Rheumatoid arthritis (RA) is a systemic inflammatory disease mainly characterized by synovitis and joint destruction. Etiology of RA is unknown. Although the impact of genetic factors is obvious, the genetic basis is not sufficient to explain the triggering of the immune insult.

Just so, what are usually the first signs of rheumatoid arthritis?
Signs and symptoms of rheumatoid arthritis may include: Tender, warm, swollen joints. Joint stiffness that is usually worse in the mornings and after inactivity. Fatigue, fever and loss of appetite.
What happens rheumatoid arthritis?
RA commonly affects joints in the hands, wrists, and knees. In a joint with RA, the lining of the joint becomes inflamed, causing damage to joint tissue. This tissue damage can cause long-lasting or chronic pain, unsteadiness (lack of balance), and deformity (misshapenness).
What is pathophysiology of a disease?
Definition of pathophysiology
: the physiology of abnormal states specifically : the functional changes that accompany a particular syndrome or disease.
What is the pathophysiology of arthritis?
In rheumatoid arthritis, the body’s immune system attacks the lining of the joint capsule, a tough membrane that encloses all the joint parts. This lining (synovial membrane) becomes inflamed and swollen. The disease process can eventually destroy cartilage and bone within the joint.
What part of the body does rheumatoid arthritis affect?
It causes inflammation in the lining of your joints (the synovium). As a result, your joints may get red, warm, swollen, and painful. RA affects joints on both sides of the body, such as both hands, both wrists, or both knees. This symmetry helps to set it apart from other types of arthritis.
Which cells have a major role in the pathophysiology of rheumatoid arthritis?
T cells, B cells and the orchestrated interaction of pro-inflammatory cytokines play key roles in the pathophysiology of RA. Differentiation of naïve T cells into Th 17 (TH17) cells results in the production of IL-17, a potent cytokine that promotes synovitis.
