These T cells can bind to self- and bacterial-derived peptides, supporting the \"arthritogenic peptide\" hypothesis. Monoclonal antibody-mediated elimination of these expanded T cells has shown potential as a novel treatment for axSpA in a phase II clinical trial, offering a groundbreaking therapeutic approach. In addition to T cells, neutrophils have emerged as important mediators of both inflammation and new bone formation in axSpA, potentially contributing to HLA-B27-independent immune pathomechanisms. Key neutrophil-derived molecules-such as macrophage migration inhibitory factor, hypoxia-inducible factor 1-alpha, caspase recruitment domain-containing protein 9, and neutrophil extracellular traps (NETs)-have been shown in preclinical models to promote Th17-mediated inflammation and reduce regulatory T cell numbers. These mechanisms may be relevant to axSpA pathogenesis and represent potential new therapeutic targets. In recent years, significant progress has been made in understanding the immunopathology of axSpA through both HLA-B27-dependent and -independent mechanisms. However, key questions remain. The pathogenic HLA-B27:05-bound peptides driving CD8⁺ T cell expansion remain unidentified. Moreover, due to the diversity of TCR motifs that recognize self- and microbial peptides, therapies targeting a single TCR (e.g., TRBV9) may have limited efficacy. Further research is needed to clarify axSpA pathogenesis across both pathways.</p>","PeriodicalId":10761,"journal":{"name":"Current Rheumatology Reports","volume":"27 1","pages":"27"},"PeriodicalIF":5.7,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the role of monosodium urate (MSU) crystals is well recognized in activation of innate immunity via inflammasome and NETosis, it is likely that they have a role in triggering adaptive immunity via antigen presenting cells and their autocrine effect on keratinocytes in psoriasis (PSO), ultimately leading to T cell secretion of proinflammatory cytokines such as IL17. Hyperuricemia (HU) is common in PD (up to 30%) and underpins metabolic syndrome comorbidities that are common to both gout and PD. Shared clinical phenotypes and co-morbidities are routinely observed in clinical practice yet there is a paucity of evidence evaluating the effect of treating hyperuricemia/gout on PD activity, with small scale clinical trials showing a positive effect. There were no studies to our knowledge assessing gout disease activity with concurrent treatment of PD. The association between gout and PD is likely due to shared multimorbidity and perhaps to a smaller extent, the direct role of HU in triggering the release of proinflammatory cytokines in PD. There is often a significant overlap in clinical and radiological presentation of gout and Psoriatic arthritis (PsA). In those with atypical response to standard treatments of the primary condition (either gout or PsA), it would be plausible to investigate and treat for the other 'secondary' condition.
