Targeted H2S Delivery System Attenuates Blood‐Spinal Cord Barrier Disruption after Spinal Cord Injury by Reshaping the Ferritinophagy Pathway

open access: yesAdvanced Science, EarlyView.
The αvβ3‐mediated SPRC@MPDA‐RGD targets broken endothelial cells and controllably releases SPRC. CSE is then activated to produce endogenous H2S, which inhibits ferritinophagy. In brief, H2S inhibits autophagy by activating the PI3K/Akt/mTOR pathway, thereby suppressing the ferroptosis process mediated by NCOA4, and ultimately promoting the ...

Adipocyte‐Derived Exosomal miR‐5099 Mitigates M1 Macrophage Polarization and Adipose Inflammation via c‐Met/NF‐κB Axis to Improve Metabolic Health

open access: yesAdvanced Science, EarlyView.
Celastrol upregulates adipocyte‐derived exosomal miR‐5099, suppressing the macrophage c‐Met/NF‐κB axis to mitigate pro‐inflammatory M1 polarization and adipose inflammation. These miR‐5099‐enriched exosomes also act as endocrine signals targeting the liver, muscle, and adipocytes to significantly enhance systemic insulin sensitivity.

Liver Stiffness Rises Early in MASLD and Drives Inflammation, Lipid Dysmetabolism, and Fibrosis via Piezo1–YAP Mechanotransduction

open access: yesAdvanced Science, EarlyView.
Progressive stiffening of the hepatic extracellular matrix and free fatty acid overload activate the mechanosensor Piezo1 in steatotic hepatocytes, inducing calcium influx and nuclear translocation of Yes‐associated protein. YAP‐dependent nuclear signaling further drives inflammatory and fibrotic gene programs, lipid metabolic reprogramming, and ...

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

open access: yesAdvanced Science, EarlyView.
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

open access: yesAdvanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...
