Macrophages are called scavenger cells because they clean up the mess left by B cells and T cells by eating up antigen particles left in the blood. They also secrete chemicals called cytokines that signal the immune system to either rev up or slow down its attack. In rheumatoid arthritis and many other forms of arthritis, a dysregulation of these chemicals and their signals contributes to symptoms and damage.
Neutrophils are white blood cells that fight infection and produce powerful enzymes that break down cell debris in the blood. These enzymes can be so virulent, in fact, that they can damage the synovial membranes that line the joints, and the cartilage that cushions them Neutrophils also produce substances that increase blood flow to the affected area. Increased blood flow and internal fluids cause the affected joints to swell, and deliver other white blood cells that take part in the damaging attack, generally known as inflammation. Unless the immune system’s attack is stopped, rheumatoid arthritis can progress to damage not only the synovium but also the joint cartilage, underlying bone, and ligaments and tendons, causing deformity and disability.
