Sulfate reducing bacteria induce α-synuclein in intestinal and neuronal cells and tissues and inhibit tyrosine hydroxylase in neuronal cells.

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
Introduction: Parkinson's disease (PD), a synucleopathy characterized by the presence of α-synuclein (α-syn) aggregates in the brain, is thought to originate in the intestine. Methods: Enteroendocrine STC-1 and neuronal SH-Sy5y cells were infected with Results: We found that DSV increased the number of STC-1cells with α-syn aggregates and also induced α-syn expression in these cells. Sup from DSV-infected STC-1 had higher α-syn levels compared to control uninfected sup and could induce α-syn aggregates in SH-Sy5y. DSV also directly induced a syn aggregates and inhibited TH in SH-Sy5y. DSV-gavaged mice had higher levels of α-syn in the duodenum, plasma, and in brain and also showed a decreasing trend in TH expression in the brain. Conclusion: Thus, our findings provide a gut-to-brain link tied to the ability of SRB in the gut-to increase expression, aggregation and spread of α-syn and decrease of TH in PD.
