Mechanism of action

Tacrolimus binds to the immunophilin FKBP12, and this complex inhibits calcineurin phosphatase activity. This prevents dephosphorylation and nuclear translocation of NFAT (nuclear factor of activated T cells), blocking the production of IL-2, IFN-γ, and other cytokines essential for T-cell proliferation and immune response. Low-dose formulations are used to minimize systemic immunosuppression while maintaining therapeutic benefit in specific indications.
