Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

A Gut‐Brain Axis Underlying Succinate‐Associated Compulsive‐Like Behavior

open access: yesAdvanced Science, EarlyView.
Gut‐derived succinate is associated with an excitatory‐inhibitory imbalance in dmPFC glutamatergic neurons, involving microglial SUCNR1 activation and vagal afferent signaling via upregulated gut 5‐HT4 receptors along the DVC‐CeA‐dmPFC circuit, changes that are linked to excessive compulsive‐like behavior.

Modulation of the TGF‐β/Smad Signaling Pathway by a Bioactive Oxidized Polygonati Rhizoma Polysaccharide Crosslinked Chitosan Hydrogel as Therapeutic Carrier for Parkinson's Disease Treatment

open access: yesAdvanced Science, EarlyView.
An injectable, self‐healing COPRP hydrogel integrates structurally defined oxidized Polygonati rhizoma polysaccharide with carboxymethyl chitosan through dynamic Schiff‐base crosslinking. The bioactive matrix scavenges reactive oxygen species, suppresses neuroinflammation, protects dopaminergic neurons, and supports sustained levodopa release.

Liquid‐Responsive Shape‐Memory Nanofiber‐Reinforced Scaffolds for Cartilage Repair

open access: yesAdvanced Science, EarlyView.
A liquid‐responsive shape‐memory, nanofiber‐reinforced QCG scaffold combines conformal defect filling, an aligned architecture that is structurally permissive for endogenous cell infiltration, and sustained KGN release. This integrated design enhances BMSC viability, migratory activity, and chondrogenic differentiation and promotes hyaline cartilage ...

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

STING/Type I Interferon Pathway Activation Confers Multimodal Therapeutic Benefits in Osteomyelitis

open access: yesAdvanced Science, EarlyView.
STING/type I interferon signaling counteracts osteomyelitis through coordinated control of pain, bone destruction, and abscess formation. It inhibits pathogen‐induced nociceptor activation, restrains osteoclast‐mediated bone resorption, and suppresses IL‐1β‐driven neutrophil recruitment.
