Slide 7: Detailed Pathophysiology – antibody Formation

• This slide begins the detailed explanation of the autoimmune process in Rheumatoid Arthritis.
• It focuses on the creation of the two signature autoantibodies, anti-CCP and Rheumatoid Factor (RF).

1. Anti-CCP Antibody Formation (Point 1): Explains that IgG antibodies attack the cyclic citrullinated peptides (Citulline Antigens), resulting in the formation of the anti-CCP antibody. The visual clearly shows the IgG antibodies interacting with citrulline antigens and forming the anti-CCP structure.
2. Rheumatoid Factor (RF) Formation (Point 2): Explains that IgM antibodies attack the IgG antibodies themselves, leading to the formation of rheumatoid factor (RF). The visual illustrates IgM attacking IgG to create the complex RF structure.

‍

Slide 8: Pathophysiology – Antibody Migration to Joints

• This slide details the mechanism by which the autoimmune process translates into joint inflammation.
• It maintains the visual theme, using a magnified view of a healthy joint (synovial joint) surrounded by the purple hand outline and autoantibody graphics.

• The key message is that Both CCP antibodies and rheumatoid factors travel through the blood to the joints.
• This slide serves as the vital link between the molecular production of the antibodies (from the previous slide) and the site of clinical disease manifestation (the joint), setting up the next step of the inflammatory cascade within the joint itself.

‍

Slide 9: Pathophysiology – Inflammatory Cascade and Cytokine Release

• This slide details the critical cellular events that follow the autoantibodies entering the joint space.
• It focuses on the activation of key immune cells (phagocytes) and the release of inflammatory mediators.

• The left side shows the autoantibodies (CCP and RF) residing within the joint's synovial fluid.
• The right side prominently displays two types of activated phagocytes: a Macrophage and a Dendritic cell.
• The central text explains that "The activated phagocytes release inflammatory cytokines, such as TNF\alpha, IL1, IL6, and interferon gamma."

‍

Slide 10: Pathophysiology – Complement Activation and Neutrophil Recruitment

• This slide details the role of the complement system and neutrophils in the Rheumatoid Arthritis inflammatory process.

• The left side shows the autoantibodies (CCP and RF) bound within the joint capsule.
• Neutrophils are shown migrating into the synovial fluid. Macrophages and Dendritic cells remain on the right.
• The central text explains that "The complement enzymes activate neutrophils in the synovial fluid."
