Advanced Science, EarlyView.The functionalized starch modifies the mitochondrial surface and encapsulates resveratrol into the cavity of helices, facilitating a novel mitochondrial transplantation platform (MLSR). Upon internalization in recipient cells, MLSR triggers mitophagy and maintains positive autophagic flux through RIP1/RIP3 pathway inhibition.

Advanced Science, EarlyView.A dual‐targeting strategy to rejuvenate aged tendons. A reactive oxygen species (ROS)‐responsive hydrogel co‐delivers a selenium nanozyme (scavenges ROS) and a STING inhibitor to tendon stem cells. This combined action restores mitochondria–nucleus communication, alleviates cellular senescence, and rejuvenates tendon regeneration, offering a novel ...

One‐Step Glycoengineering of NK Cells With High‐Affinity Siglec Ligands for Cancer Immunotherapy
Advanced Science, EarlyView.This study develops an engineered NmCSS enzyme with improved activity for bulky group modified sialic acids, enabling efficient synthesis of structurally diverse sialoside analogs in a single step. Glycan microarray screening identified Siglec high‐affinity ligands, which were incorporated onto natural killer (NK) cells via a one‐pot enzymatic system ...

Advanced Science, EarlyView.Upon inhalation, RM@TNT could persist long‐term in the diseased lungs, while undergoing disintegration to release TNT specifically within the ROS‐rich pathological microenvironments of SA‐ARDS. The released TNT was then precisely delivered to AMs via Tuftsin, where it released Nob intracellularly to activate BMAL1 expression, thus inhibiting AM ...
