Abstract

Nanoscale view of cell membrane lipids Cholesterol-mediated lipid interactions, such as nanodomain formation, are considered vital in a cell, but because of the lack of suitable detection techniques, their spatiotemporal range remained highly controversial. Here, Eggeling et al. use subdiffraction-resolution STED (stimulated emission depletion) fluorescence microscopy to detect the diffusion of single lipids or glycosylphosphatidylinositol (GPI)-anchored proteins on the plasma membrane of a living cell. Tuning the probing spot area up to about 70-fold below that of a confocal microscope reveals that unlike phosphoglycerolipids, sphingolipids and GPI-anchored proteins are trapped for about 10 ms in cholesterol-mediated complexes within less than 20 nm space. Optical probing in nanosized areas is a powerful new approach to study biomolecular function.
