Development of bilateral dural arteriovenous fistulae following pial synangiosis for moyamoya syndrome: case report.

J Neurosurg Pediatr 2019 Apr 12:1-5. Epub 2019 Apr 12.

Departments of1Neurosurgery and.

Moyamoya syndrome predisposes patients to ischemic or hemorrhagic stroke due to progressive narrowing of intracranial vessels with subsequent small-vessel collateralization. Dural arteriovenous fistulae (DAVFs) are most commonly noted after venous sinus or cortical vein thrombosis and are believed to be primarily due to venous hypertension and elevated sinus pressures, although there is no known association with moyamoya syndrome, or with surgical treatment for moyamoya disease (MMD). The authors present the case of a 14-year-old girl with Down syndrome treated using pial synangiosis for MMD who subsequently was noted to have bilateral DAVFs. Read More

t-PA Suppresses the Immune Response and Aggravates Neurological Deficit in a Murine Model of Ischemic Stroke.

Front Immunol 2019 27;10:591. Epub 2019 Mar 27.

Molecular Neurotrauma and Haemostasis, Australian Centre for Blood Diseases, Monash University, Melbourne, VIC, Australia.

Acute ischemic stroke (AIS) is a potent trigger of immunosuppression, resulting in increased infection risk. While thrombolytic therapy with tissue-type plasminogen activator (t-PA) is still the only pharmacological treatment for AIS, plasmin, the effector protease, has been reported to suppress dendritic cells (DCs), known for their potent antigen-presenting capacity. Accordingly, in the major group of thrombolyzed AIS patients who fail to reanalyze (>60%), t-PA might trigger unintended and potentially harmful immunosuppressive consequences instead of beneficial reperfusion.

Myosin1f-mediated neutrophil migration contributes to acute neuroinflammation and brain injury after stroke in mice.

J Neuroinflammation 2019 Apr 10;16(1):77. Epub 2019 Apr 10.

Department of Neurosurgery, Stanford University School of Medicine, 1201 Welch Road, MSLS Building, Room P306, Stanford, CA, 94305, USA.

Background: During the acute stroke phase, neutrophils from the peripheral blood are first to arrive in the ischemic brain, which then attracts other immune cells that exacerbate neuroinflammation in the ischemic tissue. Myosin1f was reported to specifically mediate neutrophil migration in the peripheral tissues, but whether it plays a critical role in the neuroinflammatory response after ischemic stroke remains unknown. In this study, we aim to test the hypothesis that myosin1f-mediated neutrophil migration is critical in acute neuroinflammation induced by ischemic stroke. Read More

Uric acid treatment after stroke modulates the Krüppel-like factor 2-VEGF-A axis to protect brain endothelial cell functions: Impact of hypertension.

Biochem Pharmacol 2019 Apr 4;164:115-128. Epub 2019 Apr 4.

Departament de Farmacologia, de Terapèutica i de Toxicologia, Facultat de Medicina, Institut de Neurociències, Universitat Autònoma de Barcelona, Bellaterra, Spain. Electronic address:

Uric acid (UA) is a promising protective treatment in ischaemic stroke, but the precise molecular targets underlying its in vivo beneficial actions remain unclear. High concentrations of UA inhibit angiogenesis of cultured endothelial cells via Krüppel-like factor 2 (KLF)-induced downregulation of vascular endothelial growth factor (VEGF), a pro-angiogenic mediator that is able to increase blood-brain barrier (BBB) permeability in acute stroke. Here, we investigated whether UA treatment after ischaemic stroke protects brain endothelial cell functions and modulates the KLF2-VEGF-A axis. Read More

Inhibition of soluble epoxide hydrolase regulates monocyte/macrophage polarization and improves neurological outcome in a rat model of ischemic stroke.

Neuroreport 2019 Apr 3. Epub 2019 Apr 3.

Institute of Brain Science.

It is generally understood that continuing neuroinflammation after ischemic stroke can exacerbate the brain damage. During the inflammatory hematogenous recruitment process, the monocytes and macrophages are activated into proinflammatory M1 and anti-inflammatory M2 cell types. Inhibition of soluble epoxide hydrolase (sEH) activity has been reported to regulate monocytes/macrophages, and attenuates neuroinflammation. Read More

J Biol Regul Homeost Agents 2019 Mar-Apr,;33(2):375-384

The Second Internal Medicine-Neurology, The Third Affiliated Hospital of Qiqihar Medical University, Tiefeng District, Qiqihar City, Heilongjiang Province, China.

This study was aimed to investigate whether interferon (IFN)-induced protein 35 (IFI35) affects the signaling pathway of nuclear factor-kappa B (NF-κB) and to observe the effect of different expressions of IFI35 on the proliferation of endothelial cells and angiogenesis in rats with acute cerebral infarction. A suture method was adopted to prepare a mouse model of permanent middle cerebral artery occlusion (PMCAO). After the treatment of cerebral artery occlusion in 200 healthy male mice (weighting 20g-40g), 47 mice were selected and the double luciferase assay was used to identify different structural domains of IFI35; for the remaining 153 mice, RT-PCR and immunohistochemical assays were used to detect the mRNA expression of glioma-associated oncogene homolog 1 (Gli1), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and CD105 (endoglin).
