Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

Advanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

Advanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

Advanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

Developmentally Guided Differentiation of Ventral Midbrain Dopaminergic Cells Validated in Proteopathy‐Based Parkinson's Disease Models

Advanced Science, EarlyView.
A developmentally guided protocol reproducibly specifies EN1‐positive ventral midbrain dopaminergic (vmDA) progenitors from human pluripotent stem cells and yields functional vmDA neurons. Optogenetic induction of α‐synuclein aggregation elicits selective degeneration of TH‐positive neurons in 2D cultures and 3D neurospheroids, while transplanted ...

Huntingtin Aggregate‐Responsive Autophagy Gene Circuit Mitigates Disease Pathology in R6/2 Mice

Advanced Science, EarlyView.
CD98‐mediated receptor‐mediated transcytosis enables LIP‐CD98 nanocarriers to cross the blood–brain barrier and deliver ARAA to neurons. mHTT aggregates activate the 11G–NarX sensor, initiating Auto‐P and Trans‐P signaling through the VP48–NarL relay.

In Situ Photo‑Crosslinked Functional Bilayer Hydrogel Modulates Local Microenvironment and Remyelination After Optic Nerve Injury

Advanced Science, EarlyView.
A blue‐light‐crosslinked bilayer hydrogel was developed for local optic nerve repair. The adhesive GM‐Odex outer layer seals and anchors the lesion, while the non‐adhesive GM‐imid inner layer releases MPDA‐Cle without obstructing CSF flow. This system modulates oxidative and inflammatory microenvironments, supports oligodendrocyte differentiation and ...

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

Advanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

Advanced Intelligent Discovery, EarlyView.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...
