Signaling through the costimulatory pathway is critical in the regulation of T cell activation. Abatacept, a selective costimulatory antagonist FDA approved for the treatment of moderate to severe rheumatoid arthritis, binds to CD80 and CD86 on antigen presenting cells, blocking the interaction with CD28 on T cells. Belatacept, a second generation CTLA4-Ig with 2 amino acid substitutions, has shown considerable promise in clinical transplantation as part of a maintenance immunosuppression regimen. This review will summarize the role of costimulation in T cell activation, detail the development of costimulation antagonists and highlight the pertinent clinical trials completed and ongoing utilizing belatacept as part of an immunosuppressive regimen in organ transplantation.
