The mammalian Target of Rapamycin (mTOR) protein controls the machinery necessary for T‐cell activation, differentiation, and memory formation, as a component of mTOR complex 1 (mTORC1) and mTORC2, which function both downstream and upstream of AKT. Invariant natural killer T (iNKT) cells are a unique T‐cell subset that exist in a primed state, capable of rapid activation, and produce large quantities of cytokines. iNKT‐cell effector differentiation is dependent on the mTORC1 complex; however, the requirements for mTORC2 in iNKT cells have been controversial. In this issue, Sklarz et al. [Eur. J. Immunol. 2017. 47: 516–526] provide a careful analysis of the requirements for the mTORC2 component Rictor in iNKT cells, providing a new twist in this unfolding tale. The authors demonstrate that Rictor is required for iNKT‐cell proliferation and survival during the key stage of intrathymic expansion and that Rictor supports the development of NKT17 cells, an effector subset which depends on the transcription factor RORγt and produces interleukin (IL)‐17, in both the thymus and the lung. IL‐4‐producing NKT2 cells develop in the absence of Rictor but the cytotoxic potential of iNKT cells is Rictor‐dependent.
