WebNevertheless, hepatocytes primarily damaged by APAP release damage-associated molecular patterns (DAMPs), which in turn result in the activation of innate immune cells and sterile inflammation . Thus, the immune cell involvement in the APAP overdose model is a late time event, and the anti-inflammatory effects of AITC may affect immune cells at ... WebMar 20, 2024 · However, when the chronic liver injury occurs, hepatocytes become necrotic and apoptotic, and damaged hepatocytes release damage-associated molecular patterns (DAMPs). DAMPs directly activate the fibrotic phenotype of HSCs, producing a large amount of ECM with type I and type III collagen and fibronectin as the main components.
