Omschrijving Various microscopy approaches used in current molecular cell biology research will be discussed. A thorough understanding of molecular cell biology research will be obtained, focusing on mitochondria and the secretory pathway. Examples of molecular cell biology research will be discussed from a molecular to cellular level using in vitro and in vivo approaches in yeast and mammalian model systems.

Microscopy:
The students will be introduced to modern microscopy techniques used in the molecular life sciences (from the protein to cellular level). Topics include electron and fluorescence microscopy of cells/tissues, the use of fluorescent dyes and proteins, special fluorescence approaches such as FRAP (fluorescence recovery after photobleaching), FCS (fluorescence correlation spectroscopy) and FRET (Förster resonance energy transfer), superresolution microscopy, atomic force microscopy and optical tweezers.

Mitochondria:
An overview will be provided of the molecular mechanisms involved in mitochondrial biogenesis and dynamics (more specifically: protein translocation, fission (Dynamin related proteins) and fusion, inheritance and transport, contact sites). The biochemical, genetic and microscopy approaches used to study mitochondria will be discussed.

Protein secretion:
Intracellular membrane trafficking will be discussed, including ER-Golgi transport, exocytosis, endocytosis and lysosomal trafficking. The students will be introduced to the key mechanisms of intracellular cargo sorting, the formation of trafficking vesicles, the docking and fusion to target organelles and the molecular determinants of organellar identity.

ESCRT System and extracellular vesicles:
Many cellular processes such as endosomal vesicle budding, virus budding, and cytokinesis require extensive membrane remodeling by the endosomal sorting complex required for transport (ESCRT), of which a mechanistic view will be presented in this course. In addition an overview on extracellular vesicles, which are for instance involved in cell-to-cell communication and disease, will be discussed from a structure/function point of view.
