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.

Effects of immobilization on articular cartilage: Autohistoradiographic findings with S35 [PDF]

open access: yes
The effect of immobilization on the articular cartilage of rabbits was studied by light microscope. The knee joint of each rabbit was immobilized in a plaster in a position midway between flexion and extension for a 10 to 120 days period.

Optical non-destructive evaluation of articular cartilage integrity: A review [PDF]

open access: yes, 2011
This paper reviews the current status of the application of optical non-destructive methods, particularly infrared (IR) and near infrared (NIR), in the evaluation of the physiological integrity of articular cartilage.

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.

Inhibition of Heat Shock Protein 90β by Catalpol: A Potential Therapeutic Approach for Alleviating Inflammation‐Induced Cartilage Injuries in Osteoarthritis

open access: yesAdvanced Science, EarlyView.
The schematic diagram delineates the chondroprotective effects of Ca‐bMSN in OA models. The upper portion of the diagram depicts the synthesis process of Ca‐bMSN. The lower section illustrates the post‐injection of Ca‐bMSN in joint cavity, catalpol released and subsequently mediates the reduction of oxidative stress, ECM catabolism, apoptosis, and ...

The superficial zone of articular cartilage

open access: yesInflammation and Regeneration, 2022
AbstractThe superficial zone of articular cartilage contributes to smooth joint motion through the production of proteoglycan 4 (PRG4), also known as lubricin. Recent studies indicate novel effects of PRG4 as a signaling molecule, other than a simple extracellular matrix protein.

DNA Origami‐Based CD44‐Targeted Therapy Silences Stat3 Enhances Cartilage Regeneration and Alleviates Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
This study develops a cartilage‐targeted DNA origami system (OCS) that protects and delivers si‐Stat3 to chondrocytes. OCS reduces MMP13 expression, enhances extracellular matrix stability, and lowers oxidative stress while improving cell survival. In vivo, OCS decreases cartilage degradation biomarkers and promotes tissue repair factors, demonstrating

Functionalized Biomimetic Nanoparticles Targeting the IL‐10/IL‐10Rα/Glycolytic Axis in Synovial Macrophages Alleviate Cartilage Degeneration in Osteoarthritis

open access: yesAdvanced Science, EarlyView.
The MOF material UIO‐66‐NH2 is functionalized with DBCO groups on its surface, encapsulating NO‐prednisolone and conjugating it with azide‐modified IL‐10. Finally, the complex is extruded with MM to form biomimetic functional nanoparticles. Upon intra‐articular injection, MI@UN, enveloped by the MM, specifically targets synovial macrophages, is ...

Liquid Metal Sloshing for High‐Load Active Self‐Healing System: An Application to Tendon‐Driven Legged Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
Liquid metal “sloshing” by the robot's own actuator is proposed to improve the self‐healing performance. The proposed method drastically enhances the healed strength by decomposing the surface oxides and the impurities. The method contributes to the world's first demonstration of active self‐healing behavior performed by a life‐sized legged robot. Self‐
