In humans, the relevance of the IL-33/ST2 pathway to liver pathophysiology has been documented in liver failure (13), alcoholic hepatitis (14), and nonalcoholic steatohepatitis (15), suggesting a pivotal role of IL-33 in inflammatory liver diseases, but its role in LT has not been established yet. Here, IL33 is linked to metabolic dysfunction-associated steatohepatitis.
