Study of the mechanism of internalization for CTxB-FMSN material in HeLa cells. a) Schematic representation of the possible endocytosis pathways for CTxB-FMSNs. b) Flow cytometry results for the inhibition of macropinocytosis (MPC), clathrin-mediated endocytosis (CME), caveolin-mediated endocytosis (CavME), double (DI) (MPC/CME) and triple (TI) (MPC/CME/CavME) inhibition for FMSNs (blue), PEGC-MSNs (red) and CTxB-FMSNs (green). Data represent ± SEM of triplicates from 3 independent experiments. Data are represented in relation to untreated control (100%). Asteriks indicate p < 0.02.
