Pterostilbene protects against lipopolysaccharide-induced inflammation and blood-brain barrier disruption in immortalized brain endothelial cell lines in vitro.
Article in Scientific reports, 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
Brain microvascular endothelial cells are connected by tight junction (TJ) proteins and interacted by adhesion molecules, which participate in the selective permeability of the blood-brain barrier (BBB). The disruption of BBB is associated with the progression of cerebral diseases. Pterostilbene is a natural compound found in blueberries and grapes with a wide range of biological activities, including anti-inflammatory, antioxidant, and anti-diabetic effects. In this study, we investigated the protective effects of pterostilbene on LPS-stimulated mouse brain endothelial (bEnd.3) cells and underlying mechanisms. The results showed that pterostilbene effectively upregulated the expressions of tight junction (TJ) proteins such as zonula occludens (ZO)-1 and claudin-5 and downregulated the expression of adhesion molecules such as intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1, preventing BBB damage under LPS stimulation. Pterostilbene decreased the LPS-triggered expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 as well as the levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α and nitric oxide (NO). Meanwhile, we found that pterostilbene exerted an inhibitory effect on nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) pathways in bEnd.3 cells upon LPS stimulation. Additionally, pterostilbene exhibited antioxidant effects by activating heme oxygenase 1 (HO-1). These findings indicated that pterostilbene protected against lipopolysaccharide (LPS)-induced inflammation, oxidative stress and blood-brain barrier (BBB) disruption in bEnd.3 cells.
