Mechanism for uptake of silica particles by monocytic U937 cells.


We examined the mechanism for uptake by monocytic cells of particles found in the atmosphere of some industrial work places. As a model system, irregular crystalline silica particles (SPs), sphere-like cryptocrystalline microsilica particles (MPs) and carbon particles (CPs) were exposed to pro-monocytic U937 cells. Plasma-treated SP and MP, but not CP… (More)
