Contrast agents based on dextran-coated superparamagnetic iron oxide nanoparticles (SPIO) are internalized by professional phagocytes such as hepatic Kupffer cells, yet their role in phagocyte biology remains largely unknown. Here we investigated the effects of the SPIO ferucarbotran on murine Kupffer cells and human macrophages. Intravenous injection of ferucarbotran into mice led to rapid accumulation...
Superparamagnetic iron oxide nanoparticles are frequently used for cell labeling or as diagnostic contrast media, yet studies analyzing their effects on immune cells remain scarce. Here we investigated how nanosized carboxydextran-coated superparamagnetic iron oxide (SPIO) and ultrasmall superparamagnetic iron oxide (USPIO) might affect human macrophages. Within 1 h, both SPIO and USPIO were rapidly...
