Endothelial exocytosis of Weibel-Palade body (WPB) is one of the first lines of defence against vascular injury. However, the mechanisms that control WPB exocytosis in the final stages (including the docking, priming and fusion of granules) are poorly understood. Here we show that the focal adhesion protein zyxin is crucial in this process. Zyxin(More)
Total-internal-reflection fluorescence (TIRF) microscopy provides high optical-sectioning capability and a good signal-contrast ratio for structures near the surfaces of cells. In recent years, several improvements have been developed, such as variable-angle TIRF (VA-TIRF) and spinning TIRF (sp-TIRF), which permit quantitative image analysis and address(More)
Many receptor-mediated endocytic processes are mediated by constitutive budding of clathrin-coated pits (CCPs) at spatially randomized sites before slowly pinching off from the plasma membrane (60-100 s). In contrast, clathrin-mediated endocytosis (CME) coupled with regulated exocytosis in excitable cells occurs at peri-exocytic sites shortly after vesicle(More)
We demonstrate a robust high power 930 nm femtosecond Nd:fiber laser system with hollow-core photonic bandgap fiber (HC-PBGF) as the output delivery, which can be easily integrated into compact two-photon microscopy system for bio-imaging. The whole laser system can deliver up to 17.4 nJ, 220-fs pulses at 930 nm with repetition rate of 46 MHz. In this(More)
