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]. 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.
