iNKT cells require TSC1 for terminal maturation and effector lineage fate decisions

Abstract excerpt

Terminal maturation of invariant NKT (iNKT) cells from stage 2 (CD44+NK1.1-) to stage 3 (CD44+NK1.1+) is accompanied by a functional acquisition of a predominant IFN-γ-producing (iNKT-1) phenotype; however, some cells develop into IL-17-producing iNKT (iNKT-17) cells. iNKT-17 cells are rare and restricted to a CD44+NK1.1- lineage. It is unclear how iNKT terminal maturation is regulated and what factors mediate...
