Abstract

Epidemiological studies have documented a reduced prevalence of Alzheimer's disease among users of nonsteroidal anti-inflammatory drugs (NSAIDs). It has been proposed that NSAIDs exert their beneficial effects in part by reducing neurotoxic inflammatory responses in the brain, although this mechanism has not been proved. Here we report that the NSAIDs ibuprofen, indomethacin and sulindac sulphide preferentially decrease the highly amyloidogenic Abeta42 peptide (the 42-residue isoform of the amyloid-beta peptide) produced from a variety of cultured cells by as much as 80%. This effect was not seen in all NSAIDs and seems not to be mediated by inhibition of cyclooxygenase (COX) activity, the principal pharmacological target of NSAIDs. Furthermore, short-term administration of ibuprofen to mice that produce mutant beta-amyloid precursor protein (APP) lowered their brain levels of Abeta42. In cultured cells, the decrease in Abeta42 secretion was accompanied by an increase in the Abeta(1-38) isoform, indicating that NSAIDs subtly alter gamma-secretase activity without significantly perturbing other APP processing pathways or Notch cleavage. Our findings suggest that NSAIDs directly affect amyloid pathology in the brain by reducing Abeta42 peptide levels independently of COX activity and that this Abeta42-lowering activity could be optimized to selectively target the pathogenic Abeta42 species.

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

  • Anti-inflammatory drugs such as NSAIDs have been used as a potential treatment in Alzheimer's disease because of their capacity to bind to and stimulate PPAR-γ as well as their direct effects on amyloid formation.

    “Anti-inflammatory drugs such as NSAIDs have been used as a potential treatment in AD because of their capacity to bind to and stimulate the nuclear receptor peroxisome proliferator-activated receptor (PPAR)-γ as well as their direct effects on the amyloid formation [101].”
  • The first gamma-secretase modulators were discovered by recognizing that ibuprofen, indomethacin, and sulindac reduce Aβ42 levels through modulation of gamma-secretase activity.

    “The first GSMs were discovered by recognizing that ibuprofen, indomethacin and sulindac reduce Abeta42 levels (Weggen et al., 2001) through modulation of gamma-secretase activity (Eriksen et al., 2003).”

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.
