Interactions between innate immune cells (left frame) and adaptive immune cells (right frame) on hepatocytes that promote NASH and the transition to hepatocellular carcinoma (HCC). NK cell: Natural killer cell; CD4+: CD4+ helper T cell; CD8+: Cytotoxic CD8+ T cells; Tregs: regulatory T-cells; DAMPs: damage associated molecular patterns; IFN: interferon; ROS: reactive oxygen species; MPO: myeloperoxidase; TNF: tumor necrosis factor; TLR: toll-like receptor; TRAIL: tumor necrosis factor-related apoptosis-inducing ligand; OSEs: oxidative stress-derived epitopes; OPN: Osteopontin; VCAM: vascular cell adhesion molecule; IL: interleukin; PDL: programed death ligand.
