Summary: This study analyzed the cellular composition of synovial tissue from RA and control patients and found higher proportions of lymphocytes and myeloid cells in RA synovial tissue compared to controls. Additionally, there was a decrease in the proportion of CD200(+)CD105(-) cells and an increase in CD200(-)CD105(+) cells in RA synovial tissue. These cell populations were associated with inflammatory activity and could differentiate between RA and control patients.

Summary: Rheumatoid arthritis (RA) is characterized by chronic inflammation, bone erosion, and joint deformation. IL-26, a member of the IL-10 family, is overexpressed in RA patients and plays a role in promoting IL-17A expression. IL-26 stimulates the expression of IL-9 and IL-17A in macrophages and activates the AKT-FoxO1 pathway. Targeting IL-26 may be a potential therapeutic strategy for RA and other diseases with IL-9 and IL-17 dominance.

Summary: The study found that 43% of rheumatoid arthritis patients treated with RTX developed HGG. Patients who developed low IgG or low IgM had lower baseline levels than those who did not, and the development of low IgM was associated with better disease outcomes.

Summary: IL-40 is up-regulated in seropositive ERA and decreases after conventional therapy. Neutrophils are an important source of IL-40 in RA, and its release is potentiated by cytokines and NETosis. IL-40 may play a role in ERA.

Summary: Neutrophil extracellular traps (NETs) are early triggers of pathogenic inflammation in periodontitis, a prevalent oral inflammatory disease. NETs promote IL-17/Th17 immune response and contribute to bone destruction. Human findings support the role of NET-mediated pathology in periodontitis.

Summary: This study identified a novel IL-17A/F-derived peptide and generated a new anti-IL-17 antibody that can effectively reverse the pro-inflammatory actions of IL-17A/F. The antibody showed less off-target effects compared to the current gold-standard biologic. Preclinical and clinical evidence demonstrated the high efficacy and therapeutic potency of the antibody in patients with IMIDs.

Summary: IL-4 and IL-13 are key mediators of allergic inflammation and have been implicated in the development of autoimmune diseases. Recent studies suggest that they may play a significant role in downregulating inflammatory processes underlying rheumatoid arthritis pathogenesis.

Summary: The study revealed a direct role of TNF in the glycolytic reprogramming of FLS, confirming the potency of immunometabolism in RA. TNF stimulation was shown to enhance glycolysis, reduce GLUT1 and GAPDH levels, which may be linked to treatment response in patients.

Summary: This study aimed to evaluate the efficacy and safety of TAS5315 in Japanese patients with refractory rheumatoid arthritis. The results showed numerical differences in disease activity improvement rates between the TAS5315 group and the placebo group at week 12, but the primary endpoint was not achieved. However, TAS5315 demonstrated advantages in disease activity and biomarker improvement, as well as higher risk of bleeding events within 36 weeks. Therefore, a risk-benefit analysis of TAS5315 should be considered.

Summary: The study demonstrates that Antcin K, a compound isolated from Antrodia cinnamomea, shows anti-inflammatory effects by inhibiting proinflammatory cytokine production in human rheumatoid synovial fibroblasts. This indicates the potential of Antcin K in treating rheumatoid arthritis by reducing inflammation.

Summary: Transcriptomic analysis revealed that microRNA-132 is induced specifically in Th17 cells in the presence of AhR agonist or CS-enriched medium. This induced miRNA132 acts as a proinflammatory mediator by promoting osteoclastogenesis through down-regulating COX2, exacerbating the development of RA.

Summary: Circulating free-cell miRNAs have become increasingly important as potential non-invasive biomarkers, particularly in the field of oncology. This research aimed to investigate the association between selected miRNAs in serum and the expression of Th17/Treg transcription factors, as well as clinical features, in rheumatoid arthritis (RA) patients. The study found that miR-10 was only detected in RA patients and its expression was correlated with IL-35 serum concentration and STAT5a mRNA level. Additionally, miR-326 was significantly upregulated in RA patients with rheumatoid factor presence. The differential association of transcription factor expression with serum miRNA levels may have implications for the diagnosis and progression of RA and osteoarthritis (OA).

Summary: The study revealed that systemic overexpression of IL-22 has clear anti-inflammatory effects during collagen-induced arthritis, with reduced disease severity and incidence. Additionally, the protective effect of systemic IL-22 is likely mediated through upregulation of the negative immune regulator SOCS3.
