Time-dependent uptake of FPA/EPI NPs by KCs.
Notes: KCs were incubated with different endocytosis inhibitors for 2, 6, or 18 h prior to addition of 200 µg/mL FPA/EPI NPs, and the uptake percentage was quantified by fluorometry compared with untreated controls. Data are represented as mean ± SD of five determinations. *P<0.05, **P<0.01 compared to respective controls.
Abbreviations: AMR, amiloride; Col, colchicine; CPZ, chlorpromazine; FPA/EPI NPs, epirubicin-loaded folic acid-conjugated pullulan acetate nanoparticles; KCs, Kupffer cells; NY, nystatin; PDTC, pyrrolidine dithiocarbamate.
