IMMUNOSUPPRESSIVE AGENT MECHANISM OF ACTION
CALCINEURIN INHIBITORS Inhibit signal 2 trasduction via T cell receptor
MAMMALIAN TARGET OF RAPAMYCIN INHIBITORS Inhibit signal 3 trasduction via IL-2 receptor
MYCOPHENOLIC ACID Inhibits purine and DNA synthesis
CORTICOSTEROIDS Inhibit cytokine transcription by antigen presenting cell; Selective lysis of immature cortical thymocytes
AntiCD3 monoclonal antibodies Depletion and receptor modulation in T cell Interferes with signal 1
Antithymocyte globuline Depletion and receptor modulation in T cells Interferes with signal 1, 2, 3 Inhibits lymphocytes trafficking
Anti IL-2 alpha chain receptor antibodies Inhibit T cell proliferation to IL-2
Anti –CD52 monoclonal antibodies Cause depletion of thymocytes, T cells, B cells and monocytes
