Osteoarthritis (OA) is a common degenerative joint disease that progressively destroys articular cartilage, leading to increased friction and severe pain. Therefore, OA can be treated by restoring the lubricating properties of cartilage. In this study, recent advances in lubricants for treatment are reviewed both single-function multifunctional lubricants. Single-function mainly include glycosaminoglycans, lubricin, phospholipids, whereas composed anti-inflammatory bifunctional hydrogels, stem cell-loaded drug-loaded nanoparticles. This review emphasizes importance lubrication capacity explores structural features, properties, role these modulating intracellular inflammatory responses metabolism. Current challenges future research directions field also discussed, with aim providing scientific basis new ideas clinical OA.

In nature, dynamic liquid interfaces play a vital role in regulating gas transport, as exemplified by the adaptive mechanisms of plant stomata and liquid-lined alveoli, which enable efficient exchange through reversible opening closing. These biological processes provide profound insights into design advanced control technologies. Inspired these natural systems, gating membranes have been developed utilizing capillary-stabilized liquids to achieve precise fluid regulation. offer unique advantages rapid responses, stain resistance, high energy efficiency. Particularly, they break limitations traditional solid, porous transport. This perspective introduces bioinspired valve (LGVMs), emphasizing their opening/closing mechanism. It highlights how external stimuli can be exploited advanced, multi-level active or passive regulation strategies. Diverse applications flow selective transport are discussed. While challenges related controllability, long-term stability, scalable production persist, advancements unlock significant opportunities for groundbreaking innovations across diverse fields, including purification, microfluidics, medical diagnostics, harvesting

Many studies now emphasize the intricate relationship between lipid metabolism and osteoarthritis (OA), a leading cause of disability. This narrative review examines alterations in levels phospholipids (PLs) sphingolipids (SLs) synovial fluid (SF), plasma, serum, articular tissues; discusses their role joint lubrication, inflammation, cartilage degradation; describes potential as diagnostic markers therapeutic targets. Key findings include stage-dependent elevated specific PLs SLs SF, blood, tissue OA patients, implicating them possible biomarkers disease severity progression. Studies suggest that beyond involvement these lipids individual species, such lysophosphatidylcholine (LPC) 16:0, lysophosphatidic acid (LPA), ceramide-1-phosphate (C1P), sphingosine-1-phosphate (S1P), contribute to pain, degradation joints through various signaling pathways. Cross-species comparisons dogs mice experience similar lipidomic changes during humans, rendering valuable models for studying lipid-related mechanisms. SF appear originate primarily from blood capillaries diffusion. In addition, are produced locally by fibroblast-like synoviocytes (FLSs) influenced cytokines growth factors regulate biosynthesis lubrication. Emerging research has identified genes UGCG ESYT1 regulators OA. Further, we examine suitability targeting PL SL pathways treat OA, emphasizing need further translate into clinical applications.
