Nasal Delivery of Engineered Exosomes via a Thermo‐Sensitive Hydrogel Depot Reprograms Glial Cells for Spinal Cord Repair

Advanced Science, EarlyView.
Engineered macrophage‐derived exosomes overexpressing GNA12 and GNA13 reprogram glial cells to promote neuroprotection and neural regeneration following SCI. A chitosan‐based thermosensitive hydrogel enables sustained intranasal exosome delivery, bypassing systemic barriers and enhancing therapeutic efficacy.

Adaptive Antioxidant Nanomedicines Inhibit Ferroptosis in Renal Tubular Epithelial Cells to Alleviate Diabetic Kidney Disease

Advanced Science, EarlyView.
In this study, an adaptive antioxidant nanodrug (AAN) is developed through the self‐polymerization of L‐selenocysteine. The AAN exhibits dual functionalities: antioxidant activity (scavenging reactive oxygen species) and mitochondrial targeting. Moreover, the released selenium (Se) participates in the synthesis of glutathione peroxidase 4 (GPX4), which
