Which drug is an mTOR kinase inhibitor used in the context of transplantation?

Everolimus is an mTOR kinase inhibitor used in the context of transplantation. Cyclosporine and basiliximab work by suppressing the immune system, whereas mycophenolate mofetil is an immunosuppressant that works by inhibiting the production of DNA in immune cells. Although these options are commonly used in transplantation, they are not mTOR kinase inhibitors. Therefore, they are not the correct answer.
