Force‐Electric Nanotentacles of Tantalum Implant Accelerate Cellular Energy Metabolism/Crosstalk for Immunomodulation‐Vascularized Bone Integration

Advanced Science, EarlyView.
A biomimetic force‐electric nanotentacle‐enabled tantalum (Ta) implant with surface‐nanostructured LiTaO3 (n‐LiTaO3) was first developed via laser nanofabrication combined with Li+‐induced in situ reaction, enabling the transduction of ultrasound into bioelectrical cues.

AHR‐Responsive Carbon Dots Orchestrate Skin Wound Healing and Colonic Mucosal Repair via Treg‐Mediated Macrophage Efferocytosis

Advanced Science, EarlyView.
Guided by pharmacophore modeling and molecular docking, aryl hydrocarbon receptor (AHR)‐responsive carbon dots were synthesized. They bind directly to AHR and expand gut‐resident regulatory T (Treg) cells. Treg‐derived C‐C motif chemokine ligand 1 (CCL1) enhances macrophage efferocytosis, creating a pro‐regenetative niche that promotes colonic mucosal ...

Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

Advanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

PIAS3 CircRNA‐Loaded Lipid Nanoparticles Restore ALOX15 SUMOylation to Suppress Cementoblast Ferroptosis and Attenuate Orthodontically Induced Root Resorption

Advanced Science, EarlyView.
Orthodontic compression suppresses PIAS3 expression in cementoblasts, impairing ALOX15 SUMOylation and ubiquitin‐mediated degradation, which leads to ALOX15 accumulation, lipid peroxidation, ferroptosis, and osteoclastogenesis. Local delivery of PIAS3 circRNA‐loaded lipid nanoparticles restores the PIAS3–ALOX15 regulatory pathway, alleviates ...
