Abstract

In atherosclerosis and Alzheimer's disease, deposition of the altered self components oxidized low-density lipoprotein (LDL) and amyloid-beta triggers a protracted sterile inflammatory response. Although chronic stimulation of the innate immune system is believed to underlie the pathology of these diseases, the molecular mechanisms of activation remain unclear. Here we show that oxidized LDL and amyloid-beta trigger inflammatory signaling through a heterodimer of Toll-like receptors 4 and 6. Assembly of this newly identified heterodimer is regulated by signals from the scavenger receptor CD36, a common receptor for these disparate ligands. Our results identify CD36-TLR4-TLR6 activation as a common molecular mechanism by which atherogenic lipids and amyloid-beta stimulate sterile inflammation and suggest a new model of TLR heterodimerization triggered by coreceptor signaling events.

  • Amyloid-beta-mediated release of proinflammatory factors and neurotoxicity partially involves signaling through the CD36/TLR4/TLR6 complex.

    “Stewart and colleagues demonstrated that Aβ-mediated release of proinflammatory factors and neurotoxicity partially involved signaling through the CD36/ TLR4/TRL6 complex (108).”

    From Microglia in Alzheimer's disease (2017) · cites this paper as [108]

  • The CD36/TLR4/TLR6 co-receptor complex upregulates production of chemokines and cytokines such as pro-IL-1β through activation of NF-κB.

    “CD36 mediates heterodimer formation of TLR4 and TLR6 (REF. 104), and this co-receptor complex upregulates the production of chemokines and cytokines such as pro-IL-1β through the activation of NF-κb.”

    From Sterile inflammation: sensing and reacting to damage (2010) · cites this paper as [105]

  • Soluble Aβ oligomers and Aβ fibrils can react to various receptors expressed by microglia, including CD14, CD36, CD47, α6β1 integrin, class A scavenger receptor, RAGE and TLRs.

    “The Soluble Aβ oligomers and Aβ fibrils can react to various receptors expressed by microglia, including CD14, CD36, CD47, α6β1 integrin, class A scavenger receptor, receptor for advanced glycosylation end products (RAGE) and TLRs (Stewart et al., 2010).”
  • The binding of Aβ to CD36 promotes TLR4 and/or TLR6 phosphorylation and activation, resulting in production of inflammatory cytokines and chemokines.

    “The binding of Aβ to CD36 (cell surface microglial co-receptor) promotes the TLR4 and/or TLR6 phosphorylation and activation, resulting in the production of inflammatory cytokines and chemokines (Stewart et al., 2010).”

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.
