The inhibitory effects of pravastatin on natural killer cell activity in vivo and on cytotoxic T lymphocyte activity in vitro.

Abstract

Pravastatin exerts an immunosuppressive effect in heart transplant recipients as expressed by a reduction in rejection and natural killer cell cytotoxicity. Pravastatin and cyclosporine act synergistically to reduce cytotoxic T lymphocyte activity. This synergistic effect of pravastatin and cyclosporine may explain why this immunosuppressive effect is unique to transplant recipients.
