As shown in Figure 5, CCl4 treatment could up‐regulate the pro‐inflammatory cytokines TNF‐α, IL‐6 and IL‐1β in the liver, and MulA treatment significantly reduced the levels of these cytokines, indicating that MulA might alleviate liver fibrosis via inhibiting inflammatory cytokines secretion. Here, IL1B is linked to Hepatic fibrosis.
