The NG2-glia is a potential target to maintain the integrity of neurovascular unit after acute ischemic stroke
Neurobiol Dis. 2023 Mar 13:106076. doi: 10.1016/j.nbd.2023.106076. Online ahead of print.ABSTRACTThe neurovascular unit (NVU) plays a critical role in health and disease. In the current review, we discuss the critical role of a class of neural/glial antigen 2 (NG2)-expressing glial cells (NG2-glia) in regulating NVU after acute ischemic stroke (AIS). We first introduce the role of NG2-glia in the formation of NVU during development as well as aging-induced damage to NVU and accompanying NG2-glia change. We then discuss the reciprocal interactions between NG2-glia and the other component cells of NVU, emphasizing the factor...

From Hair to the Brain: The Short-Term Therapeutic Potential of Human Hair Follicle-Derived Stem Cells and Their Conditioned Medium in a Rat Model of Stroke
We describe here for the first time the therapeutic potential of human hair follicle-derived stem cells (hHFSCs) and their conditioned medium (CM) in a rat model of IS. Furthermore, we hypothesized that a combination of cell therapy with repeated CM administration might enhance the restorative efficiency of this approach compared to each treatment alone. Middle cerebral artery occlusion was performed for 30  min to induce IS. Immediately after reperfusion, hHFSCs were transplanted through the intra-arterial route and/or hHFSC-CM administered intranasally. The neurological outcomes, short-term spatial working memory, and i...

Cryptotanshinone Attenuates Oxygen-Glucose Deprivation/ Recovery-Induced Injury in an in vitro Model of Neurovascular Unit
Conclusions Despite the above limitations, we indicate that the protective mechanism of CTs against OGD/R damage might exert via inhibiting neuron apoptosis and attenuating BBB disruption. Furthermore, we also clarified that CTs inhibited neuronal apoptosis possibly by blocking the activation of MAPK signaling pathways, and CTs alleviating BBB disruption may associated with the regulation of TJPs and MMP-9 in our experiment. Accordingly, CTs will represent a novel and potent candidate for the treatment of CIRI in the future. Ethics Statement This study was carried out in accordance with the recommendations of China�...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Cholestyramine resin administration alleviated cerebral ischemic injury in obese mice by improving gut dysbiosis and modulating the bile acid profile
In conclusion, Obesity induces gut dysbiosis, worsens stroke outcomes, and perturbs the BA profile. The dysbiotic microbiome is an important linkage between obesity and stroke. CR confers metabolic benefits and neuroprotective effects in obesity, perhaps by modulating gut microbial composition and BA metabolism.PMID:36179877 | DOI:10.1016/j.expneurol.2022.114234

Glycosaminoglycan scaffolding and neural progenitor cell transplantation promotes regenerative immunomodulation in the mouse ischemic brain
Exp Neurol. 2022 Jul 19:114177. doi: 10.1016/j.expneurol.2022.114177. Online ahead of print.ABSTRACTIschemic stroke is a leading cause of morbidity and mortality, with limited treatments that can facilitate brain regeneration. Neural progenitor cells (NPCs) hold promise for replacing tissue lost to stroke, and biomaterial approaches may improve their efficacy to overcome hurdles in clinical translation. The immune response and its role in stroke pathogenesis and regeneration may interplay with critical mechanisms of stem cell and biomaterial therapies. Cellular therapy can modulate the immune response to reduce toxic neuro...

The Clinical Characteristics of Acute Cerebrovascular Accidents Resulting from Ovarian Hyperstimulation Syndrome
Conclusion: The MCA and ICA are easily involved in stroke resulting from OHSS. The young age may be a risk factor for developing stroke secondary to OHSS. Once thromboembolism develops, administering appropriate therapy is crucial.Eur Neurol 2017;77:221-230

An Updated Review of Mitochondrial Transplantation as a Potential Therapeutic Strategy Against Cerebral Ischemia and Cerebral Ischemia/Reperfusion Injury
AbstractRegardless of the progress made in the pathogenesis of ischemic stroke, it remains a leading cause of adult disability and death. To date, the most effective treatment for ischemic stroke is the timely recanalization of the occluded artery. However, the short time window and reperfusion injury have greatly limited its application and efficacy. Mitochondrial dysfunction and ATP depletion have become regarded as being hallmarks of neuropathophysiology following ischemic stroke. Mitochondrial transplantation is a novel potential therapeutic intervention for ischemic stroke that has sparked widespread concern during th...

Grafted human neural stem cells enhance several steps of endogenous neurogenesis and improve behavioral recovery after middle cerebral artery occlusion in rats.
Abstract Neural stem/progenitor cells (NSPCs) in subventricular zone (SVZ) produce new striatal neurons during several months after stroke, which may contribute to recovery. Intracerebral grafts of NSPCs can exert beneficial effects after stroke through neuronal replacement, trophic actions, neuroprotection, and modulation of inflammation. Here we have explored whether human fetal striatum-derived NSPC-grafts influence striatal neurogenesis and promote recovery in stroke-damaged brain. T cell-deficient rats were subjected to 1h middle cerebral artery occlusion (MCAO). Human fetal NSPCs or vehicle were implanted in...

Bioluminescence imaging of transplanted human endothelial colony-forming cells in an ischemic mouse model.
The objectives of this study are to visualize the fate of infused human cord blood derived ECFCs via bioluminescence imaging (BLI) in an ischemic stroke mouse model and to determine the therapeutic effects of ECFC transplantation. ECFCs derived from human umbilical cord blood were infected with lentivirus carrying enhanced green fluorescent protein (eGFP) and firefly luciferase (Luc2) double fusion reporter gene. Labeled ECFCs were grafted into a photothrombotic ischemic stroke mouse model via intra-arterial injection though the left cardiac ventricle. The homing of infused cells and functional recovery of stroke mice were...

Thrombosis at the Site of Pulmonary Venous Anastomosis Following Lung Transplantation Presenting with Multiple, Bilateral, Supra- and Infra-Tentorial Ischemic Strokes in the Setting of a Known Patent Foramen Ovale (P4.355)
CONCLUSIONS: PFO-related stroke risk over time remains a controversial matter and so does its prevention by closure, as there is no current evidence-based data to justify this procedure except on anecdotal basis. LT patients may represent a subset population who could benefit from pre-operative PFO screening and closure, especially if they have a history of prior strokes.Disclosure: Dr. Yeung has nothing to disclose.
