The diversity of microbial triggers supports the hypothesis that KD arises from immune-mediated responses rather than direct infection. Pathogen-associated molecular patterns (PAMPs), microbe-associated molecular patterns (MAMPs) and inflammatory cell death-linked damage-associated molecular patterns (DAMPs) play critical roles in KD pathogenesis. Furthermore, genetic polymorphisms associated with KD, such as <i>ITPKC</i>, <i>CASP3</i>, and <i>FCGR2A</i>, contribute to immune activation by promoting inflammasome activation, pyroptosis and antibody-dependent enhancement (ADE), thereby intensifying inflammation. Oxidative and nitrative stress further amplify inflammatory responses, with their interplay potentially driving KD onset. The relatively low recurrence rate of KD, despite its diverse triggers, may partly be explained by the presence of anti-DAMP antibodies. Historically, reduced exposure to infections and improved sanitation may have led to lower levels of anti-DAMP antibodies, potentially contributing to the increased incidence of KD observed over time.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Continued research into microbial and immune mechanisms is crucial to advance our understanding of KD pathogenesis.</p>\u0000 </section>\u0000 </div>","PeriodicalId":13289,"journal":{"name":"Immunity, Inflammation and Disease","volume":"13 9","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12477333/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145185572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Danggui buxue decoction (DBD), renowned for its qi-tonifying, blood-nourishing, and anti-inflammatory properties, has shown promising potential in the management of RA. This study investigates the mechanisms of DBD in RA through bioinformatics and experimental analyses, providing a scientific foundation for its clinical application and further development.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>The chemical components and blood-absorbed components of DBD were identified using UPLC-MS/MS. Bioinformatics approaches were applied to identify differentially expressed genes (DEGs) between RA patients and healthy individuals, and to predict potential drug targets and signaling pathways associated with the blood-absorbed components of DBD. Collagen-induced arthritis (CIA) rat models and tumor necrosis factor (TNF)-α-stimulated human rheumatoid arthritis fibroblast-like synoviocyte (RA-FLS) models were established to evaluate the therapeutic effects of DBD on RA. Serum metabolomics analysis was performed to identify differential metabolites and key metabolic pathways associated with the therapeutic effects of DBD.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>A total of 83 chemical components and 34 blood-absorbed components were identified in DBD. Bioinformatics analysis highlighted the NF-κB signaling pathway as a central regulator of RA-related inflammation, requiring further mechanism exploration. Experimental findings demonstrated that DBD significantly reduced the expression of inflammatory cytokines-IL-1β, IL-6, and TNF-α-in both RA-FLS cells and serum from CIA rats. Furthermore, DBD inhibited RA-FLS cell proliferation and migration while inducing apoptosis. DBD treatment alleviated paw swelling, reduced arthritis scores, and decreased spleen and thymus indices. Histopathological examination (HE) staining showed decreased inflammatory cell infiltration, and Micro-CT results revealed notable mitigation of bone destruction. Metabolomic analysis identified 34 differential metabolites and 4 significant metabolic pathways (<i>p</i> < 0.05). Moreover, DBD significantly downregulated the expression of phosphorylated proteins in both RA-FLS cells and synovial tissue of rats involved in the NF-κB signaling pathway, including p-IκBα, p-p65, and p-IKKα, and suppressing NLRP3 protein and mRNA expression of IκBα, p65, and IKKα.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 ","PeriodicalId":13289,"journal":{"name":"Immunity, Inflammation and Disease","volume":"13 9","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12439196/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145069438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
