Our previous study showed that glycyrrhizin (GLY) inhibited porcine epidemic
diarrhea virus (PEDV) infection, but the mechanisms of GLY anti-PEDV action
remain unclear. In this study, we focused on the anti-PEDV and
anti-proinflammatory cytokine secretion mechanisms of GLY. We found that PEDV
infection had no effect on toll-like receptor 4 (TLR4) protein and mRNA levels,
but that TLR4 regulated PEDV infection and the mRNA levels of proinflammatory
cytokines. In addition, we demonstrated that TLR4 regulated p38 phosphorylation
but not extracellular regulated protein kinases1/2 (Erk1/2) and c-Jun N-terminal
kinases (JNK) phosphorylation, and that GLY inhibited p38 phosphorylation but not
Erk1/2 and JNK phosphorylation. Therefore, we further explored the relationship
between high mobility group box-1 (HMGB1) and p38. We demonstrated that
inhibition of HMGB1 using an antibody, mutation, or knockdown decreased p38
phosphorylation. Thus, HMGB1 participated in activation of p38 through TLR4.
Collectively, our data indicated that GLY inhibited PEDV infection and decreased
proinflammatory cytokine secretion via the HMGB1/TLR4-mitogen-activated protein
kinase (MAPK) p38 pathway.
