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.

Decreased RYR2 Cluster Size and Abnormal SR Ca2+ Release Contribute to Arrhythmogenesis in TMEM43‐Related ARVC

Advanced Science, EarlyView.
The TMEM43 ‐ P386S mutation causes arrhythmogenic right ventricular cardiomyopathy (ARVC) by mislocalizing itself from nuclear envelope (NE) to cytoplasm, disrupting lamin B2 (a novel TMEM43 interactor) localization, NE integrity and chromatin accessibility, causing hyper ‐ phosphorylation and reduced expression/clustering of ryanodine receptor type 2 (

De Novo Heterozygous ZFX Frameshift Variant in a Female With an X‐Linked Neurodevelopmental Disorder

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Germline ZFX variants are associated with an X‐linked neurodevelopmental disorder, with 14 males and 16 females reported to date. We describe a 20‐year‐old female with a heterozygous ZFX frameshift variant, p.(Met666Valfs*2), identified by genome sequencing, previously reported in an affected male.
