在突触囊泡融合后,超快内吞作用可在50-100 ms内恢复单个大内吞囊泡。然而,大内吞囊泡的命运尚不清楚。在这里,我们证明了这些囊泡在刺激后大约一秒转变为突触内体。内小体在3秒后分解成包被囊泡,在刺激后5-6秒内变成小直径的突触囊泡。我们使用RNAi破坏了网格蛋白的功能,发现网格蛋白不是超快内吞作用所必需的,而是内核体产生突触囊泡所必需的。当肌动蛋白聚合被破坏时,或者当神经元在室温而不是生理温度下受到刺激时,超快内吞作用就会失败。在没有超快内吞作用的情况下,突触囊泡通过网格蛋白介导的内吞作用直接从质膜中回收。这些结果在很大程度上解释了关于网格蛋白在突触囊泡内吞作用的已发表实验之间的差异。
Ultrafast endocytosis can retrieve a single large endocytic vesicle as fast as 50-100 ms after synaptic vesicle fusion. However, the fate of the large endocytic vesicles is not known. Here we demonstrate that these vesicles transition to a synaptic endosome about one second after stimulation. The endosome is resolved into coated vesicles after 3 seconds, which in turn become small-diameter synaptic vesicles 5-6 seconds after stimulation. We disrupted clathrin function using RNAi and found that clathrin is not required for ultrafast endocytosis but is required to generate synaptic vesicles from the endosome. Ultrafast endocytosis fails when actin polymerization is disrupted, or when neurons are stimulated at room temperature instead of physiological temperature. In the absence of ultrafast endocytosis, synaptic vesicles are retrieved directly from the plasma membrane by clathrin-mediated endocytosis. These results explain in large part discrepancies among published experiments concerning the role of clathrin in synaptic vesicle endocytosis.
