(英) As leukocytes can penetrate into deep regions of a tumor mass, leukocyte-mimetic liposomes (LM-Lipo) containing leukocyte membrane proteins are also expected to penetrate into tumors by exerting properties of those membrane proteins. The aim of the present study was to examine whether LM-Lipo, which were recently demonstrated to actively pass through inflamed endothelial layers, can penetrate into tumor spheroids, and to investigate the potential of LM-Lipo for use as an anticancer drug carrier. We prepared LM-Lipo via intermembrane protein transfer from human leukemia cells; transfer of leukocyte membrane proteins onto the liposomes was determined by Western blotting. LM-Lipo demonstrated a significantly high association with human lung cancer A549 cells compared with plain liposomes, which contributed to effective anti-proliferative action by encapsulated doxorubicin hydrochloride (DOX). Confocal microscopic images showed that LM-Lipo, but not plain liposomes, could efficiently penetrate into A549 tumor spheroids. Moreover, DOX-encapsulated LM-Lipo significantly suppressed tumor spheroid growth. Thus, leukocyte membrane proteins transferred onto LM-Lipo retained their unique function, which allowed for efficient penetration of the liposomes into tumor spheroids, similar to leukocytes. In conclusion, these results suggest that LM-Lipo could be a useful tumor-penetrating drug delivery system for cancer treatment. |
