May have a role in chronic inflammations and may stimulate production of constitutive rather than inflammatory chemokines and cytokines. Forms a receptor signaling complex with TYROBP and triggers activation of the immune responses in macrophages and dendritic cells.
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.
Defects in TREM2 are a cause of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL) [MIM:221770]; also known as presenile dementia with bone cysts or Nasu-Hakola disease (NHD). PLOSL is a recessively inherited disease characterized by a combination of psychotic symptoms rapidly progressing to presenile dementia and bone cysts restricted to wrists and ankles. PLOSL has a global distribution, although most of the patients have been diagnosed in Finland and Japan, with an estimated population prevalence of 2x10(-6) in the Finns.

Immunohistochemistry (Frozen sections) - Anti-TREM2 antibody [RM0139-5J46] (ab86491)This image is courtesy of an abreview submitted by Dr Ruma Raha-Chowdhury.
IHC-Fr image of human blood vessels stained with Ab86491 (1:250). The fixed brain sections were permeabilized using 0.1% PBS-Triton X for 1h. 10% donkey serum was used for 1 hour at 24°C to block protein-protein interactions. The sections were then incubated with Ab8649 used at 1/250 dilution, overnight at +4°C. The secondary antibody was Alexa Fluor® 568 donkey anti-rat used at 1/1000 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Immunofluorescence analysis of 18 day rat embroyonic hypothalmic neurones labelling TREM2 with ab86491. Embryonic hypothalmic neuronal cells were cultured in a neurobasal media with B27 culture suppliment for three weeks and fixed with 2%PFA. A rat monoclonal Alexa fluoro® 568 (red) secondary was used at a concentration of 1/1000. Synaptophysin was counterstained with an Alexa fluoro® 488 (green) and nuclear DNA was stained with DAPI (blue).
