A Pilot Study Evaluating the Effect of Artesunate on Glymphatic-Related Fluid Transport in Parkinson's Disease Mouse Models In Vivo and Ex Vivo.
Article in CNS neuroscience & therapeutics, 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
aimsArtesunate (ART) has shown neuroprotective potential, but its effects on glymphatic-related fluid transport in Parkinson's disease (PD) remain unclear. This pilot study aimed to explore whether ART affects glymphatic-related fluid transport in a PD mouse model and to assess the feasibility of evaluating these changes in vivo.
methodsC57BL/6 WT and A53T mice (n = 6 each) were divided into four groups (WT, WT + ART, A53T, and A53T + ART) and treated with ART or DMSO for 7 days. Glymphatic-related fluid transport was assessed by dynamic MRI after intraventricular Gd-DTPA injection. Immunofluorescence evaluated α-syn, AQP4, and AQP4-GFAP colocalization, while transmission electron microscopy (TEM) assessed astrocytic end-feet integrity.
resultsART was associated with regionally heterogeneous changes in tracer-related MRI signal dynamics in both WT and A53T mice. In PD mice, ART was associated with partial restoration of AQP4 polarization in selected brain regions and improved perivascular astrocytic end-feet morphology, accompanied by reduced α-syn immunofluorescence signal in the substantia nigra.
conclusionART was associated with regionally heterogeneous changes in glymphatic-related fluid transport dynamics and AQP4 polarization in this pilot PD mouse study. These preliminary findings support further investigation of ART as a potential modulator of brain fluid transport-related pathways in PD.
