Brief Summary

The purpose of this study is to determine whether calcineurin phosphatase in the T-lymphocytes is up-regulated after long-term treatment with tacrolimus, a calcineurin inhibitor.

Detailed Description

Background: The immunosuppressive effect of both tacrolimus and cyclosporine is believed to be through inhibition of the enzyme calcineurin phosphatase (CaN) in T-lymphocytes. We have demonstrated, t...
