However, their therapeutic potential and underlying mechanisms in allergic rhinitis (AR) remain unexplored. The intranasal delivery of monascin for treating AR faces the challenge of rapid clearance. Herein, to achieve sustained and prolonged release, we developed monascin-encapsulated poly(lactic <i>co</i> glycolic acid) nanoparticles (PLGA-MS) by the mechanical double emulsion technique, enabling effective local delivery of monascin for the treatment of AR. Histopathological staining, flow cytometry, ELISA, and network pharmacology were used to assess therapeutic effects and potential mechanisms of monascin in treating AR. In vitro and in vivo experiments revealed that PLGA-MS exhibited enhanced stability, excellent drug encapsulation capacity, and sustained drug release. PLGA-MS treatment showed a significant therapeutic effect in AR mice by decreasing inflammatory cells in nasal tissue and regulating IgE, histamine, and a variety of cytokines. PLGA-MS treatment decreased T helper 2 cells (Th2) and T helper 17 cells (Th17) while promoting and increasing Tregs (regulatory T cells). Further analysis showed elevated levels of IL-10 and TGF-β expression in Tregs post-treatment. Results of the CCK-8 assay, pathological analysis of vital organs, and serum analysis of liver and kidney functions demonstrated the biosafety of PLGA-MS. Additionally, network pharmacology identified immune response pathways that may support PLGA-MS's immunomodulatory effects in AR.

Upon near-infrared light (NIR, 808 nm) stimulation, this coating exhibits synergistic antibacterial and osteogenic effects through photothermal (PTT) and photodynamic (PDT) processes. Characterization results indicate that the Ag-Cu NPs are uniformly distributed within the coating (Ag: 1.7 wt %, Cu: 2.0 wt %), and the concentrations of Ag<sup>+</sup> and Cu<sup>2+</sup> released (2.9526 mg·L<sup>-1</sup> and 0.1932 mg·L<sup>-1</sup>, respectively) are significantly lower than the cytotoxic threshold (10 mg·L<sup>-1</sup>). PTT tests reveal that the coating achieves a PTT conversion efficiency of 33.8%, with the temperature rising to 49.9 °C within 10 min under 1.0 W·cm<sup>-2</sup> irradiation, generating high levels of singlet oxygen (<sup>1</sup>O<sub>2</sub>). This leads to a 100% bactericidal rate against <i>Escherichia coli</i> and <i>Staphylococcus aureus</i>. In vitro biocompatibility assays show that the gradient release of HA and the synergistic effect of Ag<sup>+</sup>/Cu<sup>2+</sup> significantly enhance the proliferation of bone marrow mesenchymal stem cells (BMSCs), with optical density reaching 1.49 after 7 days of culture. Additionally, osteogenic differentiation is promoted, as evidenced by a 2.9-fold increase in alkaline phosphatase (ALP) activity and a 2.1-fold increase in calcium nodule formation. Western blot analysis further confirmed that the coating induces the high expression of Runx2 via activation of the Wnt/β-catenin signaling pathway, thereby driving osteogenesis. This study presents a strategy for the development of smart implants with both efficient antibacterial and bone integration capabilities.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":"6326-6338"},"PeriodicalIF":4.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
