Course content

Biological membranes are the nanoscale boundaries that separate the cytoplasm of the cell from the extracellular environment and define intracellular compartments and organelles. While initially recognized mostly as static, it is now established that membranes change shape and properties in striking ways thus controlling multiple fundamental processes of life such as cell signaling and sensory pathways. Their overall shape and characteristics is tightly regulated by a continuous interplay between the lipid constituents and membrane-associated proteins. On the other hand multiple’s protein function as well as trafficking and sorting are regulated by membrane characteristics and shape. As a result a multitude of essential cellular functions including endocytosis and signalling are controlled by the complex interplay between membrane properties and membrane associated proteins properties on the nanoscale.

The aim of this class is to provide essential understanding of the membrane-related nanoscale processes that control key elements of cellular life. Initially we will discuss the effect of membrane characteristics such as composition shape and nanodomain formation, on the dynamics and function of enzymes associated or activated by membranes. Some emphasis will be put on experiments of single molecule activity. We will continue with the mechanisms of membrane-mediated protein trafficking and sorting in cellular compartments and its relation to signaling pathways. Subsequently we will focus on nanoscale lipid assemblies (lipid vesicles) and will discuss the proteins and the mechanisms involved in membrane remodeling during cellular functions such as endocytosis, SNARE mediated fusion and vesicle trafficking. By the end of the class students will be well acquainted with a mechanistic knowledge of multiple membrane-related cellular functions and the latest nanoscale techniques used to characterize them.

Learning outcome
