It has been shown that severe acute respiratory syndrome‐associated coronavirus (SARS‐CoV) 3a and 7a proteins, but not membrane (M) protein, induce apoptosis in mammalian cells. Upon expression of SARS‐CoV M protein using the baculovirus/insect cell expression system, however, we found that the expressed M protein triggered accelerated apoptosis in insect cells, as characterized by rapid cell death, elevated cytotoxicity, cell shrinkage, nuclear condensation and DNA fragmentation. Conversely, the M protein expressed in mammalian cells did not induce apoptosis. This is the first report describing the induction of apoptosis by SARS‐CoV M protein in animal cells and possible implications are discussed.
