Von Willebrand Factor (VWF) plays a pivotal role in blood coagulation. VWF is secreted from endothelial cell Weibel-Palade bodies (WPBs), which is crucial for the response to vascular trauma. Dysfunctional WPB biogenesis and exocytosis are characteristic of bleeding disorders such as Von Willebrand disease. In this project, we aim to identify the organelle trafficking routes responsible for WPB formation and secretion.
).
Two PhD positions are available, one at each institute.
The Erasmus MC candidate will conduct biochemical assays of WPB cargo secretion and optical assays of WPB exocytosis to determine changes in secretory competence and fusion mode due to altered SNARE sorting. Techniques include high content microscopy, proteomics, total internal reflection fluorescence (TIRF) microscopy, shRNA library screenings, and electron microscopy.
The UG candidate will utilize newly developed microscopy methods, including Förster resonance energy transfer-fluorescence lifetime imaging (FRET-FLIM), to map SNARE protein trafficking to WPBs. Techniques include FRET-FLIM microscopy, mammalian cell culturing, CRISPR, and molecular cloning.
The PhD candidates are expected to also spend research time at the other institute.
