Microglial Clearance of Alzheimer's Amyloid-Beta Obstructed by Nanoplastics.
Article in Environmental science. Nano, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
Understanding the neurological impact of nanoplastic exposure has become an area of intensive research recently. This study examined the molecular and cellular mechanisms of how nanoplastics affect amyloid-beta (Aβ) clearance by microglia in the context of Alzheimer's disease (AD). Transmission electron microscopy and molecular dynamics simulations showed that polystyrene nanoplastics accelerated Aβ aggregation by forming a protein corona, promoting peptide fibrillization through hydrogen bonding and π-π interactions. Flow cytometry and endocytosis inhibition assays revealed that polystyrene nanoplastics impaired microglial uptake of Aβ while increasing their own cellular internalization, leading to microglial energy depletion and allowing Aβ aggregates to evade immune clearance. Additionally, proteomic analysis indicated that polystyrene nanoplastics disrupted microglial homeostasis, exacerbated neuroinflammation and metabolic dysregulation, and impaired the signalling pathway of ABC transporters critical for Aβ clearance in the AD brain. These findings suggest that nanoplastics contribute to AD pathology by impeding Aβ clearance and corrupting neuroimmune defense.
