This leads to pronounced dryness of the mouth and eyes and can result in multi-systemic involvement affecting the kidneys, lungs, and blood. In recent years, there has been increasing attention on the role of immune cells in pSS.

These included IgD+ CD38br AC B cells, CD27 on IgD+ CD38− unswitched memory B cells, and Granulocyte % leukocyte. Additionally, three immune cells with reduced levels were found to be causally associated with pSS risk, namely CD4+ CD8dim %lymphocyte, CD4+ CD8dim %leukocyte, and CD28 on activated and secreting regulatory T cells (Tregs). Furthermore, the development of pSS was associated with elevated levels of CD33br HLA DR+ CD14− % CD33br HLA DR+ in myeloid cells.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>This study demonstrates that immune responses influence the progression of pSS in a complex pattern. Our findings may provide new insights into the immunology of pSS pathogenesis and more experimental studies should be conducted to further explore the potential mechanisms between identified immune features and pSS risk, which may provide a basis for exploring early intervention methods for pSS and developing targeted therapeutic strategies or even reshaping immune homeostasis.</p>\u0000 </section>\u0000 </div>","PeriodicalId":14330,"journal":{"name":"International Journal of Rheumatic Diseases","volume":"27 11","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PsA occurs in about one-third of psoriasis patients [<span>3</span>]. Dysregulation of several molecules, including proinflammatory interleukins (ILs), interferons (IFNs), growth factors, and colony-stimulating factors (CSF) act as ligands for receptors connected to intracytoplasmic Janus kinases (JAKs). Consequently, JAKs activate signal transducer and activator of transcription (STAT) proteins, which translocate to the nucleus and induce the expression of inflammatory nuclear factor. The JAK/STAT pathways play a central role in the development and pathogenesis of PsA [<span>4, 5</span>]. Several studies have reported increased activation of JAK1/STAT3/STAT1, which may contribute to the articular inflammatory process characterized by the expansion of Th17 effector cells in the synovial fluid of patients with active PsA [<span>6, 7</span>]. By targeting these JAK/STAT pathways, JAK inhibitors effectively reduce inflammatory responses [<span>7-9</span>].</p><p>JAK inhibitors, including tofacitinib and upadacitinib, effectively target these pathways to reduce inflammation and improve symptoms in PsA patients. However, emerging evidence has raised concerns regarding the cardiovascular (CV) risks associated with JAK inhibitors. Both clinical trials and post-marketing surveillance have reported higher incidences of thromboembolism and other CV events in patients using these therapies, particularly at higher doses. Given the growing use of JAK inhibitors in PsA management, understanding the underlying mechanisms of CV risk is crucial for optimizing patient safety.</p><p>Since the publication of the Oral Surveillance Study [<span>10</span>], the use of JAK inhibitors has raised concerns regarding the potential increased risk of CV disease (CVD) in PsA patients. All known cytokines and chemokines create a unique network of self-interactions, activation and regulatory loops. Theoretically, inhibition of JAK should translate into reduction of both autoimmune diseases' activity and reduction of prothrombotic risk. However, JAK inhibitors are less specific than biologics due to the inherent redundancy of the JAK/STAT pathway and therefore may display an increase in off-target effects, which may be related to the association of increased Major Adverse Cardiovascular Events (MACE) and Venous Thromboembolism (VTE) observed [<span>11</span>].</p><p>The etiology of thrombotic tendency in PsA may also be linked to other mechanisms and causal factors, including antiphospholipid antibodies, hyperhomocysteinemia, and inflammation.
