title: CD8+ T-cell senescence: no role for mTOR.
abstract: Aging is accompanied by immune decline leading to increased incidence of infections and malignancies, given the demographic shift of humans towards an older age the identification of strategies for the manipulation of immunity is an important goal. Evidence implicates mammalian target of rapamycin (mTOR) to be a key modulator of aging and the use of mTOR inhibitors has been shown to ameliorate much age-related pathology; however, recent data suggest that senescent CD8(+) T-cells function independently of mTOR. This review article will challenge the perceived dogma that mTOR universally controls CD8(+) T-cell function.
