Abstract |
To investigate the effects of ultrasmall superparamagnetic iron oxide (USPIO) labeling on the maturity or immune tolerance of immature dendritic cells (imDCs) as the success of immunotherapy with immature dendritic cells is highly dependent on immune tolerance. The feasibility of tracking implanted USPIO-labeled imDCs in vivo by magnetic resonance imaging (MRI) was explored. The effects of USPIO labeling on the immune tolerance of imDCs was examined. USPIO when higher than 200 μg/ml caused considerable damage to imDCs, induced imDC maturation, and impacted the immune tolerance of imDCs. USPIO labeling caused a dose-dependent increase in autophagosome formation in imDCs, and autophagy inhibitors prevented the maturation of imDCs while stimulating their immune tolerance. We speculate that high concentrations of USPIO can be used to induce imDC maturation, and that this process is likely mediated through an autophagy-related pathway. |
