TEM ultrastructural study. Monocytes were loaded at different time points with either 50 μg/mL PLGA NPs (a 15 min; b 30 min; c 24 h) or PLGA/PEI NPs (d 15 min; e 30 min; f 24 h). Clathrin-dependent (g and i) and caveolin-dependent (j and k) pathways; multivesicular enodosomes (MVE) (h); interactions between vesicles and nuclear membrane (l) at 24 h post loading. NP internalization is indicated by asterisks. M: cytoplasmic membrane, N: nucleus, R: endoplasmic reticulum, m: mitochondria
