receptor-mediated endocytosis

the process carried out in CLATHRIN coated pits, whereby specific macromolecules are transported into eukaryotic cells subsequent to binding to specific cell-surface receptors.

The significant difference in cellular uptake of [[sup.131]I]GNR-PEG-cRGD by B16F10 and MCF-7 cells confirmed receptor-specific internalization of the probes, suggesting that the probes were taken up by tumor cells via receptor-mediated endocytosis. However, [[sup.131]I]GNR-PEG-cRGD accumulation in MCF-7 cells and blocked B16F10 cells was up to about 20% because of passive uptake, which may be explained by the following three reasons.
When a transferrin protein loaded with iron encounters a transferrin receptor on the surface of a cell, it binds to it and, as a consequence, is transported into the cell in a vesicle by receptor-mediated endocytosis. The pH of the vesicle is reduced by hydrogen ion pumps ([H.sup.+]-ATPases) to about 5.5, causing transferrin to release its iron ions.
Receptor-mediated endocytosis is a prerequisite for fusion and uncoating of all known Flaviviridae family members.
The folate-conjugated nanoparticles were found to be distributed within the cytoplasm, suggesting cellular internalization through receptor-mediated endocytosis, instead of adhesion to the cell surface.
