Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

Advanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

SIRT7‐Mediated H2BK120 Succinylation Drives Aberrant Mitophagy in Sepsis‐Associated Cognitive Dysfunction

Advanced Science, EarlyView.
Sepsis triggers hippocampal SIRT7 loss, promoting histone H2B succinylation and activation of the PD‐1/PD‐L1–PINK1 axis. This metabolic‐epigenetic cascade drives aberrant mitophagy and neuronal injury, ultimately causing cognitive deficits. Targeting SIRT7‐dependent succinylation offers a potential strategy to protect brain function during sepsis ...

Beyond Biomimetics: Pathology‐Informed Engineering Rescues Reconstituted HDL From Inflammatory Dysfunction for Sepsis Immunotherapy

Advanced Science, EarlyView.
A pathology‐informed engineering strategy rescues reconstituted HDL from inflammatory dysfunction in sepsis. By integrating a ceria nanozyme‐celastrol coordination complex, the platform preserves HDL structure and endotoxin handling, sustains hierarchical intracellular delivery, and enhances immunoregulation across pathological models, translating ...

Magneto‐Sono‐Enhanced Nanozyme Catalysis Drives ROS‐Mediated Pathogen Killing and Mitophagy‐Linked Inflammation Control in Bacterial Pneumonia

Advanced Science, EarlyView.
Nebulized BN@NF nanozymes integrate boron nanosheets with Nd‐doped iron phosphide to form a sono‐magneto‐responsive Z‐scheme heterostructure. Under ultrasound and magnetic activation, BN@NF amplifies ROS generation, eradicates bacteria, disrupts biofilms, and reshapes pulmonary inflammation through NF‐κB suppression, mitophagy promotion, and M1‐to‐M2 ...

Sea Cucumber‐Inspired Double‐Network Biopolymer Hydrogels for Programmable Soft Machines

Advanced Science, EarlyView.
Inspired by the mutable dermis of sea cucumbers, the collagen‐alginate double‐network elastomeric (CoDE) hydrogel achieves programmable, recoverable, and functional mechanical behavior. The CoDE hydrogel mimics the mutable stiffness of the sea cucumber dermis through a densified collagen cryogel scaffold that is secondarily reinforced by a dissipative,
