自噬体是在巨噬过程中形成的双膜细胞器。它们的作用是将细胞质物质运送到溶酶体中降解。自噬体以一种全新的方式形成,是大量膜重塑过程的结果,涉及许多蛋白质-脂质相互作用。虽然大多数研究都集中在参与自噬体形成的蛋白质上,但很明显,包括磷脂、鞘脂和固醇在内的脂类也起着同样重要的作用。在此,我们总结了目前关于脂质作用的知识,特别是磷脂及其在自噬体形成和融合过程中与自噬蛋白机制的相互作用。
Autophagosomes are double membrane organelles that are formed during a process referred to as macroautophagy. They serve to deliver cytoplasmic material into the lysosome for degradation. Autophagosomes are formed in a de novo manner and are the result of substantial membrane remodeling processes involving numerous protein-lipid interactions. While most studies focus on the proteins involved in autophagosome formation it is obvious that lipids including phospholipids, sphingolipids and sterols play an equally important role. Here we summarize the current knowledge about the role of lipids, especially focusing on phospholipids and their interplay with the autophagic protein machinery during autophagosome formation and fusion.
