Mechanism of the protective effect of 2,3,5,4'-Tetrahydroxy stilbene-2-O-β-D-glucoside on MPTP-induced Parkinson's disease mice.
Article in Histology and histopathology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
background and purposeParkinson's disease (PD) is a common neurodegenerative disorder with a complex pathogenesis. 2,3,5,4'-Tetrahydroxy stilbene-2-O-β-D-glucoside (TSG) is one of the main active components of
methodsThe PD mouse model was constructed via the use of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). The PD process was evaluated via behavioral tests, HE staining, immunohistochemistry, and immunofluorescence. The levels of related proteins and inflammatory factors were detected via western blotting and ELISA. The effect of TSG on the intestinal flora of MPTP-induced PD mice was evaluated through 16S rDNA sequencing.
resultsTSG intervention can significantly alleviate motor dysfunction in PD mice, increase the number of TH-positive neurons in the substantia nigra, inhibit the accumulation of α-syn and glial cell activation, reduce the expression of the tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, iNOS, and COX2 proteins in the substantia nigra and colon, inhibit neuroinflammation and intestinal inflammation, decrease the levels of LPS, LBP, TNF-α, IL-1β, and IL-6 in the serum, suppress systemic inflammation, reduce damage to the blood-brain barrier (BBB) and intestinal barrier in PD mice, and restore species diversity and abundance of the intestinal flora in PD mice to a certain extent.
conclusionTSG can improve motor coordination ability, systemic and neuroinflammatory levels, BBB injury, intestinal barrier injury, and the intestinal flora composition of PD mice, suggesting that TSG has a protective effect on MPTP-induced PD mice.
