Abstract

Accumulation of neurotoxic amyloid peptides (Aβ) in the brain, generated by β-site proteolytic processing of the amyloid precursor protein (APP), is the hallmark pathophysiologic feature of Alzheimer's disease. The plasmin-activating cascade, in which urokinase (uPA) and tissue-type (tPA) plasminogen activators convert plasminogen to the broad-spectrum protease plasmin, appears to serve a protective, Aβ-clearing, role in the central nervous system. Plasmin degrades Aβ and catalyzes α- site APP proteolysis generating nontoxic peptides. Plasmin activation in the brain is negatively regulated by the fast-acting clade E serine protease inhibitor (SERPIN) plasminogen activator inhibitor type-1 (PAI-1; SERPINE1) resulting in Aβ accumulation. PAI-1 and its major physiological inducer TGF-β1, moreover, are both increased in Alzheimer's disease models and implicated in the etiology and progression of human neurodegenerative disorders. Current findings support the hypothesis that targeting of PAI-1 function (by small molecule drugs) and/or gene expression (by histone deacetylase inhibitors) may constitute a clinically-relevant molecular approach to the therapy of neurodegenerative diseases associated with increased PAI-1 levels.

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.
