Amyloid-β and Mitochondrial Membranes: A Missing Link in Alzheimer's Pathogenesis.
Review in Molecular neurobiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disorder marked by memory loss and cognitive decline, predominantly in the elderly (Alzheimer Disease International et al., 2015). Although amyloid-β peptide (Aβ), particularly in its oligomeric forms, has long been linked to AD pathogenesis (Chen 9:1205-1235 2017, Gaspar 2 394-400 2010), the mechanisms underlying its cellular toxicity remain unclear. Mitochondrial dysfunction is a consistent feature of AD (D'Alessandro 107:102713 2025), yet how Aβ drives these alterations is not fully understood. This review integrates recent evidence showing that Aβ accumulates on mitochondrial membranes (Cenini 21:3257-3272 2016, Manczak 23:5131-5146 2006, Sirk 5:1989-2003 2007), providing a mechanistic link between amyloid pathology and mitochondrial damage. We discuss how membrane-associated Aβ disrupts mitochondrial protein import by impairing the translocase of the outer membrane (TOM) complex (Cenini 21:3257-3272 2016, Sirk 5:1989-2003 2007) and interferes with voltage-dependent anion channel 1 (VDAC1) (Smilansky 52:30670-30683 2015), a key regulator of metabolite exchange and apoptosis. We further emphasize the role of mitochondria-associated membranes (MAMs) as critical sites for Aβ generation and transfer to mitochondria, where dysregulated cholesterol metabolism may amplify MAM activity and Aβ accumulation (Area-Gomez and Schon 38:90-96 2017, Monaghan 2:240287 2025). Altogether, we propose that mitochondrial membrane localization of Aβ is a central mechanism linking amyloid pathology to mitochondrial dysfunction in aging, highlighting new directions for mitochondria-targeted therapeutic strategies in AD.
