Figure 5. Analysis of secreted IL-6 and IL-8 cytokine concentrations. HCE cells were incubated with PBS (clear square) or HMW-HA (black square) and irradiated with various doses (0, 25, 75, and 150 mJ/cm2) of UVB. The concentration of secreted IL-6 (A) and IL-8 (B) cytokines in the cell culture supernatant of HCE cells was determined by ELISA 24 h after irradiation. Data are mean±SD of three independent experiments. Differences were significant at p<0.05 (one asterisk), p<0.01 (two asterisks), and p<0.001 (three asterisks) compared to the PBS group of each UVB dose.
