The IL-33 expression levels in the liver biopsy IHC (relative expression 5.4 ± 1.0 vs. 3.0 ± 0.5, p = 0.0229, Figure 3B) and serum (305.1 ± 102.2 vs. 131.1 ± 32.3 pg/ml, p = 0.0502, Figure 3C) were significantly higher in patients with a Masson score of 3, indicating that IL-33 can be related to liver fibrosis stage. Here, IL33 is linked to Hepatic fibrosis.
