Targeted Liposomal Co-Delivery Dopamine with 3-n-Butylphthalide for Effective Against Parkinson's Disease in Mice Model.
Article in International journal of nanomedicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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) is a multifactor-induced neurodegenerative disease with high incidence in the elderly population. We found for the first time that the combination of dopamine (DA) and 3-n-butylphthalide (NBP) has great potential for the synergistic treatment of PD. To further improve the therapeutic performance of the drugs, a brain-targeting liposomal co-delivery system encapsulating NBP and DA ((NBP+DA)-Lips-RVG29) was designed using a rabies virus polypeptide with 29 amino acids (RVG29) as the targeting ligand. Methods: The synergistic neuroprotective effects of NBP and DA were assessed in 6-OHDA-induced PC12 cells. Then, (NBP+DA)-Lips-RVG29 loading with NBP and DA at an optimal ratio was prepared using the thin-film hydration and sonication method. The physicochemical and biological characterization of (NBP+DA)-Lips-RVG29 were systemically investigated, and the therapeutic efficiency and underlying mechanisms of (NBP+DA)-Lips-RVG29 were also explored in vitro and in vivo. Finally, the safety of (NBP+DA)-Lips-RVG29 was evaluated. Results: The synergistic effects of NBP and DA peaked at 1:1 (NBP/DA, mol/mol). The functionalized liposomes showed significantly higher uptake efficiency and blood-brain barrier (BBB) penetration efficiency in vitro. After systemic administration, (NBP+DA)-Lips-RVG29 prolonged the blood circulation of drugs, enhanced BBB penetration and increased drug accumulation in the striatum, substantia nigra and hippocampus. Moreover, (NBP+DA)-Lips-RVG29 showed excellent neuroprotective effects in a cellular PD model of PC12 cells and improved therapeutic efficacy in a PD mouse model. Furthermore, the safety evaluation of (NBP+DA)-Lips-RVG29 revealed no systemic toxicity. Conclusion: NBP and DA exhibited the synergistic anti-PD effects. The RVG29-modified liposomes encapsulating NBP and DA contributed to the accumulation of drugs in the brain lesions area of PD and further improved treatment efficacy. Therefore, (NBP+DA)-Lips-RVG29 represents a promising strategy for the treatment of PD and other neurodegenerative diseases.
