Inhibition effect of amentoflavone on SS2-induced MAPK/NF-κB activation. J774 cells were infected with SS2 at different concentrations of amentoflavone (MOI = 10:1) for 6 h, and protein samples were analyzed by Western blotting. Immunoblots showing expression levels of phospho-p38, p38, phospho-JNK1/2, JNK1/2, phospho-NF-κB p65, and NF-κB p65. β-Actin was used as an internal control.
