Core Tip

Core tip: We successfully established an in vitro cell model of alcoholic liver fibrosis (ALF). We investigated the influence of interleukin (IL)-22 on ALF and the possible mechanism involved. To our knowledge, this is the first study to confirm the inhibitory effect of IL-22 on ALF at the cellular level. We found that the effect was at least partly related to promotion of nuclear translocation of nuclear factor-related factor (Nrf)2 and increased activity of the antioxidant axis Nrf2-keap1-ARE. We aimed to provide a new target for research on ALF and new drug development.
