Triptolide (TP) exhibits immunosuppressive, cartilage-protective and anti-inflammatory effects in rheumatoid arthritis. However, the toxicity of TP limits its widespread use. To decrease the toxic effects, we developed a novel nano-drug carrier system containing TP using poly-γ-glutamic acid-grafted di-tert-butyl L-aspartate hydrochloride (PAT). PAT had an average diameter of 79±18 nm, a narrow polydispersity index (0.18), a strong zeta potential (-32 mV) and a high drug encapsulation efficiency (EE1 =48...

OBJECTIVE: Rheumatoid arthritis (RA) is a chronic, autoimmune and degenerative joint disease leading to disability, reduced life quality, and increased mortality. Although several synthetic and biological disease modifying anti-rheumatic drugs (DMARDs) are available, there is still a medical need for novel drugs controlling disease progression. As only 10% of RA drug candidates that enter phase I trials are eventually FDA registered, there is an immediate requirement for translational drug development tools to facilitate early drug development decision making...

INTRODUCTION: Rheumatoid arthritis (RA) represents the most commonly occurring inflammatory type of arthritis and is a major cause of disability. Reports have placed emphasis on the potential of, granzyme B (GZMB) as a potentially valuable prognostic marker in early RA, the mechanism of which still remains largely unclear. Thus, the aim of the current study was to investigate the effects GZMB gene silencing influences synovial tissue hyperplasia and articular cartilage tissue injury of RA through the regulation of the MAPK signaling pathway...

Interleukin (IL)-15 is an inflammatory cytokine that constitutes a validated therapeutic target in some immunopathologies, including rheumatoid arthritis (RA). Previously, we identified an IL-15 antagonist peptide named [K6T]P8, with potential therapeutic application in RA. In the current work, the metabolic stability of this peptide in synovial fluids from RA patients was studied. Moreover, [K6T]P8 peptide was labeled with 99m Tc to investigate its stability in human plasma and its biodistribution pattern in healthy rats...

OBJECTIVE: Inhibitory receptors (IRs) are essential to regulate effector immune responses and may play critical roles during autoimmune diseases. In Rheumatoid Arthritis (RA), we evaluated whether IR expression on T cells showed correlation with immune activation, disease activity and response to treatment as well as if IR-mediated pathways were functional. METHODS: By flow cytometry, we performed extensive phenotypic and functional evaluation of CD4+ and CD8+ T cells from blood and synovial fluid of RA patients ex vivo and after culture...

BACKGROUND: The pathogenesis of osteoarthritis (OA) is not clear; leptin may be related to its pathogenesis. METHODS: We reviewed articles on leptin in OA, chondrocytes, and in vitro experiments. It is concluded that leptin may lead to OA via some signaling pathways. At the same time, the concentration of leptin in vitro experiments and OA/rheumatoid arthritis (RA) patients was summarized. RESULTS: Leptin levels in serum and synovial fluid of OA/RA patients were higher than normal person...

Mesenchymal TNF signaling is etiopathogenic for inflammatory diseases such as rheumatoid arthritis and spondyloarthritis (SpA). The role of Tnfr1 in arthritis has been documented; however, Tnfr2 functions are unknown. Here, we investigate the mesenchymal-specific role of Tnfr2 in the TnfΔARE mouse model of SpA in arthritis and heart valve stenosis comorbidity by cell-specific, Col6a1-cre-driven gene targeting. We find that TNF/Tnfr2 signaling in resident synovial fibroblasts (SFs) and valvular interstitial cells (VICs) is detrimental for both pathologies, pointing to common cellular mechanisms...

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of synovial tissues in joints, leading to progressive destruction of cartilage and joints. The disease-modifying anti-rheumatic drugs currently in use have side-effects. Thus, there is an urgent need for safe anti-inflammatory therapies for RA. This study aimed to evaluate the therapeutic effect of the flavonoid quercetin on arthritis in mice immunized with type II collagen (CII). An arthritis model was established in C57/BL6 mice by intradermal administration of chicken CII mixed with Freund's complete adjuvant...

Local delivery of therapeutics for the treatment of inflammatory arthritis (IA) is limited by short intra-articular half-lives. Since IA severity often fluctuates over time, a local drug delivery method that titrates drug release to arthritis activity would represent an attractive paradigm in IA therapy. Here we report the development of a hydrogel platform that exhibits disassembly and drug release controlled by the concentration of enzymes expressed during arthritis flares. In vitro, hydrogel loaded with triamcinolone acetonide (TA) releases drug on-demand upon exposure to enzymes or synovial fluid from patients with rheumatoid arthritis...

Rheumatoid arthritis (RA) is a chronic inflammatory disease that can potentially damage the synovial joints. One of the effective treatment modality for RA is radiation synovectomy (RSV) where properly selected radionuclide is injected into the joint space, enabling controlled destruction of diseased synovial membrane via radiation exposure. Radiation dosimetry in RSV appears challenging due to the heterogeneous nature of synovial membrane, nonuniform distribution and leakage of radionuclide from the synovial cavity...

Rheumatoid arthritis is an autoimmune disease manifested by a persistent inflammation of synovial joints, bone destruction, loss of cartilage and increased risk of cardiovascular and other intercurrent diseases. The treatment of rheumatoid arthritis should be based on the strategy of treat to target therapy which is achieving remission, in some cases low activity of the disease. Essential to the treat to target therapy are more frequent checkups and optimization of treatment based on disease activity. Methotrexate continues to be the essential medicine from the group of disease modifying antirheumatic drugs for rheumatoid arthritis treatment...

The target of treatment for rheumatoid arthritis (RA) is to keep low disease activity or remission. Tocilizumab can fully inhibit interleukin-6 and C reactive protein (CRP) production. The goal of the study is to search whether tocilizumab treatment compared with adalimumab treatment had the similar effect on sonography and inflammatory parameters in patients with RA. We compared ultrasound scores and inflammatory parameters between patients with RA receiving tocilizumab therapy and those receiving adalimumab therapy...
