Oral rapamycin inhibits growth of atherosclerotic plaque in apoE knock-out mice.

Introduction: Inflammatory and immunological responses of vascular cells are known to play significant roles in atherosclerotic plaque development. Rapamycin with antiinflammatory, immunosuppressive and antiproliferative properties has been shown to reduce neointima formation when coated on stents. This study is designed to test the potential of oral rapamycin to inhibit atherosclerotic plaque development.
