Summary: This study found that 6-shogaol inhibits proliferation, migration, and invasion, and induces apoptosis in rheumatoid arthritis fibroblast-like synoviocytes (FLSs). It also reduces the production of inflammatory cytokines and matrix metalloproteinases (MMPs). Molecular mechanism analysis revealed that 6-shogaol inhibits the PI3K/AKT/NF-kappa B pathway by activating PPAR-gamma. Treatment with 6-shogaol ameliorated joint destruction in a mouse model of collagen-induced arthritis (CIA). Therefore, 6-shogaol may be a potential natural drug for future rheumatoid arthritis treatments.

Summary: Fibroblast-like synoviocytes (FLS) are the main cell component in inflamed joints of patients with rheumatoid arthritis (RA) and interact with infiltrating T cells. Under normal conditions, FLS have inhibitory effects on T cells, but in RA, FLS exhibit a proinflammatory phenotype. The signals that control FLS heterogeneity are still unclear.

Summary: The study reveals that PTEN methylation promotes inflammation and activation in fibroblast-like synoviocytes (FLS) in the pathogenesis of rheumatoid arthritis (RA). Inhibiting methylation can reduce inflammation and alleviate joint swelling, potentially serving as an effective treatment strategy for RA.

Summary: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease with increasing incidence globally. The study revealed that miR-4423-3p is downregulated in RA patients and targets MMP13 to inhibit cell proliferation, migration, and invasion while promoting apoptosis in HFLS-RA cells.

Summary: The study found that ATT has potential therapeutic effects on RA by suppressing proliferation, migration, and invasion of RA-FLSs, as well as inducing apoptosis. ATT achieves therapeutic potential for RA by modulating the METTL3/ICAM2/PI3K/AKT/p300 feedback loop.

Summary: Synovial samples from RA patients and normal controls were used to isolate FLSs. Increased expression of circ_0007707 was observed in synovial samples from RA patients and FLS-RA cells. Circ_0007707 silencing inhibited cell proliferation, induced cell apoptosis, and decreased cell inflammatory response in FLS-RA cells. Mechanistically, circ_0007707 mediated cell apoptosis and inflammatory response in FLS-RA cells through the miR-27b-3p/PDE3B axis.

Summary: Our study demonstrates the impact of TNF-alpha on cAMP homeostasis and the interaction between TNF-alpha and EP4 signaling, revealing the potential role of TRAF2 and GRK2 in the treatment of inflammatory diseases. The findings provide valuable insights into a novel form of cross-talk between cytokine receptors and G protein-coupled receptors, suggesting TRAF2-GRK2 interaction as a potential new drug target.

Summary: Fibroblast-activated protein-a (FAP) is overexpressed by activated fibroblasts during fibrosis or inflammation. It plays important roles in regulating the cellular responses in the synovial region of rheumatoid arthritis (RA), and its overexpression is regulated by the initial inflammatory microenvironment and epigenetic signaling. Targeted therapies for FAP are currently being developed. This review discusses the features of FAP in FLSs and its role in RA pathophysiology, as well as advances in targeted therapies.

Summary: Wutou Decoction (WTD) has shown to ameliorate symptoms and synovial pannus hyperplasia in collagen-induced arthritis (CIA) rats, inhibit proliferation, migration and invasion of MH7A cells, induce apoptosis, and block proangiogenic factors. The potential mechanism of WTD in inhibiting angiogenesis in rheumatoid arthritis (RA) is likely through the PI3K-AKT-mTOR-HIF-1 alpha pathway.
