Abatacept (Orencia) fuzioni protein je koji se sastoji od Fc regiona imunoglobulina IgG1 spojenog sa ekstracelularnim domenom CTLA-4. Ovaj molekul ima veću sposobnost vezivanja za CD80 (B7-1) nego za CD86 (B7-2). Abatacept je selektivni kostimulationi modulator koji inhibira kostimulaciju T ćelija. On se koristi za lečenje reumatoidnog artritisa u slučaju neadekvatnog responsa na anti-TNFα terapiju.[1][2][3][4][5][6][7][8][9][10][11][12]
