Caveolin mediated endocytosis is a specific type of endocytosis that involves small invaginations of the cell membrane known as caveolae. These invaginations are enriched with a protein called caveolin, which plays a crucial role in the formation and function of caveolae. This pathway is distinct from other endocytic pathways, such as clathrin-mediated endocytosis, and is involved in the internalization of various molecules including lipids, proteins, and even some nanoparticles.
