Cerebral ischemia is a multifactorial pathology characterized first by an acute injury, due to excitotoxicity, followed by a secondary brain injury that develops hours to days after ischemia. During ischemia, adenosine acts as an endogenous neuroprotectant. Few studies have investigated the role of A receptor in brain ischemia because of the low potency of adenosine for it and the few selective ligands developed so far. A receptors are scarcely but widely distributed in the brain on neurons, glial and endothelial cells and on hematopoietic cells, lymphocytes and neutrophils, where they exert mainly anti-inflammatory effects, inhibiting vascular adhesion and inflammatory cells migration. Aim of this work was to verify whether chronic administration of the A agonist, BAY60-6583 (0.1 mg/kg i.p., twice/day), starting 4 h after focal ischemia induced by transient (1 h) Middle Cerebral Artery occlusion (tMCAo) in the rat, was protective after the ischemic insult. BAY60-6583 improved the neurological deficit up to 7 days after tMCAo. Seven days after ischemia BAY60-6583 reduced significantly the ischemic brain damage in cortex and striatum, counteracted ischemia-induced neuronal death, reduced microglia activation and astrocytes alteration. Moreover, it decreased the expression of TNF-α and increased that of IL-10 in peripheral plasma. Two days after ischemia BAY60-6583 reduced blood cell infiltration in the ischemic cortex. The present study indicates that A receptors stimulation can attenuate the neuroinflammation that develops after ischemia, suggesting that A receptors may represent a new interesting pharmacological target to protect from degeneration after brain ischemia.

Interaction between miRNA-155 targeting neuronal pacemaker ion channels and release of amino acid transmitters during cerebral ischemia.

Authors:
J-J Zhao Y-H Zang Y Liu Y-J Liu J-N Wang

Eur Rev Med Pharmacol Sci 2021 Apr;25(7):3007-3014

Department of Neurology, Qingdao Hospital of Traditional Chinese Medicine (Qingdao Hiser Hospital), Qingdao, Shandong, China.

Objective: Cerebral hemorrhage can cause hemorrhagic stroke, leading to severe brain damage. MiRNA-155 is closely related to the development of stroke. However, the regulatory mechanism of miRNA-155 during cerebral ischemia has not yet been elucidated. Read More

Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, NO.119 Nansihuanxilu, Fengtai District, Beijing, 100160, People's Republic of China.

Spontaneous intracranial hematoma (ICH) is the second leading cause of stroke and has a high risk of postoperative ischemic events (PIEs). But, the evidence on PIEs in ICH patients still lacks. Therefore, a retrospective study was carried out to screen the risk factors for PIEs and construct a visual predictive model. Read More

Restored microRNA-326-5p Inhibits Neuronal Apoptosis and Attenuates Mitochondrial Damage via Suppressing STAT3 in Cerebral Ischemia/Reperfusion Injury.

Authors:
Yumin Huang Yingge Wang Zuowei Duan Jingyan Liang Yijun Xu Shuai Zhang Tieyu Tang

Nanoscale Res Lett 2021 Apr 20;16(1):63. Epub 2021 Apr 20.

Department of Neurology, Affiliated Hospital of Yangzhou University; Yangzhou University, 45 Taizhou Road, Yangzhou, 225001, Jiangsu, People's Republic of China.

Studies have greatly explored the role of microRNAs (miRNAs) in cerebral ischemia/reperfusion injury (CI/RI). But the specific mechanism of miR-326-5p in CI/RI is still elusive. Hence, this study was to unmask the mechanism of miR-326-5p/signal transducer and activator of transcription-3 (STAT3) axis in CI/RI. Read More

Huntington's disease and subcortical vascular dementia display similar dementing features, shaped by different degrees of striatal atrophy, deep white matter degeneration and tau pathology. To investigate the hypothesis that Huntington's disease transcriptomic hallmarks may provide a window into potential protective genes upregulated during brain acute and subacute ischemia, we compared RNA sequencing signatures in the most affected brain areas of 2 widely used experimental mouse models: Huntington's disease, (R6/2, striatum and cortex and Q175, hippocampus) and brain ischemia-subcortical vascular dementia (BCCAS, striatum, cortex and hippocampus). We identified a cluster of 55 shared genes significantly differentially regulated in both models and we screened these in 2 different mouse models of Alzheimer's disease, and 96 early-onset familial and apparently sporadic small vessel ischemic disease patients.

Ferroptosis plays a critical regulatory role for a new kind of cell death initiating and developing an array of disorders like neurological diseases, acute injury of kidney, tumors and ischemia etc. This selective deposition of iron is one of the pathogenic reasons for PD and although it's underlying mechanism is still unknown. In this review, the role of neuroinflammation in Parkinson's disease (PD) leading to neurodegeneration has been discussed in detail. Read More
