因此,autolysosome中LC3含量很低。 autophagosome与lysosome融合时,lysosome会引入组织蛋白酶,一些酸性水解酶和vATPase。vATPase通过水解ATP的能量,向腔内泵入氢离子使得autolysosome酸化,激活酸性水解酶。 2. 微自噬Microautophagy 3. 分子伴侣介导的自噬chaperone-mediated autophagy,CMA...
自噬(Autophagy) 自噬(Autophagy)是细胞内的一种重要降解和再生过程,涉及将细胞自身的部分蛋白质和细胞器包裹在双层膜结构中,形成自噬体(Autophagosome),然后运输到溶酶体(Lysosome)进行降解。这一过程对于细胞的存活、发育、应激响应以及维持细胞内稳态具有至关重要的作用。 自噬的过程大致可以分为以下几个阶段: 起始(I...
lysosome‐related disordersLysosomes degrade biological components acquired by endocytosis, the major cellular pathway for internalization of extracellular material, and macroautophagy. This chapter presents an overview of these two major degradative intracellular pathways, and highlights the emerging cross talks...
Autophagy is a major intracellular degradation system that derives its degradative abilities from the lysosome. The most well-studied form of autophagy is macroautophagy, which delivers cytoplasmic material to lysosomes via the double-membraned autophago
2022年9月18日,浙江大学与良渚实验室双聘教授和美国密歇根大学生物系客座教授徐浩新团队在Autophagy杂志在线发表题为“The Acid Gate in the Lysosome”的研究论文,该研究发现 TMEM175 基因编码溶酶体“H+ 泄漏”电流所需的质子激活质子选择性通道 (LyPAP),当溶酶体过度酸化时,LyPAP 的活性最为活跃,缺乏 TMEM175...
自噬是一种保守的分解代谢途径,介导错误折叠的蛋白质、细胞毒性聚集体和受损的细胞器在溶酶体中降解,维持细胞稳态。正常的溶酶体降解能力在自噬过程中起着关键作用。大量研究表明,溶酶体膜透化/损伤(Lysosome membrane permeabilization, LMP)...

autophagy occurs when the cell consumes part of itself). The product of the endosome-autophagosome fusion is called an amphisome. The completed autophagosome or amphisome fuses with a lysosome, which supplies acid hydrolases. The enzymes in the resulting compartment, an autolysosome, break down the ...
The meaning of AUTOPHAGY is the biological process that involves the enzymatic breakdown of a cell's cytoplasm or cytoplasmic components (such as damaged or unneeded organelles or proteins) within the lysosomes of the same cell. How to use autophagy in a
