Cortical organotypic slice cultures as a tool to analyze the neurovascular unit in hypoxia/ischemia and hypothermia-induced neuroprotection [PDF]

open access: yes, 2013
Neurons and glial cells of the central nervous system (CNS) communicate and work together to function and execute an array of complex tasks. In addition to them a third cell type which also works to keep the brain alive are the cerebral endothelial cells

An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

open access: yesAdvanced Science, EarlyView.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

Three distinct mechanisms generate oxygen free radicals in neurons and contribute to cell death during anoxia and reoxygenation

open access: yes, 2007
Ischemia is a major cause of brain damage, and patient management is complicated by the paradoxical injury that results from reoxygenation. We have now explored the generation of reactive oxygen species (ROS) in hippocampal and cortical neurons in ...

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Photoacoustic oxygenation imaging to identify ischemia/hypoxia injury and necrosis of intestine after acute intussusception: A comparative study with CDFI/CEUS

open access: yesPhotoacoustics
Acute intussusception is a pediatric abdominal emergency that requires immediate diagnosis and treatment. However, accurately identifying bowel necrosis non-invasively remains challenging with conventional sonography.

Regulation of hypoxia-inducible factor 1α and induction of vascular endothelial growth factor in a rat neonatal stroke model

open access: yesNeurobiology of Disease, 2003
Stroke is a devastating condition occurring in at least 1 in 4000 live births in the neonatal period. Since hypoxia-inducible factor (HIF)-1α can modulate ischemic injury via induction of target genes that may protect cells against ischemia, and is ...

Effect of Differently Polarized Human Macrophages on the SH-SY5Y Cells Damaged by Ischemia and Hypoxia In Vitro

open access: yesJournal of Immunology Research, 2023
Macrophages are the major cells of innate immunity with a wide range of biological effects due to their great plasticity and heterogeneity. Macrophages play a key role in neuroregeneration following nervous tissue injury.

Gasdermin D‐Mediated Release of IL‐33 Results in Fetal Brain Developmental Abnormalities During Maternal Colitis

open access: yesAdvanced Science, EarlyView.
Under colitis, Gsdmd mediates the release of IL‐33 from the epithelium of pregnant mice. IL‐33 can cross the placenta and enhance the proliferative capacity of neural stem cells, ultimately resulting in behavioral deficits in the offspring. Excessive pyroptosis in the colonic epithelium also triggers the translocation of LPS, which in turn increases ...

The GluN3A Subunit Exerts a Neuroprotective Effect in Brain Ischemia and the Hypoxia Process

open access: yesASN Neuro, 2013
NMDARs ( N -methyl-d-aspartate receptors) mediate the predominantly excitatory neurotransmission in the CNS (central nervous system). Excessive release of glutamate and overactivation of NMDARs during brain ischemia and the hypoxia process are causally ...

Preconditioning triggered by carbon monoxide (CO) provides neuronal protection following perinatal hypoxia-ischemia.

open access: yesPLoS ONE, 2012
Perinatal hypoxia-ischemia is a major cause of acute mortality in newborns and cognitive and motor impairments in children. Cerebral hypoxia-ischemia leads to excitotoxicity and necrotic and apoptotic cell death, in which mitochondria play a major role ...
