Membrane Skeleton Detachment in Spherical and Cylindrical Microexovesicles

摘要

We observed that amphiphile-induced microexovesicles may be spherical or cylin- drical, depending on the species of the added amphiphile. The spherical microex- ovesicle corresponds to an extreme local difference between the two monolayer areas of the membrane segment with a fixed area, while the cylindrical microex- ovesicle corresponds to an extreme local area difference if the area of the budding segment is increased due to lateral influx of anisotropic membrane constituents.
