Mechanics of Plasma Membrane Vesicles in Cells
Abstract The mechanical characteristics of biological membranes are of fundamental importance in cellular biology. Many cellular processes, such as endocytosis, exocytosis and cell fusion, are strongly involved with large mechanical deformations of the membrane accompanied by changes in curvature [1]. One of the remarkable features in this respect are local membrane regions with high curvature, such as the clathrin-coated pits, vesicles, chained vesicles and channels which facilitate the cell to transport specific macromolecules. In this study, mechanics of plasma membrane vesicles in cells have theoretically been investigated based on minimization of bending and in-plane shear strain energy of the membrane. Effects of outer surrounding cytoplasmic flat membrane upon mechanically stable shapes of the vesicles were revealed as well as the effects of the in-plane shear elasticity.
