Our immune system keeps us healthy by fighting off bacteria, viruses, and other pathogens that cause infection and disease. Inflammation is the immune system’s response to a problem such as a germ or physical injury. Inflammation may be experienced as redness, swelling, or pain.
In certain cases, the immune system mistakenly targets a part of the body that it believes is harmful. The mistaken immune response commonly results in inflammation and damage to healthy tissues. This is known as an autoimmune disease.
An example of an autoimmune disease is rheumatoid arthritis (RA). RA occurs when the immune system attacks the lining of the joints, causing painful swelling. Over a long period of time, inflammation from RA can cause joint and bone damage.
We continue to develop new treatments to control inflammation and autoimmune conditions, in the hopes of reducing the toll that they take on people’s lives. Clinical trials are an important part of this effort. We invite you to explore our clinical trials in inflammation and immunology below.
