Patients with acute-on-chronic liver failure (ACLF) usually exhibit defective monocyte function and excessive systemic inflammatory response. Interleukin-33 (IL-33) acts as a danger-associated molecular pattern (DAMP) to modulate immune response. However, the role of IL-33 in regulating monocyte function during hepatitis
