How Does It Work?
Tacrolimus works by suppressing the activation of T-cell and T-helper-cell dependent B-cell proliferation and the formation of lymphokines and the expression of the IL-2 receptor. It inhibits calcineurin’s activity by binding to an intracellular protein, FKBP-12, forming a complex with calcium, calmodulin, and calcineurin.
