Formation of Condition‐Dependent Alpha‐Synuclein Fibril Strain in Artificial Cerebrospinal Fluid

open access: yesAdvanced Science, EarlyView.
α‐synuclein aggregation in artificial cerebrospinal fluid (aCSF) leads to a distinct conformation with an electron density pocket motif found in aggregates from PD and MSA patients. Such fibrils has low stability outside the reaction conditions, hinting about the influence of cerebrospinal fluid components not only on the formation, but also on the ...

Sabotaged Integral HSC Heterogeneity Underlies Essential Thrombocythemia Development

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA sequencing (scRNA‐seq) maps how distinct driver mutations remodel hematopoietic stem cell (HSC) programs across essential thrombocythemia (ET). Comparative analysis uncovers both shared and subtype‐specific molecular signatures, identifies a triple‐negative (TN)‐associated HSC population enriched with malignant traits, and reveals the ...

CircSMEK1 Suppresses HCC via the hnRNPK‐IGF2‐AKT Axis: A Diagnostic Biomarker and Therapeutic Target

open access: yesAdvanced Science, EarlyView.
CircSMEK1 is downregulated in MASH/HCC and predicts poor prognosis. It suppresses tumor progression by promoting hnRNPK ubiquitination and inhibiting the IGF2/PI3K/AKT axis, while its loss activates immunosuppressive cancer‐associated fibroblasts. Serum circSMEK1 serves as a non‐invasive diagnostic biomarker, and its restoration potently inhibits HCC ...

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.

Microglial Deletion of Hrh4 Alleviates Alzheimer's Disease Pathologies by Enhancing Microglial Phagocytosis of Amyloid‐β and Tau

open access: yesAdvanced Science, EarlyView.
Histamine H4 receptor (H4R) antagonist VUF6002 mimics low‐dose X‐ray irradiation in aged Alzheimer's disease (AD) mice, enhancing microglial clearance of amyloid‐beta/hyperphosphorylated tau aggregates and restoring cognition. Microglial H4R deletion activates cAMP/TGF‐β1/Smad3 pathway, enhancing phagocytosis, while TGF‐β receptor 1 deletion abolishes ...
