Alleviation of Microglia Mediating Hippocampal Neuron Impairments and Depression-Related Behaviors by Urolithin B via the SIRT1-FOXO1 Pathway.
Article in CNS neuroscience & therapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
aimsConventional antidepressants exhibit limited efficacy and delayed onset. This study aimed to elucidate the antidepressant effects of urolithin B (UB) and its regulatory role in microglia-mediated hippocampal neuronal dysfunction.
methodsThe mouse model of depression was established using both chronic unpredicted stress (CUS) and lipopolysaccharide (LPS) injection. The therapeutic efficacy of UB was assessed through behavioral paradigms. The microglia activation, cellular cytotoxicity and apoptosis levels, and underlying molecular mechanisms were delineated utilizing proteomics analysis, immunofluorescence staining, real-time PCR and Western blotting.
resultsUB efficiently alleviated depression-related behaviors, accompanied by suppressed microglia activation, neuroinflammation, changes of classic activation (M1)/alternative activation (M2) polarization and recovered sirtuin-1 (SIRT1) and forkhead box protein O1 (FOXO1) expression in the hippocampus. Additionally, UB reduced the cytotoxicity and apoptosis of HT22 cells and depression-related phenotypes treated by the cellular supernatant from LPS-incubated BV2 cells, which was mediated by the SIRT1-FOXO1 pathway. The proteomics analysis of the cellular supernatant content revealed abundant secreting proteins among the LPS/UB application.
conclusionThis study confirmed that microglial SIRT1 mediates UB's antidepressant effects, positioning UB as a promising therapeutic candidate for depression by targeting neuroinflammatory pathways.
