ROS scavenging ability of LR@PDH. a, b DCF fluorescence intensity within LR, LR@HA and LR@PDH after incubation with H2O2 were detected by flow cytometry. c DCF fluorescence intensity in the supernatant containing 400 μM H2O2 after treated with PBS, LR, LR@HA and LR@PDH. d Schematic of HGFs cells co-cultured with probiotics in the Transwell system. e Representative images and f quantitative analysis of intracellular ROS levels of HGFs cells treated with 200 μmol/L H2O2 after co-cultured with PBS, LR, LR@HA and LR@PDH. *P < 0.05 and ****P < 0.000 1. The data are presented as mean ± SD, n = 3
