It is therefore an attractive agent for the attenuation of inflammatory responses and the development of tolerogenic immunity in autoimmune diseases. To overcome VD3 toxicity and enhance its <em>in vivo</em> performance, nanoparticles (NPs) have emerged as a promising delivery platform. Therefore, in this study, we have developed VD3-loaded polymeric nanoparticles (VD3-NPs) as a therapeutical strategy for the treatment of autoimmune disorders. We demonstrate that VD3-NPs could successfully be generated and that they significantly inhibit secretion of IL-6, IL-10, IL-23, and TNFα in human whole blood cultures. We observed that poly(lactic-co-glycolic acid) (PLGA) NPs are efficiently taken up by neutrophils, monocytes and B cells, prompting further investigation into the effect of VD3-NPs on these subsets. Investigation into each of the immune cell subsets demonstrated that the VD3-NPs were able inhibit cytokine secretion by both monocytes and neutrophils. Moreover, VD3-NPs induced a tolerogenic phenotype in monocytes. In B cells, we observed that VD3-NPs impaired <em>in vitro</em> plasma B cell differentiation and suppressed antibody production. Together, our results validate for the first time in primary human cells the therapeutic potential of VD3 encapsulated in PLGA NPs, posing an attractive strategy for the treatment of autoimmune diseases.</div></div>","PeriodicalId":36425,"journal":{"name":"Journal of Translational Autoimmunity","volume":"11 ","pages":"Article 100321"},"PeriodicalIF":3.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219465","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}

This review highlights the pivotal role of mass spectrometry (MS)-based multi-omics technologies in elucidating AS pathogenesis, identifying disease-specific biomarkers, and advancing precision medicine for AS. The fundamental principles of MS are outlined, encompassing ionization methods like electrospray and matrix-assisted laser desorption/ionization, mass analyzers such as orbitrap and time-of-flight, and separation systems including liquid and gas chromatography. These technologies enable highly sensitive and comprehensive profiling of proteomes, metabolomes, and lipidomes. Proteomics analyses have revealed dysregulated pathways and identified key biomarkers, including complement components, matrix metalloproteinases and the panel “C-reactive protein + serum amyloid A1”, for distinguishing active AS from healthy controls and stable AS. Metabolomics studies emphasize disturbances in tryptophan-kynurenine metabolism and gut microbiome-derived metabolites, including short-chain fatty acids, thereby linking microbial imbalance to inflammatory responses. A combination of three metabolites (3-amino-2-piperidone, hypoxanthine, and octadecylamine) has shown promise as serum biomarkers for AS diagnosis. Lipidomics profiling reveals significant changes in phospholipid composition. Furthermore, emerging single cell technologies (e.g., mass cytometry) have dissected immune heterogeneity in AS, revealing chemokine signaling dysregulation in monocyte and T-cell subclusters. Persistent challenges and future advancements, such as data heterogeneity, cohort limitations, and the interpretability of artificial intelligence models for multi-omics integration were discussed. By integrating technological innovation with clinical insights, this review systematically summarizes multiple potential biomarker panels for AS, in which multi-omics-driven strategies facilitate early diagnosis, mechanistic subtyping, and personalized therapies, ultimately improving patient outcomes in AS.</div></div>","PeriodicalId":36425,"journal":{"name":"Journal of Translational Autoimmunity","volume":"11 ","pages":"Article 100319"},"PeriodicalIF":3.6,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145157596","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}

Dysregulation of the Th17/Treg balance is a key immunological hallmark of RA. Emerging evidence highlights the critical role of gut microbiota-derived short-chain fatty acids (SCFAs) in maintaining immune homeostasis. This review systematically elucidates how SCFAs modulate the Th17/Treg equilibrium through three synergistic mechanisms: (1) metabolic reprogramming via AMPK/mTOR signaling, (2) epigenetic regulation by inhibiting HDAC, and (3) modulation of cytokine cascades. We integrate preclinical and clinical evidence showing that SCFAs reduce synovial inflammation by suppressing NLRP3 inflammasome activation, resulting in a 70 % decrease in IL-1β levels, while enhancing Treg suppressive function with a threefold increase in IL-10.
