This study examines the requirement of IL‐23 for IL‐17 production, and the role of the metabolic microenvironment in the expansion of Th<jats:sub>17</jats:sub>‐derived cells in PsA.MethodsPsA patient synovial fluid or peripheral blood Th<jats:sub>17</jats:sub> cell frequencies were evaluated by flow cytometry using CCR6, CD161 and T‐bet as phenotypic markers, and the cytokines IFN‐γ, GM‐CSF and IL‐17 assessed by flow cytometry and ELISA. The impact of IL‐23 and metabolic stress on T cell differentiation was investigated.ResultsPolyfunctional IL‐17<jats:sup>pos</jats:sup> CD4 (p<0.0001) & CD8 (p<0.0001), and GM‐CSF<jats:sup>pos</jats:sup> Th<jats:sub>17</jats:sub>‐derived (p<0.0001) cells were increased in inflamed joints of patients with PsA, with a proportional decrease in patient peripheral blood. We demonstrate IL‐23‐independent IL‐17 release by PsA patient CD4 T cells, where the absence of IL‐23 during Th<jats:sub>17</jats:sub> differentiation reduced IL‐17 by 31±5.8%. Exogenous IL‐23 increased IL‐17, negatively regulated GM‐CSF and co‐operated with TGF‐β to augment IL‐17. Polyfunctional Th<jats:sub>17</jats:sub> and Th<jats:sub>17</jats:sub>‐derived cells, but not Th<jats:sub>1</jats:sub> cells, were expanded by metabolic stress in patients with PsA.ConclusionsWe confirmed the abundance of polyfunctional Type<jats:sub>17</jats:sub> CD4 and CD8 cells in PsA inflamed joints. We demonstrate IL‐23‐independent expansion of Th<jats:sub>17</jats:sub> cells, where IL‐23 negatively regulates GM‐CSF.

Approximately 50% of patients treated with glucocorticoid (GC) monotherapy and 30% of patients receiving adjunctive therapy with tocilizumab experience disease relapses, often during the first 2 years after diagnosis. Although most relapses in GCA do not involve life‐ or organ‐threatening presentations and can be controlled successfully, frequent relapses may lead to increased use of GC and consequent treatment‐related morbidity, in addition to risk of further vascular damage. Emerging data suggests that persistent disease activity may lead to increased vascular morbidity. Additionally, while tocilizumab decreases the frequency of relapses, more than 50% of patients relapse after discontinuation of therapy. Therefore, while interleukin‐6 blockade suppresses disease activity, it does not restore tolerance. In this article, we discuss the practical diagnosis and management of GCA relapses from an expert perspective. Current treatment options for GCA relapses, including those recommended by international guidelines, and novel potential therapies are reviewed.","PeriodicalId":129,"journal":{"name":"Arthritis & Rheumatology","volume":"201 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated ERE expression in early RA (eRA), a period where IFN‐I is increased.MethodsERE expression (LTR5, LINE1, SINE) in disease modifying treatment naïve eRA whole blood and bulk synovial tissue was examined by RT‐PCR and Nanostring alongside IFN‐α activity. Circulating lymphocyte subsets, including B cell subsets, from eRA patients and early psoriatic arthritis (ePsA), were flow cytometrically sorted and similarly examined. Existing established RA and osteoarthritis (OA) synovial single‐cell sequencing data was re‐interrogated to identify repeat elements, and associations explored.ResultsThere was significant co‐expression of all ERE classes and <jats:italic>IFNA</jats:italic> in eRA synovial tissue (n=22, p<0.0001) and significant positive associations between whole blood LINE1 expression (n=56) and circulating IFN‐α protein (p=0.018) and anti‐CCP titres (p<0.0001). ERE expression was highest in circulating eRA B‐cells, particularly naïve B‐cells compared with ePsA, with possible ERE regulation by SAMDH1 implicated and associations with <jats:italic>IFNA</jats:italic> again observed. Finally, in established RA synovium, LTRs, particularly ERVK, were most increased in RA compared with OA where, for all synovial subsets (monocytes, B‐cells, T‐cells and fibroblasts), ERE expression associated with increased IFN‐I signalling (p<0.001).ConclusionsPeripheral blood and synovial ERE expression is examined for the first time in eRA highlighting both a potential causal relationship between ERE and IFN‐I production and an intriguing association with anti‐CCP autoantibodies. This suggests EREs may contribute to RA pathophysiology with implications for future novel therapeutic strategies.","PeriodicalId":129,"journal":{"name":"Arthritis & Rheumatology","volume":"6 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
