  • Function

    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.
  • Tissue specificity

    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.
  • Involvement in disease

    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.

  • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized SK-N-F1 cells labeling TREM2 with ab209814 at 1/500 dilution, followed by Donkey anti rabbit IgG (Alexa Fluor® 488) secondary antibody at 1/1000 dilution (green).

    The nuclear counter stain is DAPI (blue).

  • TREM2 was immunoprecipitated from 0.35 mg of THP-1 (Human monocytic leukemia cell line) whole cell lysate with ab209814 at 1/40 dilution. Western blot was performed from the immunoprecipitate using ab209814 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: THP-1 whole cell lysate, 10 μg (Input).

    Lane 2: ab209814 IP in THP-1 whole cell lysate.

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab209814 in THP-1 whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 3 minutes.
