Abstract

Alzheimer’s disease (AD) is the most common neurodegenerative disease. There are many studies targeting extracellular deposits of amyloid β-peptide (Aβ) and intracellular neurofibrillary tangles (NFTs), however, there are no effective treatments to halt the progression. Mitochondria-associated endoplasmic reticulum membranes (MAMs) have long been found to be associated with various pathogenesis hypotheses of AD, such as Aβ deposition, mitochondrial dysfunction, and calcium homeostasis. However, there is a lack of literature summarizing recent advances in the mechanism and treatment studies. Accordingly, this article reviews the latest research involving the roles of MAM structure and tethering proteins in the pathogenesis of AD and summarizes potential strategies targeting MAMs to dissect treatment perspectives for AD.

  • Abnormal localization of APP to MAM alters γ-secretase function and enhances Aβ generation.

    “Mechanistically, abnormal localization of APP to mitochondria-associated membranes alters γ-secretase function and enhances Aβ generation [61], while mitochondrial oxidative stress activates kinases such as GSK3β and CDK5, promoting tau hyperphosphorylation [62].”

    From Toward a Unified Framework in Molecular Neurobiology of Alzheimer’s Disease: Revisiting the Pathophysiological Hypotheses (2026) · cites this paper as [61]

    The section “The role of MAMs in Aβ generation of AD” (page unavailable) says APP and γ-secretase are found in MAMs, where APP-derived C99 is cleaved to produce Aβ. It also reports that reducing ER–mitochondria contact lowers γ-secretase activity and Aβ levels. It does not establish that abnormal localization of APP itself alters γ-secretase function or enhances Aβ generation. (LLM, conf=0.86)

    “They are not the collection of membranes but the employment of the proteinaceous tethers (Rowland and Voeltz, 2012), which play a key role in many important metabolic processes including the transfer of calcium, mitochondrial dynamics, lipid synthesis, autophagy, apoptosis, and inflammation.”

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.
