Accelerated and localized synucleinopathy in a hybrid mouse model: implications for positron emission tomography studies.
Article in Npj imaging, 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
Parkinson's disease (PD) is characterized by alpha-synuclein (α-syn) aggregation, dopaminergic (DA) neuron loss, and neuroinflammation. Synucleinopathy, the α-syn-related pathology, is the central to the pathogenetic processes observed in the brains of patients with PD, dementia with Lewy bodies (DLB), and multiple system atrophy (MSA). We are seeking an animal model with synucleinopathy that can comprehensively replicate these pathologies and adhere to suitable timeframes for preclinical research for positron emission tomography (PET) imaging studies. Adeno-associated virus (AAV) carrying the mutated human α-syn gene and S87N α-syn preformed fibrils (PFF) were co-injected into the left substantia nigra (SN) of mouse brains. Immunohistochemistry (IHC) and PET/CT imaging were performed at different time points to detect the key pathologies in the brain. This model resulted in accelerated α-syn pathology, detectable as early as two weeks post-injection, alongside DA neuron loss, microglial activation, reduced synaptic density, and impaired mitochondrial function within five weeks. Pathology remained spatially localized. In summary, this AAV/PFF hybrid model offers a rapid, region-specific platform for studying synucleinopathies such as PD, as well as for evaluating PET ligands for disease diagnosis and monitoring.
