AI Article Synopsis

  • Fibroblast-like synoviocytes (FLS) are key cells in the synovial membrane of joints, crucial for maintaining normal joint function by producing important substances.
  • In conditions like rheumatoid arthritis (RA), FLS can become overactive and contribute to chronic inflammation and joint damage.
  • Targeting FLS may offer therapeutic benefits for autoimmune joint disorders without the side effects associated with traditional immunosuppressive treatments.

Article Abstract

Fibroblast-like synoviocytes or synovial fibroblasts (FLS) are important cellular components of the inner layer of the joint capsule, referred to as the synovial membrane. They can be found in both layers of this synovial membrane and contribute to normal joint function by producing extracellular matrix components and lubricants. However, under inflammatory conditions like in rheumatoid arthritis (RA), they may start to proliferate, undergo phenotypical changes and become central elements in the perpetuation of inflammation through their direct and indirect destructive functions. Their importance in autoimmune joint disorders makes them attractive cellular targets, and as mesenchymal-derived cells, their inhibition may be carried out without immunosuppressive consequences. Here, we aim to give an overview of our current understanding of the target potential of these cells in RA.

Rheumatoid arthritis (RA) is an important autoimmune disease that affects synovial tissues, accompanied by redness, pain, and swelling as main symptoms, which will limit the quality of daily life and even cause disability. Multiple coupling effects among the various cells in the synovial micro-environment modulate the poor progression and development of diseases. Respectively, synovium is the primary target tissue of inflammatory articular pathologies; synovial hyperplasia, and excessive accumulation of immune cells lead to joint remodelling and destroyed function.

Rheumatoid arthritis (RA) is a prevalent autoimmune disease characterized by chronic inflammation and excessive proliferation of the synovium. Currently, treatment options focus on either reducing inflammation or inhibiting synovial hyperplasia. However, these modalities are unsatisfactory in achieving the desired therapeutic outcomes.

Extracellular vesicles from Rheumatoid arthritis (RA) derived synovial fibroblasts (EVs) have been implicated in the pathogenesis of RA, acting as mediators of cell-to-cell communication. This study aimed to elucidate the role of the chemokine receptor CCR5 and EVs positive for CCR5 (EVs) in RA, focusing on their impact on cartilage destruction and bone erosion in a rat model of Adjuvant-induced arthritis (AIA). In vivo experiments were conducted using AIA rats, treated with either EVs, EVs without CCR5 (EVs), or EVs which encapsulated the CCR5 antagonist Maraviroc.

Rheumatoid arthritis (RA) is a chronic autoimmune disorder marked by pain, inflammation, and discomfort in the synovial joints. It is critical to understand the pathological mechanisms of RA progression. MicroRNA-378 (miR-378) is highly expressed in the synovium of RA patients and positively correlated with disease severity, but its function and underlying mechanisms remain poorly understood.

Objective: Uncontrolled pain remains a major clinical challenge in the management of knee osteoarthritis (OA), the most common disabling joint disease. Worse pain is associated with synovial innate immune cell infiltration (synovitis), but the role of innate immune regulatory cells in pain is unknown. Our objective was to identify synovial innate immune cell subsets and pathophysiologic mechanisms associated with worse pain in patients with knee OA.
