PEGylated nanoparticles and macromolecules are increasingly used in cancer imaging and anticancer treatment. The role of receptor-mediated endocytosis in the efficacy of these agents, however, has not been clearly defined. Here, we developed a matched pair of endocytic and nonendocytic receptors to directly and unambiguously assess this issue. The ligand-binding domains of the low-density lipoprotein receptor (LDLR) or a truncated LDLR lacking the NPXY endocytosis motif (DeltaLDLR) were… CONTINUE READING
