Extracellular Vesicles from Mesenchymal Stem Cells Reverse Neuroinflammation and Restore Motor Coordination in Hyperammonemic Rats.
Article in Journal of neuroimmune pharmacology : the official journal of the Society on NeuroImmune Pharmacology, 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
Cirrhotic patients may show minimal hepatic encephalopathy (MHE), with mild cognitive impairment and motor deficits. Hyperammonemia and inflammation are the main contributors to the cognitive and motor alterations of MHE. Hyperammonemic rats reproduce these alterations. There are no specific treatments for the neurological alterations of MHE. Extracellular vesicles from mesenchymal stem cells (MSC-EVs) are promising to treat inflammatory and immune diseases. We aimed to assess whether treatment of hyperammonemic rats with MSC-EVs reduced neuroinflammation in cerebellum and restored motor coordination and to study the mechanisms involved. The effects of MSC-EVs were studied in vivo by intravenous injection to hyperammonemic rats and ex vivo in cerebellar slices. Motor coordination was analyzed using the beam walking test. Effects on neuroinflammation were assessed by immunohistochemistry, immunofluorescence and Western blot. Injection of MSC-EVs reduced microglia and astrocytes activation in cerebellum and restored motor coordination in hyperammonemic rats. Ex vivo experiments show that MSC-EVs normalize pro-inflammatory factors, including TNFα, NF-kB activation and the activation of two key pathways leading to motor incoordination (TNFR1-NF-kB-glutaminase-GAT3 and TNFR1-CCL2-BDNF-TrkB-KCC2). TGFβ in the EVs was necessary for these beneficial effects. MSC-EVs treatment reverse neuroinflammation in the cerebellum of hyperammonemic rats and the underlying mechanisms leading to motor incoordination. Therapy with MSC-EVs may be useful to improve motor function in patients with MHE.
