Anfibatide Preserves Blood-Brain Barrier Integrity by Inhibiting TLR4/RhoA/ROCK Pathway After Cerebral Ischemia/Reperfusion Injury in Rat.
Article in Journal of molecular neuroscience : MN, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
The disruption of the blood-brain barrier (BBB) and the consequent brain edema are major contributors to the pathogenesis of cerebral ischemia/reperfusion injury. RhoA is generally thought to play a crucial role in the process of BBB disruption and participate in the signaling pathways emanating from TLR4. However, it remains unverified the regulatory role of TLR4 in the RhoA/ROCK pathway in cerebral I/R injury and its effects on the BBB as well. The present study probes into the protective effect of ANF on the BBB after cerebral I/R injury and the possible mechanisms. Focal cerebral ischemia was induced by 120 min of transient middle cerebral artery occlusion (MCAO). ANF (1, 2, 4 μg/kg) was achieved by intravenous injection after 120 min of MCAO followed by 1, 24, 48, and 72 h reperfusion. Evans blue extravasation, brain water content, RhoA activity, and the expressions of TLR4, ROCK1/2, p-MLC2, MMP-2/9, ZO-1, occludin, and claudin-5 protein in rat brain were evaluated 72 h after reperfusion. ANF could significantly reduce the Evans blue extravasation and water content in the ipsilateral hemisphere and obviously increase the occludin, claudin-5, and ZO-1 expression after cerebral I/R injury. Furthermore, cerebral I/R injury induced apparently increased expression of TLR4, RhoA-GTP, ROCK1/2, p-MLC2, and MMMP-2/9, which, however, could be remarkably alleviated by ANF intervention. Taken together, the TLR4/RhoA/ROCK signaling pathway is implicated in BBB breakdown after cerebral I/R injury, and ANF preserves BBB integrity, probably via inhibiting the TLR4/RhoA/ROCK signaling pathway.
