IL1B and Hepatic fibrosis: The nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome blockade normalized hepatic caspase-1 and IL-1β expression and reduced liver fibrosis in MCD diet-fed mice.343 Cytochalasin B, an endocytic inhibitor, eliminated the increased secretion of inflammatory factor IL-1β and the expression of α-smooth muscle actin (α-SMA) in HSCs that internalized NLRP3 inflammasome particles.344 Ghrelin is a gut hormone with 28-amino acid peptide.
