Evidence that enolase-phosphatase 1 exacerbates early cerebral ischemia injury and blood-brain barrier breakdown by enhancing extracellular matrix destruction and inhibiting the interaction between ADI1 and MT1-MMP
In this study, we systematically provide mechanistic insights into the regulation of ENOPH1 in blood-brain barrier (BBB) dysfuction induced by early ischemia. ENOPH1 knockout mice (ENOPH1 KO) and wild type (WT) mice were exposed to transient middle cerebral artery occlusion (tMCAO) for 90 min followed by 3 h of reperfusion in vivo, and brain microvascular endothelial cell lines (bEnd.3 cells) were exposed to oxygen-glucose deprivation (OGD) in vitro. BEnd.3 cells were transfected with ENOPH1 shRNA to knockdown ENOPH1 expression. Brain ischemic damage and nerve function was assessed with 2, 3, 5-triphenyltetrazolium chlorid...

Beta-Boswellic Acid Protects Against Cerebral Ischemia/Reperfusion Injury via the Protein Kinase C Epsilon/Nuclear Factor Erythroid 2-like 2/Heme Oxygenase-1 Pathway
This study demonstrates that β-BA exerts neuroprotective effects against cerebral I/R via the activation of the PRKCE/NFE2L2/HMOX1 pathway and is a potentia l therapeutic candidate for ischemic stroke.Graphical abstract

Ropinirole induces neuroprotection following reperfusion-promoted mitochondrial dysfunction after focal cerebral ischemia in Wistar rats.
In conclusion, these results demonstrate that Ropinirole treatment is beneficial in preserving the mitochondrial functions that are altered in cerebral ischemic injury and thus can help in defining better therapies. PMID: 31816341 [PubMed - as supplied by publisher]

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...
