mTOR

…mammalian target of rapamycin, or mTOR, which is involved in regulating growth and life span. The ability of rapamycin to inhibit the mTOR cell-signaling pathway is suspected to underlie the drug’s ability to extend the life span of mice.

…mammalian target of rapamycin (mTOR), a kinase (an enzyme that adds phosphate groups to other molecules) that plays a fundamental role in regulating the progression of the cell cycle. The rapamycin complex inhibits mTOR and, by doing so, disrupts cell division and hence the proliferation of T cells.
