The activation of HSCs regulated by other cells in liver fibrosis. Extracellular components from injured hepatocytes, Kupffer cells, macrophages, NK cells, T and B lymphocytes modulate HSCs activation via various cytokines. LSECs inhibit or promote the activation of HSCs in different conditions. NK cells kill activated HSCs in IFNγ and TRAIL-dependent ways. TRAIL, TNF-related apoptosis-inducing ligand
