REVIEW
 An immunosuppressant drug used to prevent rejection in organ transplantation. Sirolimus inhibits the response to interleukin-2 (IL-2), and thereby blocks activation of T and B cells. In contrast, tacrolimus inhibits the secretion of IL-2. The mode of action of sirolimus is to bind the cytosolic protein FK-binding protein 12 (FKBP12) in a manner similar to tacrolimus. Unlike the tacrolimus-FKBP12 complex which inhibits calcineurin (PP2B), though, the sirolimus-FKBP12 complex inhibits the mammalian target of rapamycin (mTOR) pathway by directly binding the mTOR Complex1 (mTORC1).
