How does this medication work?
Tacrolimus suppresses cellular immunity (inhibits T-lymphocyte activation), by binding to an intracellular protein, FKBP-12, and complexes with calcineurin dependent proteins to inhibit calcineurin phosphatase activity. Inhibition of calcineurin also is important in maintaining neuronal and synaptic integrity and homeostasis for peripheral nerve regeneration.
