N-Myc Downstream-Regulated Gene 2 (Ndrg2) Is Involved in Ischemia–Hypoxia-Induced Astrocyte Apoptosis: a Novel Target for Stroke Therapy
In conclusion, NDRG2 is involved in astrocyte apoptosis following ischemic–hypoxic injury, and inhibiting NDRG2 expression significantly reduces ROS production and astrocyte apoptosis. These findings provide insight into the role of NDRG2 in ischemic–hypoxic injury and provide potential targets for future clinical therapies for stroke.

DAPK1 Signaling Pathways in Stroke: from Mechanisms to Therapies
AbstractDeath-associated protein kinase 1 (DAPK1), a Ca2+/calmodulin (CaM)-dependent serine/threonine protein kinase, plays important roles in diverse apoptosis pathways not only in tumor suppression but also in neuronal cell death. The requirement of DAPK1 catalytic activity for its proposed cell functions and the elevation of catalytic activity of DAPK1 in injured neurons in models of neurological diseases, such as ischemia and epilepsy, validate that DAPK1 can be taken as a potential therapeutic target in these diseases. Recent studies show that DAPK1-NR2B, DAPK1-DANGER, DAPK1-p53, and DAPK1-Tau are currently known path...

Dodecafluoropentane Improves Neurological Function Following Anterior Ischemic Stroke
This study investigated shortened dosage schedules of DDFPe in nonstandard posterior (NSTND) strokes following occlusions of the posterior cerebral arteries. DDFPe given at shortened schedules of 30 or 60-min injection intervals will reduce neurological deficits, percent stroke volume (%SV), and serum glutamate levels in NSTND ischemic strokes. New Zealand White rabbits (N = 26) were randomly placed into three groups: A (n = 9) controls given saline injections every 60 min, B (n = 9) 2 % DDFPe given IV every 30 min, and C (n = 8) DDFPe every 60 min. Injections began 1 h after embolization. Groups were subdivid...

Canonical Wnt Pathway Maintains Blood-Brain Barrier Integrity upon Ischemic Stroke and Its Activation Ameliorates Tissue Plasminogen Activator Therapy
AbstractStroke induces blood-brain barrier (BBB) breakdown, which promotes complications like oedema and hemorrhagic transformation. Administration of recombinant tissue plasminogen activator (rtPA) within a therapeutic time window of 4.5  h after stroke onset constitutes the only existing treatment. Beyond this time window, rtPA worsens BBB breakdown. Canonical Wnt pathway induces BBB formation and maturation during ontogeny. We hypothesized that the pathway is required to maintain BBB functions after stroke; thus, its activation m ight improve rtPA therapy. Therefore, we first assessed pathway activity in the brain of m...

Cross-Talk Between Key Players in Patients with COVID-19 and Ischemic Stroke: A  Review on Neurobiological Insight of the Pandemic
AbstractThe global pandemic of novel coronavirus disease 2019 (COVID-19) has taken the entire human race by surprise and led to an unprecedented number of mortalities worldwide so far. Current clinical studies have interpreted that angiotensin-converting enzyme 2 (ACE2) is the host receptor for severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). In addition, ACE2 is the major component of the renin-angiotensin system. ACE2 deteriorates angiotensin II, a peptide that is responsible for the promotion of stroke. The downregulation of ACE2 further activates an immunological cascade. Thus, researchers need to explore ...

Remote but not Distant: a Review on Experimental Models and Clinical Trials in Remote Ischemic Conditioning as Potential Therapy in Ischemic Stroke
AbstractStroke is one of the main causes of neurological disability worldwide and the second cause of death in people over 65  years old, resulting in great economic and social burden. Ischemic stroke accounts for 85% of total cases, and the approved therapies are based on re-establishment of blood flow, and do not directly target brain parenchyma. Thus, novel therapies are urgently needed. In this review, limb remote isc hemic conditioning (RIC) is revised and discussed as a potential therapy against ischemic stroke. The review targets both (i) fundamental research based on experimental models and (ii) clinical research ...

SATB1/SLC7A11/HO-1 Axis Ameliorates Ferroptosis in Neuron Cells After Ischemic Stroke by Danhong Injection
AbstractNeuronal damage after ischemic stroke (IS) is frequently due to ferroptosis, contributing significantly to ischemic injury. However, the mechanism against ferroptosis in IS remained unclear. The aim of this study was to investigate the potential mechanism of Danhong injection (DHI) and the critical transcription factor SATB1 in preventing neuronal ferroptosis after ischemic stroke in vivo and in vitro. The results showed that DHI treatment significantly reduced the infarct area and associated damage in the brains of the pMCAO mice, and enhanced the viability of OGD-injured neurons. And several characteristic indica...

Gadd45b Mediates Axonal Plasticity and Subsequent Functional Recovery After Experimental Stroke in Rats
Abstract Stroke causes devastating and irreversible losses of neurological function with subsequent slow and incomplete recovery of lost brain functions, because of the brain’s limited capacity for brain plasticity. Growth arrest and DNA-damage-inducible protein 45 beta (Gadd45b) has recently been demonstrated as a candidate plasticity-related gene, making it an excellent candidate molecule that has therapeutic potential. Here, we examine whether in vivo blockage of Gadd45b affects axonal plasticity and subsequent functional recovery after focal brain infarction. Adult male Sprague-Dawley rats were subjected to ...

Elevated Serum Levels of CXC Chemokine Ligand-12 Are Associated with Unfavorable Functional Outcome and Mortality at 6-Month Follow-up in Chinese Patients with Acute Ischemic Stroke
Abstract The aim of this study was to examine whether the circulating CXC chemokine ligand-12 (CXCL12) level can predict a 6-month outcome in Chinese patients with acute ischemic stroke (AIS). In a prospective study, CXCL12 levels were measured on admission in the serum of 304 consecutive patients with AIS. The prognostic value of CXCL12 to predict the functional outcome and mortality within 1 year was compared with the National Institutes of Health Stroke Scale score and with other known outcome predictors. A receiver operating characteristic (ROC) curve was used to evaluate the accuracy of serum CXCL12 in predi...

Low Serum Levels of Brain-Derived Neurotrophic Factor Were Associated with Poor Short-Term Functional Outcome and Mortality in Acute Ischemic Stroke
In this study, 204 patients were included. Patients with poor outcomes and non-survivors had significantly lower BDNF levels on admission (P <  0.0001 all). Multivariate logistic regression analysis adjusted for common risk factors showed that BDNF levels in the lowest interquartile (≤1st 9.2 ng/ml) was an independent predictor of functional outcome (odds ratios [OR] = 3.75; 95 % confidence interval [CI], 2.43–8.12) and mortality (OR = 4.04; 95 % CI, 2.07–9.14). The area under the receiver operating characteristic curve of BDNF was 0.77 (95 % CI, 0.70–0.84) for functional outcome and 0.79 (95 % CI, 0....

TAT-PEP Enhanced Neurobehavioral Functional Recovery by Facilitating Axonal Regeneration and Corticospinal Tract Projection After Stroke
AbstractPaired immunoglobulin-like receptor B (PirB) has been identified as a new receptor for myelin-associated inhibitory (MAI) proteins, which may play important role in axonal regeneration and corticospinal tract (CST) projection associated with neurobehavioral function recovery after stroke. Here, we found that the expression of PirB was increased in the cortical penumbra from 1 to 28  days after transient focal cerebral ischemic reperfusion of rats. Then, transactivator of transcription-PirB extracellular peptide (TAT-PEP) was generated that might block the interactions between MAIs and PirB. The results showed that...

Evidence that NF- κB and MAPK Signaling Promotes NLRP Inflammasome Activation in Neurons Following Ischemic Stroke
In this study, we provide evidence that activation of either the NF-κB and MAPK signaling pathways was partly responsible for inducing the expression and activation of NLRP1 and NLRP3 inflammasome proteins and that these effects can be attenuated using pharmacological inhibitors of these two pathways in neurons and brain tissue under in vitro and in vivo ischemic conditions, respectively. Moreover, these findings provided supporting evidence that treatment with intravenous immunoglobulin (IVIg) preparation can reduce activation of the NF-κB and MAPK signaling pathways resulting in decreased expression and activation of N...
