Podoplanin neutralization reduces thrombo-inflammation in experimental ischemic stroke by inhibiting interferon/caspase-1/GSDMD in microglia.
Article in Annals of translational medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Background: Cerebral ischemia/reperfusion (I/R) injury involves the interaction between thrombosis and inflammatory pathways. The aim of this study was to explore the therapeutic effect of podoplanin neutralizing antibody (α-PDPN, clone 8.1.1) on I/R-induced thrombo-inflammation in a mouse model of ischemic stroke. Methods: Male C57BL/6 mice (weight: 22-25 g, aged 6-8 weeks, n=114) were subjected to transient middle cerebral artery occlusion (MCAO) and administered intracerebroventricular injection of α-PDPN (29 µg). Stroke outcomes and microvascular thromboses were examined by immunohistochemistry (IHC) and western blot analysis. In vitro, microglia BV2 cells were pre-treated with α-PDPN and then subjected to oxygen-glucose deprivation/reoxygenation (OGD/R) insult. The microglia culture medium (MCM) was co-cultured with vascular endothelial b.End3 cells. The MCM-induced bEnd.3 cells dysfunction were examined by western blot assays and IHC. Results: Blocking PDPN decreased the infarct size and ameliorated neurological deficit after MCAO without enhancing the risk of intracerebral hemorrhage. In addition, α-PDPN treatment significantly alleviated thrombus formation in the cerebral microvasculature. Furthermore, treatment with α-PDPN attenuated I/R-induced caspase-1 and gasdermin D expression Conclusions: Blocking PDPN can alleviate thrombo-inflammation in acute ischemic stroke by inhibiting caspase-1 expression in microglia, and indirectly reduce endothelial cell dysfunction. These data indicated the beneficial effects of blocking podoplanin during stroke in mice.
