Rheumatological diseases

Our immune system is an amazing network of cells that function from very basic to highly complex levels. The purpose of this system is to protect us from our environment and watch for any early damage in our own cells. Sometimes, however, the system goes awry and misreads signals. As a result, our defenses do not recognize our own body at work, and begin “attacking” cells. This leads to illnesses called autoimmune (self-immune) diseases such as rheumatoid arthritis (inflammation of the joints), systemic lupus erythematosus (commonly known as “lupus,” an inflammatory disease of connective tissue), and vasculitis (inflammation of a vessel of the body).
