Glycolytic Enzyme HK2 Phosphorylates nSMase1 to Promote Astrocytic Exosomes Biogenesis Contributing to Acute Ischemic Stroke Injury

Advanced Science, EarlyView.
This study reveals that the glycolytic enzyme HK2 mediates hypoxia‐induced astrocytic exosome biogenesis by directly phosphorylating nSMase1. These astrocytic exosomes impair brain endothelial tight junctions. Astrocyte‐specific knockdown of HK2 reduces exosome release and alleviates brain injury after MCAO.

Single‐Cell Transcriptome Analysis Reveals That Hmga2 Regulates Neuroinflammation and Retinal Function by Modulating Müller Cell Autophagy Through PI3K/AKT Signaling Following MCAO‐Induced Retinal Ischemia

Advanced Science, EarlyView.
Employing snRNA‐seq post‐MCAO‐induced retinal ischemia (RI), this study revealed a novel Hmga2‐high Müller cell subpopulation. Hmga2 knockout alleviated neuroinflammation and RI symptoms, potentially by binding PI3K and regulating Müller cell autophagy.

FOXQ1 Regulates Brain Endothelial Mitochondrial Function by Orchestrating Calcium Signaling and Cristae Morphology

Advanced Science, EarlyView.
FOXQ1 emerges as a master transcriptional regulator of brain endothelial metabolism, orchestrating mitochondrial function through dual control of calcium signaling and cristae organization. This study reveals that brain endothelial cells rely on oxidative phosphorylation rather than glycolysis alone, challenging the current metabolic paradigm and ...

The future of ischemic stroke: flow from prehospital neuroprotection to definitive reperfusion. [PDF]

, 2014
Recent advances in ischemic stroke enable a seamless transition of the patient flow from the prehospital setting to definitive reperfusion, without the arbitrary separation of therapeutic phases of ischemia based on time alone.

Potentiating Cerebral Perfusion Normalizes Glymphatic Dynamics in Systemic Inflammation

Advanced Science, EarlyView.
LPS‐induced systemic inflammation increases glymphatic influx but delays cervical lymphatic drainage, accompanied by AQP4 depolarization and impaired glymphatic clearance. Enhancing cerebral blood flow via the inotropic agent levosimendan effectively restored AQP4 polarization, improving glymphatic flux and amyloid‐β clearance.

Effect of Phenylephrine on Cerebrovascular Regulation: A Translational Perspective

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Phenylephrine is an alpha 1‐adrenergic receptor (α1R) agonist. Evidence indicates activation of α1Rs can initiate both vasoconstrictor and dilator signaling. How phenylephrine affects cerebrovascular regulation remains unclear.

Simulation of a mechanical thrombectomy device based in the use of self-expandable stents for the blood clots extraction [PDF]

, 2011
Recently, we have presented some studies concerning the analysis, design and optimization of one experimental device developed in the UK - GPTAD - which has been designed to remove blood clots without the need to make contact with the clot itself ...

Regulation of Neuroinflammation by Microglial DUBA‐IRAK1‐IKKβ Signaling Loop

Advanced Science, EarlyView.
The protein levels of deubiquitinating enzyme A (DUBA) are rapidly upregulated in microglia after activation of Toll‐like receptor 4 (TLR4). In turn, DUBA potentiates TLR4‐induced proinflammatory signal transduction in microglia by stabilizing interleukin‐1 receptor activated kinase 1 (IRAK1) through K48 deubiquitination.
