Abatacept, sold under the brand name Orencia, is a medication used to treat autoimmune diseases like rheumatoid arthritis, by interfering with the immune activity of T cells. It is a modified antibody.
Abatacept is used to treat autoimmune diseases like rheumatoid arthritis, by interfering with the immune activity of T cells. Abatacept is a fusion protein composed of the Fc region of the immunoglobulin IgG1 fused to the extracellular domain of CTLA-4. In order for a T cell to be activated and produce an immune response, an antigen-presenting cell must present two signals to the T cell. One of those signals is the major histocompatibility complex (MHC), combined with the antigen, and the other signal is the CD80 or CD86 molecule. Abatacept binds to the CD80 and CD86 molecule, and prevents the second signal. Without the second signal, the T cell can’t be activated. It also used to treat psoriatic arthritis and juvenile idiopathic arthritis.
