Receptor-Mediated Endocytosis: Cellular Uptake of Specific Molecules

Receptor-mediated endocytosis is a process by which cells selectively internalize specific molecules from the extracellular environment. It involves the binding of specific ligands to receptors on the cell surface, followed by the formation of clathrin-coated pits and subsequent internalization of the ligand-receptor complex into the cell through invagination of the plasma membrane. This process is highly regulated and allows cells to efficiently take up specific molecules, such as nutrients, hormones, and signaling molecules, from the extracellular space.
