Lactoferrin-mediated macrophage targeting delivery and patchouli alcohol-based therapeutic strategy for inflammatory bowel diseases.

ABSTRACT: Inflammatory bowel diseases (IBD) are the incurable chronic recurrent gastrointestinal disorders and currently lack in safe and effective drugs. In this study, patchouli alcohol, a main active compound of traditional Chinese herb patchouli, was developed into biomimetic liposomes for macrophage-targeting delivery for IBD treatment. The developed lactoferrin-modified liposomes (LF-lipo) can specifically bind to LRP-1 expressed on the activated colonic macrophages and achieve cell-targeting anti-inflammatory therapy. LF-lipo reduced the levels of inflammatory cytokines and ROS and suppressed the MAPK/NF-κB pathway. LF-lipo also suppressed the formation of NLRP3 inflammasome and the consequent IL-1β activation. LF-lipo showed improved therapeutic efficacy in a DSS-induced coliti
