Astrocytic Ketogenesis Protects Central Nervous System Injury via CPT1A Stabilization and Epigenetic Regulation

open access: yesAdvanced Science, EarlyView.
A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...

Plasma Membrane Lipid Asymmetry Dynamically Regulates Passive Diffusion

open access: yesAdvanced Science, EarlyView.
Passive diffusion enables hydrophobic molecules to cross the plasma membrane and exert their biological functions. This study demonstrates that plasma membrane lipid asymmetry, dynamically regulated by lipid scrambling, determines membrane permeability to lipophilic molecules and thereby modulates their cellular activities.

Non‐Canonical Function of DDX21 in Fetal Hematopoiesis Antagonizes KDM5A‐Mediated Repression of Ribosomal and Hematopoietic Genes

open access: yesAdvanced Science, EarlyView.
This study demonstrates a mechanism by which RNA helicase DDX21 coordinates the transcription of hematopoietic and ribosomal genes by interacting with the H3K4me3 demethylase KDM5A. The DDX21‐KDM5A complex co‐occupies active genes in hematopoietic progenitors, thereby ensuring their rapid proliferation during fetal hematopoiesis.

A Novel Bioactive Component, Efoba, From Aged Garlic Targets CTSC to Suppress NET‐Driven Neuroinflammation and Ameliorate Secondary Brain Injury After Intracerebral Hemorrhage

open access: yesAdvanced Science, EarlyView.
Efoba, a novel bioactive component derived from aged garlic, confers neuroprotection against intracerebral hemorrhage. It acts on microglia to suppress CTSC release, inhibits NET‐mediated neural injury, and blocks pathological microglia‐neutrophil crosstalk. This study provides a highly promising lead compound for hemorrhagic‐stroke therapy.

Injectable Peptide‐Based Functional Amyloid Hydrogels as Tunable Depots for Sustained Drug Delivery

open access: yesAdvanced Science, EarlyView.
An injectable and tunable peptide‐based functional amyloid hydrogel provides sustained insulin release while preserving insulin stability and bioactivity. The hydrogel enables prolonged glycemic regulation in vivo, exhibits excellent biocompatibility, and shows no detectable IAPP and α‐Syn heterologous cross‐seeding, highlighting its potential as a ...

Membrane‐Targeted Nanoparticles for Neuronal Photomodulation

open access: yesAdvanced Science, EarlyView.
Immobilizing gold nanoparticles on the neural interface using a bioorthogonal approach generates localized heat upon exposure to near‐infrared light, temporarily inhibiting primary neuronal activity without damaging the cells. This precise placement and retention of nanoparticles at the cell membrane expand the strategies for non‐invasive neural ...
