Endothelial ferroptosis in blood-brain barrier dysfunction and neuroinflammation: mechanisms and immune-vascular crosstalk.
Review in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Ferroptosis is an iron-dependent form of regulated cell death driven by phospholipid peroxidation. In the central nervous system (CNS), most ferroptosis research has focused on neurons and glial cells, whereas the vulnerability of brain microvascular endothelial cells (BMECs) and its consequences for blood-brain barrier (BBB) integrity remain less clearly defined. Because BMECs form the vascular interface between the circulation and the brain parenchyma, ferroptotic injury in this cell population may represent an immunovascular mechanism through which endothelial redox stress is translated into barrier dysfunction and neuroinflammatory amplification. In this review, we summarize molecular pathways that may promote or restrain BMEC ferroptosis, including iron handling, antioxidant defense mediated by the solute carrier family 7 member 11 (SLC7A11)-glutathione peroxidase 4 (GPX4) axis and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, lipid peroxidation, and junctional remodeling. We then discuss how ferroptosis-associated endothelial injury may contribute to BBB leakage, damage-associated molecular pattern release, innate immune sensing, leukocyte recruitment, glial activation, and self-amplifying inflammatory feedback at the neurovascular interface. We organize the available literature according to the strength and cellular specificity of evidence, separating BMEC-specific findings, BBB-focused
