Rheumatoid arthritis (RA) is an immune-mediated disease characterized by polyarthritis that affects the small joints of the bilateral upper and lower extremities. RA shares several common clinical symptoms with Sjögren's syndrome (SS), another rheumatic disease caused by the lymphocytic infiltration of exocrine glands, with dry eye and dry mouth being the two most common symptoms. Anti-Ro/SS-A antibodies, a diagnostic biomarker of SS, are positive in patients with RA at a certain rate.

Salivary gland stem/progenitor cells (SSPCs) hold significant potential for regenerative medicine, especially for patients suffering from salivary gland dysfunction due to various causes such as radiation therapy, Sjögren's syndrome, and aging. This review provides a comprehensive overview of SSPCs, including their characteristics, isolation, culture techniques, differentiation pathways, and their role in tissue regeneration. Additionally, we highlight recent advances in cell- and tissue-based therapies, such as SSPC transplantation and bioengineered organ replacements.

Objectives: The research aimed to assess the proportions of Gamma delta (γδ) T cells and the expression levels of CD226, ICOS, CD40L, OX40, TIGIT, LAG-3, Tim-3, and PD-1 on γδ T cells in the peripheral blood of patients diagnosed with primary Sjögren's syndrome (pSS), and to evaluate the clinical significance of these findings.
Methods: Utilizing flow cytometry, we investigated the proportion of γδ T cells and the expression of CD226, ICOS, CD40L, OX40, TIGIT, LAG-3, PD-1, and Tim-3 on γδ T cells in 37 patients diagnosed with pSS and 28 healthy controls (HC). Moreover, we explored the potential associations between the proportion of γδ T cells, TIGIT + γδ T cells, PD-1 + γδ T cells, and TIGIT + PD-1 + γδ T cells with clinical symptoms and laboratory parameters.

The aim of this study was to determine serum I-309 levels in primary Sjögren's syndrome (pSS) patients, as well as the association with disease phenotype, systemic activity, and T helper cell-related cytokines. A total of 58 pSS patients and 30 healthy controls (HC) were enrolled in this study. The concentrations of serum I-309, interleukin-4 (IL-4), IL-6, IL-9, IL-13, IL-17, IL-22, IL-23, tumor-necrosis factor-α (TNF-α), interferon-γ (IFN-γ), IFN-α, and IFN-β were measured with multiplex immunoassay.

Objective: Systemic lupus erythematosus (SLE) and Sjögren disease (SjD) are autoimmune diseases with significant female predominance. The prevalence of SLE is increased in Klinefelter syndrome (KS) compared with the general male population. Our study investigates the dose effects of extra X chromosomes on the development of SLE and SjD in KS and triple X syndrome compared with the general population.
