In vitro cellular experiments of EAU therapy by the Fe-curcumin nanozyme. a Schematic illustration of the experiments. b Cell viability of PBMCs was determined via CCK8 assays. The experiment screened the most suitable drug concentration for cell experiments. c, d Laser scanning confocal microscopy images of DFCH-DA-stained RF/6A cells and strength analysis after different treatments. e, g. ^* P < 0.05 compared with the control group; ^# P < 0.05 compared with the LPS + IFN-γ alone group
