Abstract

The intestinal barrier has always been the rate-limiting step in the oral administration process. To overcome the intestinal barrier, researchers have widely adopted nanocarriers, especially active-targeting nanocarriers strategies. However, most of these strategies focus on the ligand decoration of nanocarriers targeting specific receptors, so their applications are confined to specific receptors or specific cell types. In this study, we tried to investigate more common strategies in the field of transmembrane transport enhancement. Trans-Golgi network (TGN) is the sorting center of biosynthetic route which could achieve polarized localization of proteins in polarized epithelial cells, and the basolateral plasma membrane is where all transcytotic cargos have to pass through. Thus, it is expected that guiding nanocarriers to TGN or basolateral plasma membrane may improve the transcytosis. Hence, we choose sorting signal peptide to modify micelles to guide micelles to TGN (named as BAC decorated micelles, BAC-M) or to basolateral plasma membrane (named as STX decorated micelles, STX-M). By incorporating coumarin-6 (C6) or Cy5-PEG-PCL in the micelles to indicate the behavior of micelles, the effects of these two strategies on the transcytosis were investigated. To our surprise, BAC-M and STX-M behaved quite differently when crossing biological barriers. BAC-M showed significant superiority in colocalization with TGN, transmembrane transport and even in vivo absorption, while STX-M had no significant difference from blank micelles. Further investigation revealed that the strategy of directly guiding nanocarriers to the basolateral plasma membrane (STX-M) only caused the stack of vesicles near the basolateral plasma membrane. So, we concluded that guiding nanocarriers to TGN which related to secretion may contribute to the transmembrane transport. This common strategy based on the physiological function of TGN in polarized epithelial cells will have broad application prospects in overcoming biological barrier.
