To date, it has been experimentally established that the diffusion of lipids in cytoplasmic
membranes is complex. There are several qualitatively different types of lipid diffusion:
slowed, confined, simple-Brownian, directed and hop diffusion. This poster presents a model
of lipid diffusion in heterogeneous native cytoplasmic membranes. It has been shown that
the appearance of various types of lipid diffusion mentioned above is associated with
structural changes in cytoplasmic membranes, the appearance or disappearance of a
stationary periodic network of protein-lipid domains associated with the cytoskeleton.
