The application of susceptibility⁃weighted imaging in cerebral vascular disease

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2022
Susceptibility ⁃weighted imaging (SWI) is a type of MRI developed based on gradient echo sequence (GRE). It is extremely susceptible to paramagnetic substances.

Circular RNA PTPN4 Contributes to Blood‐Brain Barrier Disruption during Early Epileptogenesis

open access: yesAdvanced Science, EarlyView.
Epileptic condition induces CircPTPN4 upregulation, which promotes ECE‐1 expression through competitive sequestration of miR‐145a‐5p. The elevated ECE‐1 catalyzes the ET‐1 production, leading to p38/MAPK pathway activation and subsequent downregulation of tight junction protein expression. This cascade results in increased BBB permeability and enhanced

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.

Robotic Semi-Automated Transcranial Doppler Assessment of Cerebrovascular Autoregulation in Post-Concussion Syndrome: Methodological Considerations

open access: yesNeurotrauma Reports, 2020
Post-concussion syndrome (PCS) refers to a constellation of physical, cognitive, and emotional symptoms after traumatic brain injury (TBI). Despite its incidence and impact, the underlying mechanisms of PCS are unclear.

Multimodal Imaging Reveals Cerebral Microcirculation Dynamics and Mechanisms in Mouse Central Nervous System After Intranasal Infection With Recombinant Pseudorabies Virus

open access: yesAdvanced Science, EarlyView.
Multi‐modality imaging strategy applied to PRV‐induced central nervous system infection enables dynamic visualization of cerebrovascular dysfunction, including hyperemia, hypoperfusion, and vascular remodeling. These changes are linked to microglial activation and impaired angiogenesis, providing mechanistic insight into PRV neuropathogenesis and ...
