Erythropoietin‐Stimulated Macrophage‐Derived Extracellular Vesicles in Chitosan Hydrogel Rescue BMSCs Fate by Targeting EGFR to Alleviate Inflammatory Bone Loss in Periodontitis

open access: yesAdvanced Science, EarlyView.
A therapeutic strategy is proposed for periodontitis using extracellular vesicles derived from EPO‐stimulated macrophages (EPO‐EVs). This schema demonstrates how EPO‐EVs enhance the osteogenic activity of mBMSCs in an inflammatory environment by inhibiting EGFR.

Hypothalamus Regulates Anabolic Metabolism of Articular Cartilage Superficial Chondrocytes through PGE2 Skeletal Interoception

open access: yesAdvanced Science, EarlyView.
Hypothalamus sympathetic norepinephrine inhibits regeneration of articular cartilage. Mechanical loading on bone during animal activity elevates PGE2 skeletal interoception to promote an anabolic renewal of the superficial membrane by downregulation of norepinephrine for articular cartilage proper thickness and integrity.

Mechanical Load‐Induced Upregulation of Talin2 through Non‐Canonical Deubiquitination of OTUB1 Drives Facet Joint Osteoarthritis Pathogenesis

open access: yesAdvanced Science, EarlyView.
Facet joint osteoarthritis (FJOA), prevalent in the elderly, involves Talin2 upregulation promoting ECM degradation while suppressing synthesis. Mechanical load stabilizes Talin2 via OTUB1‐mediated non‐canonical deubiquitination, driving CCL2 expression that recruits immune cells, exacerbating inflammatory joint degeneration.

Bacterial Capture‐Killing Capsules with Remodeling Bone Immune Microenvironment for the Effective Treatment of Osteomyelitis

open access: yesAdvanced Science, EarlyView.
The PC‐O@TOB capsules are designed to exhibit bactericidal effects, regulate the bone immune microenvironment by promoting M2 macrophage polarization, eliminate excessive ROS, and enhance bone regeneration, providing a novel multi‐dimensional approach for the treatment of osteomyelitis.

Therapeutic Potential of Lipid Nanoparticle‐Encapsulated CD19‐Targeting mRNAs in Lupus and Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
This study develops lipid nanoparticle‐encapsulated mRNA‐encoding antibodies (mRNab‐LNPs) targeting CD19, demonstrating robust anti‐CD19 antibody production in vivo. Intramuscular injection of mRNab‐LNPs reduces CD19+ B and plasma cells in lupus and rheumatoid arthritis mice, significantly alleviating histopathological changes and tissue injuries of ...

Biomedical Applications of Gadolinium‐Containing Biomaterials: Not Only MRI Contrast Agent

open access: yesAdvanced Science, EarlyView.
This paper summarizes the latest applications and potential mechanisms of the rare earth element gadolinium in biomedical fields, in addition to its traditional application as an MRI contrast agent, including osteogenesis, antimicrobial, antitumor, bioimaging, bioprobes, and so on.

Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

open access: yesAdvanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.
