The protein known as mammalian target of rapamycin (mTOR) plays vital roles in protein synthesis, and hence in growth and cell proliferation, including the proliferation of immune response cells and neoplastic cells. The paths through which it acts have two main branches that start from mTOR complexes known as mTORC1/RAPTOR and mTORC2/RICTOR. The former is inhibited by sirolimus (rapamycin), everolimus, and their analogues, while the latter is not. Despite not inhibiting mTORC2/RICTOR, the sirolimus family are known collectively as mTOR inhibitors, and also as proliferation signal inhibitors (PSIs).1
mTOR inhibitors are attractive for post-transplantation therapy because their antiproliferative properties appear to combine immunosuppression
