A striking feature of endocytosis is the large amount of surface membrane that is brought into the cells through the formation of endocytic vesicles. Little is known about the fate of this membrane material. It is implausible that it would be destroyed in lysosomes, as the rate of turnover of the constituents of plasma membrane is much too low with respect to the rate of endocytosis in all cells studied so far. Conversely, plasma membrane fragments, internalized by endocytosis cannot merely be incorporated in lysosomes, as these organelles have been shown to maintain their size, despite continuous and active endocytosis. We present evidence that plasma membrane antigens, detected by means of specific antibodies, are internalized during endocytosis and reach lysosomes. They are thereafter returned back to cell surface. These results indicate the existence of a shuttle of membrane elements between the cell surface and lysosomes.
