Nrf2 activator peptide protects the brain from cerebral vascular dysfunction in alcohol ingestion.
Article in JCI insight, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Oxidative signaling is a central mechanism in alcohol-induced injury and has strong implications for blood-brain barrier (BBB) dysregulation and neuroinflammation. Here, by targeting oxidative signaling, we hypothesized an innovative approach to develop a clinically relevant therapeutic strategy for alleviating alcohol-mediated neurovascular damage. To accomplish this, we enhanced the endogenous activity of nuclear factor E2-related factor 2 (Nrf2) by treatment with a Nrf2 activator III TAT peptide (Nrf2 peptide [NP]) and investigated the neuroprotective role of Nrf2 in promoting antioxidant defense properties and reducing BBB damage and transmigration of leukocytes to the brain following alcohol ingestion. We administered the NP subcutaneously to alcohol-ingested mice and evaluated its therapeutic potential in alleviating alcohol-associated neurovascular impairments. We compared the results with those seen in animals treated with control peptide (random sequence with TAT). The studies showed that the NP treatment preserved the oxidant-antioxidant balance, downregulated ICAM-1 and its receptors, and mitigated BBB damage and leukocyte infiltration into the brain. We validated the effect of the NP in Nrf2-knockout (Nrf2-/-) mice. Thus, this study demonstrates that NP exerts neurovascular protective effects by regulating the oxidant-antioxidant balance, reducing oxidative stress-induced BBB disruption, and limiting transmigration of immune cells to the brain in a mouse model of alcohol ingestion.
