Cellular actions of beta-amyloid precursor protein and its soluble and fibrillogenic derivatives

Mattson, M. P.·1997·Physiological Reviews

Abstract

beta-Amyloid precursor protein (beta-APP), the source of the fibrillogenic amyloid beta-peptide (A beta) that accumulates in the brain of victims of Alzheimer's disease, is a multifunctional protein that is widely expressed in the nervous system. beta-Amyloid precursor protein is axonally transported and accumulates in presynaptic terminals and growth cones. A secreted form of beta-APP (sAPP alpha) is released from neurons in response to electrical activity and may function in modulation of neuronal excitability, synaptic plasticity, neurite outgrowth, synaptogenesis, and cell survival. A signaling pathway involving guanosine 3',5'-cyclic monophosphate is activated by sAPP alpha and modulates the activities of potassium channels, N-methyl-D-aspartate receptors, and the transcription factor NF kappa B. Additional functions of beta-APP may include modulation of cell adhesion and regulation of proliferation of nonneuronal cells. Alternative enzymatic processing of beta-APP liberates A beta, which has a propensity to form amyloid fibrils; A beta can damage and kill neurons and increase their vulnerability to excitotoxicity. The mechanism involves generation of oxyradicals and impairment of membrane transport systems (e.g., ion-motive ATPases and glutamate and glucose transporters). Genetic mutations or age-related metabolic changes may promote neuronal degeneration in Alzheimer's disease by increasing production of A beta and/or decreasing levels of neuroprotective sAPP alpha.

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.
