Osteoarthritis (OA) is a progressive joint disease characterized by inflammation and cartilage destruction, its progression closely related to imbalances in the M1/M2 synovial macrophages. A two-pronged strategy for regulation of intracellular/extracellular nitric oxide (NO) hydrogen protons reprogramming macrophages proposed. The combination carbonic anhydrase IX (CA9) siRNA NO scavenger "two-in-one" nanocarriers (NAHA-CaP/siRNA nanoparticles) developed OA therapy scavenging inhibiting CA9 expression In vitro experiments demonstrate that these NPs can significantly scavenge intracellular similar levels as those normal group downregulate mRNA (≈90%), thereby repolarizing M1 into M2 phenotype increasing pro-chondrogenic TGF-β1 (≈1.3-fold), chondrocyte apoptosis.

Abstract Developing nanozymes with effective reactive oxygen species (ROS) scavenging ability is a promising approach for osteoarthritis (OA) treatment. Nonetheless, numerous lie in their relatively low antioxidant activity. In certain circumstances, some of these may even instigate ROS production to cause side effects. To address challenges, copper‐based metal–organic framework (Cu MOF) nanozyme designed and applied OA Cu MOF exhibits comprehensive powerful activities (i.e., SOD‐like, CAT‐like, •OH activities) while negligible pro‐oxidant (POD‐ OXD‐like activities). Collectively, more at various types than other Cu‐based antioxidants, such as commercial CuO single‐atom nanozyme. Density functional theory calculations also confirm the origin its outstanding enzyme‐like activities. vitro vivo results demonstrate that an excellent decrease intracellular levels relieve hypoxic microenvironment synovial macrophages. As result, can modulate polarization macrophages from pro‐inflammatory M1 anti‐inflammatory M2 subtype, inhibit degradation cartilage matrix efficient The biocompatibility protective properties make it valuable asset treating ROS‐related ailments beyond OA.

Abstract MicroRNAs (miRNAs) regulate several physiological and pathological processes involved in various diseases, including osteoarthritis (OA). OA is the most common global musculoskeletal disorder, characterized by irreversible progressive destruction of articular cartilage. Supplementation with exogenous miRNAs may represent a promising therapeutic treatment, miRNA‐124 (miR‐124) being prime candidate for its anti‐inflammatory ability; however, an effective drug delivery system urgently required to enhance miR‐124 stability capacity enter chondrocytes. To this end, tetrahedral framework nucleic acids’ (tFNAs) self‐assembled 3D DNA nanostructures possess superior inherent biocompatibility, versatile functionality, unsurpassed editability, strong cellular internalization ability. In study, tFNAs carrying one or three (T‐miR1 T‐miR3) are successfully synthesized. T‐miR3 largely absorbed via induced inflammatory chondrocytes IL‐1β. With reactive oxygen species’ scavenging ability inflammation‐suppressive release behavior, efficiently protects against IL‐1β injury vitro. Additionally, effectively prevents progression inhibiting chondrocyte apoptosis, smoothing cartilage surfaces, suppressing extracellular matrix degradation, increasing synovial thickness, protecting vivo cartilage, illustrating treatment.
