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

Orexin-A alleviates astrocytic apoptosis and inflammation via Inhibiting OX1R-mediated NF- κB and MAPK signaling pathways in cerebral ischemia/reperfusion injury
Biochim Biophys Acta Mol Basis Dis. 2021 Aug 3:166230. doi: 10.1016/j.bbadis.2021.166230. Online ahead of print.ABSTRACTOrexin-A (OXA) is a neuropeptide with neuroprotective effect by reducing cerebral ischemia/reperfusion injury (CIRI). Inflammation and apoptosis mediated by astrocyte activation are the key pathological mechanisms for CIRI. We thus attempted to confirm neuroprotective effects of OXA on astrocytic inflammation and apoptosis in CIRI and clarify the relative mechanisms. A middle cerebral artery occlusion and reperfusion (MCAO/R) rat model and U251 glioma cells model subjected to oxygen glucose deprivation an...

Total Glycosides of Cistanche deserticola Promote Neurological Function Recovery by Inducing Neurovascular Regeneration via Nrf-2/Keap-1 Pathway in MCAO/R Rats
ConclusionTGs are the main active components of C. deserticola against MCAO/R-induced cerebral injury, and protection is mainly via the Nrf-2/Keap-1 pathway.

Treadmill exercise improves neurological function by inhibiting autophagy and the binding of HMGB1 to Beclin1 in MCAO juvenile rats
Publication date: Available online 8 January 2020Source: Life SciencesAuthor(s): Guoyuan Pan, Lingqin Jin, Weimin Shen, Jieqiong Zhang, Juanjuan Pan, Jingyan Cheng, Qingfeng Xie, Quan Hu, Shamin Wu, Hongmei Zhang, Xiang ChenAbstractAimsTreadmill exercise is a beneficial treatment following childhood stroke. Thus, studies focusing on the neuroprotective mechanism of exercise training during postischemic treatment in children with ischemic stroke are urgently needed. We evaluated the effects of treadmill exercise on autophagy after cerebral ischemia in young rats.Main methodsRats (23–25 days old) underwent cerebral ische...

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]

Orally Administered Crocin Protects Against Cerebral Ischemia/Reperfusion Injury Through the Metabolic Transformation of Crocetin by Gut Microbiota
Conclusion Collectively, pharmacokinetic and pharmacodynamic association studies provide evidence that the gut microbiota plays a vital role in the fate of crocin and crocetin in the gastrointestinal tract. In addition, the cross-interaction between gut microbiota and crocin might mediate the activation of the cerebral-protective effect of orally administered crocin. Ethics Statement This study was carried out in accordance with the recommendations of ‘Institutional Animal Research Committee guidelines, Animal Ethics Committee of China Pharmaceutical University.’ The protocol was approved by the ‘An...

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...
