Abstract

Amyloid-beta (Aβ) is suggested to play a causal role in the pathogenesis of Alzheimer's disease (AD). Immunotherapies are among the most promising Aβ-targeting therapeutic strategies for AD. But, to date, all clinical trials of this modality have not been successful including Aβ vaccination (AN1792), anti-Aβ antibodies (bapineuzumab, solanezumab and ponezumab), and intravenous immunoglobulin (IVIG). We propose that one reason for the failures of these clinical trials may be the adverse effects of targeting the central clearance of amyloid plaques. The potential adverse effects include enhanced neurotoxicity related to Aβ oligomerization from plaques, neuroinflammation related to opsonized Aβ phagocytosis, autoimmunity related to cross-binding of antibodies to amyloid precursor protein (APP) on the neuron membrane, and antibody-mediated vascular and neuroskeletal damage. Overall, the majority of the adverse effects seen in clinical trials were associated with the entry of antibodies into the brain. Finally, we propose that peripheral Aβ clearance would be effective and safe for future Aβ-targeting therapies.

  • Knockout of the NLRP3 gene prevented the stressor treatment from increasing protein levels of mature IL-1β in the prefrontal cortex and hippocampus.

    “KO of the NLRP3 gene prevented the stressor treatment from increasing protein levels of mature IL-1β in the PFC and hippocampus.”

  • Exposure of wild-type mice to 2-h immobilization stress every day for 30 consecutive days induced a decrease in sucrose preference and social interaction, and an increase in immobility in the forced swim test.

    “They found that exposure of wild-type mice to immobilization induced a decrease in sucrose preference and social interaction, and an increase in immobility in the forced swim test.”

  • Studies by Alcocer-Gomez et al (2015) and Iwata et al (2015) provide strong evidence for a causal role for the NLRP3 inflammasome in the effects of stress on depressive-like behavior.

    “Clearly, the studies by Alcocer-Gomez et al (2015) and Iwata et al (2015) provide strong evidence for a casual role for the NLRP3 inflammasome in the effects of stress on depressivelike behavior.”

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.
