Evaluation of the uptake of aluminum salt nanoparticles and microparticles by THP-1 cells in culture. THP-1 cells (6 × 105/well) were differentiated and incubated with aluminum hydroxide particles (i.e. AH-MPs or AH-NPs) (A) or aluminum phosphate particles (i.e. AP-MPs or AP-NPs) (B) at 37°C or 4°C for 3 h. Cells were then washed with cold PBS three times, and the amounts of aluminum obtained from the cells were determined and normalized to total protein content. The numbers of 37 and 4 in the X-axis are the temperature (°C) at which the cells and particles were co-incubated. Data are mean S.D. (n = 3).
