Establishment and Evaluation of a Monkey Acute Cerebral Ischemia Model [PDF]

open access: yesClinics, 2020
OBJECTIVES: Cerebral ischemia seriously threatens human health and is characterized by high rates of incidence, disability and death. Developing an ideal animal model of cerebral ischemia that reflects the human clinical features is critical for ...

Alterations in CD200-CD200R1 System during EAE Already Manifest at Presymptomatic Stages

open access: yesFrontiers in Cellular Neuroscience, 2017
In the brain of patients with multiple sclerosis, activated microglia/macrophages appear in active lesions and in normal appearing white matter. However, whether they play a beneficial or a detrimental role in the development of the pathology remains a ...

AG490 protects cerebral ischemia/reperfusion injury via inhibiting the JAK2/3 signaling pathway

open access: yesBrain and Behavior, 2021
Background Cerebral ischemia/reperfusion injury is a severe problem in patients with brain ischemia. Brain injury caused by the immune response is important in the pathogenesis of cerebral ischemia/reperfusion injury and immune pathways.

Nrf2 Regulates Oxidative Stress and Its Role in Cerebral Ischemic Stroke

open access: yesAntioxidants, 2022
Cerebral ischemic stroke is characterized by acute ischemia in a certain part of the brain, which leads to brain cells necrosis, apoptosis, ferroptosis, pyroptosis, etc.

Enlarged infarct volume and loss of BDNF mRNA induction following brain ischemia in mice lacking FGF-2 [PDF]

open access: yes, 2006
FGF-2, a potent multifunctional and neurotrophic growth factor, is widely expressed in the brain and upregulated in cerebral ischemia. Previous studies have shown that intraventricularly or systemically administered FGF-2 reduces the size of cerebral ...

Adenosine A2A receptor agonist polydeoxyribonucleotide ameliorates short-term memory impairment by suppressing cerebral ischemia-induced inflammation via MAPK pathway.

open access: yesPLoS ONE, 2021
Cerebral ischemia causes tissue death owing to occlusion of the cerebral blood vessels, and cerebral ischemia activates mitogen-activated protein kinase (MAPK) and induces secretion of pro-inflammatory cytokines.

Early MEK1/2 inhibition after global cerebral ischemia in rats reduces brain damage and improves outcome by preventing delayed vasoconstrictor receptor upregulation. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Global cerebral ischemia following cardiac arrest is associated with increased cerebral vasoconstriction and decreased cerebral blood flow, contributing to delayed neuronal cell death and neurological detriments in affected patients.

Exercise preconditioning exhibits neuroprotective effects on hippocampal CA1 neuronal damage after cerebral ischemia

open access: yesNeural Regeneration Research, 2015
Recent evidence has suggested the neuroprotective effects of physical exercise on cerebral ischemic injury. However, the role of physical exercise in cerebral ischemia-induced hippocampal damage remains controversial.

Function of BID - a molecule of the bcl-2 family - in ischemic cell death in the brain [PDF]

open access: yes, 2002
Mitochondrial mechanisms, particularly the release of cytochrome c, play a role in the death of nerve and glial cells in cerebral ischemia. We have currently investigated whether BID, a proapoptotic molecule of the bcl-2 family and promoter of the ...
