Exercise pretreatment alleviates neuroinflammation and oxidative stress by TFEB-mediated autophagic flux in mice with ischemic stroke
CONCLUSIONS: Exercise pretreatment has the potential to improve the prognosis of ischemic stroke patients, and it can exert neuroprotective effects in ischemic stroke by inhibiting neuroinflammation and oxidative stress, which might be due to the TFEB-mediated autophagic flux. And targeting autophagic flux may be promising strategies for the treatment of ischemic stroke.PMID:36914085 | DOI:10.1016/j.expneurol.2023.114380

Isoflurane and Netrin-1 combination therapy enhances angiogenesis and neurological recovery by improving the expression of HIF-1 α-Netrin-1-UNC5B/VEGF cascade to attenuate cerebral ischemia injury
In conclusion, our results suggested that ISO combined with NT-1 could promote angiogenesis, recover long-term neurobehavioral function, and attenuate cerebral ischemia injury by activating the HIF-1α-Netrin-1-UNC5B/VEGF cascade.PMID:35247371 | DOI:10.1016/j.expneurol.2022.114028

Resveratrol reduces cerebral edema through inhibition of de novo SUR1 expression induced after focal ischemia.
Abstract Cerebral edema is a clinical problem that frequently follows ischemic infarcts. Sulfonylurea receptor 1 (SUR1) is an inducible protein that can form a heteromultimeric complex with aquaporin 4 (AQP4) that mediate the ion/water transport involved in brain tissue swelling. Transcription of the Abcc8 gene coding for SUR1 depends on the activity of transcriptional factor SP1, which is modulated by the cellular redox environment. Since oxidative stress is implicated in the induced neuronal damage in ischemia and edema formation, the present study aimed to evaluate if the antioxidant resveratrol (RSV) prevents ...

Bone marrow mesenchymal stem cell-derived exosomes attenuate cerebral ischemia-reperfusion injury-induced neuroinflammation and pyroptosis by modulating microglia M1/M2 phenotypes
CONCLUSION: BMSC-Exos could ameliorate cerebral I/R injury via suppression of NLRP3 inflammasome-mediated inflammation and pyroptosis by modulating microglial polarization.PMID:33741350 | DOI:10.1016/j.expneurol.2021.113700

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...
