WebJun 1, 2024 · The consequent wave of ROS-induced cell death triggers the release of damage-associated molecular patterns (DAMPs) by hepatocytes. DAMPs are innocuous intracellular constituents that become potent triggers of the innate immune system once released into the circulation [ 2, 7]. WebDAMPs released by hepatocyte necroptosis can induce a severe pro-inflammatory response. Up-regulated levels of inflammation and oxidative stress in liver tissue are characteristic pathological changes of ALF and can further exacerbate hepatocyte damage. 49 We investigated whether SNRS could reduce the level of inflammation and oxidative …

WebDec 18, 2024 · Hepatocyte lipotoxicity is a feature of NASH and results in cell and organelle stress, apoptosis, and the release DAMPs. Then, these DAMPs can activate TLRs, leading to a perpetuation in the inflammatory and cell death signals. The interplay between the immune system and hepatocytes contributes to the pathogenesis of NASH as well. WebNov 1, 2024 · The hepatocytes, recognize extracellular pathogen-associated molecular patterns (PAMPs) and intracellular damage-associated molecular patterns (DAMPs) through the above receptors. After the activation of the innate immune receptors, the hepatocytes produce cytokines, such as interferon (IFN), to protect the liver, through a series of …
WebDec 23, 2024 · In liver homeostasis, a balance between the loss and replacement of hepatocytes occurs in a highly regulated manner. Liver regeneration is closely associated with its capacity for xenobiotic and toxin-detoxifying functions after excessive exposure to insults such as food-derived toxins or infections by viruses, bacteria, and/or parasites … WebOct 10, 2024 · DAMPs from apoptotic hepatocytes thus is superposed by the recognition of P AMPs from gut bacteria. In this regard, ALD does not represent a tr ue sterile inflammatory liver disease. 5.
WebToll-like receptors (TLRs) and the cyclic GMP-AMP (cGAMP) synthase (cGAS) are the two major PRRs in hepatocytes and resident innate immune cells in the liver. Increasing evidence indicates that the overactivation of TLRs and the cGAS signaling pathways may contribute to the development of liver disorders, including NAFLD progression. WebJun 24, 2024 · Kupffer Cells-Hepatocytes. The DAMPs, such as cytosolic proteins, purine nucleotides, and mitochondrial compounds, primarily acted on pattern recognition …
WebThe relevant factors are elucidated and discussed. For instance, N-acetyl-p-benzoquinone imine (NAPQI) protein adducts trigger mitochondrial oxidative/nitrosative stress during hepatocyte necrosis, danger-associated molecular patterns (DAMPs) are released to elicit sterile inflammation, and certain growth factors contribute to liver regeneration.
