Tackling Allergic Airway Inflammation with Organic Sheet‐Like Nanoplatforms by Targeted Elimination of Epithelial Small Extracellular Vesicles

Advanced Science, EarlyView.
In this work, “inorganic‐free” nanosheets, named PNSE are developed using template‐based synthesis technology. The functionalized organic nanosheets exhibit low cytotoxicity, mild protein adsorption, and potent binding efficacy to epithelial sEVs.

Optimized Monothiol Thioredoxin Derivative (ORP100S) Protects In Vitro and In Vivo from Radiation and Chemotoxicity Without Promoting Tumor Proliferation

Advanced Science, EarlyView.
Native thioredoxin‐1 (TRX) stimulates proliferation and rescues stem cells and cancer cells from multiple stressors by suppressing p53 and inhibiting ferroptosis via GPX4/SLC7A11 upregulation mediated by enhanced KLF4 expression and p53 promoter binding.

Smart Gated Hollow Mesoporous Silica Hydrogel for Targeting Endoplasmic Reticulum Stress and Promoting Periodontal Tissue Regeneration

Advanced Science, EarlyView.
The hollow mesoporous silica loaded with quercetin (HM‐QU@PEG) is combined with a thermosensitive anti‐bacterial matrix (TF127) to prepare HQUP@TF127. HQUP@TF127 effectively eliminates excessive ROS, alleviates endoplasmic reticulum stress, relieves mitochondrial calcium overload, and blocks the p53‐dependent apoptotic cascade. Furthermore, it enhances
