Zusammenfassung:Abstract Objectives Orientation to specific cells is an important topic in active targeting strategy for nanoparticle-based drug delivery systems. While these administered nanoparticles will be sequestrated within the liver, their cellular distribution behaviors in the liver are not clear. The aim of this study was to fabricate glycyrrhizic acid (GL) modified BSA nanoparticles and evaluate their hepatic cellular distribution. Methods GL-modified BSA (GL-BSA) was tailored according to the periodate oxidation method, then GL-BSA nanoparticles loaded with paclitaxel (PTX@GL-BSA NPs) were prepared through self-assembly approach. In vitro cellular uptake was assessed by FITC-labeled BSA nanoparticles and immunofluorescent analysis was performed to track their relative distribution in the liver. Key findings The fabricated PTX@GL-BSA NPs were spherical structure with the particle size of 179 nm and a negative potential (−17.3 mV). Flow cytometry (FCM) studies exhibited that the accumulation of GL-BSA nanoparticles was 5.3-fold compared with BSA nanoparticles in HepG2 cells. The Nanoparticles were preferentially accumulated in the sinusoidal endothelial cells rather than the Kupffer cells. Conclusions This study provides useful information to understand the distribution of hepatic targeting nanoparticles when using GL-modified BSA nanoparticles, which helps to further use for effective treatment of liver disease.
