自体吞噬（细胞被产生于同一细胞的酶所消化的过程）
Among them, only apoptosis and autophagy are well known. 其中研究最为清楚的是细胞凋亡和自噬两种方式。
Autophagy also plays an important role in virus replication. 细胞自噬也在病毒复制方面扮演了重要角色。
Autophagy is a fail-safe against such a destructive mistake. 对于这种破坏而造成的错误，自噬作用称得上是保全系统。
In tumour cells with defects in apoptosis, autophagy allows prolonged survival. 在凋亡缺陷的肿瘤细胞中，自噬延长了生存期。
Cytoplasmic components may well be scavenged by selective autophagy. 细胞质的组分能通过选择性的自噬作用被摄
