If the accumulation of these cells continues, the movement will be limited and eventually the disease will develop to the next stage. Furthermore, white blood cells release inflammatory mediators that start forming the pannus, which is an inflammatory synovial tissue that covers the cartilage and destroys it. [5] The third stage is a severe stage that causes a complete destruction of the cartilage. This happens when the pannus release enzymes that cause an erosion around the edge of the joints, so it will lose its moving ability. After that, the fourth stage or the end stage of rheumatoid arthritis comes causing a destruction and loss in the density of the bones, not only in the area that surrounds the affected joints but also in all of the body. Moreover, the neutrophils, which is a type of the white blood cells, worsen the inflammation in the joint. According to the Rheumatology Oxford Journal, "not only are neutrophils found in high numbers within the rheumatoid joint, both in synovial tissue and in joint fluid." [6] For this reason, neutrophils play a huge role in the cartilage and bone destruction that happen in the third and fourth stages.
To sum up, researchers help people understand the disease by dividing rheumatoid arthritis into four stages and each stage has its characteristics that differentiate it from other
