LAIR1 and Hepatic fibrosis: As extracellular matrix (ECM) collagen is a ligand of LAIR-1, the excessive deposition of which occurs in tissues in hepatic fibrosis, we analyzed the correlation between fibrosis markers (FibroScan value and AST-to-platelet ratio index [APRI] score) and LAIR-1 expression on T cells in the patients.
