Core Tip

Core Tip: Triggering receptor expressed on myeloid cells 2 (TREM2) is an immunoglobulin superfamily receptor located on the cell membrane. In the liver, it is mainly expressed on macrophages. TREM2 plays an important regulatory role in lipid metabolism, inflammation, fibrosis, and hepatocellular carcinoma, and is considered a potential therapeutic target for non-alcoholic fatty liver disease (NAFLD) (for example, macrophages with high expression of TREM2 can effectively clear apoptotic liver cells in a timely manner), thereby inhibiting chronic liver inflammation and non-alcoholic steatohepatitis lesions caused by obesity. This article highlights the most recent research developments on TREM2 in NAFLD, in an attempt to identify new pathways for NAFLD treatment.
