Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Measuring Blood-brain-barrier Permeability Using Evans Blue in Mice

open access: yesBio-Protocol, 2015
The blood–brain barrier (BBB) is a highly selective permeability barrier that separates the circulating blood from the brain extracellular fluid in the central nervous system.

Predicting drug penetration across the blood-brain barrier: comparison of different stationary phases for immobilized artificial membrane liquid chromatography [PDF]

open access: yes, 2014
Several in vitro methods have been tested for their ability to predict drug penetration across the blood-brain barrier into the central nervous system. In this article, the performance of three stationary phases for immobilized artificial membrane (IAM ...

Review: Dystroglycan in the Nervous System [PDF]

open access: yes, 2007
Dystroglycan is part of a large complex of proteins, the dystrophin-glycoprotein complex, which has been implicated in the pathogenesis of muscular dystrophies for a long time.

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

open access: yesFEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

Barrier mechanisms in the Drosophila blood-brain barrier

open access: yesFrontiers in Neuroscience, 2014
The invertebrate blood-brain barrier field is growing at a rapid pace and, in recent years, studies have shown a physiologic and molecular complexity that has begun to rival its vertebrate counterpart. Novel mechanisms of paracellular barrier maintenance

NR4A1 Exerts Pro‐Tumor Role in Glioblastoma via Inducing xCT/GPX4‐Regulated Ferroptosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose This study investigates NR4A1's paradoxical roles in glioblastoma (GBM) progression, focusing on its mechanistic link to ferroptosis regulation. We aimed to resolve conflicting reports of NR4A1 as both an oncogene and a tumor suppressor by defining its transcriptional control over xCT/GPX4‐mediated iron homeostasis and its clinical ...

Association between impaired dynamic cerebral autoregulation and BBB disruption in reversible cerebral vasoconstriction syndrome

open access: yesThe Journal of Headache and Pain, 2023
Background Half of the sufferers of reversible cerebral vasoconstriction syndrome (RCVS) exhibit imaging-proven blood-brain barrier disruption. The pathogenesis of blood-brain barrier disruption in RCVS remains unclear and mechanism-specific intervention

Computational and in vitro studies of blast-induced blood-brain barrier disruption

open access: yes, 2015
There is growing concern that blast-exposed individuals are at risk of developing neurological disorders later in life. Therefore, it is important to understand the dynamic properties of blast forces on brain cells, including the endothelial cells that ...

Mechanisms of long-term cognitive dysfunction of sepsis: from blood-borne leukocytes to glial cells [PDF]

open access: yes, 2015
Several mechanisms are associated with brain dysfunction during sepsis; one of the most important are activation of microglia and astrocytes. Activation of glial cells induces changes in permeability of the blood-brain barrier, secretion of inflammatory ...
