摘要
自噬将细胞质部分封存到自噬体中。选择性货物通过杯状隔离膜(IMs)的伸长被吞噬,而非选择性IMs的形态发生仍然难以捉摸。根据最近的观察结果,我们提出了一种新的自噬体形态发生模型,其中对 IM 边缘的主动调控为自噬的生理作用服务。
The physiological relevance of autophagosome morphogenesis
Autophagy sequesters cytoplasmic portions into autophagosomes. While selective cargo is engulfed by elongation of cup-shaped isolation membranes (IMs), the morphogenesis of non-selective IMs remains elusive. Based on recent observations, we propose a novel model for autophagosome morphogenesis wherein active regulation of the IM rim serves the physiological roles of autophagy.
