自噬 (Autophagy)


自噬 Autophagy

自噬涉及细胞内成分被运输到溶酶体进行降解和循环的复合分子通路,对于维持细胞和生物体内稳态发挥着十分关键的作用。然而,自噬失调也会导致非凋亡的程序性细胞死亡(图1)。

Autophagy refers to composite molecular pathways in which intracellular components are conveyed to the lysosomal compartment for degradation and recycling playing a critical role in the preservation of cellular and organismal homeostasis. However, its deregulation would result in non-apoptotic programmed cell death (Fig.1).
