TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis

Advanced Science, EarlyView.
A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...

α‐Synuclein Forms Distinct Micelle‐Like Assemblies at Low Ionic Strengths

Advanced Science, EarlyView.
At high ionic strength, α‐synuclein forms diverse assemblies, including oligomers, fibrils, and condensates. Here, we show that at low ionic strength, α‐synuclein adopts a distinct, low‐abundance assembly state. These assemblies maintain a constant size above a critical concentration and do not coalesce, suggesting a micelle‐like organization ...

Usage and Behavioral Data of Consumers Using Hair Dye Products Containing 2-Methoxymethyl-P-Phenylenediamine

Cosmetics
The potent sensitizer PPD is considered a key sensitizer in hair dye contact allergy. Modification of its molecular structure to 2-methoxymethyl-p-phenylenediamine (ME-PPD) reduces its skin sensitizing potency.

Mesenchymal Stromal Cell‐Based Cell–Drug Conjugates for the Treatment of Acute Liver Failure

Advanced Science, EarlyView.
Mesenchymal stromal cell (MSC)‐based cell‐drug conjugates are constructed by anchoring rosiglitazone‐loaded nanoparticles onto the MSC surface. Sustained rosiglitazone release enhances MSC proliferation and paracrine activity while promoting anti‐inflammatory macrophage polarization.

Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

Advanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via

Deubiquitination of Vangl by USP6 and USP32 Regulates Planar Cell Polarity Signaling

Advanced Science, EarlyView.
Compartment‐specific deubiquitination controls Vangl dosage and planar cell polarity signaling. USP6 and USP32 regulate distinct subcellular pools of Vangl by removing distinct ubiquitin modifications from Vangl proteins. This regulatory mechanism safeguards PCP‐dependent embryonic morphogenesis, while aberrant USP32‐dependent stabilization of VANGL ...
