    ..These findings show that education-dependent NK cell survival advantages and killing of uneducated NK cells result in the maintenance of a functional repertoire, which may be manipulated to exploit NK cells for cancer immunotherapy. ..

    ..We therefore conclude that although GATA3 allows Th17 differentiation, it acts as an inhibitor of Th17-mediated pathology, through IL-4-dependent and IL-4-independent pathways. ..

    ..Whereas expression of TCRbeta chain genes is readily detectable in the mutant thymus, no expression of the TCRgamma chain was detectable. Our results identify a new genetically defined control point of thymopoiesis. ..
