Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography

open access: yesAdvanced Science, EarlyView.
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

PolyG Fibrils Coalesce Into Nuclear Ribbons That Engage Proteostasis Machinery in Neuronal Intranuclear Inclusion Disease

open access: yesAdvanced Science, EarlyView.
In NIID, expanded NOTCH2NLC repeats give rise to nuclear polyG inclusions. Tracer‐guided in situ cryo‐electron tomography enables cross‐scale structural analysis from mouse brain to native neuronal nuclei, revealing dense‐core/peripheral‐halo inclusions built from compact polyG ribbons.

HD‐tDCS Restores Perivascular AQP4 Polarization via PPARγ Modulation to Enhance Glymphatic Clearance After Intracerebral Hemorrhage in Mice

open access: yesAdvanced Science, EarlyView.
HD‐tDCS promotes recovery after intracerebral hemorrhage by enhancing PPARγ‐dependent astrocyte remodeling in a mouse model of ICH. This process suppresses proinflammatory astrocytic activation, restores perivascular AQP4 repolarization, and improves glymphatic influx and efflux, thereby facilitating hematoma and perihematomal edema clearance and ...

Identifying a Csmd3+ Microglial Subpopulation that Drives Cold‐to‐Hot Transition and Immune‐Cure in Glioblastoma

open access: yesAdvanced Science, EarlyView.
The study establishes an immune‐cure (ICu) mouse model based on a TMEMed G422TN‐GBM system that faithfully recapitulates human TMEMed GBM. scRNA‐seq analysis reveals a Csmd3+ microglial subset with innate immune memory (IIM) potential that potently suppresses GBM growth, drives a TME cold‐to‐hot transition, and induces 100% ICu in long‐term survival ...

NSD2 Coordinates the Neurogenic‐to‐Gliogenic Transition via H3K36me2‐Dependent Activation of the EGFR‐ERK Pathway

open access: yesAdvanced Science, EarlyView.
NSD2 coordinates the neurogenic‐to‐gliogenic transition in the developing neocortex through H3K36me2‐dependent activation of EGFR–ERK signaling. Loss of NSD2 disrupts astroglial and oligodendroglial development, whereas ERK activation rescues gliogenic defects in vitro and in vivo.
