Summary Introduction
Endocytosis is an important cellular mechanism in which various substances enter into the cell. Mammalian cells contain various types of endocytic pathways such as phagocytosis, clathrin-dependent endocytosis, and caveolin-dependent endocytosis. All pathways are involved in the generation of an endocytic vesicle. The vesicle containing substances are delivered to the lysosome for degradation.
