    Article Snippet: Background: Wanbi Hantong Yin (WHY), a traditional Chinese medicine (TCM) formulation, has demonstrated therapeutic efficacy in rheumatoid arthritis (RA).. However, its underlying molecular mechanisms remain largely unclear.. This study combined bioinformatics analyses, including network pharmacology, molecular docking, and molecular dynamics (MD) simulation, with in vivo validation to elucidate the pharmacological mechanisms of WHY in the treatment of RA.

    Article Title: IFN-γ-primed MSC extracellular vesicles attenuate rheumatoid arthritis via PD-L1-driven T-cell suppression and bone preservation.
    Article Snippet: Rheumatoid arthritis (RA) is a progressive autoimmune disorder characterized by aberrant T-cell activation with clinical outcomes often hindered by adverse effects and inadequate remission.. While mesenchymal stem cellderived extracellular vesicles (MSC-EVs) hold promise for the treatment of autoimmune disorders, the mechanisms by which cytokine priming enhances their efficacy remain poorly characterized.. In this study, we investigated the immunomodulatory effects of EVs derived from interferon-gamma (IFN-γ)-primed MSCs (IFN-γ-EVs) in a collagen-induced arthritis (CIA) murine model.

    Article Title: Wutou decoction ameliorates rheumatoid arthritis through inhibiting hypoxia-induced invasive phenotype of fibroblast-like synoviocytes mediated by the Notch pathway.
    Article Snippet: Ethnopharmacological relevance: Despite its long history of use in traditional medicine for joint disorders, Wutou Decoction (WTD) has not been widely adopted as a complementary therapy for rheumatoid arthritis (RA) in modern practice.. This is primarily due to a lack of robust pharmacological evidence and a clear understanding of its mechanisms of action.. Further investigation into the mechanistic basis of WTD is essential to validate its efficacy and safety in the treatment of RA.
