| Outline of Final Research Achievements |
We used total internal reflection fluorescence microscopy at the live isolated calyx of Held terminal and visualized fusions and pre-fusion activities of single synaptic vesicles just beneath the plasma membrane.
We also measured vesicle membrane and protein retrieval at the same time and in the same cell at the calyx of Held from rats and mice, and found that there may be two distinct modes of membrane and vesicle protein retrieval depending on the activity strength. We also found an important signaling pathway to couple vesicle membrane and vesicle protein uptakes.
