TREM2-Ligand Interactions in Health and Disease

Abstract

The protein triggering receptor expressed on myeloid cells-2 (TREM2) is an immunomodulatory receptor with a central role in myeloid cell activation and survival. In recent years, the importance of TREM2 has been highlighted by the identification of coding variants that increase risk for Alzheimer's disease and other neurodegenerative diseases. Animal studies have further shown the importance of TREM2 in neurodegenerative and other inflammatory disease models including chronic obstructive pulmonary disease, multiple sclerosis, and stroke. A mechanistic understanding of TREM2 function remains elusive, however, due in part to the absence of conclusive information regarding the identity of endogenous TREM2 ligands. While many TREM2 ligands have been proposed, their physiological role and mechanism of engagement remain to be determined. In this review, we highlight the suggested roles of TREM2 in these diseases and the recent advances in our understanding of TREM2 and discuss putative TREM2-ligand interactions and their potential roles in signaling during health and disease. We develop a model based on the TREM2 structure to explain how different TREM2 ligands might interact with the receptor and how disease risk variants may alter ligand interactions. Finally, we propose future experimental directions to establish the role and importance of these different interactions on TREM2 function.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • TREM2 binds lipids exposed on the surface of apoptotic cells, as well as ApoE and lipidated Amyloid beta (Aβ).

    “TREM2 binds lipids exposed on the surface of apoptotic cells [49, 50], as well as ApoE [51] and lipidated Amyloid beta (Aβ) [52].”

    From TREM2/PLCγ2 signalling in immune cells: function, structural insight, and potential therapeutic modulation (2021) · cites this paper as [52]

    In §3, “TREM2 binds anionic ligands on mammalian cells” (page unavailable), the review reports TREM2 binding to phospholipids in laboratory assays. It also reports increased binding to some apoptotic cells, but says it is unclear which ligand accounts for that binding; apoptotic Jurkat cells exposing phosphatidylserine did not bind Fc-TREM2. Thus, the cited source does not establish that the lipids exposed on apoptotic-cell surfaces are what TREM2 binds. The ApoE and Aβ clauses carry separate citations. (LLM, conf=0.88)

  • 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.”

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.
