Inflammatory cytokines and inflammatory stimuli can induce the upregulation of IL-37. However, it has not been reported whether anti-inflammatory medications induce the expression of IL-37. In this work, we uncovered, for the first time, that two main bioactive components, triptolide and triptonide, from the herb Tripterygium wilfordii Hook f. （TwHF）, which possess anti-inflammatory activity, upregulate the expression of IL-37, and this expression was suppressed by ERKI/2 and p38 MAPK inhibitors. Overall, our research demonstrated, for the first time, that anti-inflammatory active components （triptolide and triptonide） upregulated the expression of IL-37 most likely via activation of the ERKI/2 and p38 MAPK pathways.展开更多
