In the liver, this cytokine was reported to promote the progression from steatosis to non‐alcoholic steatohepatitis (NASH) by upregulating the expression of hepatocyte‐derived IL‐8 and chemokine CXCL1 to recruit neutrophils [95, 96, 97]. The gene discussed is CXCL1; the disease is metabolic dysfunction-associated steatohepatitis.
