Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties

open access: yesAdvanced Science, EarlyView.
Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...

Síndrome de isquemia ocular: manifestaciones clínicas, diagnóstico y evolución tras el tratamiento

open access: yesRevista de la Facultad de Ciencias Médicas de Córdoba, 2019
Ocular ischemia syndrome is caused by ocular chronic hypoperfusion due to stenosis or occlusion of the ipsilateral common or internal carotid artery. We present the case of a 58-year-old male with recurrent unilateral amaurosis fugax, ophthalmological ...

Meta-analysis of genome-wide association studies from the CHARGE consortium identifies common variants associated with carotid intima media thickness and plaque [PDF]

open access: yes, 2011
Carotid intima media thickness (cIMT) and plaque determined by ultrasonography are established measures of subclinical atherosclerosis that each predicts future cardiovascular disease events.

Astrocytic LMP2 Coordinates NF‐κB and TGF‐β1/Smad3 Signaling to Drive Neuroinflammation after Cerebral Ischemia/Reperfusion

open access: yesAdvanced Science, EarlyView.
ABSTRACT Astrocyte reactivity critically shapes neuroinflammatory outcomes after ischemic stroke, yet the upstream regulators governing astrocyte state transitions remain incompletely defined. Here, we identify the immunoproteasome subunit low molecular weight protein 2 (LMP2) as an important modulator of astrocyte functional remodeling following ...

Endovascular treatment for chronic tandem occlusion of internal carotid artery: a case report

open access: yesThe Egyptian Journal of Neurology, Psychiatry and Neurosurgery
Background Occlusion of the internal carotid artery can lead to ischemic stroke. Currently, first-line treatment options for ischemic stroke include antiplatelet agents, lipid-regulating drugs, plaque-stabilizing medications, and comprehensive management

Extracellular CIRP Dysregulates Microglial Efferocytosis in Acute Ischemic Stroke via the TLR4/miR‐155/MafB Axis

open access: yesAdvanced Science, EarlyView.
eCIRP released in the stroke brain binds to TLR4 expressed on microglia to induce miR‐155, which suppresses MafB, decreases MerTK and downstream signaling to impair efferocytosis of apoptotic neurons, worsening the acute stroke outcomes. Inhibition of eCIRP‐TLR4 interaction with small peptide C23 attenuates eCIRP‐induced microglial efferocytic ...

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.

Spontaneous carotid artery dissection-associated medial changes in a selected autopsy population [PDF]

open access: yes, 2008
Spontaneous carotid artery dissection (SCAD) is a major cause of stroke in young adults, yet its pathogenesis remains unclear. Hereditary connective tissue diseases, hormonal influences, sympathomimetic drugs or upper respiratory tract infections may ...
