Potentiating Cerebral Perfusion Normalizes Glymphatic Dynamics in Systemic Inflammation

open access: yesAdvanced 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.

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

open access: yes, 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.

A Patient‐Derived Organoid Biobank of Adamantinomatous Craniopharyngioma as a Platform for Drug Discovery

open access: yesAdvanced Science, EarlyView.
This study successfully establishes adamantinomatous craniopharyngioma (ACP) patient‐derived organoids (PDOs) that preserve the histopathological and genetic features of the original tumors. Through drug sensitivity assays and subsequent mechanistic analyses, the study demonstrates that Ceritinib exerts its inhibitory effects on ACP PDO growth by ...

Effect of Phenylephrine on Cerebrovascular Regulation: A Translational Perspective

open access: yesJournal 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.

Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

open access: yesAdvanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

Pathogenicity of Mediator Complex Subunit 27 (MED27) in a Neurodevelopmental Disorder with Cerebellar Atrophy

open access: yesAdvanced Science, EarlyView.
MED27 is one of the 26 subunits in the human Mediator complex (MED). Neurodevelopmental disorder‐causing MED27 genetic variants induce instability of MED, leading to disrupted DNA occupancy, altered chromatin interaction, and subsequent transcriptional dysregulation of critical downstream genes, including master regulatory transcription factors ...
