“程序性细胞死亡”用于描述被细胞毒性 T 细胞或生长因子剥夺杀死的细胞的死亡。尽管bcl-2可以防止缺乏生长因子的细胞死亡,但它无法保护细胞免遭T细胞杀伤。尽管有 bcl-2 表达,靶细胞的 DNA 仍被降解为核小体大小的片段。因此,因子剥夺诱导的细胞凋亡的早期步骤与细胞毒性 T 细胞触发的细胞凋亡的早期步骤不同,尽管它们具有共同的最终途径,即 DNA 降解和细胞质膜完整性丧失。
'Programmed cell death' has been used to describe the death of cells killed by cytotoxic T cells or growth factor deprivation. Although bcl-2 can prevent death of cells deprived of growth factor, it failed to protect cells against T cell killing. In spite of bcl-2 expression, the DNA of targeted cells was degraded into nucleosome-sized fragments. Therefore the early steps in apoptosis induced by factor deprivation differ from those triggered by cytotoxic T cells, although they share a common final pathway featuring degradation of the DNA and loss of cytoplasmic membrane integrity.
