The concentrations of HMGB1 protein for the results shown in Figure 1d were: uninfected controls (1005.67 ± 340.00 pg/mL), virus infection (1471.50 ± 345.28 pg/mL), infection by UV-inactivated virus (1174.00 ± 352.43 pg/mL), and treatment by 200 μM of glycyrrhizin (227 ± 99.60 pg/mL) (Figure 1d). Here, HMGB1 is linked to viral infectious disease.
