Paeonol Mitigates Neurodegeneration: Molecular Insights into Its Anti-inflammatory, Antioxidant, and Synaptoprotective Mechanisms.
Review in Molecular neurobiology, 2025. 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
Neurodegeneration is the gradual atrophy of the structure and functionality of the neurons, which culminates in the death of the neurons. This pathological process is central to numerous neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease. The global prevalence of neurodegenerative diseases is increasing rapidly, posing a significant public health burden. The various interconnected molecular pathways are disrupted in the pathogenesis of neurodegenerative diseases. Among them, TLR/MyD88/NF-κB and MAPK/NF-κB signaling cascades are critical ones that activate neuroinflammation. Whereas, NLRP3 inflammasome-mediated pyroptosis contributes to inflammatory cell death. Moreover, the BDNF/Trk-B-mediated PI3K/Akt/mTOR pathway controls the synaptic plasticity that is necessary in the learning and memory processes. In addition, caspase and AIF-mediated apoptotic signaling pathways are disrupted in neurodegenerative diseases. Till now, various natural phenolic compounds have shown high potential in combating different neurodegenerative diseases. Paeonol is a 2'-hydroxy-4'-methoxyacetophenone, commonly found in the root bark of Paeonia suffruticosa and other Paeonia species. It possesses diverse pharmacological actions, including neuroprotection, anti-inflammatory, antioxidant and cardioprotective. Various cell lines and preclinical reports have documented that paeonol confers neuroprotection through modulation of various mediators, including TLR4, MAPK, PI3K, mTOR, BDNF, NF-κB, ROS, AMPK, NLRP3, apoptotic proteins and inflammatory mediators, among others. Given that paeonol can modulate these mediators, the current study was designed to investigate the mechanistic interactions that underlie its neuroprotective effects. Examining these interrelated pathways will give future researchers the fundamental knowledge to fill the existing gaps and better understand the potential of paeonol in neurodegenerative diseases.
