Extracellular vesicles from mesenchymal stem cells improve neuroinflammation and neurotransmission in hippocampus and cognitive impairment in rats with mild liver damage and minimal hepatic encephalopathy.
Article in Stem cell research & therapy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundPatients with steatotic liver disease may show mild cognitive impairment. Rats with mild liver damage reproduce this cognitive impairment, which is mediated by neuroinflammation that alters glutamate neurotransmission in the hippocampus. Treatment with extracellular vesicles (EV) from mesenchymal stem cells (MSC) reduces neuroinflammation and improves cognitive impairment in different animal models of neurological diseases. TGFβ in these EVs seems to be involved in its beneficial effects. The aim of this work was to assess if MSCs-EVs may improve cognitive impairment in rats with mild liver damage and to analyze the underlying mechanisms, assessing the effects on hippocampal neuroinflammation and neurotransmission. We also aimed to analyze the role of TGFβ in the in vivo effects of MSCs-EVs.
methodsMale Wistar rats with CCl
resultsUnmodified MSC-EVs reversed microglia activation and TNFα content, restoring membrane expression of NR2 subunit of NMDA receptor and improved object location memory. In contrast, EVs derived from TGFβ-silenced MSCs did not induce these effects but reversed astrocyte activation, IL-1β content and altered GluA2 AMPA receptor subunit membrane expression leading to improvement of learning and working memory in the radial maze.
conclusionsEVs from MSCs with TGFβ silenced induce different effects on behavior, neuroinflammation and neurotransmitter receptors alterations than unmodified MSC-EVs, indicating that the modification of TGFβ in the MSC-EVs has a notable effect on the consequences of the treatment. This work shows that treatment with MSC-EVs improves learning and memory in a model of mild liver damage and MHE in rats, suggesting that MSC-EVs may be a good therapeutic option to reverse cognitive impairment in patients with steatotic liver disease.
