Annotation description: | Figure 1C-F: WT neurons (black bars) showed robust DCV fusion after the first AP burst while fusion in SNAP-25 KO (red bars) neurons was strongly impaired. The blue bars represent stimulation (16×50AP@50Hz). Figure 1H: The DCV fusion probability, defined as the number of fusion events/total DCV number per cell, was strongly reduced in SNAP-25 KO neurons compared to WT. Figure 2 D-K: The significant reduction in DCV number and fusion probability is seen only at DIV4. Figure 4 A, C-D: Lentiviral expression of SNAP-25 in SNAP-25 KO neurons fully rescued DCV fusion capacity with a similar number of fusion events and a fusion probability as that in WT neurons. Figure 4E: The DCV fusion rate (number of fusion events over time) was similar between WT and SNAP-25 KO neurons expressing SNAP-25. |
