SVHRSP protects against rotenone-induced neurodegeneration in mice by inhibiting TLR4/NF-κB-mediated neuroinflammation via gut microbiota.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Strong evidence indicates that remodeling gut microbiota may be an effective approach to combat Parkinson's disease (PD). Scorpion Venom Heat-Resistant Synthesized Peptide (SVHRSP), a synthesized peptide discovered from scorpion venom, displays potent neuroprotection in multiple PD models. However, the potential mechanisms remain unclear. In this study, we demonstrated that SVHRSP effectively attenuated gastrointestinal function impairments and reinstated the microbiota composition in rotenone-induced PD mouse model. Microbiota depletion and FMT verified that the restored gut microbiota was necessary for SVHRSP-mediated neuroprotection against dopaminergic neurodegeneration in rotenone PD mice. Furthermore, SVHRSP gut microbiota-dependently attenuated BBB impairment, microglial activation, and gene expression of pro-inflammatory factors in rotenone-treated mice. Mechanistically, SVHRSP decreased the concentrations of LPS and HMGB1 in both serum and brain tissue, thereby inhibiting the TLR4/NF-κB signaling pathway in the brain of rotenone-treated mice. Together, our findings provided fresh perspectives on the mechanisms underlying SVHRSP-induced neuroprotection in PD.
