Polyunsaturated fatty acids in lipid membranes regulate human neuronal function and amyloid-β production.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
The effects and mechanisms of polyunsaturated fatty acids (PUFAs) including docosahexaenoic acid (DHA) and arachidonic acid (ARA) contained in the lipid membrane of neurons in the production of amyloid β (Aβ), a pathogenic molecule in Alzheimer's disease (AD), remain unclear. In this study, we cultured human cortical neurons differentiated from induced pluripotent stem cells (iPSCs) under conditions of PUFA deficiency being progressively alleviated. Under PUFA-deficient conditions, increasing the total PUFA composition ratio in the lipid membrane enhanced membrane fluidity and reduced Aβ production. Furthermore, in conditions where the overall PUFA deficiency was resolved, altering the specific ratios of DHA and ARA promoted the synchronous activity and morphological complexity of neuronal cells while maintaining consistent membrane fluidity. These findings demonstrate that the overall PUFA composition in the lipid membrane as well as the specific ratios of DHA and ARA within the total PUFAs regulate neuronal function and pathophysiology.
