What tissue is affected by 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 organelle causes rheumatoid arthritis?
A new field of scientific research is examining the role that mitochondria play as a trigger of inflammation in conditions such as systemic lupus erythematous (SLE) and rheumatoid arthritis.
What structures are involved in arthritis?
Anatomy of Arthritis Pain
- Joint capsule: Each joint has a casing surrounding it called a capsule.
- Synovium: The joint capsule has a thin lining on its inner surface called the synovium. …
- Muscles, ligaments and tendons: These structures surround, support and protect the joints.
What cells are involved in rheumatoid arthritis?
In RA, the main function of T-cells is to activate macrophages and fibroblasts and transform them into tissue-destructive cells. Similar to T- and B-cells, activated macrophages produce a variety of cytokines and chemokines to support the inflammation in the joints.
What is the main cause of rheumatoid arthritis?
Rheumatoid arthritis is an autoimmune condition, which means it’s caused by the immune system attacking healthy body tissue. However, it’s not yet known what triggers this. Your immune system normally makes antibodies that attack bacteria and viruses, helping to fight infection.
What cells causes inflammation in rheumatoid arthritis?
T cells and B cells are two types of white blood cells involved in rheumatoid arthritis. The T cells release cytokines (chemicals that play a role in the inflammatory response) and cause the B cells to release antibodies (immune proteins), which causes inflammation.
What is the typical joint involvement with rheumatoid arthritis?
The joints involved most frequently are the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints of the hands, the wrists, and small joints of the feet including the metatarsophalangeal (MTP) joints. The shoulders, elbows, knees, and ankles are also affected in many patients.
What is the basic pathogenic process in rheumatoid arthritis?
Rheumatoid arthritis (RA) is a chronic symmetric polyarticular joint disease that primarily affects the small joints of the hands and feet. The inflammatory process is characterized by infiltration of inflammatory cells into the joints, leading to proliferation of synoviocytes and destruction of cartilage and bone.
What is RA in anatomy?
Rheumatoid arthritis (RA) is a long-term (chronic) disease that causes inflammation of the joints. The inflammation can be so severe that it affects how the joints and other parts of the body look and function. In the hand, RA may cause deformities in the joints of the fingers.
What type of immune response is rheumatoid arthritis?
Thus, RA is characterized by evidence of disordered innate immunity, including immune complex-mediated complement activation, adaptive immune responses against ‘self’-antigens comprising predominantly post-translationally modified proteins, dysregulated cytokine networks, osteoclast and chondrocyte activation and …
How can rheumatoid arthritis be prevented?
