Mechanism of action

Both drugs bind to immunophilins (cyclophilin for cyclosporine, FKBP for tacrolimus) and inhibit calcineurin phosphatase, preventing dephosphorylation and nuclear translocation of NFAT transcription factors. This blocks IL-2 and other cytokine production, suppressing T-cell proliferation and immune response. Tacrolimus is approximately 10-100 times more potent than cyclosporine.
