Dengue virus NS1 hits hard at the barrier integrity of human cerebral microvascular endothelial cells via cellular microRNA dysregulations.
Article in Tissue barriers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
Dengue virus (DENV) infections are commonly reported in the tropical and subtropical regions of the world. DENV is reported to exploit various strategies to cross the blood-brain barrier. The NS1 protein of DENV plays an important role in viral neuropathogenesis, resulting in endothelial hyperpermeability and cytokine-induced vascular leak. miRNAs are short non-coding RNAs that play an important role in post-transcriptional gene regulations. However, no comprehensive information about the involvement of miRNAs in DENV-NS1-mediated neuropathogenesis has been explored to date. We observed that DENV-NS1 significantly alters the cellular miRNome of human cerebral microvascular endothelial cells in a bystander fashion. Subsequent target prediction and pathway enrichment analysis indicated that these microRNAs and their corresponding target genes are involved in pathways associated with blood-brain barrier dysfunction such as "Adherens junction" and "Tight junction". Additionally, several miRNA-mRNA pairs were also found to be involved in cellular signaling pathways related to cytokine production, for instance, "Jak-STAT signaling pathway", "Chemokine signaling pathway", "IL-17 signaling pathway", "NF-κB signaling pathway", and "Viral protein interaction with cytokine and cytokine receptor". The dysregulated production of inflammatory cytokines is reported to compromise BBB permeability. This study is the first report to demonstrate that DENV-NS1-mediated miRNA perturbations are crucial in compromising endothelial barrier integrity. It also offers insights into potential therapeutic targets to mitigate DENV-NS1-induced vascular permeability and inflammation.
