Abstract

Amyloid Binding Partners: Amyloid-β (Aβ) is critical to the pathology of Alzheimer's disease (AD), but its role in normal physiology remains unclear. Kim et al. (p. 1399 ; see the Perspective by Benilova and De Strooper ) found that murine-paired immunoglobulin-like receptor B (PirB) and its human ortholog, leukocyte immunoglobulin-like receptor B2 (LilrB2) both bound to oligomerized Aβ. Early in mouse development, ocular dominance plasticity was affected by interactions between oligomeric Aβ and PirB. In hippocampal brain slices from a mouse model of AD, reductions in long-term potentiation induced by Aβ required PirB. Furthermore, the memory defects characteristic of a mouse model of AD were dependent on function of PirB. Many binding partners for Aβ have been identified, and so the extent to which these findings can be exploited therapeutically remains unclear.

  • Amyloid proteins can regulate immune responses by interacting with different immune receptors.

    “Researches revealed that amyloid proteins can regulate immune responses by interacting with different immune receptors.”

    From Oligomeric cystatin C supports the immunosuppressive activity of myeloid cells through interaction with inhibitory receptors (2025) · cites this paper as [3]

    The paper’s Abstract (page unavailable in our copy) reports that β-amyloid oligomers bind PirB and LilrB2, receptors associated with the immune system. It links that interaction to synaptic loss and impaired plasticity, not to regulation of immune responses. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Amyloid β interacts with immune inhibitory receptors, leading to suppression of immune cell activity.

    “Conversely, Aβ has also been reported to interact with immune inhibitory receptors, leading to suppression of immune cell activity and highlighting its context-dependent immunomodulatory capacity3.”

    From Oligomeric cystatin C supports the immunosuppressive activity of myeloid cells through interaction with inhibitory receptors (2025) · cites this paper as [3]

    The indexed paper reports that Aβ oligomers bind PirB and LilrB2, receptors associated with inhibitory signaling in the immune system. Its reported consequences of Aβ binding concern neuronal signaling and synaptic plasticity, not suppression of immune cell activity. The passages are indexed under “Abstract”; no page number is provided. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • SIGLEC11 and LILRB2 have already been linked to Aβ peptides/amyloid plaques.

    “Importantly, SIGLEC11 and LILRB2 have already been linked to Aβ peptides/amyloid plaques25,26.”
  • Binding between oAβ and PirB recruits cofilin-signaling modules, leading to actin depolymerization, resulting in synaptic dysfunction and cognitive deficits.

    “Therefore, binding between oAβ and PirB would recruit cofilin-signaling modules, which leads to actin depolymerization, resulting in synaptic dysfunction and cognitive deficits [93].”
  • Deletion of PirB rescued hippocampal LTP deficits induced by Aβ42 oligomers.

    “Deletion of PirB rescued hippocampal LTP deficits induced by Aβ42 oligomers.”

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.
