Irisin Peptide Protects Brain Against Ischemic Injury Through Reducing Apoptosis and Enhancing BDNF in a Rodent Model of Stroke.
Abstract Evidence has shown therapeutic potential of irisin in cerebral stroke. The present study aimed to assess the effects of recombinant irisin on the infarct size, neurological outcomes, blood-brain barrier (BBB) permeability, apoptosis and brain-derived neurotrophic factor (BDNF) expression in a mouse model of stroke. Transient focal cerebral ischemia was established by middle cerebral artery occlusion (MCAO) for 45 min and followed reperfusion for 23 h in mice. Recombinant irisin was administrated at doses of 0.1, 0.5, 2.5, 7.5, and 15 µg/kg, intracerebroventricularly (ICV), on the MCAO beginning. Neuro...

Transcription Factor HEY1 Improves Brain Vascular Endothelial Cell Function and Alleviates Ischemic Stroke by Upregulating NOTCH3
Neurochem Res. 2022 Mar 22. doi: 10.1007/s11064-022-03544-w. Online ahead of print.ABSTRACTTo investigate the function of hairy/enhancer-of-split related with YRPW motif protein 1 (HEY1) and Notch receptor 3 (NOTCH3) in ischemic stroke. Stroke models were established by middle cerebral artery occlusion (MCAO) and oxygen glucose deprivation (OGD) in rats and rat brain microvascular endothelial cells (BMVECs), respectively. Neurological deficit evaluation and 2,3,5-triphenyltetrazolium chloride staining were used to assess cerebral injury. The expression of HEY1 and NOTCH3 was manipulated using gain and loss of function appr...

Nitrogen-doped carbon nanocages and human umbilical cord mesenchymal stem cells cooperatively inhibit neuroinflammation and protect against ischemic stroke
This study aimed to explore the synergistic effects of nitrogen-doped carbon nanocages (NCNCs) and human umbilical cord mesenchymal stem cells (HUC-MSCs) on ischemic stroke and investigate the potential underlying mechanisms.Main methodsThe properties of NCNCs were analyzed by transmission electron microscopy, and the markers of HUC-MSCs were detected by flow cytometry. The cell toxicity of NCNCs was evaluated by MTT. Mice were induced cerebral infarction by transient middle cerebral artery occlusion (MCAO). NCNCs or HUC-MSCs or HUC-MSCs-NCNCs were intravenously injected thirty minutes after reperfusion. The infarct volume...

Astragaloside IV alleviates neuronal ferroptosis in ischemic stroke by regulating fat mass and obesity ‐associated—N6‐methyladenosine—acyl‐CoA synthetase long‐chain family member 4 axis
Ischemic stroke (IS) is a detrimental neurological disease with limited treatments options. Astragaloside IV (As-IV) was a promising bioactive constituent in the treatment of IS. In our study, As-IV promoted the transcription of fat mass and obesity-associated (Fto) by upregulating activating transcription factor 3(Atf3), resulting in a decrease of long-chain acyl-CoA synthetase-4 (Acsl4) N6-methyladenosine (m6A) levels, thus improving neuronal injury in IS by inhibiting ferroptosis. These findings provided a better understanding of the molecular mechanisms underlying the neuroprotective effects of As-IV and led to novel t...

Integrated 16S rRNA Gene Sequencing and LC-MS Analysis Revealed the Interplay Between Gut Microbiota and Plasma Metabolites in Rats With Ischemic Stroke
This study aimed to reveal the specific asso-ciation between the microbiota and the metabolites in IS using integrated 16S rRNA gene sequencing and liquid chromatography-mass spectrometry (LC-MS) analysis. Male Sprague Dawley (SD) rats were divided into three groups: normal group (n = 8, Normal), model group (n = 9, IS), and sham-operated group (n = 8, Sham). Rats in the IS group were induced by middle cerebral artery occlusion (MCAO), and rats in the Sham group received an initial anesthesia and neck incision only. A neurological function test and 2,3,5-triphenyltetrazolium chloride (TTC) staining were used to...

Neurophysiological Analysis of Intermanual Transfer in Motor Learning
In this study, MEPs were induced during the subject’s imaged kinesthetic MI. This involves recalling muscle contraction based on a muscle sensory image and was reported to indicate the activity of brain regions similar to those involved in actual muscle contraction (Ruby and Decety, 2001). In the transfer training group, the muscle sensory image evaluation correlated to the actual task execution with the right hand. As a result, it was easy to recall the kinesthetic MI for the training task, thus affecting MI of the non-trained limbs so that MEP changes occurred in the left hand’s MI. In addition, brain exc...

Inhibition of Nkcc1 promotes axonal growth and motor recovery in ischemic rats
In conclusion, bumetanide promoted post-stroke axonal sprouting together accompanied by an improved behavioral outcome possibly through restoring and maintaining neuronal chloride homeostasis and creating a recovery-promoting microenvironment by overcoming the axonal growth inhibition encountered after cerebral ischemia in rats.

Interleukin-33 Protects Ischemic Brain Injury by Regulating Specific Microglial Activities
Publication date: 10 August 2018 Source:Neuroscience, Volume 385 Author(s): Qianping Luo, Yong Fan, Lili Lin, Jingjing Wei, Zuanfang Li, Yongkun Li, Susumu Nakae, Wei Lin, Qi Chen Interleukin-33 (IL-33), a novel member of the IL-1 family, expressed in many tissue and cell types, is involved in inflammation and immune functions. Previous studies suggest that IL-33 may play a role in ischemic stroke. Here, we evaluated the effect of IL-33 in cerebral ischemia–reperfusion-induced injury and investigated its underlying mechanism. Our data indicated that IL-33 deficiency exacerbated the neurological dysfunction caused by cer...

mfat ‐1 transgene protects cultured adult neural stem cells against cobalt chloride‐mediated hypoxic injury by activating Nrf2/ARE pathways
Abstract Ischemic stroke is a devastating neurological disorder and one of the leading causes of death and serious disability in adults. Adult neural stem cell (NSC) replacement therapy is a promising treatment for both structural and functional neurological recovery. However, for the treatment to work, adult NSCs must be protected against hypoxic‐ischemic damage in the ischemic penumbra. In the present study, we aimed to investigate the neuroprotective effects of the mfat‐1 transgene on cobalt chloride (CoCl2)‐induced hypoxic‐ischemic injury in cultured adult NSCs as well as its underlying mechanisms. The results ...

Inhibition of Calcium/Calmodulin-Dependent Protein Kinase II α Suppresses Oxidative Stress in Cerebral Ischemic Rats Through Targeting Glucose 6-Phosphate Dehydrogenase.
Inhibition of Calcium/Calmodulin-Dependent Protein Kinase IIα Suppresses Oxidative Stress in Cerebral Ischemic Rats Through Targeting Glucose 6-Phosphate Dehydrogenase. Neurochem Res. 2019 Mar 27;: Authors: Wei Y, Wang R, Teng J Abstract Ischemic stroke is a leading cause of mortality and morbidity worldwide, and oxidative stress plays a significant role in the ischemia stage and reperfusion stage. Previous studies have indicated that both calcium/calmodulin-dependent protein kinase II (CaMKII) and glucose 6-phosphate dehydrogenase (G6PD) are involved in the oxidative stress. Thus, the aim of this st...
