Mechanism of action

Tacrolimus binds to the immunophilin FKBP12, and this complex inhibits calcineurin phosphatase activity. By blocking calcineurin, it prevents dephosphorylation and nuclear translocation of NFAT (nuclear factor of activated T cells), which is essential for IL-2 and other cytokine gene transcription. This results in potent immunosuppression, making it effective for preventing organ rejection and treating autoimmune conditions.
