Triggering receptor expressed on myeloid cells 2 (TREM2) is a membrane protein that forms a receptor signaling complex with TYROBP and triggers activation of the immune responses in macrophages and dendritic cells. This protein is expressed on macrophages and dendritic cells but not on granulocytes or monocytes. In the CNS strongest expression seen in the basal ganglia, corpus callosum, medulla oblongata and spinal cord. It may have a role in chronic inflammations and may stimulate production of constitutive rather than inflammatory chemokines and cytokines. Defects in TREM2 are a cause of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL).
