Protein complex that catalyzes two steps in prostaglandin biosynthesis.
Type of drug called an alkylating agent that is also used as an immunosuppressant to treat autoimmune diseases such as severe, refractory rheumatoid arthritis. Also used to treat severe complications of lupus, myositis, scleroderma, and vasculitis. It was first developed as a cancer drug. Blocks the production of DNA inside certain types of cells, including immune cells. The cells then die, and they can no longer play a role in certain autoimmune diseases. May have severe side effects, including nausea and vomiting, and may also increase the risk of certain infections, such as herpes zoster or shingles.

Used to prevent organ rejection in people who have received a liver, kidney, or heart transplant. It is usually taken along with other medications to allow the new organ to function normally. Also used to treat severe rheumatoid arthritis (RA) and a certain skin condition (severe psoriasis). Belongs to a class of drugs known as immunosuppressants, and works by slowing down the body’s defense system (immune system) to prevent the body from rejecting a transplanted organ, further damaging the joints (in RA patients), or further damaging the skin (in psoriasis patients). For the treatment of psoriasis or arthritis, it is generally used to treat people who cannot take other medications or have not found relief from other treatments.
Any of numerous hormone-like, low-molecular-weight proteins, secreted by various cell types, that regulate the intensity and duration of immune response and mediate cell-cell communication.
Derivative of operations research and game theory that involves identifying all available choices and the potential outcomes of each, in a series of decisions that have to be made about patient care—diagnostic procedures, therapeutic regimens, and prognostic expectations; the range of choices can be plotted on a decision tree.
