| - Belatacept is a soluble fusion protein, which links the extracellular domain of human cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) to the modified Fc (hinge, CH2, and CH3 domains) portion of human immunoglobulin G1 (IgG1). Structurally, abatacept is a glycosylated fusion protein with a MALDI-MS molecular weight of 92,300 Da and it is a homodimer of two homologous polypeptide chains of 357 amino acids each. It is produced through recombinant DNA technology in mammalian CHO cells. The drug has activity as a selective co-stimulation modulator with inhibitory activity on T lymphocytes. It is approved for the treatment of rheumatoid arthritis. Belatacept selectively blocks the process of T-cell activation. It was developed by Bristol-Myers-Squibb. It differs from abatacept (Orencia) by only 2 amino acids. FDA approved on June 15, 2011. (en)

| http://linked.open...mechanismOfAction
| - Belatacept is a fusion protein in which the Fc portion of human IgG1 is attached onto the extracellular portion of human CTLA-4 (CD152). Belatacept specifically binds to CD80 and CD86 receptors that are found on the antigen-presenting cell (B cells, macrophages, dendritic cells) to block selective T-cell lymphocyte costimulation. CD80 and CD86 would normally act as the ligands to the CD28 receptor T-cells in which this interaction triggers the activation of T lymphocytes. However in the presence of belatacept, because the extracellular CTLA-4 component binds to CD28 with higher affinity than CD80 or CD86, T lymphyocyte anergy, a state of antigen specific tolerance, occurs instead. The T cell is also no longer able to respond to their antigen. (en)
