Pharmacology
Abatacept is a selective T-cell costimulation modulator that inhibits T-lymphocyte activation by binding to CD80 and CD86, thereby blocking the CD28 costimulatory interaction required for full T-cell activation; activated T lymphocytes are implicated in the pathogenesis of RA, pJIA, and PsA.
Methotrexate inhibits dihydrofolic acid reductase, interfering with DNA synthesis, repair, and cellular replication by blocking reduction of dihydrofolates to tetrahydrofolates required for purine nucleotide and thymidylate synthesis; the mechanism in pJIA is unknown but may affect immune function.
