Abstract

Gene targeting of the adaptor molecule DAP12 in mice caused abnormal distribution and impaired antigen presentation capacity of dendritic cells (DCs). However, the DAP12-associated receptors expressed on DCs and their functions have not been identified yet. Here we show that the triggering receptor expressed on myeloid cells-2 (TREM-2) is a cell surface receptor on human monocyte-derived DCs, which is associated with DAP12. TREM-2/DAP12 promotes upregulation of CC chemokine receptor 7, partial DC maturation, and DC survival through activation of protein tyrosine kinases and extracellular signal-regulated kinase. In contrast to Toll-like receptor-mediated signaling, TREM2/DAP12 stimulation is independent of nuclear factor-kappaB and p38 stress-activated protein kinase. This novel DC activation pathway may regulate DC homeostasis and amplify DC responses to pathogens, explaining the phenotype observed in DAP12-deficient mice.

  • TREM2 associates with DAP12 to induce signal transduction, including recruitment and activation of SYK and calcium flux.

    “TREM2 associates with the immunoreceptor tyrosine-based activation motif (ITAM)–containing adaptor protein DAP12 to induce signal transduction, including recruitment and activation of spleen tyrosine kinase (SYK) and calcium flux24,25.”

    From PLCγ2 regulates TREM2 signalling and integrin-mediated adhesion and migration of human iPSC-derived macrophages (2021) · cites this paper as [25]

    The Results (page not specified) show that TREM-2 associates with DAP12 and that TREM-2 ligation causes calcium flux in human monocyte-derived dendritic cells. The Discussion identifies DAP12 as an ITAM-containing adaptor and reports PTK and ERK signaling, but our copy does not show recruitment or activation of SYK by TREM-2. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • TREM2 is induced in human monocytes and mouse bone marrow cells upon exposure to GM-CSF and CSF-1.

    “We have previously shown that TREM2 is induced in human monocytes and mouse bone marrow cells upon exposure to GM-CSF and CSF-1 (Bouchon et al., 2001; Turnbull et al., 2006).”

    From TREM2 Modulation Remodels the Tumor Myeloid Landscape Enhancing Anti-PD-1 Immunotherapy (2020) · cites this paper as Bouchon et al., 2001

    The Results section on immature monocyte-derived dendritic cells reports high TREM-2 expression after human monocytes were cultured with GM-CSF and IL-4. It does not report induction in mouse bone marrow cells or by CSF-1; in fact, TREM-2 was undetectable in human monocyte-derived macrophages cultured with M-CSF. No page number is available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • TREM2 expression was first observed in macrophages and dendritic cells, but not granulocytes or monocytes.

    “TREM2 expression was first observed in macrophages and dendritic cells, but not granulocytes or monocytes (9–11).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
