英文摘要Cell-penetrating peptides (CPPs) can aid in intracellular and in vivo drug delivery. However, the mechanisms of CPP-mediated penetration remain unclear, limiting the development and further application of CPPs. Flow cytometry and laser confocal fluorescence microscopy were performed to detect the effects of different endocytosis inhibitors on the internalization of CC12 and penetratin in ARPE-19 cells. The co-localization of CPPs with the lysosome and macropinosome was detected via an endocytosis tracing experiment. The flow cytometry results showed that chlorpromazine, wortmannin, cytochalasin D, and the ATP inhibitor oligomycin had dose-dependent endocytosis-inhibitory effects on CC12. The laser confocal fluorescence results showed that oligomycin had the most significant inhibitory effect on CC12 uptake; CC12 was co-located with the lysosome, but not with the macropinosome. For penetratin, cytochalasin D and oligomycin had obvious inhibitory effects. The laser confocal fluorescence results indicated that oligomycin had the most significant inhibitory effect on penetratin uptake; the co-localization of penetratin with the lysosome was higher than that with the macropinosome. Cation-independent CC12 and cationic penetratin may be internalized into cells primarily through caveolae and clathrin-mediated endocytosis, and they are typically dependent on ATP. The transport of penetratin could be partly achieved through the direct transmembrane pathway, as the positive charge of penetratin interacts with the negative charge of the cell membrane, and partly through the endocytic pathway.
