TREM2: Function, Clinical significance & Structure

Triggering receptor expressed on myeloid cells 2 (TREM2) is a protein that in humans is encoded by the TREM2 gene. TREM2 is expressed on macrophages, immature monocyte-derived dendritic cells, osteoclasts, and microglia, which are immune cells in the central nervous system. In the liver, TREM2 is expressed by several cell types, including macrophages…
